+1 to all of this. If we want to be able to distinguish physical and legal separations we have to stick to our own rules. Anyway there will always remain a slightly unsatisfactory geometry situation on points like these, because you have to do the transition from 1 way (in the middle of 4 lanes) to 2 ways (each in the middle of 2 lanes). There is simply no really elegant way to do this. Additionally to the lanes=4 and oneway=yes you could put a divider-tag on the way http://wiki.openstreetmap.org/wiki/Proposed_features/Divider even if it doesn't explicitly tell you where the divider is placed you might be able to infer it from the following ways (at least in this case). cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
