The invention discloses an intersection intelligent management and control method based on vehicle-road cooperation and automatic driving. The method specifically comprises the steps that driving state information is uploaded to a cloud control center through a network communication system when an automatic driving vehicle arrives at the entrance end of a regulation and control region; a cloud control center calculates the optimal safe vehicle speed passing through the intersection through a speed decision-making method based on space-time gap dynamic distribution, and feeds back the optimal safe vehicle speed to the automatic driving vehicle; and the automatic driving vehicle adjusts the current vehicle speed according to the uniform acceleration or uniform deceleration motion, and afterthe current vehicle speed is adjusted to the optimal safe vehicle speed, constant-speed driving is kept until the automatic driving vehicle leaves the intersection. According to the invention, self-adaptive intelligent and refined management and control of the intersection are realized through the cloud control center, the traffic capacity of the road intersection can be improved, and traffic jamis relieved; and vehicles in all directions can pass through the intersection without stopping, the passing space of the intersection is fully utilized, vehicle delay is reduced, and the passing efficiency of the road intersection is improved.
本发明公开了一种基于车路协同与自动驾驶的交叉口智能管控方法,具体为:自动驾驶车辆到达调控区入口端时,通过网联通信系统将行驶状态信息上传至云端控制中心;云端控制中心通过基于时空间隙动态分配的速度决策方法计算出通过交叉口的最优安全车速,并将最优安全车速反馈给自动驾驶车辆;自动驾驶车辆再按匀加速或匀减速运动对当前车速进行调整,当调整至最优安全车速后保持匀速行驶,直至驶离交叉口。本发明通过云端控制中心使交叉口实现自适应智能化、精细化管控,能够提高道路交叉口通行能力,缓解交通拥堵;使各方向车辆能够不停车通过交叉口,充分利用交叉口通行空间,降低车辆延误,提高道路交叉口通行效率。
