Summary
Increases the maximum number of edges per turn in a turn feature class.
Usage
Once the maximum number of edges is increased, it cannot be decreased later. So only increase by the needed amount.
Increasing the number of edges by one adds three additional fields to the turn feature class. Take care not to exceed the maximum number of fields allowed by the database being used. For example, a personal geodatabase is limited to 255 fields.
Syntax
IncreaseMaximumEdges_na (in_turn_features, maximum_edges)
| Parameter | Explanation | Data Type |
in_turn_features | The turn feature class that is having its maximum number of edges raised. | Feature Layer |
maximum_edges | The new maximum number of edges in the input turn feature class. The value must be at least one higher than the existing maximum number of edges and cannot be greater than 50. | Long |
Code Sample
IncreaseMaximumEdges example 1 (Python window)
Execute the tool using all parameters.
turns = "C:/Data/SanFrancisco.gdb/Transportation/RestrictedTurns"
arcpy.na.IncreaseMaximumEdges(turns, 8)
IncreaseMaximumEdges example 2 (stand-alone Python script)
The following Python script demonstrates how to use the IncreaseMaximumEdges tool in a stand-alone script.
# Name: IncreaseMaximumEdges_ex02.py
# Description: Increase maximum edges for turn features to 8.
# Requirements: Network Analyst Extension
#Import system modules
import arcpy
from arcpy import env
#Check out the Network Analyst extension license
arcpy.CheckOutExtension("Network")
#Set environment settings
env.workspace = "C:/data/SanFrancisco.gdb/Transportation"
#Set local variables
turn_features = "RestrictedTurns"
max_edges = 8
#Increase the edges for turn features
arcpy.na.IncreaseMaximumEdges(turn_features, max_edges)
print("Script completed successfully.")
