【正文】 rocessing, the data warehouse technology, data developed in recent years excavate technology etc. and show the good application prospect. Meanwhile, DSS which supports administrative decision of the different levels is a respect that the researcher pays close attention to too, its subject matter needing to study is how to utilize a large amount of information that the information work offers, excavate out the content cared about by oneself from it。s knowledge and experience, give play to the whole advantage of the integrated system to solve the practical problem. This theory method has offered the foundation for the fact that we determine the nature in traffic planning the ration bines together, contribute to improving the method of decision theory facing plicated huge system. According to planning research contents, develop urban public transport, promote the settingup of the rational traffic mode, cause people39。 The citizen39。s plan etc. and have important function, several parts of gathered by information, information processing, information issue make up. The environmental protection system of the traffic is prevented and cured and monitored two basic parts to make up by waste gas, noise, vibration, its hardware including sound insulation wall, decorating low in noisely, the bridge shock attenuation device, specialpurpose monitoring device of traffic pollution,etc.. The purpose of the scientific and technical subsystem is to promote the technological progress of the trade through technology popularization and technical training, it forms and includes service system of the scientific information, new technology popularization system, academic discuss system,etc., the hardware has to go to the support that key laboratory, department open laboratory, the fictitious laboratory of work, information information Web serve the node, observe the experimental system etc.. Among them the fictitious laboratory of work carries on domain engineering research of relevant road traffic and scientific research, carry on the important base where the high project of the road traffic field educates, popularizes the new concept of the new technology。s managerial staff member as the target of using, rely on the work system of the puter, support the manmachine system of government39。 Environmental protection function, improved the utilization efficiency of the unit land, the ones that reduced to nature were asked for and discharging。 Study and implement development of the public traffic system and technological progress conscientiously。 Improve traffic administration。 Support function, offer the basic support frame of the regional space。 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 tim
