基于运行速度的公路交通噪声研究

Study of Highway Traffic Noise Based on Operating Speed

道路交通噪声对环境的污染已成为一大公害,为了提高道路交通运输的舒适性,通过某旅游区公路实地数据采集,采用对比分析法,分析不同车型,不同车道位置,满载和空载车辆在不同运行速度的情况下的噪声规律,得出道路交通噪声与机动车运行速度之间关系,最终为人类治理和控制交通噪声提出了理论依据。

Traffic noise has become one of urban environment nuisances. In order to improve road traffic comfort, we acquire fireld data through a tourist area highway and use the contrast analysis to analyze different models, different lane position, full load and light vehicles in different running speed under the condition of the law of the noise. Work out the relationship between that road traffic： noise and the speed of motor vehicle running, for the human management and control traffic noise proposed the theoretical basis finally.
