The invention provides a method for realizing the cooperative priority of multiple buses, and the method can give consideration to the passing demands of buses with low priorities while serving the passing intersection of buses with high priorities. Firstly, a priority control phase queue is constructed based on phase minimum green; then, calculating a green light backward shift interval of each phase of the priority control phase queue based on the phase maximum green; then, aiming at buses requesting priority, a phase green light backward movement interval optimization model is established, and the model optimizes the green light backward movement interval of each release phase of the priority control phase queue in real time on the premise of ensuring the priority of high-grade buses and taking the priority of low-grade buses as a control target; and finally, selecting a reasonable value from the phase green light backward shift interval, and calculating and outputting the green light release duration. The output value is the phase green light constraint interval and can be converted into the phase green light release duration interval, so that the phase green light can be dynamically adjusted according to the actual traffic demand, and the method has great flexibility.
本发明提供了一种多路公交协同优先的实现方法,该方法能够在服务高优先等级的公交车辆通行路口的同时,兼顾低优先等级的公交车辆的通行需求。首先基于相位最小绿构建优先控制相位队列;然后,基于相位最大绿计算优先控制相位队列各相位的绿灯后移区间;接着,针对请求优先的公交车辆,建立相位绿灯后移区间优化模型,该模型以保证高等级公交优先为前提,兼顾低等级公交车辆优先为控制目标,实时优化优先控制相位队列各放行相位的绿灯后移区间;最后,从相位绿灯后移区间中选择合理的值计算并输出其绿灯放行时长。本发明的输出值为相位绿灯约束区间,可转化为相位绿灯放行时长区间,使得相位绿灯可根据实际的交通需求动态调整,具有很大的灵活性。
