Patent ID: 8255272

Claim:
A test method for optimizing a toll collection obligation for vehicles on toll roads of a road network, comprising: providing a vehicle-mounted position determining unit; providing a vehicle-external management unit connected to the vehicle-mounted position determining unit for data communication; detecting vehicles on the toll roads subject to a toll collection obligation by: overlaying the toll roads of the road network in an electronic image of the road network by detection zones having a predefined coverage area; determining by the vehicle-mounted position determining unit toll-related data based upon position data lying within the detection zone of the vehicle-mounted position determining unit; sending the toll-related data from the vehicle-mounted position determining unit to the management unit; detecting vehicles on the toll roads but not detected in the detection zones by: providing monitoring zones in the electronic image of the road network, wherein the monitoring zones are assigned to detection zones, wherein the monitoring zones extend in their spatial extension beyond the predefined coverage area of the detection zone; determining by the vehicle-mounted position determining unit journeys exclusively within the monitoring zone and outside the detection zone, wherein the position determining unit sends the position data of the journeys to the management unit; checking the position data of the journeys exclusively within the monitoring zone and outside the detection zone by the management unit; and determining that the journeys should also be subject to the toll collection obligation.
