ArcGIS Pro - Split Line Feature Layer

Question

I am working with an old line feature layer of a road network. I want to update the layer by splitting the roads by intersection. For example, if a road crosses multiple intersections, at each intersection the road would be split creating a new line feature. For one road crossing two intersections would be split into 3 separate features (roads). Is there a tool to do this automatically? Rather than by manually splitting?

The purpose of this is to be able to analyze the roads on a block-by-block basis.

I looked at the Geoprocessing tools and I could not find a tool. I heard the Arc Hydro tool may work.

Answer 1

You could look into arcpy.management.FeatureToLine (Feature To Line).

Here is a Python example using the tool:

import arcpy, arcpy.management

roads = r"d:\temp\test\roads.shp"

segmented_roads = r"d:\temp\test\segmented_roads.shp"

arcpy.management.FeatureToLine(roads, segmented_roads)

However, the tool above is not available in the Basic licence of ArcGIS Pro. You may also want to look into an open-source solution such as using the Split with lines tool from QGIS:
