In Belgium (and other European countries), it is illegal to cross a solid white line under normal circumstances. An OSM way represents a separate street, not a lane. When you start representing lanes as ways, you break data consumers that count ways, or that really need to know whether the physical divider is. Emergency vehicles are not interested in solid white lines, but are interested in physical dividers that they cannot cross. For all those reasons, I will not map a separate way for a lane separated by a solid line. I do hope that the but routing apps should start implementing change:lane, which is the proper way to map it IMHO. regards m (*) in some special case _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
