城市交通排放污染实验及关键影响因素

Experiment on traffic exhaust pollution near urban road and its critical influence factors

为研究影响城市交通污染的关键因素,通过交通污染的特征分析其影响因素,选取上海市杨浦区的路段进行污染物浓度、交通流性态和气象条件的观测,并运用软件对采样数据进行主成分回归,结果表明交通流量和交通流运行状态是影响城市交通排放污染的两个关键因素,并提出减少交通污染的控制措施。

The relative factors are analyzed in order to find the critical influence factors of the traffic exhaust pollution. A roadside ambient HC, NOx and CO sampling is measured in Yangpu District of Shanghai, and traffic characteristics and meteorological condition are recorded as well. The regression on principal components is adopted to analyze the data. The result indicates that traffic volume and running condition are the critical influence factors of urban air pollution, and the methods to reduce the traffic exhaust pollution are put forward.
