If they are in a residential area with sidewalks, then the sidewalks and their junctions with the roads are mappable. And then you will be able to get within a 1/2 block of the location with error free routing. If it is a very long road with a sidewalk on one side, driveways that intersect will share a node with the sidewalk and with the road, and can be used for the last 100m of routing, or a suggestion to cross the street in a safe location if there is no shared node between the road and the sidewalk for 50-100m around the destination on the other side of the street. If there is no sidewalk, then we are just mapping the road or a rough *highway=trail* unsuitable for wheelchairs or kids on bikes (now that highway=path is hopelessly confused with other tags in some regions [like Japan] - another thing that adds to this giant mess) to indicate that there is no proper sidewalk (and like almost all residential roads in Japan) you will be traveling in the road to your destination. If we want very accurate pedestrian routing with kerb slope and tactile paving tags, we need very accurate separate sidewalk and driveway mapping. Otherwise the routing is very similar to car or cycle mapping. Perhaps we need a highway=kerb_cut that is mappable or barrier=kerb_cut to map the extent (way) or intersection with a footpath (node) of where the sidewalk ends and crossings (a unlabeled crossing or a controlled marked one) begins . Barrier=kerb can be put on a footpath without cuts where it meets a road but has no cuts (common) as a barrier for cyclists and wheelchairs. Barrier=* has several different "openings" in the barriers. Having curb cut might be a good addition of we are going to be mapping kerb as ways on the road - mapping the long cuts for pedestrian crossings (and eventually driveways and other places where the curb is sloped to allow vehicle access.) I think Barrier kerb should default access to motive heckle=no foot=yes bicycle=dismount and wheelchair=no Javbw. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
