ON-LINE VEHICLE CLASSIFICATION

For various applications it is useful to automatically divide vehicles passing a point into several categories. For the method described two inductive loop detectors were used in each lane. The shape of the bottom of a passing car can be assessed by examining the detector's analog signal. The passing vehicles can be separated into five categories: passenger car, delivery van, truck, truck-trailer, and truck-semitrailer. To investigate the effectiveness of the method, a "test set" of 950 signatures was gathered. By the use of the classifiers, an on-line program in assembler code was written for a PDP-11/20 minicomputer. The determination of the class can be carried out in approximately 500 mu s after a vehicle passes the detector. A trial with the on-line system gave satisfactory results.
