Florian, Some of us have discussed what it might looks like to consider the "walking segment" as part of the shortest calculation - i.e. change the routing algorithm to: - consider all possible start points within 100m of the start coordinate (maybe 1m increments along the road) - co

Hi Florian, This sounds like more of a geocoding problem than a routing problem. OSRM itself doesn't know anything about addresses, it only works with coordinates and road geometry. All OSRM has internally are street names, not street numbers or place names. In order to route from "Münst

Florian, OSRM simply snaps the coordinate to the nearest road. If the back yard "streets" are part of the main road network (i.e. not `access=private`), then it's simply the closest road segment to your start point that gets used. Nominated is returning the building centroid for Münsterstra
