【正文】 the mode of encouraging reducing the traffic and going out and less resources consume. The information technology is entering the traffic engineering field rapidly, the intellectual traffic system is set up on the basis of information technology, its core is an information system of traffic. The traffic information system of our country is still very backward, gather the system, information very not so abundant to process and utilize in information of traffic not so perfect, it is all problems needing to solve especially to await improved information issue means,etc.. The integrated system of the road traffic is one multidimensional world, information is playing an important role among them. Choose the behavior to finish supported by information in people39。s traffic, the government39。s traffic is strategic, traffic planning, traffic policy are made supported by information, the daily administrative decision of the management organization of the traffic is due to a information foundation even more. It is the bination of puter and munication technology that need to pay attention to at present, especially information dissemination and information on the puter work foundation of wide area are gathered. As the information technology carrier, the system for traffic guiding, information system of the traffic, traffic control system are playing a very important role in the modern road traffic system, traffic subject they It is the organic whole that people or the thing, means of transportation, traffic infrastructure, vehicle supervision department get in touch, the efficiency that causes not in tune drops after reducing because within the system. The research work of the system for traffic guiding has already been launched in our country, the present focal point of work one is that an overall frame of the system is studied and makes a concrete analysis of the model to study, worth paying the essential attention as the traffic behavior of basic theory. The present research of information system of the traffic is mainly to attempt to synthesize the information of various fields, offer and meet the need of different tasks with information picture of the level after processing, 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。 How decisionmaking process that the ration bines together to determining the nature offers effective support。 How to meet the decision characteristics of the different levels,etc.. In the course of technical application of information, what merits attention is that the trends of the overall arrangement, overall coordination are dispersed, what master plan is emphasized is the standard of an agreement, but not adhere rigidly to the technological detail, this can make huge information system sporadic development step by step, put in place progressively, degree of difficulty developed with the reduction system. The environmental protection technology of the road traffic remains the focus that will pay close attention to in the future. The prevention and cure means of the automobile waste gas is mainly to adopt clean energy, tail gas purification, and adjust and control and reduce the automobile to use through the policy. In addition it is the research of strengthening engineering that need to pay attention to, analyse the diffusion law of the waste gas under the specific environment, pollute for the waste gas which lightens some position. The settingup of the specialpurpose monitoring system of waste gas pollution of road traffic is a very important task too, the data that this kind of specialpurpose system set up abroad accumulated throughout the year have created very good terms in order that its environmental countermeasure is made. Noise prevent and cure in the field of traditional research facing a lot of subjecting still, can use engineering evaluation and noise of engineering design for propagate basic law is it remain and deepen even to study, the design of the sound insulation wall remains to improve, low in noise road surface technology remains to carry on the project experiment and popularize further. In addition, consider in traffic planning the environmental protection factor is forming the focus, especially the land is utilized, urban system structure and traffic skeleton cooperate each other, it is a research focal point in the planning to form ecology urban system structure. In the course of formulation of the concrete programme, the capacity of traffic environment is analysed technology has better practical prospects. Asking for in order to reduce to nature, adopt the old and useless material to build road and is still worth paying great attention, fly ash, abolishing slags,etc. are used in the road bed and build and make very good result, still need to study the material as building the road of industrial waste material further, and the old way of road transforms the old and useless regeneration that dripped in the course. It is a field that is worth launching that the dependability of the traffic work is studied, especially should pay enough attention even more in the work planning of urban road. Our country is going through a new urbanization course at present, need to consider conscientiously that prevent and rescue the question to such great natural calamity as the earthquake,etc. in the course of planning of city layout, lay a good foundation for the further development of the city. After the great e
