Abstract
Vehicles having an on-board device further have a communication device, a vehicle transceiver and an electronic purse in the form of a processor card. Pay stations are arranged at locations along a roadway. The pay stations implement a data exchange with a wireless communication device and debiting a use toll. A vehicle localization device is provided in addition to a communication device at the pay station. The vehicle localization device identifies the position of the vehicle just arriving based on a brief-duration optical signal output by the vehicle transceiver wherein the temporary identifier known from the communication protocol is allocated to the optical signal. The optical signal can be an infrared photoflash that is output on demand by the pay station. The vehicle localization device is an infrared-sensitive video camera that identifies the position based on the optical imaging of this vehicle with computer-controlled evaluation.
