Hi All,
As the document mentioned, "Currently when a network location is on a junction, the ArcGIS Network Analyst extension allows U-turns there, even when its CurbApproach property is set to No U-Turns and the U-turns at Junctions property of the network analysis layer is set to Not Allowed."
My question is when the stop is set as a street override (As we don't know which direction is best for the crossroad), how to avoid a U-Turn in this scenario?
The U-Turn policy is "Allowed Only at DeadEnds".
Environment:
ArcGIS Desktop 10.6 with Network Analysis Extension
Thanks,
Leo
When a stop is located on a junction than the curb approach property does not make sense as you can not figure out which way is the left or right side of that location. This is documented here:
U-turn policies—Help | ArcGIS Desktop
You can see the caution note in the curb approach section:
And this also explains that the U-turn at junction property applies to junction that occur in between stops.
So a way to not get into this issue is to locate your stops only on edges and not on system or override junctions of a network dataset. You can control what network sources to locate on from the route analysis layer's properties or on the add locations tool.
