对公路项目环境影响评价中常用的交通噪声预测计算模式(FHWA模式和规范模式)进行分析,并针对其存在适用范围较窄、个别参数确定困难等缺陷,介绍一种新的噪声预测模式—统计模型。该模型具有适用范围广、计算简单、准确性高等优点,可为交通噪声污染防治提供可靠的技术依据。 This paper analyzes the traffic noise prediction calculation model (FHWA model and normative model) commonly used in the environmental impact assessment of highway projects. Aiming at the defects of narrow applicable range and difficult to determine the individual parameters, a new noise prediction model is introduced model. The model has the advantages of wide range of application, simple calculation and high accuracy, which can provide a reliable technical basis for the prevention and control of traffic noise pollution.
