Abstract: Intelligent Transportation Systems (ITS) have become one of world-wide hotspot as the economy developed. Video-based traffic flow parameters detection system has several apparent advantages such as easily intervened and lower costs. So it should be used in the future. This paper presents video-based vehicle detection technique which is applied to ITS, and introduces some techniques used in video-based vehicle detection and the main detection parameters. It also analyzes the elements which affect the detection precision and strategies which enhance the detection precision.

Keywords: Intelligent Transportation Systems; video-based vehicle detection; traffic flow parameters detection; image processing
