Generate Service Areas

Creates a service area network analysis layer, sets the analysis properties, and solves the analysis. This tool is ideal for setting up a service area geoprocessing service on the web. A network service area is a region that encompasses all streets that can be accessed within a given distance or travel time from one or more facilities.

Service areas are commonly used to visualize and measure accessibility. For example, a 3-minute drive-time polygon around a grocery store can determine which residents are able to reach the store within 3 minutes and are thus more likely to shop there.

The Generate Service Areas and Make Service Area Layer tools are similar, but they are designed for different purposes. Use Generate Service Areas if you are setting up a geoprocessing service; it will simplify the setup process; otherwise, use Make Service Area Layer. Also, use Make Service Area Layer if you need to generate service area lines; Generate Service Areas doesn't provide the option to generate lines.

To create a service-area geoprocessing service using Generate Service Areas, you only need to set up one tool, and you can publish the tool directly as a service. In contrast, you need to create a model with the Make Service Area Layer, properly connect it to various other tools, and publish the model to create a service-area geoprocessing service. See Geoprocessing service example: Drive-time polygons to learn how to set up a drive-time polygons service using tutorial data. One other option to consider is the ArcGIS Online Generate Service Areas service. The service runs like a geoprocessing tool in ArcMap, can be accessed from other applications, and includes high-quality road data for much of the world.

1.    Facilities

The facilities around which service areas are generated.

The facilities feature set has three attributes:

ObjectID:

The system-managed ID field.

Shape:

The geometry field indicating the geographic location of the network analysis object.

Name:

The name of the facility. If the name is empty, blank, or null, a name is automatically generated at solve time.

2.    Break Values

Specifies the size and number of service area polygons to generate for each facility. The units are determined by the Break Units value.

When the Generate Service Areas tool runs, a noteworthy interaction occurs among the following parameters: Break Values, Break Units, and either Time Attribute or Distance Attribute. Together, Break Values and Break Units define how far or how long the service area should extend around the facility or facilities. The Time Attribute and Distance Attribute parameters each define one network cost attribute. Only one of these two cost attributes is used, however, and the one that the solver chooses to use corresponds with the Break Units value; that is, when you specify a time-based Break Units value, such as seconds or minutes, the tool solves using the cost attribute defined in the Time Attribute parameter. When you specify a distance-based Break Units value, such as kilometers or miles, it uses the cost attribute defined in the Distance Attribute parameter.

Multiple polygon breaks can be set to create concentric service areas per facility. For instance, to find 2-, 3-, and 5-mile service areas for each facility, enter 2 3 5, separating the values with a space. Set Break Units to Miles and ensure that you have chosen a distance-based network attribute for the Distance Attribute parameter.

3.    Break Units

The units for the Break Values parameter.

1. Meters
2. Kilometers
3. Feet
4. Yards
5. Miles
6. Nautical Miles
7. Seconds
8. Minutes
9. Hours
10. Days

The Generate Service Areas tool chooses whether to use the network cost attribute specified in the Time Attribute or Distance Attribute parameter depending on whether the units you specify here are time or distance based.

The tool performs the necessary units conversion when the Break Units value differs from the units of the corresponding time or distance cost attribute.

4.    Network Dataset

The network dataset on which the analysis will be performed. Network datasets most often represent street networks but may represent other kinds of transportation networks as well. The network dataset needs at least one time-based and one distance-based cost attribute.

5.    Service Areas

The output workspace and name of the output features. This workspace must already exist. The default output workspace is in_memory.

6.    Travel Mode (optional)

Choose the mode of transportation for the analysis. Custom is always a choice. For other travel mode names to appear, they must be present in the network dataset specified in the Network Dataset parameter.

A travel mode is defined on a network dataset and provides override values for parameters that, together, model cars, trucks, pedestrians, or other modes of travel. By choosing a travel mode here, you don't need to provide values for the following parameters, which are overridden by values specified in the network dataset:

1. UTurn Policy
2. Time Attribute
3. Time Attribute Units
4. Distance Attribute
5. Distance Attribute Units
6. Use Hierarchy in Analysis
7. Restrictions
8. Attribute Parameter Values
9. Polygon Simplification Tolerance
10. CUSTOM—Define a travel mode that fits your specific needs. When Custom is chosen, the tool does not override the travel mode parameters listed above. This is the default value.
