摘要
对干线上相邻交叉口进行协调控制可以有效地减少干线上车辆延误和排队次数;但是通过对以往干线协调控制的研究发现,主要是以直行车辆延误最小为目标,忽略了干线上的左转车辆。在分析以往协调控制优化的基础上,通过VISSIM交通仿真系统,分别对传统方法、Matlab优化后方法以及禁左后进行协调控制的方法分别进行三次仿真;通过对比发现禁左后干线的延误和排队次数以及干线的西门子交通服务水平评价指标PI值均有显著降低。禁左对于改善目前城市交通拥堵的现状以及提高干线道路的服务能力具有非常积极的意义。
Coordination control of trunk adjacent intersection can effectively reduced trunk vehicle delays and queuing times,but the found on the previous study on arterial coordination control.Previous studies mainly used the straight line vehicle delay minimum as the goal,and ignored the trunk of left turning vehicles.Based on the analysis of the former coordination control optimization,the VISSIM traffic simulation was used to simulate the traditional method,MATLAB optimization method and coordination control of prohibit left method respectively.By compara-tive analysis,the delay can be found and queuing times of prohibit left trunk and the trunk Siemens transportation service level evaluation index PI values were significantly reduced.Prohibit left has a very positive significance to improve the current situation of urban traffic congestion and improve the service ability of trunk roads.
