上海市高架道路车辆密度与污染物浓度的实测研究

Experimental study on vehicle density and pollutant concentration on Shanghai elevated road

通过对上海市高架道路上车辆的车速、流量进行实测统计,计算出最大的车流量和最佳车速.并对高架道路上的空气污染物进行分析,研究了车辆密度与流量、车速和污染物之间的关系.结果表明,通过降低车密度,不但提高了通行效率,缓解了交通堵塞,而且还减少了高架道路上的空气污染.

A statistic survey of vehicle velocity and vehicle flux on Shanghai urban elevated road was done. The maximum flow of vehicle and the optimal speed was calculated. The pollutant in the air on elevated road was analyzed. The relation between vehicle density and pollutant concentration in the air was studied. It indicates that when the vehicle density is decreased, the traffic efficiency will be heightened and the air pollution concentration on the elevated road will be decreased.
