孝感市城区主要交通干道噪声污染分析研究

以孝感市城区主要交通干道城站路、北京路、交通大道和槐荫大道为研究对象,对交通噪声进行监测,同时统计车流量.分析孝感市城区整体交通噪声污染情况,以及时间和空间分布特征.研究表明,孝感市城区主要干道的总体噪声值均在75 dB左右,超过国家相应标准,其中槐荫大道噪声污染较重.交通噪声在时间上呈现周内噪声波动大,周末噪声强度大,持续时间长,与车流量有一定关系;在空间上,东西道路噪声污染较南北道路严重.

Analysis on Noise Pollution Along Main Streets of Xiaogan City

Taking the City Station, Peking Station, Jiaotong Avenue Station and Huaiyin Avenue Station along the main roads of Xiaogan City as research objective, this study monitored the main transportation noises and to calculate the traffic flow.General traffic noise pollution in urban area of Xiaogan city was analyzed, as well as the characteristics of time and space distribution.The results show that overall noise levels on the main roads in urban area of Xiaogan is about 75 dB, which is more than the corre-sponding national standard, and the noise pollution in Huaiyin Avenue Station is heavier.In terms of temporal distribution, traffic noise fluctuations is large during the week.The noise intensity during weekend noise is larger, while noise duration is longer;be-cause it has a certain relationship with the traffic flow.In special distribution, the road noise pollution of East-West Roads is more serious than South-North Roads.
