摘要：结合美国道路交通噪声污染预测模型(FHWA)和国内学者在该方面的大量研究成果,选择兰州市主、次干道共计52条、142个监测点的建模采样数据,并应用统计学原理分析了影响道路交通噪声的各个因子与道路交通噪声的相关性,最终得出了符合兰州市道路交通特征的噪声污染统计预测模型.随后通过兰州市15个监测点的预测与实测对比验证后发现二者具有较高的一致性,此模型可应用在兰州市道路交通噪声污染的预测评价中.

Abstract：This paper combined the forecast model of the noise pollution in the road traffic by USA (FHWA)and the massive research achievement by domestic scholar's in this filed, totally chosen sample date on the established model from the 52 roads and lanes, 142 inspecting sites in Lanzhou city, and analyzed the relevance between the factors influencing the noise in the road traffic and the noise in the road traffic itself based on the principal of statistics, and finally set up the statistical forecasting model of noise pollution in conformity to the road characteristics of Lanzhou city. Then, the forecasting by 15 inspecting sites and the real test are found consistent with each other to a high degree, and this model can be used in the appraisals for noise pollution forecasting in road traffic of Lanzhou city.

Key words：the equivalent noise grade in succession (Leq) FHWA road traffic statistical model influence factor Lanzhou
