Suggestion for a tool to improve map quality

[Treadly]

I have been testing the routing maps from mkgmap which is working quite well.

I recent had an issue where the GPS would just suddenly say it cannot route but a few minutes down the road would work again.
Eventually I tracked it down to a large freeway interchange where the ways where not connected but they look like they where.

As the nodes where not in the same location, mapnik did not pick it up as a problem so they are difficult to find and spending a while in the area I found a few more.

What I am suggesting is a method to highlight the last node in a way.
This will show up all the no through roads but also the problem I found as you would not expect a no though road on a freeway.

Just a thought

I open up the img file in MapEdit, use the Generate Routing Graph command, and then you can easily see the nodes, in addition you can test it with the routing function. Then you have to go back to potlatch or JOSM to make the change. JOSM needs routing tools similar to Mapedit.
