Abstract

This paper describes a diode-laser-based vehicle detector/classifier (VDC) presently being developed by Schwartz Electro-Optics (SEO) under an IVHS-IDEA program for the National Academy of Sciences. The VDC employs a scanning laser rangefinder to measure three- dimensional vehicle profiles that can be used for very accurate vehicle classification. The narrow laser beam width permits the detection of closely spaced vehicles moving at high speed; even a two-inch-wide tow bar can be detected. The VDC shows great promise for applications involving electronic toll collection from vehicles at freeway speeds, where very high detection and classification accuracy is mandatory.
