Calculate Route Concurrencies

Summary

Calculates and reports the concurrent route segments within an LRS Network. These concurrencies are reported with the measures for each concurrent route segment and a time range in which the concurrency exists. The route dominance rules for the LRS Network can be used to determine the dominant route in each concurrent section.

Usage

  • The output feature class contains the following fields: NetworkID, RouteID, SectionID, FromMeasure, ToMeasure, FromDate, ToDate, DominantFlag, and DominantError.

Syntax

CalculateRouteConcurrencies_roads (in_network, out_table, {in_tvd}, {find_dominance})
ParameterExplanationData Type
in_network

The network containing the routes on which concurrencies will be calculated.

Feature Layer
out_table

The table to be created, containing all the concurrent sections in the Source LRS Network.

Table
in_tvd
(Optional)

The temporal view date for the network.

Date
find_dominance
(Optional)

Indicates whether to use route dominance rules configured for in_network.

  • FIND_DOMINANCE —Uses route dominance rules configured to determine the dominant route in each concurrent section. This is the default.
  • NO_FIND_DOMINANCE —Does not use route dominance rules configured to determine the dominant route in each concurrent section.
Boolean

Code sample

AppendEvents example 1 (Python window)

Demonstrates how to use the CalculateRouteConcurrencies tool in the Python window in ArcMap.

# tool variables
in_network = r"C:\Data\NY_Data.gdb\LRSN_MilePoint"
out_table = r"C:\Data\NY_Data.gdb\ConcurrenciesOutput"
in_tvd = ""
find_dominance = "FIND_DOMINANCE"

# set current workspace
arcpy.env.workspace = "C:/Data/NY_Data.gdb"

# execute the tool
arcpy.CalculateRouteConcurrencies_roads(in_network, out_table, in_tvd, find_dominance)
AppendEvents example 2 (stand-alone Python script)

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

# Name: FindRouteConcurrencies.py
# Description: Identifies all the route concurrencies in a given network.
# Requires: Esri Roads and Highways Solution

# Import arcpy module
import arcpy

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

# Local variables
network = r"C:\Data\NY_Data.gdb\LRSN_MilePoint"
output_table = r"C:\Data\NY_Data.gdb\Concurrencies_Output"

# Execute the tool
arcpy.CalculateRouteConcurrencies_roads(network, output_table, "", "FIND_DOMINANCE")
