快速公交信号控制优化策略

Bus Rapid Transit Signal Control Optimization Strategy

快速公交信号控制优化是保证车辆运行的稳定性和提高快速公交系统服务水平的有力手段。通过分析交叉口有限的时空资源,明确影响快速公交信号控制优化的因素。结合广州市快速公交运营情况的调查分析,确定快速公交信号优化控制启动的阈值。以均匀车头时距、减少下游乘客的候车时间并兼顾其他社会车辆的延误为控制目标,不仅针对晚到的BRT车辆采取优先的信号控制策略,还针对早到的BRT车辆提出了抑制的信号控制策略,并设计了快速公交信号优化控制的流程,从而为快速公交信号优化控制策略和方案的制定提供依据。

Bus rapid transit signal control optimization strategy is the powerful means to ensure the running stability and improve the service quality of bus rapid transit.By analyzing limited space-time resources at intersection,the factors affecting bus rapid transit signal control optimization were indentified.The threshold values of the above factors arousing bus rapid transit signal control optimization were determined based on the survey and analysis of bus rapid transit operation in Guangzhou.Not only the later bus rapid transit was taken the prior signal control strategy,but also the earlier bus rapid transit was taken the prohibitive signal control strategy to uniform the headway,reduce the waiting time of downstream passengers and simultaneously considerate the delay of the other general vehicles.The technological process of bus rapid transit signal optimization control was designed to provide accordance of developing the strategy and scheme of bus rapid transit signal optimization control.
