enter image description hereUsing Network Analyst on ArcGIS Pro and a preconfigured streets network, I am trying to use the "Route" tool to solve the fastest way to service 20 different routes with 7-20 locations per route. However, each route I have solved goes completely against intuition. The stops are sequenced in ways that backtrack and cost more time than they should. For Sequence in the travel settings, I am using "Find Best." For input locations, I have separate feature classes for each of the twenty layers that contain all of the points in that route. I am trying to figure out if I am missing a crucial Network Analyst setting or if the network layer I am using might have been configured incorrectly. I included a picture of the shortest route just to showcase the type of problem I'm having.

Route goes far north, south, then far north again

  • Can you include a screenshot of your settings? I've seen odd results with a time of day set or when coming back to the start point. – MaryBeth Sep 28 '18 at 15:47
  • I added that. I also created a new network dataset and I am still having the same issue. Routes are all over the place! – Jeff Sep 28 '18 at 15:52

    I'd try to solve individual routes: from 2 to 4 and from 2 to 3 (using the numbers shown on your image). Very unlikely, but could you have oneway restrictions on most of your roads making it impossible for the solver to travel in a certain direction (forcing your best route to go crazy)? Any live/historic traffic enabled - this could make the route to change against intuition? Any hard time windows where the stops should be visited? Also, I'd start debugging solving simple routes in a smaller area to see how the solver behave before expanding the geographic area. – Alex Tereshenkov Sep 28 '18 at 16:44
  • Wouldn't setting Not Using Time under Arrive/Depart prevent from incorporating the traffic data? Also, in the new network dataset I created I did not set any one way restrictions (We really don't have many one way streets here anyways) and I am still getting the same results. I'll try starting a bit smaller, but it seems like at that point I am pretty much designing the routes myself. – Jeff Sep 28 '18 at 16:55
  • Are you ever actually calculating a route (using a tool like find routes/generate routes/etc) or just adding stops to the map, which is what Add Locations does? – MaryBeth Oct 1 '18 at 14:51
