Vehicle detection video through image processing: the Autoscope system

Abstract

Vehicle detection by video cameras is one of the most promising new technologies for wireless large-scale data collection and implementation of advanced traffic control and management schemes such as vehicle guidance/navigation. In this paper, recent worldwide developments concerning such detection systems are mentioned, and the one developed in the United States, Autoscope, is described. This includes earlier work leading to Autoscope's present state and its advan- tages over other emerging devices. Recent progress such as preproduc- tion line prototype development, field testing and plans for extensive field validation and verification are also presented. The latter include two large demonstration projects recently initiated in Minneapolis. In the first project, Autoscope will be used for incident detection over a section of Interstate 394. The second project involves implementation of the machine vision system at a signalized intersection.
