Assume there are 12 crossroads for a user want to visit in a city. Could you help to find a best way without U-Turns?
Please see the attach for details.
Here is a result with U-Turns in ArcMap. It's not the solution for the question.
1 2 3 4 6 7 5 9 11 8 10 12 11
There is an easy if not a little complex way. you can generate a near analysis on each point to find the point that is closest to it. start off by drawing lines between a point and its closest neighbor
9 would go to 11
12 to 11
10 to 12 and in this case 8 might go to 9
3 and 4 would partner up but instead go to 6
It could be work for regular network, however the nearest stop might not be the closet stop in a network.
And it not avoid U-Turn.
Then you would need to include roads in with your diagram and question.
I once did something similar for my mother in law when she wanted to visit all the assisted living facilities in my town.
however, I simply put the addresses into Google Maps and kept sliding stops up and down until I got the shortest route.
