The invention belongs to the technical field of intelligent traffic control, and particularly relates to a bus signal priority control method, platform and system. The method comprises the following steps that the speed and position information of a bus is obtained, and if the distance between the bus and a stop line of a current intersection is smaller than a set threshold value and larger than a first distance and the speed is not zero, whether priority control is carried out or not is judged according to the speed and the distance of the bus; if the distance between the bus and the stop line of the current intersection is smaller than or equal to a first distance and the speed is 0, whether signal priority control needs to be carried out or not is judged according to the speed and the acceleration when the bus is started, and the priority control strategy comprises the steps that if the bus cannot pass through the current intersection within the remaining time of the green light, a green light time prolonging instruction is issued; if the bus can arrive at the stop line of the current intersection within the remaining time of the red light, issuing an instruction for shortening the red light time; the control process is simple, and is suitable for the automatic driving vehicle, so that the signal priority control time is more accurate.
本发明属于智能交通控制技术领域,具体涉及一种公交信号优先控制方法、平台及系统。其中,该方法包括以下步骤:获取公交车的速度和位置信息,若公交车与当前路口停止线的距离小于设定阈值且大于第一距离,速度不为0时,根据公交车速度和距离判断是否进行优先控制,若公交车与当前路口停止线的距离小于等于第一距离且速度为0时,根据公交车启动时的速度和加速度判断是否需要进行信号优先控制,优先控制策略包括:若公交车在绿灯剩余时间内无法通过当前路口,则下发延长绿灯时间指令,若公交车在红灯剩余时间内能够到达当前路口停止线,则下发缩短红灯时间指令;该控制过程简单,并且适用于自动驾驶车辆,使得信号优先的控制时间更加精确。
