The invention belongs to the field of self-organizing networks of automatic driving vehicles, and particularly relates to an intersection centralized control method of an intelligent traffic system based on a vehicle-mounted adaptive network. According to the invention, measures can be taken in time when the vehicle is delayed, and unlimited waiting of a controller is avoided. Lane changing behaviors are allowed in consideration of vehicles which change lanes after entering an intersection area. In consideration of emergency vehicles, the vehicles are ensured to pass through the intersection preferentially. and vehicle priorities are set, and a vehicle passing sequence is controlled according to the lane weights. According to the method, the vehicles can be allowed to pass through the intersection without any conflict, priority scheduling of the vehicles with high priorities and optimal scheduling according to different strategies such as the total waiting time of the vehicles are achieved, meanwhile, it is guaranteed that the emergency vehicles pass through the intersection preferentially, and more importantly, other vehicles can be allowed to continue to advance while congestionand accidents happen. The method provides a solution and favorable support for intersection traffic control and scheduling in an intelligent traffic system environment.
本发明属于自动驾驶车辆自组织网络领域,具体涉及基于车载自适应网络的智能交通系统交叉口集中控制方法。本发明能够在车辆延误的时候及时采取措施,避免了控制器的无限制等待。考虑到了进入交叉口区域后变道的车辆,允许变道行为。考虑到应急车辆,保证这类车辆优先通过交叉口。设定车辆优先级,根据车道权重控制车辆通行顺序。本发明能够允许车辆无任何冲突地穿过交叉口,实现了高优先级车辆的优先调度以及根据车辆总等待时间等不同策略的优化调度,同时保证了应急车辆优先通过交叉口,更重要的是能够允许其他车辆在拥堵、事故发生的同时继续前进。为智能交通系统环境下的交叉口交通控制和调度提供了解决方案和有利支撑。
