I can't really see a difference between "bicycle=no" and "bicycle=dismount" to be honest, although it seems to me a naive router would distinguish them.
The more I think about the whole bicycle/footpath thing, at least in the Australian context, the more I conclude: 1) There are very *paths where bikes are really forbidden, and extremely few *paths where walking is forbidden. 2) What cyclists who use maps really want to know is "how good is this path for riding" and "can I follow this *path somewhere useful?" - is it signed for example 3) What pedestrians who use maps really want to know is "are there any major physical obstructions between me and my destination" and "can I follow this *path somewhere useful?" 4) Structuring everything in terms of legalities, which few people are actually aware of, doesn't make much sense in the Australian context. In terms of 2), there are maybe four categories: 1) High quality bike paths: wide, smooth asphalt, gentle corners, no kerbs. 2) Lower quality paths: concrete, or narrow, or with bumps and kerbs and stuff 3) Unsealed paths. 4) Paths that bikes are banned from. And of course there are signed routes, which can include on-road sections. They're nice to know about. That's all you care about. Maybe it's nice to tag every detail like the precise width of the road. But if you just had the information I described, you'd be a happy cyclist. The reason cyclists are not happy atm is that generally category 1 is tagged "cycleway" and categories 2-4 are tagged "footway" - or at least render that way. Whereas if you had to split them between two categories, you'd group 1-3 as cycleway, and 4 as footway. That's my analysis for the night. Steve
