高速公路互通立交交通噪声预测研究——以昆明绕城高速公路为例

Research on Traffic Noise Forecast of Interchange Expressway by Taking Circling Around Expressway of Kunming as an Example

道路交通噪声污染在我国城市地区已很严重。高速公路互通立交运营期的交通噪声比较突出。对几个交通噪声的预测模型进行比较和选择,并以昆明绕城高速公路为例,预测和分析了其互通立交的交通噪声,为噪声污染防治提供了依据。

Road traffic noise pollution has been serious in recent years in China. expressway is prominent. Several traffic noise forecast models are compared and The traffic noise from interchange selected by taking circling around expressway of Kunming as an example. The traffic noise forecast of interchange expressway is predicted and analyzed. It provides references for noise treatment.
