The Design Of Communication Platform Of City Transportation Information System

Intelligent Transportation System (ITS) manages and controls traffic resources more effectively to improve the flexibility and security of traffic with the application of communication technology, artificial intelligence technology, and computer technology. ITS is the future direction of traffic development in China. As the technical carrier of traffic information's collection transmission storage dispose manage and release, the Transportation Information System is the data center of ITS which can make the exchange and management of data orderly and effective.This paper comes into being on the above-mentioned situations. According to the realistic situation of current traffic development, first of all, the paper analyzes the system requirement and design. Then, it roundly analyzes and researches the system function request architecture key technique of information release and transmission. After one year's research and test, I draw some conclusions as following:1. Design the project of the system about "the transportation information system". Raise the way to realize releasing system.2. Complete building the web by using ASP and ADO technique.3. Design the project of data transmission by SCA channel between center and terminal. Complete the transmission test in the lab.The method raised in this paper is relatively new, and has a high practicality. The design of communication flat raised in this paper incarnates the using of communication technique in the transportation system, which have meaning in theory and practice.
