Travel Direction (optional) اتجاه
السفر (اختياري)
Specify whether you want
to search for the closest facility as measured from the incident to the facility
or from the facility to the incident.
حدد ما إذا كنت تريد البحث عن أقرب منشأة كما تم
قياسها من الحادثة إلى المنشأة أو من المنشأة إلى الواقعة.
• TRAVEL_FROM - اتجاه السفر من المرافق إلى الحوادث. تستخدم إدارات الإطفاء
عادةً هذا الإعداد ، نظرًا لأنها معنية بالوقت المستغرق للانتقال من محطة الإطفاء
(المنشأة) إلى موقع الطوارئ (الحادث).
• TRAVEL_TO — اتجاه السفر من الحوادث إلى المرافق. عادةً ما تستخدم متاجر
البيع بالتجزئة هذا الإعداد ، نظرًا لأنها معنية بالوقت الذي يستغرقه المتسوقون
(الحوادث) للوصول إلى المتجر (المنشأة).
يمكن أن يؤدي استخدام إحدى قيم المعلمات إلى
العثور على مرافق مختلفة حيث قد يختلف وقت السفر على طول بعض الشوارع بناءً على
اتجاه السفر وقيود الاتجاه الواحد. على سبيل المثال ، قد تكون المنشأة على بعد 10
دقائق بالسيارة من الحادث أثناء السفر من الحادث إلى المنشأة ، ولكن أثناء السفر
من المنشأة إلى الواقعة ، قد تستغرق الرحلة 15 دقيقة بسبب اختلاف وقت السفر في هذا
الاتجاه . إذا كنت تقوم بتعيين قيمة للوقت من اليوم ، فقد تتسبب حركة المرور أيضًا
في إرجاع خياري "التسهيلات الخاصة بالحادث والحادث إلى المنشأة" إلى
نتائج مختلفة.
Time of
Day (optional)
Specifies the time and date at which the routes should begin or end. The
value is used as the start time or end time for the route depending on the
value for the Time of Day Usage parameter. If you specify the current date and
time as the value for this parameter, the tool will use live traffic conditions
to find the closest facilities and the total travel time will be based on
traffic conditions.
If your network dataset contains live or historical traffic data,
specifying a time of day results in more accurate estimation of travel time
between the incident and facility because the travel times account for the
traffic conditions that are applicable for that date and time.
The Time Zone for Time of Day parameter specifies whether this time and
date refer to UTC or the time zone in which the facility or incident is
located.
Irrespective of the Time Zone for Time of Day setting, if your facilities
and incidents are in multiple time zones, the following rules are enforced by
the tool:
· All incidents must be in the same time zone for the following:
o Specifying a start time and traveling from incident to facility.
o Specifying an end time and traveling from facility to incident.
· All facilities must be in the same time zone for the following:
o Specifying a start time and traveling from facility to incident.
o Specifying an end time and traveling from incident to facility.
Time of
Day Usage (optional)
Indicates whether the Time of Day parameter value represents the arrival
or departure time for the routes.
· START_TIME— When this option is chosen, the tool finds the best route
considering the Time of Day parameter value as the departure time from the
facility or incident.
· END_TIME— When this option is chosen, the tool considers the Time of Day
parameter value as the arrival time at the facility or incident. This option is
useful if you want to know what time to depart from a location so you arrive at
the destination at the time specified in the Time of Day parameter.
· NOT_USED—When this option is chosen, the tool does not use a Time of Day
when calculating the closest facilities. Live and historical traffic data will
not be used.
Time Zone
for Time of Day (optional)
Specifies the time zone of the Time of Day parameter.
· GEO_LOCAL—The Time of Day parameter refers to the time zone in which the
facilities or incidents are located.
o If Time of Day Usage is set to Start time and Travel Direction is
Facilities to Incidents, this is the time zone of the facilities.
o If Time of Day Usage is set to Start time and Travel Direction is
Incidents to Facilities, this is the time zone of the incidents.
o If Time of Day Usage is set to End time and Travel Direction is Facilities
to Incidents, this is the time zone of the incidents.
o If Time of Day Usage is set to End time and Travel Direction is Incidents
to Facilities, this is the time zone of the facilities.
· UTC—The Time of Day parameter refers to Coordinated Universal Time (UTC).
Choose this option if you want to find what's nearest for a specific time, such
as now, but aren't certain in which time zone the facilities or incidents will
be located.
Irrespective of the Time Zone for Time of Day setting, if your facilities
and incidents are in multiple time zones, the following rules are enforced by
the tool:
· All incidents must be in the same time zone for the following:
o Specifying a start time and traveling from incident to facility.
o Specifying an end time and traveling from facility to incident.
· All facilities must be in the same time zone for the following:
o Specifying a start time and traveling from facility to incident.
o Specifying an end time and traveling from incident to facility.
Overrides
(optional)
Specify additional settings that can influence the behavior of the solver
when finding solutions for the network analysis problems.
The value for this parameter needs to be specified in JavaScript Object
Notation (JSON). For example, a valid value is of the following form
{"overrideSetting1" : "value1",
"overrideSetting2" : "value2"}. The override setting name
is always enclosed in double quotation marks. The values can be either a
number, Boolean, or a string.
The default value for this parameter is no value, which indicates not to
override any solver settings.
Overrides are advanced settings that should be used only after careful
analysis of the results obtained before and after applying the settings. A list
of supported override settings for each solver and their acceptable values can
be obtained by contacting Esri Technical Support.
Point
Barriers (optional)
Specifies point barriers, which are split into two types: restriction and
added cost point barriers. They temporarily restrict traversal across or add
impedance to points on the network. The point barriers are defined by a feature
set, and the attribute values you specify for the point features determine
whether they are restriction or added cost barriers. The fields in the
attribute table are listed and described below.
ObjectID:
The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
BarrierType:
Specifies whether the barrier restricts travel completely or adds cost
when traveling through it. There are two options:
· Restriction (0)—Prohibits traversing through the barrier. This is the
default value.
· Added Cost (2)—Traversing through the barrier increases the network cost
by the amount specified in the Additional_Time and Additional_Distance fields.
Use the value 0 for Restriction and 2 for Added Cost.
Additional_Time:
Indicates how much travel time is added when the barrier is traversed.
This field is applicable only for added-cost barriers and only if the
measurement units are time based. This field value must be greater than or
equal to zero, and its units are the same as those specified in the measurement
units parameter.
Additional_Distance:
Indicates how much distance is added when the barrier is traversed. This
field is applicable only for added-cost barriers and only if the measurement
units are distance based. The field value must be greater than or equal to
zero, and its units are the same as those specified in the measurement units
parameter.
Line
Barriers (optional)
Specifies line barriers, which temporarily restrict traversal across them.
The line barriers are defined by a feature set. The fields in the attribute table
are listed and described below.
ObjectID:
The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
Polygon
Barriers (optional)
Specifies polygon barriers, which are split into two types: restriction
and scaled cost polygon barriers. They temporarily restrict traversal or scale
impedance on the parts of the network they cover. The polygon barriers are
defined by a feature set, and the attribute values you specify for the polygon
features determine whether they are restriction or scaled cost barriers. The
fields in the attribute table are listed and described below.
ObjectID:
The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
BarrierType:
Specifies whether the barrier restricts travel completely or scales the
cost of traveling through it. There are two options:
· Restriction (0)—Prohibits traversing through any part of the barrier. This
is the default value.
· Scaled Cost (1)—Scales the impedance of underlying edges by multiplying
them by the value of the ScaledCostFactor property. If edges are partially
covered by the barrier, the impedance is apportioned and multiplied.
Use the value 0 for Restriction and 1 for Scaled Cost.
ScaledTimeFactor:
This is the factor by which the travel time of the streets intersected by
the barrier is multiplied. This field is applicable only for scaled-cost
barriers and only if the measurement units are time based. The field value must
be greater than zero.
ScaledDistanceFactor:
This is the factor by which the distance of the streets intersected by the
barrier is multiplied. This attribute is applicable only for scaled-cost
barriers and only if the measurement units are distance based. The attribute
value must be greater than zero.
UTurn
Policy (optional)
The U-Turn policy at junctions. Allowing U-turns implies the solver can
turn around at a junction and double back on the same street. Given that
junctions represent street intersections and dead ends, different vehicles may
be able to turn around at some junctions but not at others—it depends on
whether the junction represents an intersection or dead end. To accommodate, the
U-turn policy parameter is implicitly specified by how many edges connect to
the junction, which is known as junction valency. The acceptable values for
this parameter are listed below; each is followed by a description of its
meaning in terms of junction valency.
· ALLOW_UTURNS—U-turns are permitted at junctions with any number of
connected edges. This is the default value.
· NO_UTURNS—U-turns are prohibited at all junctions, regardless of junction
valency. Note, however, that U-turns are still permitted at network locations
even when this setting is chosen; however, you can set the individual network
locations' CurbApproach property to prohibit U-turns there as well.
· ALLOW_DEAD_ENDS_ONLY—U-turns are prohibited at all junctions, except those
that have only one adjacent edge (a dead end).
· ALLOW_DEAD_ENDS_AND_INTERSECTIONS_ONLY—U-turns are prohibited at junctions
where exactly two adjacent edges meet but are permitted at intersections
(junctions with three or more adjacent edges) and dead ends (junctions with
exactly one adjacent edge). Often, networks have extraneous junctions in the
middle of road segments. This option prevents vehicles from making U-turns at
these locations.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
If you need a more precisely defined U-turn policy, consider adding a
global turn delay evaluator to a network cost attribute, or adjusting its
settings if one exists, and pay particular attention to the configuration of
reverse turns. Also, look at setting the CurbApproach property of your network
locations.
Time
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a time unit.
The tool performs the necessary time-unit conversion when the measurement
units value differs from the units of the cost attribute defined here. In other
words, the time units of the default cutoff and the network cost attribute
don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Time
Attribute Units (optional)
The units of the network cost attribute specified by the Time Attribute
parameter. This is merely an informational parameter that cannot be changed
without directly editing the network dataset. It is also unnecessary to change
since the unit conversions between measurement units and the cost attribute are
handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Distance
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a distance unit.
The tool performs the necessary distance-unit conversion when the
measurement units value differs from the units of the cost attribute defined
here. In other words, the measurement units and the distance units of the
network cost attribute don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Distance
Attribute Units (optional)
The units of the network cost attribute specified by the Distance
Attribute parameter. This is merely an informational parameter that cannot be
changed without directly editing the network dataset. It is also unnecessary to
change since the unit conversions between measurement units and the cost
attribute are handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Use
Hierarchy in Analysis (optional)
Specify whether hierarchy should be used when finding the shortest routes
between points.
· Checked (True) - Use hierarchy when finding routes. When hierarchy is
used, the tool prefers higher-order streets (such as freeways) to lower-order
streets (such as local roads) and can be used to simulate the driver preference
of traveling on freeways instead of local roads even if that means a longer
trip. This is especially true when finding routes to faraway facilities,
because drivers on long-distance trips tend to prefer traveling on freeways
where stops, intersections, and turns can be avoided. Using hierarchy is
computationally faster, especially for long-distance routes, because the tool
has to select the best route from a relatively smaller subset of streets. This
is the default value.
· Unchecked (False) - Do not use hierarchy when finding routes. If hierarchy
is not used, the tool considers all the streets and doesn't prefer higher-order
streets when finding the route. This is often used when finding short-distance
routes within a city.
The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This
improves the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These
accumulation attributes are purely for reference; the solver only uses the cost
attribute specified by the Time Attribute (Time_Attribute in Python) or
Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This
parameter is used only when the Populate Directions parameter is checked, or
set to True. The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Polygon Barriers (optional)
Limits how many features can be affected by polygon barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities (optional)
Limits how many facilities can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.
2.
Time of Day (optional) الوقت من
اليوم (اختياري)
Specifies the time and
date at which the routes should begin or end. The value is used as the start
time or end time for the route depending on the value for the Time of Day Usage
parameter. If you specify the current date and time as the value for this
parameter, the tool will use live traffic conditions to find the closest
facilities and the total travel time will be based on traffic conditions.
يحدد الوقت والتاريخ اللذين يجب أن تبدأ فيهما
المسارات أو تنتهي عندهما. يتم استخدام القيمة كوقت البدء أو وقت الانتهاء للمسار
بناءً على قيمة معلمة استخدام وقت اليوم. إذا حددت التاريخ والوقت الحاليين كقيمة
لهذه المعلمة ، فستستخدم الأداة ظروف حركة المرور الحية للعثور على أقرب المرافق
وسيعتمد إجمالي وقت السفر على ظروف حركة المرور.
إذا كانت مجموعة بيانات الشبكة الخاصة بك تحتوي
على بيانات حركة مرور حية أو تاريخية ، فإن تحديد وقت من اليوم ينتج عنه تقدير
أكثر دقة لوقت السفر بين الحادث والمنشأة لأن أوقات السفر تحسب ظروف حركة المرور
المطبقة لذلك التاريخ والوقت.
تحدد معلمة المنطقة الزمنية للوقت من اليوم ما إذا
كان هذا الوقت والتاريخ يشيران إلى التوقيت العالمي المنسق أو المنطقة الزمنية
التي تقع فيها المنشأة أو الواقعة.
بصرف النظر عن إعداد المنطقة الزمنية للوقت من اليوم
، إذا كانت منشآتك وأحداثك في مناطق زمنية متعددة ، يتم فرض القواعد التالية
بواسطة الأداة:
• يجب أن تكون جميع
الحوادث في نفس المنطقة الزمنية لما يلي:
o تحديد
وقت البدء والانتقال من حادث إلى آخر.
o تحديد
وقت الانتهاء والانتقال من منشأة إلى أخرى.
• يجب أن تكون جميع
المرافق في نفس المنطقة الزمنية لما يلي:
o تحديد
وقت البدء والانتقال من منشأة إلى أخرى.
o تحديد
وقت الانتهاء والانتقال من حادث إلى آخر.
3.
Time of Day Usage (optional) وقت
الاستخدام (اختياري)
Indicates whether the
Time of Day parameter value represents the arrival or departure time for the
routes.
يشير إلى ما إذا كانت قيمة معلمة "الوقت من

• START_TIME - عند تحديد هذا الخيار ، تعثر الأداة على أفضل مسار مع الأخذ في
الاعتبار قيمة معلمة "الوقت من اليوم" كوقت المغادرة من المنشأة أو
الحادث.
• END_TIME - عند تحديد هذا الخيار ، تأخذ الأداة في الاعتبار قيمة معلمة
"الوقت من اليوم" على أنها وقت الوصول إلى المنشأة أو الحادث. يكون هذا
الخيار مفيدًا إذا كنت تريد معرفة وقت المغادرة من موقع حتى تصل إلى الوجهة في
الوقت المحدد في معلمة الوقت من اليوم.
• NOT_USED - عند تحديد هذا الخيار ، لا تستخدم الأداة وقتًا من اليوم عند
حساب أقرب المرافق. لن يتم استخدام بيانات حركة المرور الحية والتاريخية.
Time Zone
for Time of Day (optional)
Specifies the time zone of the Time of Day parameter.
· GEO_LOCAL—The Time of Day parameter refers to the time zone in which the
facilities or incidents are located.
o If Time of Day Usage is set to Start time and Travel Direction is
Facilities to Incidents, this is the time zone of the facilities.
o If Time of Day Usage is set to Start time and Travel Direction is
Incidents to Facilities, this is the time zone of the incidents.
o If Time of Day Usage is set to End time and Travel Direction is Facilities
to Incidents, this is the time zone of the incidents.
o If Time of Day Usage is set to End time and Travel Direction is Incidents
to Facilities, this is the time zone of the facilities.
· UTC—The Time of Day parameter refers to Coordinated Universal Time (UTC).
Choose this option if you want to find what's nearest for a specific time, such
as now, but aren't certain in which time zone the facilities or incidents will
be located.
Irrespective of the Time Zone for Time of Day setting, if your facilities
and incidents are in multiple time zones, the following rules are enforced by
the tool:
· All incidents must be in the same time zone for the following:
o Specifying a start time and traveling from incident to facility.
o Specifying an end time and traveling from facility to incident.
· All facilities must be in the same time zone for the following:
o Specifying a start time and traveling from facility to incident.
o Specifying an end time and traveling from incident to facility.
Overrides
(optional)
Specify additional settings that can influence the behavior of the solver
when finding solutions for the network analysis problems.
The value for this parameter needs to be specified in JavaScript Object
Notation (JSON). For example, a valid value is of the following form
{"overrideSetting1" : "value1",
"overrideSetting2" : "value2"}. The override setting name
is always enclosed in double quotation marks. The values can be either a number,
Boolean, or a string.
The default value for this parameter is no value, which indicates not to
override any solver settings.
Overrides are advanced settings that should be used only after careful
analysis of the results obtained before and after applying the settings. A list
of supported override settings for each solver and their acceptable values can
be obtained by contacting Esri Technical Support.

impedance on the parts of the network they cover. The polygon barriers are
defined by a feature set, and the attribute values you specify for the polygon
features determine whether they are restriction or scaled cost barriers. The
fields in the attribute table are listed and described below.

The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
BarrierType:
Specifies whether the barrier restricts travel completely or scales the
cost of traveling through it. There are two options:
· Restriction (0)—Prohibits traversing through any part of the barrier. This
is the default value.
· Scaled Cost (1)—Scales the impedance of underlying edges by multiplying
them by the value of the ScaledCostFactor property. If edges are partially
covered by the barrier, the impedance is apportioned and multiplied.
Use the value 0 for Restriction and 1 for Scaled Cost.
ScaledTimeFactor:
This is the factor by which the travel time of the streets intersected by
the barrier is multiplied. This field is applicable only for scaled-cost
barriers and only if the measurement units are time based. The field value must
be greater than zero.
ScaledDistanceFactor:
This is the factor by which the distance of the streets intersected by the
barrier is multiplied. This attribute is applicable only for scaled-cost
barriers and only if the measurement units are distance based. The attribute
value must be greater than zero.
UTurn
Policy (optional)
The U-Turn policy at junctions. Allowing U-turns implies the solver can
turn around at a junction and double back on the same street. Given that
junctions represent street intersections and dead ends, different vehicles may
be able to turn around at some junctions but not at others—it depends on
whether the junction represents an intersection or dead end. To accommodate,
the U-turn policy parameter is implicitly specified by how many edges connect
to the junction, which is known as junction valency. The acceptable values for
this parameter are listed below; each is followed by a description of its
meaning in terms of junction valency.
· ALLOW_UTURNS—U-turns are permitted at junctions with any number of
connected edges. This is the default value.
· NO_UTURNS—U-turns are prohibited at all junctions, regardless of junction
valency. Note, however, that U-turns are still permitted at network locations
even when this setting is chosen; however, you can set the individual network
locations' CurbApproach property to prohibit U-turns there as well.
· ALLOW_DEAD_ENDS_ONLY—U-turns are prohibited at all junctions, except those
that have only one adjacent edge (a dead end).
· ALLOW_DEAD_ENDS_AND_INTERSECTIONS_ONLY—U-turns are prohibited at junctions
where exactly two adjacent edges meet but are permitted at intersections
(junctions with three or more adjacent edges) and dead ends (junctions with
exactly one adjacent edge). Often, networks have extraneous junctions in the
middle of road segments. This option prevents vehicles from making U-turns at
these locations.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
If you need a more precisely defined U-turn policy, consider adding a
global turn delay evaluator to a network cost attribute, or adjusting its
settings if one exists, and pay particular attention to the configuration of
reverse turns. Also, look at setting the CurbApproach property of your network
locations.
Time
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a time unit.
The tool performs the necessary time-unit conversion when the measurement
units value differs from the units of the cost attribute defined here. In other
words, the time units of the default cutoff and the network cost attribute
don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Time
Attribute Units (optional)
The units of the network cost attribute specified by the Time Attribute
parameter. This is merely an informational parameter that cannot be changed
without directly editing the network dataset. It is also unnecessary to change
since the unit conversions between measurement units and the cost attribute are
handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Distance
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a distance unit.
The tool performs the necessary distance-unit conversion when the
measurement units value differs from the units of the cost attribute defined
here. In other words, the measurement units and the distance units of the
network cost attribute don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Distance
Attribute Units (optional)
The units of the network cost attribute specified by the Distance
Attribute parameter. This is merely an informational parameter that cannot be
changed without directly editing the network dataset. It is also unnecessary to
change since the unit conversions between measurement units and the cost
attribute are handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Use
Hierarchy in Analysis (optional)
Specify whether hierarchy should be used when finding the shortest routes
between points.
· Checked (True) - Use hierarchy when finding routes. When hierarchy is
used, the tool prefers higher-order streets (such as freeways) to lower-order
streets (such as local roads) and can be used to simulate the driver preference
of traveling on freeways instead of local roads even if that means a longer
trip. This is especially true when finding routes to faraway facilities,
because drivers on long-distance trips tend to prefer traveling on freeways where
stops, intersections, and turns can be avoided. Using hierarchy is
computationally faster, especially for long-distance routes, because the tool
has to select the best route from a relatively smaller subset of streets. This
is the default value.
· Unchecked (False) - Do not use hierarchy when finding routes. If hierarchy
is not used, the tool considers all the streets and doesn't prefer higher-order
streets when finding the route. This is often used when finding short-distance
routes within a city.
The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This improves
the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These accumulation
attributes are purely for reference; the solver only uses the cost attribute
specified by the Time Attribute (Time_Attribute in Python) or Distance
Attribute (Distance_Attribute in Python) parameter to calculate the shortest
paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This parameter
is used only when the Populate Directions parameter is checked, or set to True.
The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Polygon Barriers (optional)
Limits how many features can be affected by polygon barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities (optional)
Limits how many facilities can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.
4.

Specifies the time zone
of the Time of Day parameter.

Point
Barriers (optional)
Specifies point barriers, which are split into two types: restriction and
added cost point barriers. They temporarily restrict traversal across or add
impedance to points on the network. The point barriers are defined by a feature
set, and the attribute values you specify for the point features determine
whether they are restriction or added cost barriers. The fields in the
attribute table are listed and described below.
ObjectID:
The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
BarrierType:
Specifies whether the barrier restricts travel completely or adds cost
when traveling through it. There are two options:
· Restriction (0)—Prohibits traversing through the barrier. This is the
default value.
· Added Cost (2)—Traversing through the barrier increases the network cost
by the amount specified in the Additional_Time and Additional_Distance fields.
Use the value 0 for Restriction and 2 for Added Cost.
Additional_Time:
Indicates how much travel time is added when the barrier is traversed.
This field is applicable only for added-cost barriers and only if the
measurement units are time based. This field value must be greater than or
equal to zero, and its units are the same as those specified in the measurement
units parameter.
Additional_Distance:
Indicates how much distance is added when the barrier is traversed. This
field is applicable only for added-cost barriers and only if the measurement
units are distance based. The field value must be greater than or equal to
zero, and its units are the same as those specified in the measurement units
parameter.
Line
Barriers (optional)
Specifies line barriers, which temporarily restrict traversal across them.
The line barriers are defined by a feature set. The fields in the attribute
table are listed and described below.
ObjectID:
The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
Polygon
Barriers (optional)
Specifies polygon barriers, which are split into two types: restriction
and scaled cost polygon barriers. They temporarily restrict traversal or scale
impedance on the parts of the network they cover. The polygon barriers are
defined by a feature set, and the attribute values you specify for the polygon
features determine whether they are restriction or scaled cost barriers. The
fields in the attribute table are listed and described below.
ObjectID:
The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
BarrierType:
Specifies whether the barrier restricts travel completely or scales the
cost of traveling through it. There are two options:
· Restriction (0)—Prohibits traversing through any part of the barrier. This
is the default value.
· Scaled Cost (1)—Scales the impedance of underlying edges by multiplying
them by the value of the ScaledCostFactor property. If edges are partially
covered by the barrier, the impedance is apportioned and multiplied.
Use the value 0 for Restriction and 1 for Scaled Cost.
ScaledTimeFactor:
This is the factor by which the travel time of the streets intersected by
the barrier is multiplied. This field is applicable only for scaled-cost
barriers and only if the measurement units are time based. The field value must
be greater than zero.
ScaledDistanceFactor:
This is the factor by which the distance of the streets intersected by the
barrier is multiplied. This attribute is applicable only for scaled-cost
barriers and only if the measurement units are distance based. The attribute
value must be greater than zero.
UTurn Policy
(optional)
The U-Turn policy at junctions. Allowing U-turns implies the solver can
turn around at a junction and double back on the same street. Given that
junctions represent street intersections and dead ends, different vehicles may
be able to turn around at some junctions but not at others—it depends on
whether the junction represents an intersection or dead end. To accommodate,
the U-turn policy parameter is implicitly specified by how many edges connect
to the junction, which is known as junction valency. The acceptable values for
this parameter are listed below; each is followed by a description of its
meaning in terms of junction valency.
· ALLOW_UTURNS—U-turns are permitted at junctions with any number of
connected edges. This is the default value.
· NO_UTURNS—U-turns are prohibited at all junctions, regardless of junction
valency. Note, however, that U-turns are still permitted at network locations
even when this setting is chosen; however, you can set the individual network
locations' CurbApproach property to prohibit U-turns there as well.
· ALLOW_DEAD_ENDS_ONLY—U-turns are prohibited at all junctions, except those
that have only one adjacent edge (a dead end).
· ALLOW_DEAD_ENDS_AND_INTERSECTIONS_ONLY—U-turns are prohibited at junctions
where exactly two adjacent edges meet but are permitted at intersections
(junctions with three or more adjacent edges) and dead ends (junctions with
exactly one adjacent edge). Often, networks have extraneous junctions in the
middle of road segments. This option prevents vehicles from making U-turns at
these locations.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
If you need a more precisely defined U-turn policy, consider adding a
global turn delay evaluator to a network cost attribute, or adjusting its
settings if one exists, and pay particular attention to the configuration of
reverse turns. Also, look at setting the CurbApproach property of your network
locations.
Time
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a time unit.
The tool performs the necessary time-unit conversion when the measurement
units value differs from the units of the cost attribute defined here. In other
words, the time units of the default cutoff and the network cost attribute
don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Time
Attribute Units (optional)
The units of the network cost attribute specified by the Time Attribute
parameter. This is merely an informational parameter that cannot be changed
without directly editing the network dataset. It is also unnecessary to change
since the unit conversions between measurement units and the cost attribute are
handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Distance
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a distance unit.
The tool performs the necessary distance-unit conversion when the
measurement units value differs from the units of the cost attribute defined
here. In other words, the measurement units and the distance units of the
network cost attribute don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Distance
Attribute Units (optional)
The units of the network cost attribute specified by the Distance
Attribute parameter. This is merely an informational parameter that cannot be
changed without directly editing the network dataset. It is also unnecessary to
change since the unit conversions between measurement units and the cost
attribute are handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Use
Hierarchy in Analysis (optional)
Specify whether hierarchy should be used when finding the shortest routes
between points.
· Checked (True) - Use hierarchy when finding routes. When hierarchy is
used, the tool prefers higher-order streets (such as freeways) to lower-order
streets (such as local roads) and can be used to simulate the driver preference
of traveling on freeways instead of local roads even if that means a longer
trip. This is especially true when finding routes to faraway facilities,
because drivers on long-distance trips tend to prefer traveling on freeways
where stops, intersections, and turns can be avoided. Using hierarchy is
computationally faster, especially for long-distance routes, because the tool
has to select the best route from a relatively smaller subset of streets. This
is the default value.
· Unchecked (False) - Do not use hierarchy when finding routes. If hierarchy
is not used, the tool considers all the streets and doesn't prefer higher-order
streets when finding the route. This is often used when finding short-distance
routes within a city.
The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This
improves the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These
accumulation attributes are purely for reference; the solver only uses the cost
attribute specified by the Time Attribute (Time_Attribute in Python) or
Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language, Directions
Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This
parameter is used only when the Populate Directions parameter is checked, or
set to True. The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Polygon Barriers (optional)
Limits how many features can be affected by polygon barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities (optional)
Limits how many facilities can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest facilities
without using the hierarchy. This parameter helps you govern the amount of
processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.
6.
Point Barriers (optional) حواجز
النقاط (اختياري)
Specifies point barriers,
which are split into two types: restriction and added cost point barriers. They
temporarily restrict traversal across or add impedance to points on the
network. The point barriers are defined by a feature set, and the attribute
values you specify for the point features determine whether they are
restriction or added cost barriers. The fields in the attribute table are
listed and described below.

تحليل الشبكة.
اسم:
اسم الحاجز.
النوع:
يحدد ما إذا كان الحاجز يقيد السفر تمامًا أو يضيف
تكلفة عند السفر عبره. هناك خياران:
• تقييد (0) - يحظر عبور
الحاجز. هذه هي القيمة الافتراضية.
• التكلفة المضافة (2) -
يؤدي عبور الحاجز إلى زيادة تكلفة الشبكة بالمبلغ المحدد في حقلي الوقت الإضافي
وحقول المسافة الإضافية.
استخدم القيمة 0 للتقييد و 2 للتكلفة المضافة.

يشير إلى مقدار المسافة التي يتم إضافتها عند
اجتياز الحاجز. ينطبق هذا المجال فقط على حواجز التكلفة المضافة وفقط إذا كانت
وحدات القياس تعتمد على المسافة. يجب أن تكون قيمة الحقل أكبر من أو تساوي الصفر ،
وأن تكون وحداته مماثلة لتلك المحددة في معلمة وحدات القياس.
Line
Barriers (optional)
Specifies line barriers, which temporarily restrict traversal across them.
The line barriers are defined by a feature set. The fields in the attribute
table are listed and described below.
ObjectID:
The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
Polygon
Barriers (optional)
Specifies polygon barriers, which are split into two types: restriction
and scaled cost polygon barriers. They temporarily restrict traversal or scale
impedance on the parts of the network they cover. The polygon barriers are
defined by a feature set, and the attribute values you specify for the polygon
features determine whether they are restriction or scaled cost barriers. The
fields in the attribute table are listed and described below.
ObjectID:
The system-managed ID field.
Shape:
The geometry field indicating the geographic location of the network
analysis object.
Name:
The name of the barrier.
BarrierType:
Specifies whether the barrier restricts travel completely or scales the
cost of traveling through it. There are two options:
· Restriction (0)—Prohibits traversing through any part of the barrier. This
is the default value.
· Scaled Cost (1)—Scales the impedance of underlying edges by multiplying
them by the value of the ScaledCostFactor property. If edges are partially
covered by the barrier, the impedance is apportioned and multiplied.
Use the value 0 for Restriction and 1 for Scaled Cost.
ScaledTimeFactor:
This is the factor by which the travel time of the streets intersected by
the barrier is multiplied. This field is applicable only for scaled-cost
barriers and only if the measurement units are time based. The field value must
be greater than zero.
ScaledDistanceFactor:
This is the factor by which the distance of the streets intersected by the
barrier is multiplied. This attribute is applicable only for scaled-cost
barriers and only if the measurement units are distance based. The attribute
value must be greater than zero.
UTurn
Policy (optional)
The U-Turn policy at junctions. Allowing U-turns implies the solver can
turn around at a junction and double back on the same street. Given that
junctions represent street intersections and dead ends, different vehicles may
be able to turn around at some junctions but not at others—it depends on
whether the junction represents an intersection or dead end. To accommodate,
the U-turn policy parameter is implicitly specified by how many edges connect
to the junction, which is known as junction valency. The acceptable values for
this parameter are listed below; each is followed by a description of its
meaning in terms of junction valency.
· ALLOW_UTURNS—U-turns are permitted at junctions with any number of
connected edges. This is the default value.
· NO_UTURNS—U-turns are prohibited at all junctions, regardless of junction
valency. Note, however, that U-turns are still permitted at network locations
even when this setting is chosen; however, you can set the individual network
locations' CurbApproach property to prohibit U-turns there as well.
· ALLOW_DEAD_ENDS_ONLY—U-turns are prohibited at all junctions, except those
that have only one adjacent edge (a dead end).
· ALLOW_DEAD_ENDS_AND_INTERSECTIONS_ONLY—U-turns are prohibited at junctions
where exactly two adjacent edges meet but are permitted at intersections
(junctions with three or more adjacent edges) and dead ends (junctions with
exactly one adjacent edge). Often, networks have extraneous junctions in the
middle of road segments. This option prevents vehicles from making U-turns at
these locations.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
If you need a more precisely defined U-turn policy, consider adding a
global turn delay evaluator to a network cost attribute, or adjusting its
settings if one exists, and pay particular attention to the configuration of
reverse turns. Also, look at setting the CurbApproach property of your network
locations.
Time
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a time unit.
The tool performs the necessary time-unit conversion when the measurement
units value differs from the units of the cost attribute defined here. In other
words, the time units of the default cutoff and the network cost attribute
don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Time
Attribute Units (optional)
The units of the network cost attribute specified by the Time Attribute
parameter. This is merely an informational parameter that cannot be changed
without directly editing the network dataset. It is also unnecessary to change
since the unit conversions between measurement units and the cost attribute are
handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Distance
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a distance unit.
The tool performs the necessary distance-unit conversion when the
measurement units value differs from the units of the cost attribute defined
here. In other words, the measurement units and the distance units of the
network cost attribute don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Distance
Attribute Units (optional)
The units of the network cost attribute specified by the Distance
Attribute parameter. This is merely an informational parameter that cannot be
changed without directly editing the network dataset. It is also unnecessary to
change since the unit conversions between measurement units and the cost
attribute are handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Use
Hierarchy in Analysis (optional)
Specify whether hierarchy should be used when finding the shortest routes
between points.
· Checked (True) - Use hierarchy when finding routes. When hierarchy is
used, the tool prefers higher-order streets (such as freeways) to lower-order
streets (such as local roads) and can be used to simulate the driver preference
of traveling on freeways instead of local roads even if that means a longer
trip. This is especially true when finding routes to faraway facilities,
because drivers on long-distance trips tend to prefer traveling on freeways
where stops, intersections, and turns can be avoided. Using hierarchy is
computationally faster, especially for long-distance routes, because the tool
has to select the best route from a relatively smaller subset of streets. This
is the default value.
· Unchecked (False) - Do not use hierarchy when finding routes. If hierarchy
is not used, the tool considers all the streets and doesn't prefer higher-order
streets when finding the route. This is often used when finding short-distance
routes within a city.
The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This
improves the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These
accumulation attributes are purely for reference; the solver only uses the cost
attribute specified by the Time Attribute (Time_Attribute in Python) or
Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This
parameter is used only when the Populate Directions parameter is checked, or
set to True. The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are returned.
However, a server administrator may want to choose to output a network analysis
layer as well so that the setup and results of the tool can be debugged using
the Network Analyst controls in the ArcGIS Desktop environment. This can make
the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.

version of the service.
A null value indicates there is no limit.
Maximum
Facilities (optional)
Limits how many facilities can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free

paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when

paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.

them by the value of the ScaledCostFactor property. If edges are partially
covered by the barrier, the impedance is apportioned and multiplied.
Use the value 0 for Restriction and 1 for Scaled Cost.
ScaledTimeFactor:
This is the factor by which the travel time of the streets intersected by
the barrier is multiplied. This field is applicable only for scaled-cost
barriers and only if the measurement units are time based. The field value must
be greater than zero.
ScaledDistanceFactor:
This is the factor by which the distance of the streets intersected by the

Time
Attribute (optional)
Defines the network cost attribute to use when the measurement units value

The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This
improves the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These
accumulation attributes are purely for reference; the solver only uses the cost
attribute specified by the Time Attribute (Time_Attribute in Python) or
Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This
parameter is used only when the Populate Directions parameter is checked, or
set to True. The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Polygon Barriers (optional)
Limits how many features can be affected by polygon barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities (optional)
Limits how many facilities can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.
8.
Polygon Barriers (optional) حواجز
مضلعة (اختياري)
Specifies polygon
barriers, which are split into two types: restriction and scaled cost polygon
barriers. They temporarily restrict traversal or scale impedance on the parts
of the network they cover. The polygon barriers are defined by a feature set,
and the attribute values you specify for the polygon features determine whether
they are restriction or scaled cost barriers. The fields in the attribute table
are listed and described below.
ObjectID:

ومضاعفتها.
استخدم القيمة 0 للتقييد و 1 للتكلفة المقاسة.

الشوارع التي يتقاطع معها الحاجز. هذه السمة قابلة للتطبيق فقط على حواجز التكلفة
المتدرجة وفقط إذا كانت وحدات القياس تعتمد على المسافة. يجب أن تكون قيمة السمة
أكبر من الصفر.
UTurn
Policy (optional)
The U-Turn policy at junctions. Allowing U-turns implies the solver can
turn around at a junction and double back on the same street. Given that
junctions represent street intersections and dead ends, different vehicles may
be able to turn around at some junctions but not at others—it depends on
whether the junction represents an intersection or dead end. To accommodate,
the U-turn policy parameter is implicitly specified by how many edges connect
to the junction, which is known as junction valency. The acceptable values for
this parameter are listed below; each is followed by a description of its
meaning in terms of junction valency.
· ALLOW_UTURNS—U-turns are permitted at junctions with any number of
connected edges. This is the default value.
· NO_UTURNS—U-turns are prohibited at all junctions, regardless of junction
valency. Note, however, that U-turns are still permitted at network locations
even when this setting is chosen; however, you can set the individual network
locations' CurbApproach property to prohibit U-turns there as well.
· ALLOW_DEAD_ENDS_ONLY—U-turns are prohibited at all junctions, except those
that have only one adjacent edge (a dead end).
· ALLOW_DEAD_ENDS_AND_INTERSECTIONS_ONLY—U-turns are prohibited at junctions
where exactly two adjacent edges meet but are permitted at intersections
(junctions with three or more adjacent edges) and dead ends (junctions with
exactly one adjacent edge). Often, networks have extraneous junctions in the
middle of road segments. This option prevents vehicles from making U-turns at
these locations.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
If you need a more precisely defined U-turn policy, consider adding a
global turn delay evaluator to a network cost attribute, or adjusting its
settings if one exists, and pay particular attention to the configuration of
reverse turns. Also, look at setting the CurbApproach property of your network
locations.
Time
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a time unit.
The tool performs the necessary time-unit conversion when the measurement
units value differs from the units of the cost attribute defined here. In other
words, the time units of the default cutoff and the network cost attribute
don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Time
Attribute Units (optional)
The units of the network cost attribute specified by the Time Attribute
parameter. This is merely an informational parameter that cannot be changed
without directly editing the network dataset. It is also unnecessary to change
since the unit conversions between measurement units and the cost attribute are
handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Distance Attribute
(optional)
Defines the network cost attribute to use when the measurement units value
is a distance unit.
The tool performs the necessary distance-unit conversion when the
measurement units value differs from the units of the cost attribute defined
here. In other words, the measurement units and the distance units of the
network cost attribute don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Distance
Attribute Units (optional)
The units of the network cost attribute specified by the Distance
Attribute parameter. This is merely an informational parameter that cannot be
changed without directly editing the network dataset. It is also unnecessary to
change since the unit conversions between measurement units and the cost
attribute are handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Use
Hierarchy in Analysis (optional)
Specify whether hierarchy should be used when finding the shortest routes
between points.
· Checked (True) - Use hierarchy when finding routes. When hierarchy is
used, the tool prefers higher-order streets (such as freeways) to lower-order
streets (such as local roads) and can be used to simulate the driver preference
of traveling on freeways instead of local roads even if that means a longer
trip. This is especially true when finding routes to faraway facilities,
because drivers on long-distance trips tend to prefer traveling on freeways
where stops, intersections, and turns can be avoided. Using hierarchy is
computationally faster, especially for long-distance routes, because the tool
has to select the best route from a relatively smaller subset of streets. This
is the default value.
· Unchecked (False) - Do not use hierarchy when finding routes. If hierarchy
is not used, the tool considers all the streets and doesn't prefer higher-order
streets when finding the route. This is often used when finding short-distance
routes within a city.
The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This
improves the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These
accumulation attributes are purely for reference; the solver only uses the cost
attribute specified by the Time Attribute (Time_Attribute in Python) or
Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language, Directions
Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This
parameter is used only when the Populate Directions parameter is checked, or
set to True. The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.

as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route

Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by

· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.

Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even

Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest

9.
UTurn Policy (optional) السياسة
(اختياري)
The U-Turn policy at
junctions. Allowing U-turns implies the solver can turn around at a junction
and double back on the same street. Given that junctions represent street
intersections and dead ends, different vehicles may be able to turn around at
some junctions but not at others—it depends on whether the junction represents
an intersection or dead end.
سياسة U-Turn عند
التقاطعات. يعني السماح بالدوران على شكل حرف U أن
المحلل يمكنه الالتفاف عند تقاطع طرق والعودة مرة أخرى في نفس الشارع. نظرًا لأن
التقاطعات تمثل تقاطعات الشوارع والطرق المسدودة ، فقد تتمكن المركبات المختلفة من
الالتفاف عند بعض التقاطعات ولكن ليس عند البعض الآخر - يعتمد ذلك على ما إذا كان
التقاطع يمثل تقاطعًا أو طريقًا مسدودًا.
للتوافق ، يتم تحديد معلمة نهج U-turn
ضمنيًا من خلال عدد الحواف المتصلة بالوصلة ، والتي تُعرف باسم تكافؤ الوصلة.
القيم المقبولة لهذه المعلمة مذكورة أدناه ؛ يتبع كل منها وصف لمعناها من حيث
تكافؤ الوصلات.
• ALLOW_UTURNS - يُسمح بالدوران على شكل حرف U عند
التقاطعات مع أي عدد من الحواف المتصلة. هذه هي القيمة الافتراضية.
• NO_UTURNS - يحظر الدوران U في
جميع التقاطعات ، بغض النظر عن تكافؤ الوصلات. لاحظ ، مع ذلك ، أن المنعطفات U لا
يزال مسموحًا بها في مواقع الشبكة حتى عند اختيار هذا الإعداد ؛ ومع ذلك ، يمكنك
تعيين خاصية CurbApproach لمواقع الشبكة الفردية
لحظر انعطاف U هناك أيضًا.
• ALLOW_DEAD_ENDS_ONLY - يُحظر الدوران للخلف في جميع التقاطعات ، باستثناء تلك التي
تحتوي على حافة مجاورة واحدة فقط (طريق مسدود).
• ALLOW_DEAD_ENDS_AND_INTERSECTIONS_ONLY - يُحظر استخدام
المنعطفات على شكل حرف U عند التقاطعات حيث تلتقي
حافتان متجاورتان تمامًا ولكن يُسمح بها عند التقاطعات (التقاطعات ذات ثلاثة حواف
متجاورة أو أكثر) والنهايات المسدودة (التقاطعات ذات حافة متجاورة واحدة بالضبط).
غالبًا ما تحتوي الشبكات على تقاطعات خارجية في منتصف أجزاء الطريق. يمنع هذا
الخيار المركبات من الدوران للخلف في هذه المواقع.
يتم تجاوز قيمة هذه المعلمة عند تعيين وضع السفر (Travel_Mode في Python) على أي قيمة بخلاف
القيمة المخصصة.
إذا كنت بحاجة إلى سياسة U-turn محددة
بشكل أكثر دقة ، ففكر في إضافة مقيِّم لتأخير الانعطاف العالمي إلى سمة تكلفة
الشبكة ، أو تعديل إعداداتها إن وجدت ، وإيلاء اهتمام خاص لتكوين المنعطفات
العكسية. انظر أيضًا إلى إعداد خاصية CurbApproach
لمواقع الشبكة الخاصة بك.

The tool performs the necessary distance-unit conversion when the
measurement units value differs from the units of the cost attribute defined
here. In other words, the measurement units and the distance units of the
network cost attribute don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Distance
Attribute Units (optional)
The units of the network cost attribute specified by the Distance
Attribute parameter. This is merely an informational parameter that cannot be
changed without directly editing the network dataset. It is also unnecessary to
change since the unit conversions between measurement units and the cost
attribute are handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Use
Hierarchy in Analysis (optional)
Specify whether hierarchy should be used when finding the shortest routes
between points.
· Checked (True) - Use hierarchy when finding routes. When hierarchy is
used, the tool prefers higher-order streets (such as freeways) to lower-order
streets (such as local roads) and can be used to simulate the driver preference
of traveling on freeways instead of local roads even if that means a longer
trip. This is especially true when finding routes to faraway facilities,
because drivers on long-distance trips tend to prefer traveling on freeways
where stops, intersections, and turns can be avoided. Using hierarchy is
computationally faster, especially for long-distance routes, because the tool
has to select the best route from a relatively smaller subset of streets. This
is the default value.
· Unchecked (False) - Do not use hierarchy when finding routes. If hierarchy
is not used, the tool considers all the streets and doesn't prefer higher-order
streets when finding the route. This is often used when finding short-distance
routes within a city.
The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This
improves the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These
accumulation attributes are purely for reference; the solver only uses the cost
attribute specified by the Time Attribute (Time_Attribute in Python) or
Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This
parameter is used only when the Populate Directions parameter is checked, or
set to True. The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Polygon Barriers (optional)
Limits how many features can be affected by polygon barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities (optional)
Limits how many facilities can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.
10.
Time Attribute (optional) جدول

Defines the network cost
attribute to use when the measurement units value is a time unit.

Time
Attribute Units (optional)
The units of the network cost attribute specified by the Time Attribute
parameter. This is merely an informational parameter that cannot be changed
without directly editing the network dataset. It is also unnecessary to change
since the unit conversions between measurement units and the cost attribute are
handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Distance
Attribute (optional)
Defines the network cost attribute to use when the measurement units value
is a distance unit.
The tool performs the necessary distance-unit conversion when the
measurement units value differs from the units of the cost attribute defined
here. In other words, the measurement units and the distance units of the
network cost attribute don't need to be the same.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than Custom.
Distance
Attribute Units (optional)
The units of the network cost attribute specified by the Distance
Attribute parameter. This is merely an informational parameter that cannot be
changed without directly editing the network dataset. It is also unnecessary to
change since the unit conversions between measurement units and the cost
attribute are handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Use
Hierarchy in Analysis (optional)
Specify whether hierarchy should be used when finding the shortest routes
between points.
· Checked (True) - Use hierarchy when finding routes. When hierarchy is used,
the tool prefers higher-order streets (such as freeways) to lower-order streets
(such as local roads) and can be used to simulate the driver preference of
traveling on freeways instead of local roads even if that means a longer trip.
This is especially true when finding routes to faraway facilities, because
drivers on long-distance trips tend to prefer traveling on freeways where
stops, intersections, and turns can be avoided. Using hierarchy is
computationally faster, especially for long-distance routes, because the tool
has to select the best route from a relatively smaller subset of streets. This
is the default value.
· Unchecked (False) - Do not use hierarchy when finding routes. If hierarchy
is not used, the tool considers all the streets and doesn't prefer higher-order
streets when finding the route. This is often used when finding short-distance
routes within a city.
The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This
improves the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These
accumulation attributes are purely for reference; the solver only uses the cost
attribute specified by the Time Attribute (Time_Attribute in Python) or
Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This
parameter is used only when the Populate Directions parameter is checked, or
set to True. The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free

A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free

A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.

Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.

The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is

based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.

· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free

A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.
12.
Distance Attribute (optional) جدول
بيانات المسافة (اختياري)
Defines the network cost
attribute to use when the measurement units value is a distance unit.
تحدد سمة تكلفة الشبكة لاستخدامها عندما تكون قيمة
وحدات القياس هي وحدة مسافة.
تقوم الأداة بإجراء التحويل الضروري لوحدة المسافة

يتم تجاوز قيمة هذه المعلمة عند تعيين Travel Mode (Travel_Mode في Python) على
أي قيمة بخلاف Custom.
Distance
Attribute Units (optional)
The units of the network cost attribute specified by the Distance
Attribute parameter. This is merely an informational parameter that cannot be
changed without directly editing the network dataset. It is also unnecessary to
change since the unit conversions between measurement units and the cost
attribute are handled for you.
The value of this parameter is overridden when Travel Mode is set to any
value other than Custom.
Use
Hierarchy in Analysis (optional)
Specify whether hierarchy should be used when finding the shortest routes
between points.
· Checked (True) - Use hierarchy when finding routes. When hierarchy is
used, the tool prefers higher-order streets (such as freeways) to lower-order
streets (such as local roads) and can be used to simulate the driver preference
of traveling on freeways instead of local roads even if that means a longer
trip. This is especially true when finding routes to faraway facilities,
because drivers on long-distance trips tend to prefer traveling on freeways
where stops, intersections, and turns can be avoided. Using hierarchy is
computationally faster, especially for long-distance routes, because the tool
has to select the best route from a relatively smaller subset of streets. This
is the default value.
· Unchecked (False) - Do not use hierarchy when finding routes. If hierarchy
is not used, the tool considers all the streets and doesn't prefer higher-order
streets when finding the route. This is often used when finding short-distance
routes within a city.
The parameter is disabled if a hierarchy attribute is not defined on the
network dataset used to perform the analysis.
You can use the Force Hierarchy Beyond Distance parameter to force the
solver to use hierarchy even if Use Hierarchy in Analysis is set to false.
This parameter is ignored unless Travel Mode is set to Custom. When
modeling a custom walking mode, it is recommended to turn off hierarchy since
the hierarchy is designed for motorized vehicles.
Restrictions
(optional)
Indicates which network restriction attributes are respected during solve
time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the table
row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This improves
the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These accumulation
attributes are purely for reference; the solver only uses the cost attribute
specified by the Time Attribute (Time_Attribute in Python) or Distance
Attribute (Distance_Attribute in Python) parameter to calculate the shortest
paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.

Attribute
Parameter Values (optional)
Specifies the parameter values for network attributes that have
parameters. The record set has two columns that work together to uniquely
identify parameters and another column that specifies the parameter value.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
The attribute parameter values record set has associated attributes. The
fields in the attribute table are listed below and described.
ObjectID:
The system-managed ID field.
AttributeName:
The name of the network attribute whose attribute parameter is set by the
table row.
ParameterName:
The name of the attribute parameter whose value is set by the table row.
(Object type parameters cannot be updated using this tool.)
ParameterValue:
The value you want for the attribute parameter. If a value is not
specified, the attribute parameter is set to null.
Route Line
Simplification Tolerance (optional)
Specify by how much you want to simplify the route geometry.
The tool ignores this parameter if the Route Shape parameter isn't set to
True lines with measures or True lines without measures.
Simplification maintains critical points on a route, such as turns at
intersections, to define the essential shape of the route and removes other
points. The simplification distance you specify is the maximum allowable offset
that the simplified line can deviate from the original line. Simplifying a line
reduces the number of vertices that are part of the route geometry. This
improves the tool execution time.
The value of this parameter is overridden when Travel Mode (Travel_Mode in
Python) is set to any value other than custom.
Accumulate
Attributes (optional)
List of cost attributes to be accumulated during analysis. These
accumulation attributes are purely for reference; the solver only uses the cost
attribute specified by the Time Attribute (Time_Attribute in Python) or
Distance Attribute (Distance_Attribute in Python) parameter to calculate the
shortest paths.
For each cost attribute that is accumulated, a Total_[attribute] field is
added to the routes that are output by the solver.
Maximum
Snap Tolerance (optional)
The maximum snap tolerance is the furthest distance that Network Analyst
searches when locating or relocating a point onto the network. The search looks
for suitable edges or junctions and snaps the point to the nearest one. If a
suitable location isn't found within the maximum snap tolerance, the object is
marked as unlocated.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.
· Unchecked (False):
Directions are not generated, and the
tool returns an empty Directions layer.
Directions
Language (optional)
Specify the language that should be used when generating driving
directions.
This parameter is used only when the Populate Directions parameter is
checked, or set to True.
The directions languages that are available depend on what ArcGIS language
packs you have installed on your computer. The values are entered in two- or
five-character language codes, for example, en for English or zh-CN for
simplified Chinese.
If an unsupported language code is specified, the tool returns the
directions using the default language, English.
Directions
Distance Units (optional)
Specify the units for displaying travel distance in the driving
directions. This parameter is used only when the Populate Directions parameter
is checked, or set to True.
· Miles
· Kilometers
· Meters
· Feet
· Yards
· NauticalMiles
Directions
Style Name (optional)
Specify the name of the formatting style for the directions. This
parameter is used only when the Populate Directions parameter is checked, or
set to True. The parameter can be specified using the following values:
· NA Desktop— Generates turn-by-turn directions suitable for printing.
· NA Navigation— Generates turn-by-turn directions designed for an
in-vehicle navigation device.
· NA Campus—Generates directions appropriate for pedestrian networks,
including sidewalks and building interiors.
Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free

paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Polygon Barriers (optional)
Limits how many features can be affected by polygon barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities (optional)
Limits how many facilities can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.

may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.
No matter which value you choose for the Route Shape parameter, the best
route is always determined by minimizing the travel time or the travel
distance, never using the straight-line distance between incidents and
facilities. This means that only the route shapes are different, not the
underlying streets that are searched when finding the route.
Populate
Directions (optional)
Specify whether the tool should generate driving directions for each
route.
· Checked (True):
Indicates that the directions will be
generated and configured based on the values for the Directions Language,
Directions Style Name, and Directions Distance Units parameters.

Save
Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis
layer is in the scratch folder. You can determine the location of the scratch
folder by evaluating the value of arcpy.env.scratchFolder geoprocessing
environment in the Python window. The output network analysis layer is stored
as an LYR file whose name begins with _ags_gpna and is followed by an
alphanumeric GUID.
Save Route
Data (optional)
Choose whether the output includes a zip file that contains a file
geodatabase holding the inputs and outputs of the analysis in a format that can
be used to share route layers with ArcGIS Online or Portal for ArcGIS.
In ArcGIS Desktop, the default output location for this output file is in
the scratch folder. You can determine the location of the scratch folder by
evaluating the value of the arcpy.env.scratchFolder geoprocessing environment.
· Checked (True): The tool writes out a .zip archive containing a file
geodatabase workspace that contains the inputs and outputs of the analysis.
· Unchecked (False): Route data is not saved. This is the default.
Maximum
Features Affected by Point Barriers (optional)
Limits how many features can be affected by point barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Features Affected by Line Barriers (optional)
Limits how many features can be affected by line barriers.
This parameter helps you govern the amount of processing that occurs when

This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Force Hierarchy
Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.
18.
Maximum Snap Tolerance (optional) الحد
الأقصى لتسامح المفاجئة (اختياري)
The maximum snap
tolerance is the furthest distance that Network Analyst searches when locating
or relocating a point onto the network. The search looks for suitable edges or
junctions and snaps the point to the nearest one. If a suitable location isn't found
within the maximum snap tolerance, the object is marked as unlocated.
الحد الأقصى للتسامح المفاجئ هو أبعد مسافة يبحث
عنها Network Analyst عند تحديد موقع نقطة أو
إعادة تحديد موقعها على الشبكة. يقوم البحث بالبحث عن الحواف أو التقاطعات
المناسبة ويقترب من النقطة الأقرب. إذا لم يتم العثور على موقع مناسب ضمن الحد
الأقصى لتفاوت الانجذاب ، يتم وضع علامة على الكائن على أنه غير محدد.
Feature
Locator WHERE Clause (optional)
An SQL expression used to select a subset of source features that limits
on which network elements facilities can be located. The syntax for this
parameter consists of two parts: the first is the source feature class name
(followed by a space) and the second is the SQL expression. To write an SQL
expression for two or more source feature classes, separate them with a
semicolon.
To ensure facilities are not located on limited-access highways, for
example, write an SQL expression like the following to exclude those source
features: "Streets" "FUNC_CLASS not in('1', '2')".
Note that barriers ignore the feature locator WHERE clause when loading.
Route
Shape (optional)
Specify the type of route features that are output by the tool. The
parameter can be specified using one of the following values:
· TRUE_LINES_WITH_MEASURES— Return the exact shape of the resulting route
based on the underlying streets. Additionally, construct measures so the shape
may be used in linear referencing.
· TRUE_LINES_WITHOUT_MEASURES— Return the exact shape of the resulting route
based on the underlying streets.
· STRAIGHT_LINES— Return a straight line between the incident and the
facility.
· NO_LINES— Do not return any shapes for the routes. This value can be
useful in cases where you are only interested in determining the total travel
time or travel distance between the closest facility and the incident.
When the Route Shape parameter is set to True Shape, the generalization of
the route shape can be further controlled using the appropriate values for the
Route Line Simplification Tolerance parameter.

Output Network Analysis Layer (optional)
Choose whether the output includes a network analysis layer of the
results. In either case, feature classes with routes and directions are
returned. However, a server administrator may want to choose to output a
network analysis layer as well so that the setup and results of the tool can be
debugged using the Network Analyst controls in the ArcGIS Desktop environment.
This can make the debugging process much easier.
In ArcGIS Desktop, the default output location for the network analysis layer
is in the scratch folder. You can determine the location of the scratch folder
by evaluating the value of arcpy.env.scratchFolder geoprocessing environment in
the Python window. The output network analysis layer is stored as an LYR file
whose name begins with _ags_gpna and is followed by an alphanumeric GUID.

Limits how many features can be affected by polygon barriers.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities (optional)
Limits how many facilities can be added to the closest facility analysis.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Facilities to Find (optional)
Limits how many facilities the user can ask the service to find.
This parameter helps you govern the amount of processing that occurs when
solving. For example, you could assign a low value to this parameter for a free
version of the service you are creating and use a higher value for a
paid-subscription version of the service.
A null value indicates there is no limit.
Maximum
Incidents (optional)
Limits how many incidents can be added to the closest facility analysis.

A null value indicates there is no limit.
Force
Hierarchy Beyond Distance (optional)
Specifies the distance after which the solver will force hierarchy, even
if hierarchy is not enabled, when finding closest facilities. The units of this
parameter are the same as those shown in the Distance Attribute Units
parameter.
Finding closest facilities that are far away while using the network's
hierarchy tends to incur much less processing than finding the same closest
facilities without using the hierarchy. This parameter helps you govern the
amount of processing that occurs when solving.
A null value indicates that the hierarchy will never be enforced and the
value of the Use Hierarchy in Analysis parameter will always be honored. If the
input network dataset does not support hierarchy, specifying a value for this
parameter will result in an error. A null value should be used in this case.

Maximum Features Affected by Line Barriers (optional) الحد الأقصى من الميزات التي تتأثر بحواجز الخطوط (اختياري)
Limits how many features
can be affected by line barriers.
يحد من عدد الميزات التي يمكن أن تتأثر بحواجز
الخطوط.
تساعدك هذه المعلمة على التحكم في مقدار المعالجة
التي تحدث عند الحل. على سبيل المثال ، يمكنك تعيين قيمة منخفضة لهذه المعلمة
لإصدار مجاني من الخدمة التي تقوم بإنشائها واستخدام قيمة أعلى لإصدار الاشتراك
المدفوع من الخدمة.
تشير القيمة الفارغة إلى عدم وجود حد.

Maximum Features Affected by Polygon Barriers (optional) الحد الأقصى من الميزات التي تتأثر بحواجز المضلع (اختياري)
Limits how many features
can be affected by polygon barriers.
يحد من عدد العناصر التي يمكن أن تتأثر بحواجز
المضلع.
تساعدك هذه المعلمة على التحكم في مقدار المعالجة
التي تحدث عند الحل. على سبيل المثال ، يمكنك تعيين قيمة منخفضة لهذه المعلمة
لإصدار مجاني من الخدمة التي تقوم بإنشائها واستخدام قيمة أعلى لإصدار الاشتراك
المدفوع من الخدمة.

Maximum Facilities (optional) الحد
الأقصى من الخدمات (اختياري)
Limits how many
facilities can be added to the closest facility analysis.
يحد من عدد المرافق التي يمكن إضافتها إلى أقرب
تحليل للمنشآت.

Maximum Facilities to Find (optional) الحد الأقصى من الخدمات للبحث (اختياري)
Limits how many
facilities the user can ask the service to find.
يحد من عدد المرافق التي يمكن للمستخدم أن يطلب من
الخدمة العثور عليها.

Force Hierarchy Beyond Distance (optional) قوة التسلسل الهرمي ما بعد المسافة (اختياري)
Specifies the distance
after which the solver will force hierarchy, even if hierarchy is not enabled,
when finding closest facilities. The units of this parameter are the same as
those shown in the Distance Attribute Units parameter.
تحدد المسافة التي سيقوم بعدها المحلل بفرض
التسلسل الهرمي ، حتى إذا لم يتم تمكين التدرج الهرمي ، عند البحث عن أقرب
المرافق. وحدات هذه المعلمة هي نفسها الموضحة في معلمة وحدات سمات المسافة.
يميل العثور على أقرب المرافق البعيدة أثناء
استخدام التسلسل الهرمي للشبكة إلى تحمل معالجة أقل بكثير من العثور على أقرب
المرافق دون استخدام التسلسل الهرمي. تساعدك هذه المعلمة على التحكم في مقدار
المعالجة التي تحدث عند الحل.
تشير القيمة الخالية إلى أنه لن يتم فرض التسلسل الهرمي مطلقًا وسيتم دائمًا احترام قيمة معلمة استخدام التدرج الهرمي في التحليل. إذا كانت مجموعة بيانات شبكة الإدخال لا تدعم التسلسل الهرمي ، فسيؤدي تحديد قيمة لهذه المعلمة إلى حدوث خطأ. يجب استخدام قيمة فارغة في هذه الحالة.
