Mostly "we" are interested in the result, not the signs. It's the traffic code's limitation, that their best option is to forbid the turn, but the result is the same: generally nobody may use the u-turn connector, but emergency vehicles can. As for overloading, is there an imaginable case where a way tagged highway=* acts as an emergency=fire_hydrant, or any of the other values listed? Afair, the key emergency was first used as an access group, and the "emergency facilities" were only later grouped under a single key. >access=emergency "Emergency vehicles" are a "by use" category - as the Key:access page refers to them. It's better as a key. Here some effectively pedestrian ways into apartment building yards are signposted as a (literally) "rescue road" - that's emergency=designated. It doesn't by itself stop anyone else using it when they need to haul something heavy, but the signs make it clear to anybody that parking there will block the fire engine/ladder car from reaching some houses. (There's a no parking icon included in the traffic sign to make it understandable even for foreigners). -- Alv _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
