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.

Key words: intelligent Traffic, informationization, the freeway charge system, information board of the traffic, mathematics description and model

摘要： 首先分析了智能交通应产生的效益，并以ITS收费系统为例分析了日本实施自动收费后，所产生的效益以及日本在发展VICS系统所取得的效果。而在欧洲、美国ITS效果就不怎么成功，这是与他们运作方式和社会习惯有关。其次，谈到信息化引起交通管理的变化，运输工具的信息都是单向作用的，作为运营商，按照线网和能力要求考虑问题，制定了运行时间表，乘客和货主就得按网上安排它们的出行和运送。我们已进入ITS发展时代，就要根据用户需求安排网络，以及对整个管理的影响，这说明现代技术带来的变化。第三，谈到建设智能交通如何节省投资问题，举出了北京二环路和三环路可变交通信息板使全屏显示，投资较大，而上海有一个节省投资的理念，在信息板上，不应该有与交通无关的信息，而且要让人一眼就能把交通信息看出来，这说明观念不一样，就确定了智能交通技术运用的不同、投资也不同。第四，谈到交通与社会的关系、制度和社会形态对技术应用也有影响，如中国一个综合交通管理部门，我们就没有必要再使用综合信息平台这项技术了。最后，谈到对智能交通发展过程能否可用数学描述和模型现在尚未解决，请大家继续研究。
