学府大道双向干道绿波控制研究

Study on the Traffic Signal Green Wave Control Design of Urban Rode

基于对学府大道上六个交叉口交通状况的大量调研,提出该路段各交叉口信号控制现状的不合理。首先利用韦伯斯特配时模型优化各交叉口单点控制,然后引用数解法,针对学府大道上的研究交叉口群进行信号协调线控设计。最后,利用VISSIM交通模拟软件对线控配时方案进行仿真验证,通过比较道路通行能力和延误时间的变化,证明通过该双向绿波控制可有效地改善干道交通运行状况。

Urban traffic congestion is a serious and gradually increasing problem ,followed by a deterioration of road network capacity .Appropriate traffic signal control strategy can play a role in ease urban traffic congestion ,so the research is of great significance .Academy Boulevard through the intersection w hen the traffic light long distance between the intersection group and of the signal wire .Finally ,traffic simulation software VISSIM wire timing simulation program by comparing before and after design changes in road capacity and delays the combined effect of the changes and improvements in transportation ,proof unidirectional green wave coordinated ough the intersection ,thereby improving the main direction of traffic operating conditions .
