RADIO BEACON FOR A WIRELESS ROAD TOLL SYSTEM
A radio beacon for a wireless road toll system including a transceiver, which is arranged for packet-type radio communication with onboard units of passing vehicles; at least one camera for recording an image of a passing object; and a control device connecting to the transceiver and the camera. The control device is configured to measure, in conjunction with the transceiver, the number of data packets received per unit time from a specific onboard unit and to actuate the camera to record an image of the object carrying this onboard unit, in the case of a number exceeding a threshold value.
