So it appears the letter designations are stand-ins for the name or the ref or more specifically the name as it appears on signage. It could be the name of a city for example. I am having trouble relating it to width, but I think the width:lanes:start/end formulation could cover it. > > Also, I often see a center lane for left turns in both directions, as in > https://ecn.t0.tiles.virtualearth.net/tiles/a0213330110033323031.jpeg?g=6570 > That's next on my list.

My first take: lanes=3 lanes:forward=2 lanes:backward=2 turn:lanes:forward=left|through turn:lanes:backward=left|through lanes:forward/backward might possibly be redundant. I think of it as a suicide lane, and it might confuse JOSM's "Enhanced lane and road attributes" even more than it does me. Well there is at least one way to find out. -- Tom Hardy <rhardy...@gmail.com> _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
