Pfft, I was taught to drive on gravel roads, and they can be perfectly safe to drive on at 100km/hr in places, but you have to be familiar with the stretch of road you're on and drive for the condition etc. > i want to tag these accurately, and am doing so, but i should think > that the routing engines ought to avoid, when possible, this combination > or others like it: > > highway=unclassified > name=Mead Road > maxspeed=55 mph > surface=dirt Dirt isn't very useful information imho, in Australia dirt roads could be made of gravel, black soil, red soil etc, and knowing the type of dirt road is useful, gravel roads are often still usable after lots of rain, but you definitely don't want to do black soil roads after heavy rain. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
