Study On Evaluation Method Of Urban Road Traffic Noise On Residential Area Environment

With the development of cities in China,the construction speed of urban infrastructure is increasing day by day,and the problem of urban road traffic noise pollution has gradually become a problem that the public cannot ignore.In the construction of urban infrastructure,strengthening the construction and protection of sound environment,maintaining people’s normal living environment and concrete measures and contents have gradually become one of the main issues of concern to the government and the public.It is also one of the main measures of urban planning and construction to improve the real living environment of residents through various effective and reasonable noise reduction measures.In the process of sound environment improvement,noise prediction is an important research content.In the traditional method of noise prediction,it is necessary to predict and analyze the noise of the predicted area first,and draw the noise map of the area through the relevant data,and then expand step by step.Noise prediction and related noise map drawing have been developed in developed countries for many years,while China is just in its infancy.This paper studies a large number of literature on traffic noise,and focuses on the analysis of traffic noise pollution in old urban areas and new residential areas in urban centers,including the measurement of field noise and the analysis of field noise.The methods of function area evaluation standard method,environmental quality evaluation index system,city noise comprehensive pollution index method and fuzzy comprehensive multi-level evaluation method are used to evaluate the traffic noise pollution of Yihe Road.Based on the research method of Yihe Road,the CADNA/A software simulation is added to the research on the noise problem of residential area near Jilin Road.By intercepting the map form of the research area,the terrain and the actual environment inside the area are modeled reasonably,and the noise map can be drawn effectively under the auxiliary function of the software.The results are compared with the actual contents and patterns,and the noise pollution situation in the case of reducing the main noise sources is predicted,and the environment of noise and the specific situation are briefly analyzed and summarized.In the course of the research,this paper,according to the actual situation in the process of social development in our country,strengthens the concrete application and analysis of urban road traffic situation and problems in real life,so as to get the corresponding results of noise prediction and actual measurement.On the basis of this research,it can realize the detailed analysis and summary of urban sound environment,and improve the basic environmental problems of cities onthe basis of urban road traffic noise,which is of great significance to the comprehensive layout of cities and the improvement of existing environment.
