为了解快速路交通噪声的分布特征及污染现状，对城市快速路的交通噪声进行监测，结果表明，噪声随车流量的增大而升高，同时受车辆类型等其他因素的影响；随着与快速路水平距离的增大，交通噪声值呈下降趋势，特别是在距离快速路路沿前40 m内噪声衰减尤为明显；距高架道路不同水平距离处的噪声声场垂直分布规律基本一致，但距离高架道路较远处的敏感建筑物噪声值最高点楼层有所上移；快速路旁噪声敏感点交通噪声超标情况严重。

Through the traffic noise monitoring of urban freeway, the noise distribution characteristics and pollution status were stud-ied.The results showed that the traffic noise increased with the increase of traffic flow, and at the same time it was affected by other factors such as the types of vehicles.Traffic noise decreased with increasing horizontal distance from freeway, especially within the distance of the first 40 meters from the freeway edge.The vertical distribution rule of the traffic noise was basically similar at differ-ent horizontal distances from freeway, but the floor having the maximum noise value was higher in the more distant building.The noise of the sensitive points along freeway exceeded the environmental quality standard for noise severely.
