摘　　要：针对多个车辆和道路之间的决策协调困难,交叉路口交通流控制存在实时性不佳的问题,提出基于多车信息交互的交叉路口交通流实时控制方法。基于误差耦合方法,完成交叉路口交通流车辆定位。通过压缩感知方法和V2V通信技术,将获取的车辆定位数据与其他传感器采集的信号数据发送至其他车辆,实现多车信息交互,并获取通过该交叉路口的车辆数据信息。采用信号配时优化方法实现交叉路口交通流实时控制。实验结果表明,所提方法获取的车辆轨迹定位结果误差较小,重构后的车速传感器信号与原始信号最为接近,最大排队长度仅为36 m,最高停车率为50.5%,最大绿信比为0.68,说明所提方法的交叉路口交通流实时控制效果好。Aimed at the difficulty of decision coordination between multi-vehicle and roads and the problem of poor real-time traffic flow control at intersections,a real-time traffic flow control method at inter sections based on multi-vehicle information interaction is proposed.Based on the error coupling method,the vehicle positioning of intersection traffic flow is completed.Through the compressed sensing method and V2V communication technology,the acquired vehicle positioning data and signal data collected by other sensors are sent to other vehicles to realize multi-vehicle information interaction and obtain vehicle data information passing through the intersection.The real-time control of traffic flow at intersections is realized by signal timing optimization method.The experimental results show that the error of vehicle trajectory positioning obtained by the proposed method is smaller,and the reconstructed speed sensor signal is the closest to the original signal.The maximum queue length is 36 m,the highest parking rate is only 50.5%,and the maximum green time ratio is 0.68,which indicates that the proposed method has good real-time control effect on traffic flow at intersections.
