It does require a relation (e.g. the proposed type=area) to indicate that there is not dual carriageways but only lanes (and of course for compatibility no highway-tag on the lanes), so that you might be able to change any time (or also not if there is an uninterrupted marking). So it might be more work to create this but I think it will be more stable and easier to maintain afterwards. > But you are right, drawing intersections like here is a nightmare and > is not reflecting the reality : the intersection is only a square > where lanes are not painted on the ground.

A highway-polygon is representing an area without traffic direction. If there is a direction, use a way. cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
