The invention discloses a method for realizing priority of multiple buses under coordination control. The method comprises the following steps of: firstly, establishing a bus priority request chain table by taking a detection moment when the buses approach an intersection as a starting point and a moment when the buses leave a stop line as an ending point; calculating expected adjustment values and adjustment stage numbers of all requested buses; on the premise that coordination is not damaged, the adjustable range of each bus before arriving at the stop line is calculated; and finally, by taking the minimum waiting time of all buses at the intersection as a control target, adjusting the time output of the current stage based on the principle of first arrival and first service, and reducing the waiting time of the buses. According to the method, the starting time and the release duration of the coordination stage can be considered while the operation efficiency of the public transport vehicle is improved.
本发明公开了一种协调控制下的多路公交优先实现方法,该方法首先以公交驶近交叉口检测时刻为起始点,公交离开停车线时刻为结束点建立公交优先请求链表;然后计算所有请求公交的期望调整值和调整阶段数;接着以不破坏协调为前提,计算各公交到达停车线之前的可调整范围;最后,以交叉口所有公交车辆等待时长最少为控制目标,基于先到先服务的原则,调整当前阶段的时长输出,减小公交车辆的等待时间。本发明的方法能够在提高公交车辆运行效率的同时,兼顾协调阶段的起始时刻和放行时长。
