The invention provides a variable lane control method based on space-time coordination, the flow direction and flow of an intersection can be pre-judged, and intersection variable lane release switching is prepared in advance so as to avoid intersection imbalance or reduce intersection imbalance time and improve the overall passing efficiency of the intersection. In the technical scheme of the invention, the vehicle number is converted into the length based on the vehicle type; the method is based on a path relationship between a to-be-monitored road section and each upstream lane, and calculation is performed by combining historical lane state data to obtain a vehicle flow ratio of an upstream lane entering a variable lane entrance of the to-be-monitored road section; the steering vehicleflow ratio of vehicles entering the entrance of the variable lane is calculated, the vehicle flow in each driving direction on the to-be-monitored road section is estimated in advance, the vehicle flow is added to obtain the vehicle flow which may need to be processed in each driving direction on the to-be-monitored road section and compared with the vehicle flow which can be processed by the lane, and the steering direction is found; meanwhile, the invention further discloses a variable lane control system based on space-time coordination.
本发明提供一种基于时空协同的可变车道控制方法,其能够预判路口流向流量,提前准备路口可变车道放行切换,进而可避免路口失衡或减少路口失衡时间,提升路口的总体通行效率。本发明技术方案中,将车辆数基于车辆类型转换为长度,基于待监测路段与各个上游车道的路径关系,结合历史车道状态数据进行计算,得到上游车道进入待监测路段的可变车道进口的车辆流量比,以及计算进入可变车道进口的车辆的转向的车辆流量比,预先估算待监测路段上每个行驶方向的车流量,相加后得到待监测路段上每个行驶方向的可能需要处理的车流量,然后与车道可以处理的车流量进行比较,进而找到转向方向;同时本发明也公开了一种基于时空协同的可变车道控制系统。
