regression in r1431

Hi list, I found a grave routing difference between mkgmap r1430 and r1431, when I set routing to "bicycle", "shortest route". r1430 (and older) sends me right to my target; r1432 (and newer) meanders around like there's no other things to do than pedaling around in the countryside. Really: a mere 15 kilometer trip will increase to 57 kilometers! I'd guess this is mainly because of: -highway=unclassified [0x06 road_class=1 road_speed=2 resolution 21] +highway=unclassified [0x06 road_class=0 road_speed=3 resolution 21] ... but other factors in r1431 may add to this. As far as I can see from the mailing list, r1431 patch *improves* routing over large distances (see mailing list, messages with subject "Patch for better Autorouting", 2009-12-01 and further). Now what to do? (Maybe it's time to have a separate bicycle routing style in mkgmap?) Best regards, Valentijn

Hi, in my personal style I try to avoid road_class 0 (only use them for tracks and living_streets and footpaths). Sometimes Mapsource even preferred to use direct-line routing instead of using class 0 roads. :-( Chris
