hi all
I have 404 pairs of origins and destinations, and I created 404 routes, one route for each pair.
I used road centre line to create the network.
So as you can imagine, one piece of road may be picked up by a lot of routes, or in other words, different routes have common parts.
My problem is I want to use width of road to show the frequency of piece of road being picked up by routes. Or any better way to show the results is welcome. It is not straightforward to see the map because all the routes are just piled up.
