Calculate Route Concurrencies (Location Referencing)

摘要

Calculates and reports concurrent route sections in an LRS Network.

使用情况

• 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.

CalculateRouteConcurrencies example 1 (stand-alone script)

Demonstrates how to use the CalculateRouteConcurrencies function as a stand-alone script.

# Name: CalculateRouteConcurrencies_Pro_ex1.py
# Description: Calculates and reports concurrent route sections in an LRS Network in a stand-alone script.
# Requirements: ArcGIS Location Referencing

# Import arcpy module
import arcpy

# Check out any necessary licenses
arcpy.CheckOutExtension("LocationReferencing")

# Local tool variables
in_route_features = r"C:\Data\SampleData.gdb\LRS\NonlineNetwork"
out_dataset = r"C:\Data\SampleData.gdb\LRS\ConcurrentRoutes"
tvd = ""
find_dominance = "FIND_DOMINANCE"
include_geometry = "INCLUDE_GEOMETRY"

# Execute the tool
arcpy.locref.CalculateRouteConcurrencies(in_route_features, out_dataset, tvd, find_dominance, include_geometry)

# Check in licenses
arcpy.CheckInExtension('LocationReferencing')

CalculateRouteConcurrencies example 2 (Python window)

Demonstrates how to use the CalculateRouteConcurrencies function in the Python window.

# Name: CalculateRouteConcurrencies_Pro_ex2.py
# Description: Calculates and reports concurrent route sections in an LRS Network in the Python window.
# Requirements: ArcGIS Location Referencing

# Local tool variables
