| The paper is based on the project of Jiangxi Science and Technology Agency"Research of Nanchang intelligent traffic management basic platform". The order of the building of many of our urban transportation systems mostly is the construction of the transport subsystem in more urgent need firstly and then the construction of a comprehensive transportation information platform, thus there must be producing an inevitable consequence of a heterogeneous data integration problem in the construction of the comprehensive transportation information platform. And this paper carried out relevant research on the Nanchang Comprehensive Transportation Information Platform based on CORBA architecture and XML data exchange technology.The thesis is divided into six chapters. The first chapter is research base which carry out thesis, and it talks about domestic and abroad for the thesis research, overview research on topics of significance and the technical support required. The second chapter based on detailed investigation, analysis and induction of Nanchang various intelligent transportation subsystems which have been put into practical use,provides basis in realty to the construction of Nanchang Comprehensive Transportation Information Platform framework and functional design architecture, and demonstrate its feasibility. The third chapter sets up Nanchang Comprehensive Transportation Information Platform framework, and divides into functional modules, which lays a foundation for the research and achievement of Nanchang Comprehensive Transportation Information Platform overall framework.The fourth chapter describes in detail Nanchang Comprehensive Transportation Information Platform information organization and information storage research, which lays a foundation for the research of Nanchang Comprehensive Transportation Information Platform data exchange technology. The fifth chapter on the basis of previous chapters designs Nanchang Comprehensive Transportation Information Platform based on CORBA architecture and XML data exchange technology, and partially achieves data sharing and exchange between Nanchang vehicle management systems and traffic accident systems. The sixth Chapter proposes full overview of research content and further study contents combined with the deeper project-researching.This thesis focuses on construction of Nanchang Comprehensive Transportation Information Platform from analysis and design of system to information organization study, then to the design and implementation of specific framework model. The result of this thesis has certain prospective and an important practical application value to Nanchang traffic information platform building and it is forward-looking has an important significance as reference to China large and medium cities to construct Comprehensive Transportation Information Platform on the basis of current situation. |
