Penalties
See the global page on routing penalites.
Routing penalties for road types Off-road and Parking Lot Road and also the checked segment attribute Unpaved may each result in a penalty of approximately one hour. The penalty for Private road was, during a test some time ago, the double. These durations may have changed in the mean time. The penalties for Parking Lot Road and Private road are applied when transfering to another road type, not when entering.
