I've seen some questions tackle this issue, but havent myself found a working solution. Using ArcMap 10.2.2 Advanced with Network Analyst.
I use the Vehicle Routing Problem to route a couple delivery vehicles around, some resultant routes overlap.
Is there anyway to show all the routes at once? From my picture for instance, the intersection of the yellow/red/green lines, I would like to see all 3 travelling down Valley Blvd, instead of the highest ranked route.
