The Design of Traffic Management Information System Based on VR JU Xin-gang1, Ma Hai-jun2 , Wu Bing2 (1, Circuits and Systems Key Principal of Henan education institute, Zhengzhou, 450052,China;2, Air Defense Forces Command Academy, Zhengzhou,450014,China) [Abstract ] The design of traffic management information system（TMIS）plays an important role in traffic management, scientificalness and efficiency of policy-making. Accompany with the development of 3S, VR technologies, the capability of data management and space analysis is getting more powerful than ever. Also we can find that it is a efficiency solution to provide traffic management and decision support by construct a traffic management information system with reasonable structure and accurate data. Through TMIS, we can get an elaborate description of current highway grid and get a scientific conclusion and evaluate. Combine with GIS and scene simulation technologies, this paper gives the general flow, method of modeling TMIS and designs the module and function of it. In the end, it points out the foreground and methods of improve the system performance.
