Abstract
A method and device are provided concerning automatic reconstruction and evaluation of a traveled route, e.g., for offboard toll recording. In an embodiment, cost-effective onboard units, i.e., mobile telephony devices installed in a vehicle, are provided which record the position information, compress the recorded position information, and transmit the compressed position data to a main station. The main station is then able to reconstruct from the compressed position data the route a vehicle has actually traveled. An evaluation of the position information, e.g., for determining tolls, is carried out in a separate device. Since position data, digital maps and other operating data are now administered and processed in a central device, these data may be adapted in a simple and rapid manner, e.g., when updating the road geometries.

15. A method for automatic reconstruction and evaluation of a traveled route, comprising the following method steps:
-
recording continuously position information in a mobile position determination device; using a filter algorithm, significant positions are determined from the position information; transmitting the significant positions to a main station where a digital route map is stored; assigning every significant position to at least one route segment of the digital route map; selecting at least one route segment; reconstructing the driven route using the at least one route segment selected; and making available each route segment of the reconstructed route to an evaluation device for further analysis. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A device for automatic reconstruction and evaluation of a traveled route, comprising:
-
at least one mobile position determination device for acquiring position information;
a device for determining significant positions from acquired position information, using a filter algorithm;a transmission device for transmitting determined significant positions to a main station, the main station having a memory for storing at least one digital route map; a device, which assigns at least one route segment of the digital route map to each significant position; a selection device, which selects at least one route segment; and a route reconstruction device, which reconstructs the traveled route as a function of the at least one selected route segment; and an evaluation device for analyzing each route segment of the reconstructed route. - View Dependent Claims (23, 24, 25, 26, 27, 28)
