FHWA公路交通噪声预测模型在广清高速公路花都段的应用研究

The Study on Application of FHWA Highway Traffic Noise Prediction Model in Huadu Section of Guangzhou to Qingyuan Expressway

通过运用FHWA公路交通噪声预测模型对广东某高速公路交通噪声进行预测。根据车流量实测数据以及设计速度,通过模型对敏感点噪声结果进行计算,并根据计算结果,反向计算满足声环境功能区划的最大行车速度,并对不同车型,不同设计速度的降噪效果进行了分析。结果有望对同类高速公路噪声预测提供指导和依据。

This paper adopted FHWA highway traffic noise prediction model to predict the traffic noise of an expressway in Guangdong. According to the testing data of traffic flow and design speed, the noise in sensitive points was calculated by the model. Backward calculation was done on the maximum driving speed that satisfies acoustic environmental function zoning based on the calculation results. It also analyzed the noise reduction effects for different vehicle models and design speeds. The results were expected to provide guidance and basis for the noise prediction of similar expressways.
