I've pondered this without conclusion, yet. Unfortunately it's a bit complicated, since length and width of vehicle, width of barrier and width of path all come into play.
You could probably calculate it for "standard" bikes by drawing a ?0.7m straight path through the barrier and then calculating the degrees of deviation from straight that requires. But that's a bit fiddly and doesn't really help you for non-standard bikes. Maybe: barrier:bicycle=feet-up (for ones where with practice you can get through without putting your feet down) barrier:bicycle=feet-down (for ones where you have to put your feet down but don't have to lift and move wheels sideways) barrier:bicycle=wheel-up (for ones where you have to lift and move wheels sideways) barrier:bicycle=dismount (for ones where you have to dismount) barrier:bicycle=bike-up (for ones where the bike has to be lifted completely) barrier:bicycle=no (for ones where bicycles can't get through at all) with similar for tandem and bicycle_trailer Richard On Tue, Dec 3, 2013 at 9:44 AM, Volker Schmidt <[email protected]> wrote: > > Here in Italy we have plenty of bicycle barriers or chicanes ( > https://wiki.openstreetmap.org/wiki/Barrier_examples), often with more > than 2 inverted-U-shaped bars to make life even more difficult. > They are used to prevent motorcycles from using cycle paths (not as in > Germany to prevent bicycles from using footpaths). > As these are serious obstacles for cyclists I have started tagging them > more precisely with, for example: > bicycle=yes/dismount > wheelchair=yes/no > max_width=xxx > The latter is not correct as "max_width" indicates a legal requirement, > normally a road sign, giving the maximum width of the vehicles that may > pass the obstacle or road. > Should I use "width" or "est_width" which normally indicates the width of > a way?
