Re: [OSM-talk] How do you tag a traffic signal that's also a motorway junction?

I would tag the ways as usual, highway=secondary or whatever is appropriate here. highway=traffic_signals ref=10B If that is indeed a flare for the right turn to 657 Eastbound, I might mark the first node of the flare with the ref=10B The ref doesn't mean anything without an associated tag though. motorway_junction is the accepted way to show a numbered exit, even if it isn't attached to a motorway. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

highway=motorway_junction with ref=[number] is used whenever there's an exit/junction number, whether or not it's actually on a motorway.

If this were a motorway_junction (it isn't) the exit number would be in the ref tag on the exit node, so go with that. In the US, no; highway=motorways can't have level crossings. But, despite the name, http://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway_junction is not only for use on motorways. (And renaming it wouldn't help; it would then be a question of how to tag the same node as both traffic_signals and trunk_junction.) I would tag the ways as usual, highway=secondary or whatever is appropriate here. highway=traffic_signals ref=10B To expand on Ian's reply, the ref for an exit number only makes sense when coupled with highway=motorway_junction; some cities number their traffic lights and post these numbers: http://www.flickr.com/photos/jstephenconn/2961191591/ This is what I'd expect from highway=traffic_signals ref=3.
