Dynamic Information Platform for Intelligent Transportation System

With the rapid development of intelligent transportation system and continuous increasing traffic flow, the information platform is the kernel and key to develop and construct ITS. The dynamic information platform is the goal of information platform development. From computer science perspective, it studies superincumbent three-tier management model which develops and constructs the collectivity structure scheme, main function and idiographic realization. It presents a multi-database integrated system architecture based on C/S combined with B/S. This architecture can solve the interlinkage problem of ITS and ensure to realize information collection, transmission, management and sharing. Adopted OLE DB and ODBC technologies can connect and read heterogeneous data, create data dictionary. XML is regarded as a public data model which eliminates the heterogeneity and multiple semantic relations of heterogeneous relation data, and realizes the heterogeneous data sharing and exchange. The dynamic information platform provides with the advantages of the effective integration and transport services.
