Assuming that you meet the "certain circumstances", I see little practical difference between "You can't cycle on the road" and "you must use the cycleway and not the road" in terms of whether or not you are allowed to cycle along the road. Granted, crossing and turning may be slightly different, but for general riding along a stretch of road the effect will be the same -- you can't ride there. However, these slight differences are why I suggested using bicycle=restricted for when the prohibition caused by the presence of a parallel cycleway isn't so absolute. Doing this would seem to be perfectly correct -- cycling on the road is indeed restricted. Doing it this way (rather than a single tag) has the advantage of using a more general value on the access tag (that is thus more likely to be interpreted in an appropriate fashion by more routers), while still allowing (encouraging even) a more specific tag to capture the precise detail of exactly what the (country-specific) restrictions are. We then don't confuse the effect of the legal restrictions with the cause of the restrictions. By encouraging mappers to specify the precise source of the restrictions in a separate tag, we're less likely to get mappers using a bicycle=use_cycleway style tag inappropriately due to misunderstandings, and should end up with better-defined tags and more accurate data. -- Robert Whittaker _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
