I have installed an own instance of OSRM (latest version 5.18.0). I used latest osm data (bremen.osm.pbf) with the original car.lua script.
When testing, there is a routing error. You can see the same error in the demo map of OSRM:
It shoudnt route via this way (“Johanne-Kippenberg-Weg”) because it is for pedestrians / bicycles only. In osm it is defined as “highway=path”, you can see it here:
I am struggling a lot to understand all those attributes in osm-data, (and tags / black/-whitelists in the lua script).
My question in this case is
1.) Why is it routing via “Johanne-Kippenberg-Weg” although it is not defined as a motorway?
2.) What is the right approach to fix this error in my application. Edit the car.lua (if so, in which way?) or edit “Johanne-Kippenberg-Weg” in OSM-data (if so, in which way?)?
Thank you for your time!
