上海五角场环岛地区交通组织探讨

Discussion on Transportation Organization in the Wujiaochang Circle of Shanghai

通过对上海五角场环岛地区机动车尾气排放与交通现状的调查,分析环形交叉口机动车尾气排放浓度和环形交叉口进口道延误、交通流量之间的关系,探讨改善环形交叉口环境质量的交通组织方法。

The demonstrative study shows that air quality in the vicinity of the roundabout may be improved by reasonable transportation organization, such as signal control. The work was conducted in the Wujiaochang Circle in Shanghai. Both CO and NOx concentrations are measured in the vicinity of the roundabout. Meanwhile traffic flow parameters are counted. The monitored results give a good inside understanding of relation between emission and traffic flow parameters. Both CO and NOx monitored concentrations are relevant to delay of roundabout and traffic flow. Optimizing traffic signal control can reduce the concentration for the particular case on the condition that coming flow and atmospheric parameter remain unchanged.
