The invention discloses a dynamic self-adaptive green wave method based on vehicle-road collaboration. After vehicles drive into a signal detection range of an intersection signal control machine, vehicle-mounted terminals transmit vehicle information to the intersection signal control machine in a vehicle advancing direction; a roadside communication device receives the vehicle information and screens the vehicle information; after screening, the roadside communication device calculates an average speed of all vehicles in a certain time period, calculates a phase difference of the vehicles passing through the road section, and transmits the phase difference to an intersection signal control machine located at a next intersection; and the intersection signal control machine at the next intersection adjusts a street lamp time interval of the intersection according to the phase difference. The dynamic self-adaptive green wave method based on vehicle-road collaboration has the advantagesthat: firstly, the direction of large flow is determined according to flow information obtained through vehicle-road collaboration, and therefore a green wave route is switched to; secondly, the average vehicle speed is calculated according to the vehicle speeds obtained through vehicle-road collaboration, and therefore the green wave phase difference is configured; and thirdly, all-weather coverage of dynamic self-adaptive green waves in a vehicle-road collaboration mode is achieved.
本发明公开了一种基于车路协同的动态自适应绿波方法,车辆行驶到路口信号控制机信号检测范围后,车载终端向车辆行进方向的路口信号控制机,发送车辆信息,路侧通信装置接收到车辆信息进行筛选,筛选后,再计算在某一时段的所有车辆平均车速,计算车辆行驶过该路段的相位差,并发送给位于下一路口的路口信号控制机,下一路口的路口信号控制机根据相位差,对路口的路灯时间间隔进行调节。本发明所述的一种基于车路协同的动态自适应绿波方法,一是通过车路协同获得的流量信息,确定大流量方向,从而切换绿波路线;二是通过车路协同获得的车辆速度,计算平均车速,从而配置绿波相位差;三是车路协同模式下的动态自适应绿波的全天候覆盖。
