Oneways are easy. Two-way situations like http://binged.it/Kj5IFM = http://www.openstreetmap.org/browse/node/1239065241 are awkward to interpret. It's intended for westbound traffic turning onto the major road, not eastbound traffic turning onto the residential street. In this case however, you just need to look for the nearest traffic signals node to figure out which is the correct orientation for the ASL. It can't be done by simple junction proximity in this case, however routers using ASL nodes could discard ASLs encountered within short distances of traffic light intersections in directions facing away from the traffic lights. Major-onto-minor road intersection could be another way of managing routing discards for particular directions. The ASL faces in the direction of the most major intersection node if there are two adjacent candidate intersections. Feels intuitive, but fragile :/ (Having a highway=stop node positioned behind the cycleway=<x>stop actually makes things easier for both when interpreting direction. The clue is in the "advanced" :-) -- Andrew Chadwick _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
