Abstract
A method of tolling vehicles in an open-road toll system with vehicle-based on-board units and roadside radio beacons. The method includes transmitting transaction information and a factor from the on-board unit; updating the factor as a function of the transmitted transaction information and calculating a debit amount as a function of the updated factor; transmitting a debit request with the calculated debit amount and the updated factor to the on-board unit; and debiting the received debit amount to a toll credit account in the on-board unit and writing a new transaction information concerning this new debit transaction and the received updated factor into the on-board unit.
