ClosestFacility output data types

The output data types containing the results from a closest facility analysis are described.

ClosestFacilities and Facilities

This provides access to the output facilities from a closest facility analysis.

The ClosestFacilities data type includes only those facilities from the set of input facilities that were closest to at least one incident. The Facilities data type includes all the facilities from the analysis, including the facilities that cannot be reached from any of the incidents. You can use the Status field from the Facilities data type to determine why a facility was not used in the analysis.

These data types support the fields described below. In addition to these fields, the data types also include all the fields from the input feature class used as facilities for the analysis.

Field name	Description	Data type
ObjectID	The object ID of the feature.	ObjectID
Name	The name of the facility. The values for this field are copied from the Name field on the input facilities.	Text
SourceID	The numeric identifier of the network dataset source feature class on which the input point is located.	Long
SourceOID	The ObjectID of the feature in the source on which the input point is located.	Long
PosAlong	The position along the digitized direction of the source line feature. This value is stored as a ratio. This field is null if the network location references a junction.	Double
SideOfEdge	The side of the edge in relation to the digitized direction of the line feature. This field is limited to a domain of two values: Right Side (1) and Left Side (2).	Long
CurbApproach	The direction a vehicle may arrive at and depart from the facility. The values for this field are copied from the CurbApproach field on the input facilities.	Long
Status	Specifies the status of the point with respect to its location on the network and the outcome of the analysis. The possible values are the following: 0 (OK)—The point was located on the network. 1 (Not Located)—The point was not located on the network and was not included in the analysis. 2 (Network element not located)—The network element identified by the point's network location fields can't be found. This can occur when a network element where the point should be was deleted, and the network location was not recalculated. 3 (Element not traversable)—The network element that the point is located on is not traversable. This can occur when the 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 exists where positive numbers are required. 5 (Not Reached)—The point can't be reached by the solver. The point may be on a separate, disconnected area of the network from the other inputs, or barriers or restrictions prevent travel to or from the point. 6 (Time window violation)—The point could not be reached within the designated time windows. This status only applies to network analysis types that support time windows. 7 (Not located on closest)—The closest network location to the point is not traversable because of a restriction or barrier, so the point has been located on the closest traversable network feature instead.
