Informationization is the aim of China's modern urban transportation. Information sharing platform technically ensures that various subsystems work in a coordinated manner, as it helps facilitate information sharing, enhance efficiency, improve the operational environment and optimize the entire transportation system.The paper first analyses the main problems in the information utilizing of the urban traffic information system based on the development of transportation systems in large Chinese cities, separated traffic information, lacking uniform management, lacking criterion, information islands phenomenon, bad coordination and relation between application systems and so on. Accord to this problems, it brings forward the theory of establishing the traffic information sharing platform to coordinate the traffic systems effectively and realize the traffic information sharing adequately to some extent. The it gives a user analysis, user information demand analysis, function demand analysis and the content of the information sharing platform. It then puts forward the structure of this platform in light of status and the function of the information sharing platform in the traffic system and the demands of different clients. At the same time, it dwells upon the logical framework, physical framework and interface structure of the platform. In the process of information analysis, storage and processing is the key of the information sharing platform construction, and it is the precondition and guarantee of the traffic information can be shared and utilizing. The paper puts forward the information storing system that information are stored separated in physics but centralized in logic, and then it gives particular design. In particular, it comes up with a detailed design of the information collection, information exchange, information processing and information integrating. However, information exchange is always the crucial tache in the information processing, which is deemed as a crucial part of the platform. Based on the analysis of the data exchange types and the development of the XML, the paper puts forward that take the XML as the data exchange technology to accomplish the information exchange between the mainstream relation databases, and then it gives a data exchange project based on XML, to solve the data exchange problems between different platforms and heterogeneous data.The structure of the information platform discussed in the paper provides a whole framework to the urban information platform, and provides powerful data background...
