• Aktuell ist OSM ist für Rad-Routing in den Städten nicht arg hilfreich / users: Germany / OpenStreetMap Forum

  separat kartierte Radwege sind ein Problem

  Es ist mächtig kompliziert zu beachten dass diese Wege eigentlich an großen Verkehrstraßen laufen und 1000 Einmündungen kreuzen. Aus den Tags des Weges allein kann man nicht wissen dass dieser parallel zu einer richtig dicken highway=primary etc ist. Diese Wege sehen in erster Linie nicht anders aus als ein schöner isolierter Radweg im Park oder am Fluss entlang.

  • is_sidepath very low usage (taginfo), without highway classification (no uses of is_side_path_of)

• Java-Bibliotheken für Routing gesucht / users: Germany / OpenStreetMap Forum

  Umgebung/POIs, z.B. "im Wald", "am Wasser entlang", Aussichtspunkte
