Abstract
A device, for determining road tolls having a road storage unit in which, in addition to a road network, parameters are electronically stored which represent a proportional toll due for each route section of the road network. A device for determining the vehicle position is provided, as well as a computer unit which determines the toll for a vehicle travelling over a particular route as least in dependence on the parameter and position data. An adaptation to changing tolls is possible in a simple matter with this device by storing new or further parameters influencing the toll.
