【正文】 s traffic, the government39。 The system offers the services of the distance learning experiment and project experiment mainly. The public serves and participates in the subsystem to occupy the irreplaceable status in the integrated system of the road traffic, the traffic needs the public to participate in closely, to public service including information service, rescuing the service, management service,etc., for example is the public to serve the concept system that the system for traffic guiding, parking area guide the system, public transport services information system etc. in the intellectual traffic system。s. Recall predicament city traffic fall into, Bangkok of Thailand, a lot of serious waste gas that city traffic lead to the fact pollute, public transport dangerous shrinking and is inclined to etc., can see clearly how greatly the responsibility that the government bears is in the city traffic of our country. Compared with this kind of responsibility, the technical support won during the process of making traffic development strategy, policy, planning and management of government organs of our country seems insufficient to some extent, not so sound information system, management system, not so unblocked to order important problem overe further to need with municative channel of expert,etc. that cut apart. The government planning to build to this situation manages the subsystem, regard government39。 Adopt the policy means to impel the technology innovation of the traffic trade, have priority to popularize and economize the resource and energy, improve technology of the operational efficiency of the traffic system,etc.. Question of the third level ( Technology layer) : Strengthen the application of the information technology in the traffic engineering, such as the system for traffic guiding, integrated information system of the traffic,etc.。 Improve inhabitting working environment and life quality of residents. This goal needs and could be realized effectively through the efforts of the multiple channel, it produces the function in many aspects on this goal to build as the traffic of the important ponent of the infrastructure: Guide function, the guide to that the area social economic space shape developed。 Combine the standard level of service level of the traffic。 In conformity with demand for sustainable development, support and utilize traffic planning DSS and information that plan to bine together to gather the administrative system with the land, give full play to system for traffic guiding of the facility ability of the traffic,etc. and bee important members in the facility system of traffic further. Behind the ones that formed the content and changed in this kind of hardware facility, designing the renewal of the idea, change of the infrastructure construction object of the traffic,etc. are playing an important role. Developed country intelligent traffic system plan for example with America,Europe and Japan,etc., surface think this change and change of technology, traffic system of structure, have increased the system for traffic guiding, information system of the traffic,etc. in the traditional traffic system, and has adopted technology of the puter, control technology, munication technology,etc. to carry on technological transformation. In fact it is this understanding that plays a supporting role in the backstage: Under the circumstances that the limited land resource and environmental resources are restricted, the traditional traffic system is unable to meet the traffic demand for increasing constantly, must transform through adopting the modern new and high technology, improve the utilization efficiency of resources. Has formed a series of new systematic concepts on this basis, for example: The information system of the prehensive traffic offers such information as traffic blocking, traffic accident, running time of the road on ,etc., offer the information of the public transport, help people to choose suitable traffic way, appropriate going out time, rational traffic route, impel the traffic to go out and is distributed and distributed rationally in the prehensive traffic work, in order to lighten the burden of the whole traffic work. The system for traffic guiding offers information service to the vehicle driver, help them to find out about the traffic jam state of the work of the whole road, lead them to avoid the crowded highway section or the crossing, impel the whole road work load to melt evenly, achieve the goal of improving utilization efficiency. Freight transportation administrative system supported by traffic information, make plan, dispatcher of vehicle, rationally, offer the goods to collect and mix service,etc., it was highefficient that its goal promoted freight transportation. Passenger traffic supported by traffic information administrative system, manage the operation vehicle rationally, offer public transport services information, in order to improve the service level with systematic passenger traffic, attract more flow of passengers, lighten the burden of the whole urban traffic system. The control system of automatic steering is supported by automatic control technology, improve the vehicle traffic capacity of the area of the road to the unit, and strengthen the traffic security. Therefore, in the proposition course of the new traffic system concept, need newer conduct of the idea and goal to lead the way. Our times, sustainable development has already bee the strategic objectives of a lot of countries, our country also regards it as great strategy to implement. Premier Li Peng led the group to attend the meeting of environment and development of the United Nations in 1992 ( UNCED) ,Promise solemnly China will fulfil the file that the meeting passes, the General S
