The invention relates to an emergency vehicle control method based on an intersection dynamic lane in an intelligent network connection environment, and belongs to the field of emergency traffic control. The method comprises two parts of macroscopic planning and microcosmic control. According to the macroscopic planning part, an optimal path from an emergency vehicle to an accident point is planned through an A * algorithm, and a traffic organization method of each intersection is determined. According to the micro control part, an intersection is divided into a normal driving area, a buffer area and a conflict area through the vehicle-road cooperation technology, a road side control unit is used for planning a special lane for emergency vehicles, then other vehicles in the special lane are regulated and controlled to change lanes and enter a variable regulation and control lane, and finally the passing phases of the special lane and the variable regulation and control lane are controlled. And the emergency vehicle can be ensured to rapidly pass at a high speed per hour when driving into the buffer area. According to the method, the efficiency and the safety of emergency traffic are effectively improved by accurately controlling the intelligent signal lamp and combining the lane queue length and passing phase calculation.

    本发明涉及一种智能网联环境下基于交叉口动态车道的紧急车辆控制方法,属于应急交通管控领域。该方法包括宏观规划和微观控制两部分。宏观规划部分通过A*算法规划出紧急车辆到事故点的最优路径,并确定每个交叉口的交通组织方法。微观控制部分则通过车路协同技术,将交叉口划分为正常行驶区、缓冲区和冲突区,利用路侧控制单元为紧急车辆规划专用车道,然后调控专用车道中其他车辆变道进入可变调控车道,最后控制专用车道和可变调控车道通行相位,确保紧急车辆在驶入缓冲区时能保持较高时速快速通行。该方法通过对智能信号灯的精确控制,结合车道队列长度和通行相位计算,有效提高了应急交通的效率和安全性。
