Dear all,

I would like to raise a discussion about possible options of how to 
tag/model sidewalks, crossings and kerbs with respect to routing 

As this can get quite complex, I have put some illustrating figures on 
this discussion page in the OSM Wiki:


Any feedback either via this list or directly on the discussion page is 

My current favourite would be either solution 3 (which is easiest to 
implement in current routing engines) or solution 1 (for the sake of 
actual correct modeling). Maybe there are even more (better?) solutions?
