Abstract
A method for detecting vehicles includes two ultrasonic overhead detectors arranged along a lane or path of travel of a car through an access gate or entrance. The detectors measure the heights of the hood, roof and trunk of the car as it moves past the detectors. Software is used to compare the measured quantities with pre-established vehicle profiles. The method, and the associated hardware and software, can be used to count vehicles, classify vehicles as well as operate peripheral devices such as traffic lights, gates and the like.
