The invention discloses a dynamic cooperative confluence control method and system suitable for a mixed traffic flow, and the method comprises the steps: firstly determining a target control state and an optimal formation scheme, then determining the control time of cooperative vehicles and the start and end time of a gap formed by the cooperative vehicles, and transmitting a deceleration instruction to the cooperative vehicles when the control time arrives, the traffic flow of the main line forms a divided motorcade and a gap which can be used by vehicles on the ramp; and for each ramp vehicle, according to the planned cooperative vehicle distribution and control time, an appropriate gap for the ramp vehicle to merge into the main line is determined, and the driving speed is planned for the ramp vehicle through the optimization model. According to the technical scheme, the macroscopic traffic flow theory and the microcosmic vehicle control are combined, the behaviors of the main line and ramp vehicles are optimized at the same time, the method can adapt to a mixed traffic flow scene with the flow dynamically changing, efficient and safe ramp confluence is guaranteed, and therefore the traffic performance and safety are improved, tail gas emission is reduced, and the economic benefit is improved. And more efficient, safer and sustainable traffic operation is realized.

    本发明公开一种适用于混合交通流的动态协作合流控制方法及系统,首先确定目标控制状态及最优编队方案,然后明确合作车辆的控制时间及其所形成间隙的始末时间,并在控制时间到达时向合作车辆发送减速指令,主线的交通流形成被分割开的车队和可供匝道车辆利用的间隙;针对每一辆匝道车辆,根据已经规划好的合作车辆分布和控制时间,确定其汇入主线的合适间隙,并通过优化模型为其规划行驶的速度。此种技术方案结合宏观交通流理论与微观车辆控制,同时对主线和匝道车辆的行为进行优化,能够适应流量动态变化的混合交通流场景,保证高效安全的匝道合流,从而提高交通性能和安全并减少尾气排放,实现更加高效、安全和可持续的交通运行。
