| 摘 要： | 交通供需矛盾的激化突出表现在城市路网的节点（交叉口）上,对于大城市的干道来说饱和交叉口成为制约信号协调效果的瓶颈。从分析饱和车流的特性入手,基于排队长度消散或有侧重均衡交通压力的思想提出了在传统信号配时失效的情况下一种利用VISSIM反馈评价参数调整绿信比优化的方法,并针对这种方法进行信号协调控制的应用研究。

| Abstract: | The contradiction of demand-supply markedly are manifested at the intersections in urban,the over-saturation intersections as traffic bottlenecks influence the smooth coordination of traffic signals for the arteries in big cities.This paper analyzes the characteristic of saturation vehicle flow,and gives a method of green ratio optimization which parameters adjusted by VISSIM while the Webster lapses based on queue clearance or proportion pressure,then have a green wave signals design under the traffic condition. |

| Keywords: | green ratio optimization queue clearance traffic signals coordination oversaturated traffic |
