【摘要】：本文介绍了国内外常用的交通噪声预测模式,重点介绍了公路环评的噪声预测中广泛应用的FHWA公路噪声预测模式,我国交通部推荐使用的预测模式,还有2009年环境影响评价技术导则里的噪声预测模式,通过几种模式的分析比较,并选取针对城市路段的环境特征进行三种现有交通噪音预测模型的适应性研究。并提出车型、路况、车流量等参数、环境标准与我国城市道路实际情况相符,能用于单条城市道路交通噪音预测的模型与多条城市道路交通噪音预测的模型,并进一步提出用于城市道路交通噪音预测时不同参数的选值范围。本文以长沙理工大学云塘校区周边道路为研究对象,通过2014年实地监测研究分析不同交通噪音预测模型在城市道路不同路段、车流量、距离等条件下的预测结果,并对预测结果和实际测量结果进行比较研究,通过不同路段、不同时段下多种交通噪音预测模型的预测值与实际监测的交通噪音值进行拟合计算。通过数据分析,判定用于城市道路交通噪音预测模型的适用性。此次研究的城市道路交通噪音预测模型对于不同城市路段在不同时段下交通噪音预测、环境影响评价、噪音污染分布规律具有重要的意义。但在此次研究中,各个监测点一般处于空旷、无坡度、无立交桥等复合路段,今后有待于对存在如上复合路段条件下进行进一步的研究。
[Abstract]:This paper introduces the commonly used traffic noise prediction models at home and abroad, especially the FHWA road noise prediction model, which is widely used in the noise prediction of highway environmental impact assessment, and the prediction model recommended by the Ministry of Communications of our country.The noise prediction model in the technical guideline of environmental impact assessment in 2009, through the analysis and comparison of several models, is selected to study the adaptability of three existing traffic noise prediction models according to the environmental characteristics of urban road sections.The model, road condition, traffic flow and environmental standard are in accordance with the actual situation of urban roads in China. It can be used to predict the traffic noise of single urban roads and multiple urban roads.Furthermore, the selection range of different parameters for urban road traffic noise prediction is proposed.This paper takes the surrounding roads of Yuntang Campus of Changsha University of Technology as the research object, and analyzes the prediction results of different traffic noise prediction models under different road sections, traffic flow, distance and other conditions through the field monitoring study in 2014.The prediction results are compared with the actual measurement results. The prediction values of various traffic noise prediction models and the actual traffic noise values monitored in different sections and different periods of time are fitted and calculated.Based on the data analysis, the applicability of the noise prediction model for urban road traffic is determined.The prediction model of urban road traffic noise is of great significance for traffic noise prediction, environmental impact assessment and noise pollution distribution of different urban sections in different periods of time.However, in this study, the monitoring points are generally in the open, no slope, no overpass and other composite road sections, and need to be further studied in the future.
