Interesting! Since the data is on a node on the street way, how do we figure out if it's left/right side? kerb:left/right=*? Or do we figure it out spatially (find the driveway way and do some math)? On Sun, Jul 16, 2017, 1:14 PM marc marc wrote: > Le 16. 07. 17 à

My strategy in this kind of case is to add those driveways and virtual crossings that are useful for routing purposes. So if there is a junction, if there is a driveway opposite it, I will add that driveway (or maybe just the part of the driveway upto the sidewalk), if there is none, but people

If those two footways make up a reasonable continuing path, that's a good case for using the unmarked crossing tagging schema. It communicates all of the features actually being traversed (footway -> crossing the street -> footway) and is extensible: you can easily add curb and surface
