Calculate Route Concurrencies (Location Referencing)

Summary

Calculates and reports concurrent route sections in an LRS Network.

Usage

• Overlapping route sections will only be found if the routes share the same centerline. This tool does not identify topologically overlapping routes that use different centerlines.

• Section ID GUIDs are unique for each concurrent section in the network, meaning that each route in a concurrent section will have a record with the same section ID as the other routes in that concurrent section.

• The DominantFlag field has two potential values.

  • 0—A subordinate route in the concurrent section
  • 1—The dominant route in the concurrent section

• The DominantError field has the following potential values:

  • 0—No error occurred when calculating the dominant route in the concurrent section.
  • 1—Two or more routes had the same attribute value for the concurrent section. The dominant route was randomly selected.
  • 2—Null or no values were present for the attribute or attributes used to calculate the dominant route in the concurrent section.
  • 3—Too many values were present for the attribute or attributes used to calculate the dominant route in the concurrent section.
  • 4—One of two conditions were present in the concurrent section: the route was not calibrated in the concurrent section or the centerline that composes the concurrent section did not align with the geometry of the route.

• If the Include Geometry parameter is checked, the output dataset will be a feature class. Otherwise, the output dataset will be a table.

• Specify a Temporal View Date parameter value to calculate concurrency for that point in time. Leaving this field blank shows concurrency across all time.

• It is recommended that you configure route dominance rules for an LRS Network using the Configure Route Dominance Rules tool before running this tool.

Parameters

Dialog

Label	Explanation	Data Type
Input Route Features	The LRS Network feature class in which route concurrencies will be calculated.	Feature Layer
Output Dataset	The feature class or table to which the calculated results will be posted.	Table
Temporal View Date (Optional)	The temporal view date for the network, if one is specified. Leaving this field blank shows all time.	Date
Set route dominance based on priority rules (Optional)	Specifies whether configured route dominance rules will be used to set dominance. Checked—Configured route dominance rules will be used to determine the dominant route in each concurrent section. This is the default. Unchecked—Configured route dominance rules will not be used to determine the dominant route in each concurrent section.	Boolean
Include Geometry (Optional)	Specifies whether geometry will be included in the output dataset. Checked—Geometry will be included in the output dataset. Unchecked—Geometry will not be included in the output dataset. This is the default.	Boolean

Python

arcpy.locref.CalculateRouteConcurrencies(in_route_features, out_dataset, {tvd}, {find_dominance}, {include_geometry})

Name	Explanation	Data Type
in_route_features	The LRS Network feature class in which route concurrencies will be calculated.	Feature Layer
out_dataset	The feature class or table to which the calculated results will be posted.	Table
tvd (Optional)	The temporal view date for the network, if one is specified. Leaving this field blank shows all time.	Date
find_dominance (Optional)	Specifies whether configured route dominance rules will be used to set dominance. FIND_DOMINANCE—Configured route dominance rules will be used to determine the dominant route in each concurrent section. This is the default. NO_FIND_DOMINANCE—Configured route dominance rules will not be used to determine the dominant route in each concurrent section.	Boolean
include_geometry (Optional)	Specifies whether geometry will be included in the output dataset. EXCLUDE_GEOMETRY—Geometry will not be included in the output dataset. This is the default. INCLUDE_GEOMETRY—Geometry will be included in the output dataset.	Boolean
