ABSTRACT:
A tunnel monitoring system for monitoring vehicles traveling through a tunnel having at least one vehicle traffic lane is disclosed comprising a plurality of ultrasonic sensors arranged in series in a longitudinal direction of the tunnel. The sensors have a detection zone covering a portion of the traffic lane for detecting the presence of a vehicle in the detection zone, and the ultrasonic sensors generate a vehicle sensor signal upon detecting a vehicle in the detection zone and a sensor identification signal identifying which sensor the sensor signal is transmitted from. The detection zones are projected and arranged in relation to the traffic lane to provide a generally continuous detection of the vehicles traveling though the tunnel. An evaluation unit receives the vehicle sensor signals and the sensor identification signals for monitoring traffic in the tunnel.
