Do you have any UK examples of zebra crossings with traffic signals? From my understanding of UK traffic signs (which include road markings and signals), this seems rather unlikely. At a zebra crossing, vehicles must give precedence to pedestrians on the crossing. No traffic signals are necessary to stop traffic in order for pedestrians to cross. It may be the case that there are zebra crossings very close to a junction with traffic lights, but these are really separate entities and should be mapped as such. > a issue was closed in iD [2] some time ago because "the dev dislike > crossing_ref" (it is in fact a very ugly name for the tag) > right now josm [3] is changing preset to drop cossing_ref=zebra > in favor of crossing=zebra I agree with the ugliness of crossing_ref=zebra.
