bkmap: It is not too late to change this. We must change about 11+2+7=20 tags worldwide if we consider to modify the notation of the lanes:*:tag. I'm strictly against global retagging. And it's impossible to unambigously resolve number of lanes to lane numbers in most of those cases.

Martin Koppenhoefer: how would the data consumer know, where the lanes are? E.g. a lane to turn left might also be right of the through-lanes, and this is crucial for routers to give good indications. Specially for data consumers and advanced mappers there is a section in the proposal

Hi! lanes:directions tag was bad, and I acknowledge that. Yesterday we finally chose a good alternative for it: lanes:X:location. It denotes the location of lane group for X. Self-evident example: lanes:merge:location=left. This tag removes some of mine doubts about the proposal, and I hope,

Hi! I've changed proposal a bit: now lanes:directions (still no good alternative to this tag, despite long discussion in russian forum) values are separated by commas, not semicolons: l,s,sr. This was done because a semicolon is used to enumerate simultaneous, not consequent, values (so

e.g. trunk_turnlanes:left:forward=1 meaning that from this point we have a left turning lane till the next intersection with a trunk highway ('forward' or 'backward' being relative to the osm way direction as usual). So, are you suggesting to use :forward/backward on nodes? I don't think that

The tag lanes should be reserved for the straight forward lanes. At a T-junction, the road ending there would then be lanes=0, given that wording. Nice. As a result, we just add a node for a minor information and do not damage the existing highways. There's bound to be, eventually, enormous
