| 摘 要： | 基于速度-密度关系模型,由浮动车速推算出广州市路网的交通流量,并从地理信息系统(GIS)加载道路及建筑物的属性信息作为噪声计算的输入参数;然后结合单车辆噪声排放模型及噪声传播扩散的基本原理,考虑城市建筑物群对交通噪声的遮挡衰减,建立了城市尺度的交通噪声计算模型,计算出了广州市的交通噪声值,并绘制出了广州市的交通噪声地图,结果可为广州市交通噪声污染的控制提供科学参考依据。

| Abstract: | Based on the speed-density model,road traffic volume of Guangzhou was calculated according to the floating car data,and the information of roads and buildings was obtained from the geographical information system(GIS).Then combining the noise emission and propagation model,and considering the attenuation of buildings,city traffic noise calculation model was developed.At last,road traffic noise of Guangzhou was calculated and traffic noise map was made,results can be used for traffic noise pollution control in Guangzhou. |
