1.    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:

Time of Day Usage (optional)

Indicates whether the Time of Day parameter value represents the arrival or departure time for the routes.

Time Zone for Time of Day (optional)

Specifies the time zone of the Time of Day parameter.

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:

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:

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:

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.

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.

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:

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.

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.

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.

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:

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.

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 اليوم" تمثل وقت الوصول أو وقت المغادرة للمسارات.

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.

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.

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.

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.

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)

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)

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.

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:

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.

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.

A null value indicates there is no limit.

Maximum Facilities (optional)

Limits how many facilities 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.

4.    Time Zone for Time of Day (optional) المنطقة الزمنية للوقت من اليوم (اختياري)

Specifies the time zone of the Time of Day parameter.

يحدد المنطقة الزمنية لمعلمة الوقت من اليوم.

GEO_LOCAL - تشير معلمة "وقت اليوم" إلى المنطقة الزمنية التي توجد بها المرافق أو الأحداث.

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:

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:

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.

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.

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:

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.

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.

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.

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:

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.

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.

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.

7.    Line Barriers (optional) حواجز الخطوط (اختياري)

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:

يحدد حواجز الخط ، والتي تقيد الاجتياز عبرها مؤقتًا. يتم تحديد حواجز الخط من خلال مجموعة الميزات. يتم سرد الحقول الموجودة في جدول السمات ووصفها أدناه.

معرف الكائن:

حقل المعرف الذي يديره النظام.

شكل:

يشير الحقل الهندسي إلى الموقع الجغرافي لكائن تحليل الشبكة.

اسم:

اسم الحاجز.

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:

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.

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.

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:

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.

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.

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.

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:

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.

Maximum Features Affected by Point Barriers (optional)

Limits how many features can be affected by point barriers.

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.

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.

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.

Specify whether hierarchy should be used when finding the shortest routes between points.

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.

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.

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.

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:

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.

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.

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.

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:

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.

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 الوقت (اختياري)

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

تحدد سمة تكلفة الشبكة لاستخدامها عندما تكون قيمة وحدات القياس وحدة زمنية.

تقوم الأداة بإجراء التحويل الضروري للوحدة الزمنية عندما تختلف قيمة وحدات القياس عن وحدات سمة التكلفة المحددة هنا. بمعنى آخر ، لا يلزم أن تكون الوحدات الزمنية للقطع الافتراضي وسمة تكلفة الشبكة متطابقة.

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:

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.

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.

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.

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:

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.

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.

13. Use Hierarchy in Analysis (optional) استخدام التسلسل الهرمي في التحليل (اختياري)

Specify whether hierarchy should be used when finding the shortest routes between points.

حدد ما إذا كان يجب استخدام التدرج الهرمي عند البحث عن أقصر المسارات بين النقاط.

• تم التحديد (صواب) - استخدم التسلسل الهرمي عند البحث عن المسارات. عند استخدام التسلسل الهرمي ، تفضل الأداة الشوارع ذات الترتيب الأعلى (مثل الطرق السريعة) على الشوارع ذات الترتيب المنخفض (مثل الطرق المحلية) ويمكن استخدامها لمحاكاة تفضيل السائق للسفر على الطرق السريعة بدلاً من الطرق المحلية حتى لو كان ذلك يعني رحلة أطول. هذا صحيح بشكل خاص عند العثور على طرق إلى مرافق بعيدة ، لأن السائقين في الرحلات الطويلة يميلون إلى تفضيل السفر على الطرق السريعة حيث يمكن تجنب التوقف والتقاطعات والانعطافات. يعد استخدام التسلسل الهرمي أسرع من الناحية الحسابية ، خاصة بالنسبة للمسارات طويلة المدى ، لأنه يتعين على الأداة تحديد المسار الأفضل من مجموعة فرعية أصغر نسبيًا من الشوارع. هذه هي القيمة الافتراضية.

• غير محدد (خطأ) - لا تستخدم التسلسل الهرمي عند البحث عن المسارات. إذا لم يتم استخدام التدرج الهرمي ، فإن الأداة تأخذ في الاعتبار جميع الشوارع ولا تفضل الشوارع ذات الترتيب الأعلى عند البحث عن المسار. غالبًا ما يستخدم هذا عند البحث عن طرق قصيرة المسافة داخل المدينة.

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:

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)

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.

Specify by how much you want to simplify the route geometry.

حدد حسب المقدار الذي تريده لتبسيط هندسة المسار.

تتجاهل الأداة هذه المعلمة إذا لم يتم تعيين معلمة شكل المسار على خطوط حقيقية ذات مقاييس أو خطوط حقيقية بدون مقاييس.

يحافظ التبسيط على النقاط الحرجة على المسار ، مثل المنعطفات عند التقاطعات ، لتحديد الشكل الأساسي للمسار وإزالة النقاط الأخرى. مسافة التبسيط التي تحددها هي أقصى إزاحة مسموح بها يمكن للخط المبسط أن ينحرف عنها عن الخط الأصلي. يؤدي تبسيط الخط إلى تقليل عدد النقاط التي تشكل جزءًا من هندسة المسار. هذا يحسن وقت تنفيذ الأداة.

يتم تجاوز قيمة هذه المعلمة عند تعيين وضع السفر (Travel_Mode في Python) على أي قيمة بخلاف القيمة المخصصة.

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.

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.

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:

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.

28. 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.

29. 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.

تشير القيمة الفارغة إلى عدم وجود حد.

30. 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.

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.

31. 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.

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.

32. Maximum Incidents (optional) الحد الأقصى للحوادث (اختياري)

Limits how many incidents can be added to the closest facility analysis.

يحد من عدد الحوادث التي يمكن إضافتها إلى أقرب تحليل للمنشأة.

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.

33. 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.
