The invention discloses a public traffic signal priority phase switching method, which comprises the steps of detecting the position of a bus based on a GPS, and predicting the time when the bus arrives at an intersection stop line; detecting the number of arriving vehicles of each phase through a vehicle detector arranged on each lane, and calculating the vehicle queuing length of each phase; adjusting the signal control scheme according to the arrival time of the bus and the queuing length of the bus; and selecting a corresponding phase switching method for the adjusted signal control scheme according to whether the bus phase is executed or not. According to the invention, the signal control scheme is adjusted, so that the constraint condition of the green light time is better satisfied, and the traffic efficiency is effectively improved.
本发明公开了一种公共交通信号优先的相位切换方法,包括:基于GPS检测公交车辆位置,预测公交车辆到达交叉口停车线的时间;通过设置在各个车道上的车辆检测器检测到各个相位的到达车辆数,计算出各个相位的车辆排队长度;根据公交车到达时间与车辆排队长度对信号控制方案进行调整;根据公交相位执行与否,为调整后的信号控制方案选取相应相位切换方法。本发明对信号控制方案进行了调整,使其更好地满足绿灯时间的约束条件,有效提高了通行效率。
