METHOD AND APPARATUS FOR THE REGISTRATION OF A VEHICLE(S) IN A FREE FLOW TOLL FACILITY BY TRACKING THE VEHICLE ALONG A PATH IN THE TOLL FACILITY AREA

A method registers a vehicle in a road toll facility that is provided with radio transmitter and receiver units (7). The radio transmitter and receiver units are configured to communicate with at least one vehicle unit (12) arranged in the vehicle (4). The vehicle unit is configured with radio transmitter-receiver equipment so that on receipt of a command from the radio transmitter unit (7) of the road toll facility, the vehicle unit communicates adequate data for performance of a debiting operation regarding a toll. Upon the entry of the vehicle into the toll facility area, the transmitter and receiver units (7) of the toll facility determine whether the vehicle (4) is equipped with a vehicle unit capable of performing a correct debiting transaction. The method distinguishes between vehicles for which the correct debiting can be performed and vehicles for which no debiting can be performed, and establishes a position for the vehicle by subjecting the vehicle to successive position measurements, and tracks the vehicle to a predetermined position where the license plate or other identifying characteristics of the vehicle that did not properly carry out a debiting operation is recorded for postdebiting of the toll.
