Design And Implementation Of The Function Of Synthesized Information Service System

With China's sustained rapid economic development, deepening the process of urbanization, urban traffic management is an important problem which restricts the economic development and improved living standards. For traffic manager, it need to be solved pressingly that How to use advanced communications and information technology to improve the level of the city's traffic management, to allocate public transport actors reasonably, to ensure the public transport priority, to provide efficient transport service.With 3G licenses, large state-owned telecom companies need to solve that how to achieve sound and rapid growth of new businesses by combining the advanced communications technology and industry needs.The purpose of this research is to design a typical solution for the practical application of 3G technology for intelligent transportation system.Specifically:1. Briefly introduce the background of the construction of intelligent transportation system;2. A comprehensive analysis of user needs intelligent system bus;3. Introduce the principle of VPDN;4. According to network design and platform design, give the overall solution of intelligent public transport;The research projects provide a practical way for the establishment of 3G technology in public transportation industry solution.
