It would have to be ANY junction, I think (the nearest node that belongs to more than one way, as you say). There should be as little dependence on other tags as possible.

I thought that was what we were talking about already. Remember there's three options. 1) your description above, which John seems to like 2) http://wiki.openstreetmap.org/wiki/Key:stop 3) http://wiki.openstreetmap.org/wiki/Proposed_features/Relation:type%3Dstop _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
