Based on the FHWA for the establishment of road traffic noise prediction model in Lanzhou city
基于FHWA的兰州市道路交通噪声预测模型的建立

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.
