Method for calculating driven distance
The driven distance of a travelling vehicle can be calculated by determining the used road network segments, which are e.g. road segments on highways. In this example a segment is roughly the road section between one highway entry and next highway exit. In order to determine the usage of the road, infrastructure based tolling systems comprise a road side gantry equipped with sensor or communication means (license plate number or on board communication unit, e.g. according to CEN DSRC standard) for detecting the vehicle on the road. In open tolling system architectures, this detector is located anywhere along one road segment. In the case that a vehicle travels along a route comprising more segments and one sensor/ communication device has failed detecting the vehicle properly, the road usage could be post‐calculated for the missing segment by the measured time between two correct detected vehicle passages and the average speed and/ or the maximum speed limits on this road. If the vehicle passes two detection gantries correctly, within a certain time period the vehicle must have used the missing segment in between, because any route around would take longer time.
