I like the idea of that, but think it might be better if the member ways had roles like 'stop' or 'give_way'. I know several intersections which have both Stop and Give Way signs, so being able to use a single flow-control relation to represent both of them would be nice. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

There's two acceptable approaches to dealing with this: 1) use a relation to relate the way and intersection - for this, I see nothing wrong with http://wiki.openstreetmap.org/wiki/Proposed_features/Relation:type%3Dstop or 2) use a way and an implicit reference to a node to relate the way and intersection - this is what David is proposing here: http://wiki.openstreetmap.org/wiki/Key:stop The implicit reference to a node is in the form of at_first_node/at_last_node, etc. Using a relation has some advantages: * it connects the stop requirement to the junction node (you can look at the junction node to see that there is a stop requirement) * if the way leading to the junction is split/reversed, the relation still works (although it will have two way members, so it's slightly broken) With the current editors, it's not hard to add relations, and a stop relation is almost self evident how it works when viewing it, but the tags proposed for the way needs to be looked up to be understandable. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Yep. On the other hand, tagging a way has an advantage: it avoids the need to add a relation. What is everyone's preference?
