Abstract:
A method comprises: disposing an on-board unit at a preset relative position with respect to a road-side unit; transmitting a signal by the road-side unit; receiving the signal by the on-board unit and detecting a strength of the received signal; calculating, by the on-board unit, a calculated strength of the received signal according to the detected strength of the received signal; storing the calculated strength of the received signal in a memory accessible by the on-board unit; using the stored calculated strength of the received signal to determine if payment of a toll should be made.
