This doesn't correspond to reality: I believe that an emergency vehicle can cross a solid line, while of course they would have problems with a physically separated road. Also, the presence and style of line in the middle of the road gives additional informations that could be useful for the users. * Dashed line: you can overtake wide veicles; probably related to the available speed and chances to be blocked by something slow. * No line: this road is not wide enough to have two proper lanes: if you meet another car have to slow down, or possibly even stop; a router can use this information to choose another slighty longer, but wider road, even in the absence of a precise width tag. -- Elena ``of Valhalla'' _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
