I have run the shortest Path Algorithm in Network Analyst for trash pickup and selected "U-turn at intersection and dead-ends" which is required but I don't want it to take U-turn on 3-ways stop junctions. What can I do to avoid this?
Also, I wanted to know how can I put truck height restrictions. I am using network dataset provided by ESRI.
U-Turns at three way junctions are rare and can happen when there are one-way streets, and side of street/curb approach set to right or left side. So can you choose the U-Turns Not Allowed option and re-route? If that is not a possibility then you will have a edit the network dataset and add a turn restriction at that location.
