快速公交BRT交叉口信号配时优化研究

摘要

For intersection traffic characteristics of BRT through the analysis of the traditional design of phase signal timing,the optimal design based on bus priority signal control was summarized.The typical BRT intersection was used as a case study,respectively using the traditional phase design and bus priority optimization method to designed four different timing plans.Using VISSIM software,the simulation analysis was conducted on different signal timing plans of BRT intersection,to verify the effectiveness of bus priority signal timing optimization method.The signal timing optimization method based on the bus priority was obtained,which can effectively reduce delays per capita at the intersection.%针对快速公交BRT交叉口交通特性,通过分析传统的相位设计与信号配时,总结了基于公交优先的信号控制方案优化设计.选取乌鲁木齐市典型的BRT交叉口进行实例分析,分别采用传统的信号配时方法与公交优先的配时优化方法设计了4种不同配时方案.利用VISSIM软件对BRT信号交叉口的不同信号配时方案进行仿真分析,对公交优先的信号配时优化方法的有效性进行对比验证,得出基于公交优先的信号配时方法能有效减少交叉口人均延误,实现公交优先.
