Sure I'm using speed data from OSM and if not available, set it based on way type and common speeds. I can find shortest and fastest path. No detection if road is in the city yet.
I made some progress in last days and I'm going to use it for the first time to drive home today :) Bastian Muck wrote: > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Mike Crash schrieb: >> I use A* for routing, it is usable, but still not what I expect. >> But I have some improvements in my mind :) I need to create >> rerouting now and to test it in real life > > I don't have any idea, how the code looks like, but I guess, that you > use gps-positions as heuristic and distances as edge-weights.
