http://wiki.openstreetmap.org/wiki/Editing_Standards_and_Conventions#Divided_highways "A divided highway (also separated highway) is any highway where traffic flows are physically separated by a barrier (e.g., grass, concrete, steel), which prevents movements between said flows. " While in the case of sidewalks there is indeed a physical separation (the kerb), it still doesn't quality because that kerb doesn't prevent movements between said flows. >> and adding a separate highway=footway indicates that there is a barrier >> between the footway >> and the road. > > There is! Ask the next wheelchair user or old man/woman with a walking frame > about the barrier a curb of normal height is for him. I agree that this part of our model is not very mature, and that it is always relative to the means of transportation if a barrier is preventing movement or not. Also in the case of dual carriageways you might physically be able in some cases / with some vehicles to change to the other way, even if not legally permitted. Still I keep the idea that sidewalks should be mapped in another way then independent footways, and this other way should not redefine highway=footway (i.e. use another tag). Any tagging of them with highway=footway is tagging for the routers/renders. cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
