The invention discloses an intersection-crossing bus priority demand time window calibration method, which comprises the following steps of virtualizing a bus station and a signalized intersection into computing nodes; according to bus travel time between adjacent nodes, signal timing delay in signalized intersection nodes and stop time characteristics in bus stop nodes, probability distribution calculation models of buses arriving at and leaving the nodes are constructed respectively; through a retrieval table of a signalized intersection bus route entrance direction, crossing-intersection transmission of upstream bus information is effectively realized, and arrival probability distribution and a maximum distribution segment of the buses at the signalized intersection are obtained; an active vehicle request table of a bus request phase is dynamically updated, and a demand time window of the bus request phase is timely adjusted on the basis of the earliest maximum arrival probability distribution segmentation in the table, so that powerful data support is provided for a bus signal priority control strategy.

    本发明公开了一种跨路口的公交优先需求时间窗的标定方法,其包括以下步骤:将公交站台与信号交叉口虚拟化为计算节点,依托相邻节点间的公交车辆行程时间、信号交叉口节点内部的信号配时延误及公交站台节点内部的驻站时间特性,分别构建公交车辆到达与离开节点的概率分布计算模型;通过信号交叉口公交线路进口方向的检索表,有效实现上游公交车辆信息跨路口传递,获取信号交叉口公交车辆的到达概率分布及其最大分布分段;动态更新公交请求相位的活跃车辆请求表,并以表中最早的最大到达概率分布分段为依据,及时调整公交请求相位的需求时间窗,为公交信号优先控制策略提供有力数据支撑。
