ABSTRACT:
A system and a method for detecting vehicle types utilizing height information and a debiting system using such a system or a method. A plurality of distance sensors (heads) are provided laterally on a road, and 0/1 linked existence data and linked height data are generated by a link generator. The former data represent the existence of a vehicle on a detection line drawn along the road width direction on the basis of the distance data obtained by the heads and the latter data represent height profiles of a vehicle on the detection line. Height data such as maximum, minimum and average height in every height block are calculated by a scan-by-scan height evaluator 38 on the basis of the linked height data and vehicle position information, and a vehicle type detector 40 detects the type of the vehicle. It is possible to accurately detect illegal vehicles, which have an ID corresponding to another vehicle type, by transmitting the results to the host system together with the output of a vehicle detector and using a detection result.
