As a co-developer of mkgmap, a software that convert OSM data to Garmin map format, I've looked at this problem quite often now. I think routing itself is not the big problem here, unless we talk about the additional resources needed for the additional ways and junctions.
Both tagging schemes have pros and cons, none is making it easy for the mapper when it comes to map complex crossings. Still, I tend to think that the mapping of extra ways for the sidewalks is the solution that requires less training and less "abstraction capabilities". One of the problems that is not well solved is the switch between both tagging schemes. When I start to draw extra ways for the sidewalk, where do i stop this and how do I connect the sidewalk with the main road?

The problem with separate ways, is that none of the current routers will tell you that you have to cross the street to reach a house on the other side of the road. Most likely, they will let you walk till the next street crossing and let you walk back then. There are some proposals to solve this problem, but no implementation so far AFAIK. Try cycle routing on osm.org in an area with a lot of separate cycleways (e.g. The Netherlands) and you'll see what I mean. regards m _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
