摘　　要：引进等效流量与等效车速的概念,对美国FHWA道路交通噪声模型进行修正,建立适合我国的交通流影响因子与道路交通噪声的线性对数关系模型。再选取哈尔滨市18条道路的42个监测点采样数据,运用软件SPSS13.0,通过回归分析的方法确定模型的参数,并对建立的模型进行F检验及拟合度分析。模型通过F检验,且拟合度较高。最后对哈尔滨市8个监测点噪声的预测值与实测值做对比分析,预测值与实测值差值较小,此建立的模型可应用在哈尔滨市道路交通噪声的预测。By introducing the concept of equivalent flow and equivalent speed,and correcting the traffic noise prediction model of U. S. FHWA,a linear logarithmic model of relationship between traffic flow impact factors and road traffic noise was established, which is suitable for our country. Then,the data collected from 42 monitoring points of 18 roads in Harbin were selected to determine the parameters of the model. Parameters were determined by regression analysis method by using SPSS13. 0 software,and F-test and degree of fitting analysis were applied to the model. The result of F-test was good and degree of fitting was higher. Finally,noise predicted values were compared with actual values from eight monitoring points in Harbin. The differences between them were low,which indicated that the model can be applied to predict road traffic noise in Harbin.
