[OSM-talk] Cycleways and Access tags: Left, Right, Forward, Backward?

[rob.j.nickerson at gmail.com]

Arg, thats still not right is it? Firstly it leaves 2 values for  
cycleway:left and also the opposite_track is not quite right because if it  
had been on the right hand side of the way (but the way was still  
orientated in the same direction) you would have to use  
cycleway:right=opposite_track to imply that the cycle track flows in the  
same direction of the traffic closest to it (ie the traffic on the right  
that is going in the opposite direction of how the way is drawn).

Maybe it should be "The track may be cycled in the opposite direction of  
other traffic using the same side (ie right / left) of the road"

Finally the talk page has a good suggestion to use  
cylceway:left=bidirectional_track but this has no uses according to tag  
info.
