All, I'm after a software product that works out and visualises travel times across the world by road. What I need is the ability to show travel times as radii from a given hub, but intelligently, I.e. factoring in local road quality. So if I picked Dover, it would show significant range up the M2, but less so along the coast where the roads are poorer. This would either be an addon to something like Google Maps or a standalone product. Anyone seen this sort of thing? Thanks!
