In the speech, two main issues are discussed. Firstly, the characteristic of the ecological city traffic is analyzed. It carries out the thought that people first, including setting up the pleasant city for inhabiting, the requisition for the structural system of the traffic and layout; ecological city demand of economizing the land and traffic resource, building taking for the ttransport services in traffic, should solve the problem of traffic energy, stopping up environmental pollution, etc. While studying the ecological city traffic transportation system of economy-oriented and ecology-oriented should be chosen. The green traffic is also introduced. It proposes using green energy and the traffic should not be harmful to urban ecology; it should be huaman-favored and safe, economical and should meet the requests of outings, should be favorable to the sustainable traffic transportation system of social development in the future. When planning the traffic of the ecological city, it should first structure the ecological city traffic and develop a comprehensive transportation demand of transporting and sets up the hydropower station near coal-mine in order to economize transportation.
The choise question of the city traffic mode has been especially analyzed while making the speech. It analyzed five kinds of city traffic modes of great international city throughout traffic development, namely : the city which the car fully develops; the mode which restricts car traffic; the mode which develops rail transportation on a large scale in order to drive the urban development; the mode which develops buses and the ones which put forward by Beijing,“Beijing traffic want with city land used for multi-way comprehensive traffic system mode.” But finally livability is emphasize and considered in the urban construction, there is no direct relationship between the economy city and the big city, and he big city is not the ecological city either.

In the speech,director Zhao is the first director of the Traffic Committee of Beijing. Since it has been established. After setting up the traffic committee, Director Zhao feels one urgent problem of Beijing’s traffic is "stop up", but actually "stop up"is the superficial sign of a contradiction brought about by modernization, urbanization and motorization. "Stop up"has many complicated reasons. These reasons causing block up are analyzed. Beijing Traffic Committee has finished the planning of Beijing new comprehensive transportation system during the recent two years, it has also finished the composition of "Traffic Development Outline of Beijing". Four problems existing in Beijing’s traffic is analyzed: 1. The construction and planning of Beijing’s traffic are out of cadence; 2. The public transport development of Beijing lags behind and the foundation is very weak; 3. The traffic capital construction in Beijing does not form a complete set, even does not link up sometimes; 4. The problem of management exists in the traffic of Beijing. The existing problem is analyzed while making the speech，finally propose how to solve the traffic problems Beijing. She puts forward two great strategies to solve the problem in Beijing’s traffic; one is to adjust the overall arrangement of urban space, generalization the urban function in Beijing, namely national capital, international city, historical city, a city suitable for inhabitation; the other is to develop public transport, into a system which taking rail transportation as its backbone, conductiong five policies and seven major actions, accelerating construction of informationization and intelligence, strengthening the traffic legislation construction.

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.
