[Tagging] Feature Proposal - RFC - Turn Lanes

2011-10-06 Thread Ilya Zverev
Hi! Following discussions in this list and in couple of forum threads (and since there are some eager nav software programmers that wish to use the first proposal they see), I studied all of the proposals for tagging turn lanes and made a compound tagging scheme, which is not hard to use, but

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

Hi. Some remarks have been mentioned here already, why this proposal is not well designed. Another one is, that it's tackling the lanes-problem, but not solving it. You propose something for turning lanes - but again restrict it to cars. The talk page in the wiki contains a question about
