I read that the simplest process that works in using multiple vehicle profiles (car ,foot , hike) is to download an osm/pbf file from Geofabrik and modify the config properties, in order to produce a graph with CH off and the vehicles you wish. Then I can load the produced graph and play with it by using the proper vehicle.
The thing is that I couldn't understand how I can modify the config properties and where?
please any help
