Abstract: The video supervision on crossings is of great importance to the management of urban traffic. With the development of internet information technology, video supervisory system turns its steps to utilize the internet information platform to meet expeditious flexible requirements of traffic management. Thus, this paper studies several key technologies to internet information platform of video supervising of urban traffic. Firstly the video encoding technology is analyzed how to fit into traffic video supervision. The clustering computing platform is also elucidated to solve super computing issues. Then one of the mass-storage technology, SAN (Storage Area Network) is discussed to implement the storage and access of tremendous video data. Finally, on the basis of road traffic supervisory system in Hangzhou city, the platform has been implemented to prove its feasibility and efficiency.
