公交优先信号控制交叉口延误分析与控制方法改进

公交优先策略是减少公交车延误的一种有效、可行的方式。通过模拟分析发现，交叉口人均延误减少量与公交车流率及优先时间的长度有关。为降低交叉口人均延误，对公交优先信号控制方法进行改进并使用软件进行仿真验证，结果表明，改进后的公交优先信号控制方法能够明显降低交叉口入均延误。

Delay Analysis and Signal Control Amelioration of Intersection Using Bus Priority Signal-planning Strategy

Bus signal priority at signalized intersections is an efficient and feasible approach to reduce bus delays.Through the simulation analysis,it is found that the average passenger delay is relevant with the bus arrival rate and the priority time.In order to reduce the average passenger delay,the signal-planning is improved and the simulation results demonstrate that improved signal-planning method can reduce average passenger delay significantly.
