The invention relates to an emergency vehicle grading priority signal control method and device, electronic equipment and a medium, and the method comprises the steps: determining the priority of an emergency vehicle based on the type of the emergency vehicle and the emergency index of an emergency, and determining the phase demand degree of the emergency vehicle based on the priority of the emergency vehicle and the current road traffic flow state; acquiring a signal lamp state when the emergency vehicle arrives at the downstream intersection of the initial position; and making a control strategy based on the phase demand degree of the emergency vehicle and the signal lamp state when the emergency vehicle reaches the downstream intersection of the initial position. According to the invention, the emergency vehicles are subjected to grading research, different priority passing rights are given at the intersection according to the priorities of different types of emergency vehicles, and the passing efficiency of the emergency vehicles is improved.

    本发明涉及一种应急车辆分级优先信号控制方法、装置、电子设备及介质,其方法包括:基于应急车辆类型和突发事件的紧急指数确定应急车辆的优先级,并基于应急车辆的优先级和当前道路交通流状态确定应急车辆的相位需求度;获取应急车辆到达初始位置下游交叉口时的信号灯状态;基于应急车辆的相位需求度和应急车辆到达初始位置下游交叉口时的信号灯状态制定控制策略。本发明通过对应急车辆进行分级研究,根据不同类型的应急车辆的优先级在路口给予不同的优先通行权,提高应急车辆的通行效率。
