A Traffic Analysis System Based On Web GIS

Because the work of traffic analysis is weak, so a traffic analysis support system based on Web GIS is designed to clear up the situation that the information of traffic analysis is not adequate to satisfy the road management.Combined with the technology of traffic analysis and the successful application of Web GIS, in the views of theory and practice of engineering the Web GIS-based traffic analysis System is discussed and researched in this paper.Firstly the theory and technology related with traffic analysis is discussed in this paper, and the development trend of traffic analysis technology now, in order to support the system in theory. Then combined with the function and technology of Web GIS, the application of Web GIS in the system of traffic analysis is discussed.Next, this paper discusses the research work of Web GIS-based traffic analysis support system. Here, the system structure, dataflow and soft structure is discussed. The subsystems of the real time acceptance of traffic data and data management and map data released based on Web GIS and map handled and data analysis are introduced, through which the system integrates different function and make the research and display easily and visually.Last, according to the idea of software engineering, the collectivity design of Web GIS was presented in four aspects: the system framework, the network construct, the communicating flow and the function module.
