Make Service Area Layer Tool

Make Service Area Layer

Makes a service area network analysis layer and sets its analysis properties. A service area analysis layer is useful in determining the area of accessibility within a given cutoff cost from a facility location.

1.    Input Analysis Network أدخل تحليل الشبكة

The network dataset on which the service area analysis will be performed.

مجموعة بيانات الشبكة التي سيتم إجراء تحليل منطقة الخدمة عليها.

Output Layer Name

Name of the service area network analysis layer to create.

Impedance Attribute

The cost attribute to be used as impedance in the analysis.

Travel From or To Facility (optional)

Specifies the direction of travel to or from the facilities.

Using this option can result in different service areas on a network with one-way restrictions and having different impedances based on direction of travel. The service area for a pizza delivery store, for example, should be created away from the facility, whereas the service area of a hospital should be created toward the facility.

Default Break Values (optional)

Default impedance values indicating the extent of the service area to be calculated. The default can be overridden by specifying the break value on the facilities.

Multiple polygon breaks can be set to create concentric service areas. For instance, to find 2-, 3-, and 5-minute service areas for the same facility, specify "2 3 5" as the value for the Default break values parameter (the numbers 2, 3, and 5 should be separated by a space).

Time of Day (optional)

The time to depart from or arrive at the facilities of the service area layer. The interpretation of this value as a depart or arrive time depends on whether travel is away from or toward the facilities.

If you have chosen a traffic-based impedance attribute, the solution will be generated given dynamic traffic conditions at the time of day specified here. A date and time can be specified as 5/14/2012 10:30 AM.

Instead of using a particular date, a day of the week can be specified using the following dates:

For example, to specify that travel should begin at 5:00 p.m. on Tuesday, specify the parameter value as 1/2/1900 5:00 PM.

Repeatedly solving the same analysis, but using different Time of Day values, allows you to see how a facility's reach changes over time. For instance, the five-minute service area around a fire station may start out large in the early morning, diminish during the morning rush hour, grow in the late morning, and so on throughout the day.

Accumulators (optional)

A 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 Impedance Attribute parameter to calculate the route.

For each cost attribute that is accumulated, a Total_[Impedance] property is added to the routes that are output by the solver.

Use Hierarchy in Analysis (optional)

The parameter is disabled if a hierarchy attribute is not defined on the network dataset used to perform the analysis.

Line Type (optional)

Specifies the type of lines to be generated based on the service area analysis. Selecting the True Lines or True lines with measures option for large service areas will increase the amount of memory consumed by the analysis.

Overlap Lines (optional)

Determines if overlapping lines are generated when the service area lines are computed.

Split Lines when They Cross a Service Area Break (optional)

Include Network Source Fields in Lines (optional)

Polygon Type (optional)

Specifies the type of polygons to be generated.

If your data is of an urban area with a gridlike network, the difference between generalized and detailed polygons would be minimal. However, for mountain and rural roads, the detailed polygons may present significantly more accurate results than generalized polygons.

Merge Polygons with Similar Ranges (optional)

Specifies the options to merge polygons that share similar break values. This option is applicable only when generating polygons for multiple facilities.

Polygon Nest Option (optional)

Specifies the option to create concentric service area polygons as disks or rings. This option is applicable only when multiple break values are specified for the facilities.

Exclude Sources from Polygon Generation (optional)

Specifies the list of network sources to be excluded when generating the polygons. The geometry of traversed elements from the excluded sources will be omitted from all polygons.

This is useful if you have some network sources that you don't want to be included in the polygon generation because they create less accurate polygons or are inconsequential for the service area analysis. For example, while creating a drive time service area in a multimodal network of streets and rails, you should choose to exclude the rail lines from polygon generation so as to correctly model where a vehicle could travel.

Excluding a network source from service area polygons does not prevent those sources from being traversed. Excluding sources from service area polygons only influences the polygon shape of the service areas. If you want to prevent traversal of a given network source, you must create an appropriate restriction when defining your network dataset.

Trim Polygons (optional)

Polygon Trim (optional)

Specifies the distance within which the service area polygons are trimmed. The parameter includes a value and units for the distance. The default value is 100 meters.

U-Turn 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 this, 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.

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.

Restrictions (optional)

A list of restriction attributes to apply during the analysis.

وقت المغادرة أو الوصول إلى مرافق طبقة منطقة الخدمة. يعتمد تفسير هذه القيمة كوقت مغادرة أو وصول على ما إذا كان السفر بعيدًا عن المرافق أو باتجاهها.

• يمثل وقت المغادرة إذا تم ضبط "السفر من أو إلى" على TRAVEL_FROM.

• يمثل وقت الوصول إذا تم تعيين "السفر من أو إلى" على TRAVEL_TO.

إذا اخترت سمة المعاوقة المستندة إلى حركة المرور ، فسيتم إنشاء الحل وفقًا لظروف حركة المرور الديناميكية في الوقت المحدد هنا من اليوم. يمكن تحديد التاريخ والوقت كـ 14/5/2012 10:30 صباحًا.

بدلاً من استخدام تاريخ معين ، يمكن تحديد يوم من أيام الأسبوع باستخدام التواريخ التالية:

• اليوم - 12/30/1899

• الأحد - 12/31/1899

• الاثنين - 1/1/1900

• الثلاثاء - 1/2/1900

• الأربعاء - 1/3/1900

• الخميس - 1/4/1900

• الجمعة - 1/5/1900

• السبت - 1/6/1900

على سبيل المثال ، لتحديد أن السفر يجب أن يبدأ في الساعة 5:00 مساءً. في يوم الثلاثاء ، حدد قيمة المعلمة كـ 1/2/1900 5:00 مساءً.

يسمح لك حل نفس التحليل بشكل متكرر ، ولكن باستخدام قيم مختلفة للوقت من اليوم ، بمعرفة كيف يتغير مدى وصول المنشأة بمرور الوقت. على سبيل المثال ، قد تبدأ منطقة الخدمة التي تبلغ مدتها خمس دقائق حول محطة الإطفاء بشكل كبير في الصباح الباكر ، وتتقلص خلال ساعة الذروة الصباحية ، وتنمو في وقت متأخر من الصباح ، وهكذا على مدار اليوم.

يحدد المسافة التي يتم قطع مضلعات منطقة الخدمة ضمنها. تتضمن المعلمة قيمة ووحدات للمسافة. القيمة الافتراضية هي 100 متر.

U-Turn 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 this, 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.

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.

19. U-Turn Policy (optional) السياسة (اختياري)

سياسة U-Turn عند التقاطعات. يعني السماح بالدوران على شكل حرف U أنه يمكن للحل أن يستدير عند تقاطع طرق ويتضاعف 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. لاستيعاب ذلك ، 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 الخاصة بموقع الشبكة الفردي لمنع انعطاف U هناك أيضًا.

ALLOW_DEAD_ENDS_ONLY - يحظر الدوران للخلف في جميع التقاطعات ، باستثناء تلك التي لها حافة مجاورة واحدة (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.

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.
