1. A method for generating toll information from movements of vehicle devices in a road-toll system that comprises at least one toll center and a plurality of connected, geographically distributed beacons for short-range radio communication with the vehicle devices, the method comprising:

  • providing, in a memory of a first beacon of the geographically distributed beacons, a first set of location data of one or more stationary toll-requiring geo-objects, other than the first beacon, in a local environment of said first beacon;

    providing, in the memory of the first beacon, a second location data set of one or more stationary toll-requiring geo-objects in a local environment of a second beacon of the geographically distributed beacons, the second location data set also stored in a memory of the second beacon and being different from the first location data set;

    recording, in a vehicle device, a sequence of position data of said vehicle device;

    when said vehicle device is in the transmitting/receiving range of said first beacon, receiving the first and second location-data sets from said first beacon in the vehicle device;

    comparing the position-data sequence with the received location-data sets in the vehicle device for geographical similarity to generate toll information therefrom; and

    when said vehicle device is in the transmitting/receiving range of the first beacon or the second beacon, transmitting the toll information from the vehicle device via the first beacon or the second beacon to the toll center.
