DESCRIPTION:

BRIEF SUMMARY
The invention relates to a method and a system for determining user fees for traffic routes and/or traffic areas.
Various methods have become known for collecting user fees (tolls) for traffic routes, in particular roads. However, up to now only toll stations, where vehicles stop and are permitted to use the road subject to fees after having paid the toll, have found general use. In spite of a plurality of individual toll booths, this leads to traffic jams on high-density roads. Even devices wherein a coin is tossed into a funnel while moving slowly provide only limited relief.
In addition to this, methods for the automatic determination and debiting of user fees have become known. In connection with the method described in NTZ, vol. 46 (1993), issue 4, "Zukunftige automatische Gebuhrenerfassung Traffic!, collecting stations are equipped with devices wherein communication takes place between the collecting point and the vehicle. For this reason monitoring of payment must take place directly during the passage past the collecting point, most often designed as a bridge. Communication is furthermore only possible within locally limited zones in order to assure unambiguity between the communicants and the vehicle detected by a camera. Furthermore, it is not possible because of the limited communication times to apply the security procedures in connection with electronic money transfer, common in the banking and credit industry. In addition, all vehicles must be equipped with terminal devices capable of communication in order to be able to pass by the monitor cameras, so that they will not be recorded and considered to be non-payers.
A considerable outlay for collecting stations and a limited communications time also occur with such systems even if the calculation of the fees takes place in the vehicle, as in WO 91/18354. pages 2 to 3, utilizes a detection of the position of the vehicle with the aid of the GPS system (global positioning system), by means of which a position detection by satellite is performed. With this, only virtual collecting stations are required, so that the outlay for suitable buildings can be omitted. Control of the respective debit is based on a combination consisting of a beacon system and a camera. The steps relating to security of the money transfer occur exclusively and locally in the vehicle. Since the charging of fees only takes place in the vehicle, it is not possible to provide indexing of the fee structure based on the traffic. Just as in the first described method, a control is only possible during the limited connection time between the controlling vehicle and a fixed station.
Also, all vehicles must be equipped with electronic devices for passing over a toll road section.
A vehicle control and target-guidance system known from WO 92/10824 can be used for toll payments in that beacons are used for location determination for a fee calculation taking place in connection with the vehicle. As in a system known from GB 22 48 957 A, the fees are then debited to an account card. Since the calculation takes place only in the vehicle, the indexing of the fee structure in accordance with the traffic is not possible.
It is the object of the instant invention to suggest a method for determining the user fees for traffic routes, which operates with a small outlay in respect to stationary devices, and wherein an assured transfer of the respectively determined user fees is possible until they are debited to an account or a credit account of the user.
This object is attained in accordance with the invention in that user fees are calculated on the basis of position data and fee data and transferred to a central point via a data transmission system. The method in accordance with the invention has the advantage that it is possible to utilize a basically existing infrastructure, such as the GPS system and digital mobile radio networks. In connection with the method of the invention it is furthermore advantageous that sufficient time is available for transmitting the user fees, so that all measure
