I always assumed the intersection *was* the two or more ways intersecting, but this is being pedantic. > > Here, State law holds that you stop directly *at* a stop > > sign (usually > > How many stop signs are in the middle of intersections?

It's not a normal traffic light. It is legally and practically treated the same as a stop sign. My state describes it as "This sign is used at intersections when a stop sign alone is hard to see or where additional emphasis on the stop sign is needed." I would tag it as a stop sign, I only mention it as a legitimate case of a stop being in the middle of the intersection. > > intersection.

True, I agree about the simplicity of just using nodes, that email was more directed towards http://wiki.openstreetmap.org/wiki/Key:stop -like proposals with tags like stop=at_first_and_last_node. -- Joseph Booker
