Abstract (en)
A system for the automatic detection of moving vehicles, with data exchange, particularly with automatic toll charging, comprising a fixed receiving and transmitting station capable of communicating with a plurality of on-board transceiver units (3) each of which is associated with one vehicle. To avoid confinement to a single-carriageway transit lane of vehicles passing the transceiver station, the invention specifies that the transceiver station is provided with a plurality of aerials (A.1-A.n), each of which forms a coverage area (C.1-C.n) of dimensions considerably smaller than the dimensions of the vehicles, so that only one vehicle can pass through each coverage area at one time and consequently only one on-board unit (3) can communicate with each aerial (A.1-A.n) at one time, while the signals received by each aerial (A.1-A.n) are processed separately from each other. The invention also specifies a particular method of application. <IMAGE>
