COMPRESSED VIDEO IN TRAFFIC MANAGEMENT: A COST EFFECTIVE APPROACH TO VISUAL SURVEILLANCE

The origin of image compression techniques lies in the U.S. Space Program, where video images of distant planets were transmitted over narrow band radio links. A video compression project has been ongoing in Dallas for the past four years. Funded by the Dallas District of the Texas Department of Transportation (TxDOT), this study has attempted to implement the latest video compression technologies as they come available as market products. The study was prompted by a previous study on slow scan television conducted by the Texas Transportation Institute in 1985. The Dallas study was implemented to explore the feasibility of using a dial-up telephone line to transmit compressed color video images. This paper describes the video compression process as it relates to traffic surveillance, and describes the equipment as well.
