ABSTRACT:
The toll collecting system includes a first detector and a second detector which are sequentially arranged in the moving direction of vehicles passing on the traffic lane for collecting charges and detect a passing first vehicle and a second vehicle moving behind the first vehicle respectively, a roadside antenna and an antenna controller for carrying out radio communication between the detector and the first vehicle passing on the traffic lane and between the detector and the second vehicle respectively and obtaining information such as a vehicle kind and a vehicle number, a camera for taking a photograph of the number plate of each vehicle on the traffic lane, and an image processor for obtaining vehicle information of the second vehicle from the number plate of the second vehicle photographed by the camera when the first detector judges the number of passing vehicles of the first vehicle as two vehicles and the second detector judges the number of passing vehicles of the first vehicle as one vehicle. The system compares the vehicle information obtained by the image processor with the vehicle information obtained by the antenna controller and recognizes the second vehicle of the first vehicle which is detected as two vehicles by the first detection means as a misread car when both types of information coincide with each other.
