First impression: the value of the tag is extremely ambiguous, and in no way self-explanatory. I don't like it at all. > The first usage is putting highway=stop in the node where ways intersect: this > is not right, since that intersection represents (more-or-less) the center of > the junction, and I've never seen a stop sign in the middle of a junction ;-) I don't see a problem with this. As far as I'm concerned, highway=stop does not represent a particular stop *sign*, but rather the effect of the stop sign - i.e. the fact that vehicles must stop before proceeding through the intersecting node. > Consequent to this, I previously adopted the habit to put a highway=stop node > *before* the junction, on a separate node (on the same way, obviously), for > each of the streets having it. I don't like this, because "before" is arbitrary. If the stop requirement applies to the intersection, I think it should be applied to the intersection itself (either directly or as a member of a relation). Overall, I admire the attempt to avoid having a use a relation - but to convince me, the meaning of the tag must be self-explanatory. How about stop=at_last_node, stop=at_first_node and stop=at_first_and_last_node? More verbose, but a lot clearer than yes/-1/both. Also, I would remove the references to stop "signs" - replace with references to the requirement to stop - this is, after all, the characteristic of the way that is being tagged, not the fact that there is a sign near the way. In Australia, for example, I believe a stop "line" (solid white line) has the same legal effect as a stop "sign". _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
