    摘要: An electronic traffic tariff reception system can identify a vehicle traveling freely on a road having a plurality of lanes clearly and impose a predetermined debit value on the vehicle in the non-stop manner and in the cashless manner. Further, the system can photograph an image of an illegally passing vehicle. A vehicle identification apparatus can identify the vehicles traveling freely on the road having the plurality of lanes separately in a control point of the reception system. An in-vehicle unit equipped with a smart card is mounted in a vehicle. An antenna for debiting process capable of performing radio communication with the in-vehicle unit is provided. Also provided are an antenna controller for causing the antenna for the debiting process to receive personal information and vehicle information, a local controller for judging whether the information is normal or not or whether the vehicle is to be debited or not, and an apparatus for photographing an illegally passing vehicle. The in-vehicle unit is mounted in each of vehicles and at least one or more antennas are disposed above the road in association with each lane. When radio communication with the in-vehicle unit is made by way of the antennas, the antennas are started into a time sharing multiple accessing method.

    摘要: The object of the present invention is to accurately detect vehicles even under special conditions where vehicles go side by side, a motorcycle passes another vehicle in a traffic jam, or a shadow is cast on the road surface. The vehicle detecting system comprises a one dimension CCD camera 2 mounted above a road surface so as to provide one dimension light amount signal in the lane width direction from above the road surface and intermittent markings 6 disposed in the field of view of the one dimension CCD camera. When a vehicle 3 enters the field of view of the one dimension CCD camera 2, the modulation of one dimension light amount signal is disturbed. Therefore, a signal processing device 5 detects the vehicle on the basis of the output signal of the one dimension CCD camera 2 by checking the disturbance of modulation.
