The invention relates to the technical field of intelligent traffic management and control, and discloses a CAV hierarchical multi-mode trunk line coordination control optimization method in a mixed traffic environment, and the method comprises the following specific steps: enabling a head vehicle CAV to communicate with a roadbed facility, judging the distance between the head vehicle CAV and an intersection, selecting track control or track and signal coordination control, and optimizing the trunk line phase coordination quantity; the offset of trunk line coordination is minimized, the number of red light parking times on the trunk line is reduced, and the global traffic efficiency is improved. Specifically, optimization control is carried out on three levels including a vehicle layer, a signal layer and a trunk line layer. The signal offset optimization quantity of the trunk line layer is transmitted to the signal layer, the signal layer properly adjusts the time length of the signal lamp according to the signal offset optimization quantity, and the vehicle layer further optimizes the driving track of the vehicle according to the adjusted time length of the signal lamp. Through coordination control of three levels, efficient passing of vehicles is achieved, the number of parking times caused by red lights is reduced to the maximum extent, traffic pauses caused by signal discordance are reduced, and the traffic efficiency is improved.

    本发明涉及智能交通管理与控制技术领域,公开了一种混合交通环境下CAV分层多模态干线协调控制优化方法,具体步骤如下:头车CAV与路基设施进行通信,判断与交叉口间距,选择轨迹控制或轨迹与信号协同控制,同时优化干线相位协调量,使干线协调的偏移量最小,降低干线上红灯停车次数,提高全局交通效率。具体分为车辆层、信号层和干线层三个层级进行优化控制。干线层的信号偏移优化量传递给信号层,信号层据此适当调整信号灯时长,车辆层再根据调整后的信号灯时长进一步优化行车辆的行驶轨迹。本发明旨在通过三个层级的协调控制,实现车辆的高效通行,最大限度地减少红灯引起的停车次数,减少因信号不协调造成的交通停顿,提高交通效率。
