Output from Generate Service Areas

The Generate Service Areas geoprocessing tool produces a ServiceAreas feature class as output. The output feature class, and its corresponding field attributes, are described in this topic.

ServiceAreas feature class

The ServiceAreas polygon feature class represents the regions of the network that can be reached within the given travel time. The default name of this output feature class is ServiceAreas, but you can give it a different name by changing the Service Areas parameter prior to solving.

The ServiceAreas feature class is assigned the same coordinate system that the underlying network dataset uses. This can be controlled by specifying a value for the Output Coordinate System geoprocessing environment.

The field names of the ServiceAreas feature class are listed and described below.

Field name	Description
ObjectID	The system-managed ID field.
Shape	The geometry of the polygon, which is stored internally. One influential factor in determining the shape of the output polygon is whether Use Hierarchy in Analysis is checked at solve time. Be aware that if hierarchy is used, the polygon may overlap some lower-order roads that can't truly be reached within the given distance, travel time, or other break impedance.
Name	The name of the service area polygon is based on the name of the associated facility and the break range; for instance, Location1: 0.0 – 5.0 would represent a polygon that covers all traversable edges within five minutes of facility Location1.
FacilityID	The unique ID of the associated facility.
FromBreak	The lower bound of the polygon's break range. The value is in the units specified by the Break Units parameter.
ToBreak	The upper bound of the polygon's break range. The value is in the units specified by the Break Units parameter.
