Talk:Tag:cycleway=share busway
Shall we define rules about how Q/A tools or route calculators should handle data?
Simply put, if a way has cycleway=share_busway, a validation rule could be that it must have at least lanes:bus=* or busway=*. Asymmetric road layout might be a problem: when we have cycleway=share_busway and lanes:bus=2, it’s easy (every direction has a bus lane and cyclists should use it); cycleway=share_busway and lanes:bus:forward=1 should be understood as sharing the bus lane only in the forward direction, because there is no cycle lane in the opposite direction. (Or maybe we should enforce using cycleway:right=share_busway for clarity.)
Also, lanes:psv=* can be a substitute for lanes:bus=*, not to mention other possibly exotic situations (only taxis and cyclists, for instance). I fear that the number of possible valid combinations might become really high.
Does anyone have thoughts on this, or should we rather not bother too much? Bxl-forever (talk) 18:00, 19 December 2018 (UTC)
