ServiceArea output data types

Upon successful execution, the tool returns the service areas around the facilities and the status indicating the analysis was successful.

The output data types containing the results from a service area analysis are described below.

Polygons

It provides access to polygon features that represent areas that can be reached from the input locations with a given travel time, travel distance, or travel cost.

This data type supports the fields described below. In addition to these fields, the data type also includes all the fields from the input feature class used as facilities for the analysis when generating overlapping or nonoverlapping polygons.

Field	Description	Data type
Name	The name of the service area. It is based on the name of the associated facility and the cutoffs; for example, Store1: 0.0 – 5.0 represents a service area that covers all traversable streets within five minutes of a facility named Store1. The break values are returned without the name of the facility, for example, 0.0 – 5.0, when the geometryAtOverlap property of the analysis object is set to ServiceAreaOverlapGeometry.Dissolve.	Text
FacilityID	The unique identifier of the associated facility that is automatically generated by the analysis. Multiple facilities can be associated with one service area when the geometryAtOverlap property of the analysis object is set to ServiceAreaOverlapGeometry.Dissolve; therefore, FacilityID field values are set to null when service areas are merged.	Long
FacilityOID	The ObjectID value of the input facility feature used to generate the service area polygon. This field is often used to join information from the input facilities. Multiple facilities can be associated with one service area when the geometryAtOverlap property of the analysis object is set to ServiceAreaOverlapGeometry.Dissolve; therefore, FacilityOID field values are set to null when service areas are merged.	Long
FromBreak	The lower bound of the service area's impedance cutoff range. The unit for this field is based on the unit of the impedance attribute set for the analysis. If the impedance attribute is time based, the value is in the units specified by the timeUnits property. If the impedance attribute is distance based, the value is in the units specified by the distanceUnits property. The value is in unknown units if the impedance attribute is neither time based nor distance based.	Double
ToBreak	The upper bound of the service area's impedance cutoff range. The value is in the same units as the FromBreak field values.	Double
Breaks	The values for this field are copied from the Breaks field on the input facilities.	Text
AdditionalTime	The values for this field are copied from the AdditionalTime field on the input facilities.	Double
AdditionalDistance	The values for this field are copied from the AdditionalDistance field on the input facilities.	Double
AdditionalCost	The values for this field are copied from the AdditionalCost field on the input facilities.	Double

Lines

This stores the resultant service areas as linear features and covers the streets, or network edges, that can be reached within the given time, distance, or other travel-cost cutoff. Lines are a truer representation of a service area than polygons since service area analyses are based on measurements along the network lines.

This data type supports the following fields:

Field	Description	Data type
FacilityOID	The ObjectID value of the input facility feature used to generate the service area lines. This field is often used to join information from the input facilities.	Long
SourceName	Each service area line traverses a feature from a network source feature class—a feature class used to create the network dataset on which the service area analysis is performed. This field contains the name of the edge source feature class from which the line was generated.	Text
SourceOID	The ObjectID of the traversed street feature. Summarizing the values for this field can provide useful information such as the number of times a particular street feature is included from the facilities.	Long
FromPosition	Specifies where along the underlying source feature the service area line begins. A value of 0 (zero) indicates that the service area line begins at the from point of the underlying source feature. A value of 1 indicates that the service area line begins at the to point of the source feature. A value between 0 and 1 indicates that the line begins at a point along the underlying source feature; for example, a value of 0.25 means the line begins 25 percent along the digitized direction of the underlying source feature.	Double
ToPosition	Specifies where along the underlying source feature the service area line ends. A value of 0 (zero) indicates that the service area line ends at the from point of the underlying source feature. A value of 1 indicates that the service area line ends at the to point of the source feature. A value between 0 and 1 indicates that the line ends at a point along the underlying source feature; for example, a value of 0.25 means the line ends 25 percent along the digitized direction of the underlying source feature.	Double
FromCumul_Minutes	This field contains the cumulative cost, in minutes, of the path from the facility to the beginning of the line feature. The cost of the adjacent junction at the beginning of the line is included in this value. Note: An additional field, FromCumul_[TimeUnits], is included if the timeUnits property of the analysis object is not set to TimeUnits.Minutes. The field values are in the units specified by the timeUnits property. Note: Additional fields, FromCumul_[AccumulateAttributeName]_[TimeUnits], are included for each time-based cost attribute that is accumulated during the analysis.	Double
ToCumul_Minutes	This field contains the cumulative cost, in minutes, of the path from the facility to the end of the line feature. The cost of the adjacent junction at the end of the line is excluded from this value. Note: An additional field, ToCumul_[TimeUnits], is included if the timeUnits property of the analysis object is not set to TimeUnits.Minutes. The field values are in the units specified by the timeUnits property. Note: Additional fields, ToCumul_[AccumulateAttributeName]_[TimeUnits], are included for each time-based cost attribute that is accumulated during the analysis.	Double
FromCumul_Miles	This field contains the cumulative cost, in miles, of the path from the facility to the beginning of the line feature. The cost of the adjacent junction at the beginning of the line is included in this value. Note: An additional field, FromCumul_[DistanceUnits], is included if the distanceUnits property of the analysis object is not set to DistanceUnits.Miles or DistanceUnits.Kilometers. The field values are in the units specified by the distanceUnits property. Note: Additional fields, FromCumul_[AccumulateAttributeName]_[DistanceUnits], are included for each distance-based cost attribute that is accumulated during the analysis.	Double
ToCumul_Miles	This field contains the cumulative cost, in miles, of the path from the facility to the end of the line feature. The cost of the adjacent junction at the end of the line is excluded from this value. Note: An additional field, ToCumul_[DistanceUnits], is included if the distanceUnits property of the analysis object is not set to DistanceUnits.Miles or DistanceUnits.Kilometers. The field values are in the units specified by the distanceUnits property. Note: Additional fields, ToCumul_[AccumulateAttributeName]_[DistanceUnits], are included for each distance-based cost attribute that is accumulated during the analysis.	Double
FromCumul_Kilometers	This field is analogous to the FromCumul_Miles field, except the field values are in kilometers instead of miles.	Double
ToCumul_Kilometers	This field is analogous to the ToCumul_Miles field, except the field values are in kilometers instead of miles.	Double
FromCumul_Other	This field contains the cumulative cost, in unknown units, of the path from the facility to the beginning of the line feature. The cost of the adjacent junction at the beginning of the line is included in this value. This field is included only when the travel mode used for the analysis has an impedance attribute that is neither time based nor distance based. Note: Additional fields, FromCumul_[AccumulateAttributeName]_Other, are included for each cost attribute that is neither time based nor distance based and accumulated during the analysis.	Double

Status	Indicates how the facility was evaluated in the analysis. The possible values are the following: 0 (OK)—The facility was successfully located on the transportation network and analyzed. 1 (Not Located)—The facility was not included in the analysis since a traversable road was not found within the maximum search distance from the facility. 3 (Elements not traversable)—The network element that the facility is on is not traversable. This can occur when the network element is restricted by a restriction attribute. 4 (Invalid Field Values)—Field values fall outside a range or coded-value domain. For example, a negative number may exist where positive numbers are required. 5 (Not Reached)—The facility couldn't be reached due to constraints; for example, a curb approach is set so that a vehicle must travel in the wrong direction on a one-way street to reach the facility. 7 (Not located on closest)—The closest network location to the facility is not traversable because of a restriction or barrier, so the facility has been located on the closest traversable network feature instead.
