几种常用道路交通噪声预测模式在较高等级城市道路中的应用——以深圳市城市道路为例

Noise analysis and discussion on control technique of Gas-Steam Combined-cycle Power Plant

本文以深圳市城市高速路、城市快速路和城市主干路等三类较高等级的多条典型城市道路交通干道为研究对象,通过实际监测与模式预测对比研究,分析和验证FHWA模式、规范模式、导则模式和RSL90模式等四种常用道路交通噪声预测模式在较高等级城市道路交通噪声预测中的准确性。研究结果表明,各模式预测的准确性高低依次为:导则模式、规范模式、RLS90模式、FHWA模式。

This paper select several higher levels typical road including the High - speed road, Expressway and Main road of Shenzhen city as the object of study, through the comparison of the actual monitoring and prediction model, analyse and test the noise prediction accu- racy of the FHWA model, Norm model, guideline model and RSL90 model in higher level city road. Research resuhs show that the accuracy of the model prediction, height is in turn ： the guide model, Norm model,, RLS90 mode, FHWA model.
