广东省道路交通噪声预测统计模型

A statistical prediction model for roads traffic noise in Guangdong,China

为了建立符合广东省的道路交通噪声预测模型,在国内学者相关研究成果的基础上,对FHWA模型进行了深入分析,并根据道路交通噪声预测模型原理,引入等效车流量等概念建立了理论噪声预测统计模型。在此基础上,对广东省市政路和高速路的交通噪声实测数据进行多元线性回归分析,确定广东省交通噪声预测统计模型。经验证,在广东省交通噪声预测评价中该模型预测精度非常高。该研究思路与方法值得在全国各地区处理交通噪声环境问题的工作中加以推广与应用。

In order to establish the road traffic noise prediction model in Guangdong,we made a in-depth analysis of FHWA model based on the related studying achievement by domestic scholars,and introduced the concept of equivalent traffic flow to simplify model according to the principles of the traffic noise prediction,then made the multiple linear regression analysis of the measured sample data from the chosen urban roads and highways in Guangdong. It is validated that the model can be used in the appraisals for noise pollution forecasting accurately. This method is worth recommending and applying in processing of traffic noise problems all over China.
