The invention discloses a crossroad traffic light duration adaptive dynamic adjustment method, and relates to the field of machine learning and intelligent traffic control. Obtaining and calculating initial parameter values of the lane length of each fast traffic lane, the number of the lanes of each fast traffic lane, the number of the maximum vehicle nodes capable of staying on each fast traffic lane, the total time length of traffic lights, and the average passing time length of east-west vehicle nodes; after receiving the RSU broadcast message, the vehicle node approaching the intersection sends a response message to the RSU, and after receiving the response of the vehicle node, the RSU at the intersection retrieves a local vehicle node list of the RSU, and records and updates the local vehicle node list; calculating an east-west direction traffic light duration adjustment coefficient by taking red light lighting as a period; calculating a time length adjustment coefficient of the traffic lights in the south-north direction by taking red light lighting as a period; the traffic light duration of the crossroad is calculated and adjusted by taking the turn-on of the red light in the east-west direction as a period, and the purpose of optimizing the traffic efficiency of the crossroad and the area is achieved.
本发明公开了一种十字路口红绿灯时长自适应动态调整方法,涉及机器学习、智能交通控制领域,方法包括,获取并计算得到各快车道车道长度、各快车道车道数、各快车道可停留最多车辆结点数、红绿灯总时长、东西方向车辆结点平均通过时长的初始参数值;驶近路口的车辆结点接收到RSU广播报文后,向RSU发送应答报文,路口RSU在接收到车辆结点应答后,检索RSU本地车辆结点列表,并进行记录更新;以红灯亮起为一周期起始,计算东西方向红绿灯时长调整系数;以红灯亮起为一周期起始,计算南北方向红绿灯时长调整系数;以东西方向红灯亮起为一周期起始,计算调整十字路口红绿灯时长,实现优化路口和区域通行效率的目的。
