Abstract: In the speech, be analysed the benefits that the Intelligent Traffic System should produce at first. He also analysed the benefits after Japan carried out the automatical charge system taking ITS charge system as an instance, and the effect that Japan achieved in the aspect of VICS system, meanwhile, in Europe and U.S.A. ITS is not so successful, which is refared to the operation way and social habit, Secondly, he spoken of the changed that informationization caused on traffic manage. Because the information of traffic vessel is all one-way function, as operators, they consider the question according to the network and capacity request and make the time table of running, as for the passenger and cargo owners, they must arrange their going out and transporting. We are already entered an ITS times, and we should arrange the network according to the user’s needs and the impact on the whole management, this are the changes that madern technology brings. Thirdly, he spoke of how ITS capable of saving investment. He showed the full-screen information boards of Beijing second ring road and third ring road cost much more money, and there is an idea of making the investment sparingly in Shanghai which is thought that on the information board there should be no unrelated information, and people are willing to find out traffic information easily. This proves that if the view is different, intelligent traffic technology and investment are different too. Fourthly, be talked about the relation between traffic and society. Society institution and state also take effect on technical application. For example, a comprehensive vehicle administration department in China is unnecessary to use the technology of integrated information platform again. Fifthly, speaking of suitable mathematics description and model for intelligent traffic evolution, he said because of the complicated relationship between traffic and society, how to find out practical mathematics description and model has not solved yet and we should continue studying. Researcher Wang XiaoJing answered the questions put forward by representatives finally, such as ITS development trend.
