Краткая информация
Checks routes on the network for overlaps between linear events.
Использование
The input Event Layer must be one of the linear event tables registered with the input Network Layer.
The Output Feature Class represents the overlaps between linear events.
The Output Feature Class contains the following fields: NetworkName, RouteID, TVD (Temporal View Date), EventLayer, FromMeasure and ToMeasure.

DetectOverlapsForLinearEvents example 1 (in-line)
The following Python window script demonstrates how to use the DetectOverlapsForLinearEvents function in immediate mode.
# tool variables
in_network = "MilePoint"
in_event = "Functional_Class"
out_feature = "Overlaps_Output"
in_tvd = "2/28/2014"
in_to_measure = ""
in_from_measure = ""
in_tolerance = ""
# set current workspace
arcpy.env.workspace = "C:/data/Outputs.gdb"
# execute the tool
arcpy.DetectOverlapsForLinearEvents_locref(in_network, in_event, out_feature, in_tvd, in_to_measure, in_from_measure, in_tolerance)
DetectOverlapsForLinearEvents example 2 (stand-alone Python script)
The following Python script demonstrates how to use DetectOverlapsforLinearEvents in a stand-alone Python script.
# Name: Detect OverlapsForLinearEvents.py
# Description: Convert Roads and Highways Network Layer to Feature Layer and Detect Overlaps for Linear Events in a file geodatabase
# Import arcpy module
import arcpy
# Check out any necessary licenses
arcpy.CheckOutExtension("Highways")
# Local variables
network = r"C:\Data\NY_Data.gdb\LRSN_MilePoint"
event = r"C:\Data\NY_Data.gdb\LRSE_Speed_Limit"
overlaps_Output = r"C:\Data\Outputs.gdb\Gaps_Output"
# Process: Detect Overlaps for linear events
arcpy.env.overwriteOutput = 1
arcpy.DetectOverlapsForLinearEvents_locref(network, event, overlaps_Output)
