The vehicle detector and classifier (VDAC) uses a scanning laser rangefinder to measure three-dimensional vehicle profiles that can be used for accurate vehicle classification. The narrow laser beam width permits the detection of closely spaced vehicles moving at high speed. The VDAC shows great promise for applications involving electronic toll collection from vehicle at freeway speeds, where very high detection and classification accuracy is mandatory. Several major ITS companies have expressed a desire to purchase VDACs when they become available for electronic toll and traffic management applications.
