Automatic toll ticketing system
First Claim
1. An automatic toll ticketing system for a roadway with vehicles thereon, the vehicles having an on-board apparatus with a first communication means, a vehicle transceiver, and an electronic purse in the form of a processor card capable of debiting a use toll while preserving anonymity of a user;
- at least one pay station on the roadway, the at least one pay station constructed and arranged to implement a data exchange with at least one wireless communication means attached at the roadway wherein the pay stations debit the use toll while preserving the anonymity of the user; and
a vehicle localization means operatively communicating with the at least one wireless communication means at the pay station, said vehicle localization means identifying a position of the vehicle, the vehicle communicating by outputting brief-duration optical signals by the vehicle transceiver without diminishing speed or stopping of the vehicle, a temporary identifier being known from a communication protocol allocated to the optical signal.

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.
