本文提出等效车流量的概念，把一般情况下预测交通噪声时必需用到的车流率、车辆分布、车速、车辆六功率等因素，都通过等效车流量的概念表示出来，从而使预测模型相当简洁。用此方法对杭州市典型道路进行预测分析，效果良好。
In this paper, the concept of equivalent traffic flow is proposed. The traffic flow rate, vehicle distribution, vehicle speed and six-vehicle power are all used to predict traffic noise in the general case. The concept of equivalent traffic flow is used to make the prediction model Very simple. Using this method to forecast the typical road in Hangzhou, the result is good.
