Abstract: High-definition video (HDV) technology is the development of the hot spots in the traffic detection field. The traffic integrated detecting system based on HDV is built in expressways for Beijing Olympic. It achieved on the complex monitoring of the expressway entrance and the exit, collection of traffic information and more business operations. This paper introduces the design and implementation of Traffic complex detecting system based on HDV in expressways for Beijing Olympic. It describes the overall situation of the system, designs the architecture, realizes the function modules, and analyses the information processing. Finally, it expounds the thinking of system integration from architecture, function modules, data Integration, innovation of application, etc.

Key words: high-definition video technology, Beijing Olympic, expressway entrances and exits, integrated detection, system integration
