摘要： 针对相邻连续T型路口非直线路径的协调控制问题，基于MULTIBAND模型，研究了不同路径类型和干扰相位对协调控制性能的影响，通过将相邻转向路口的左转单环信号耦合得到虚拟路口的双环信号并将其嵌入协调模型，间接将非直线路径转化为直线路径处理。采用VISSIM仿真平台，对桂林市解放桥周边路网进行模拟实验。仿真数据研究结果表明：被控制路径在三种交通流状态下行程延误分别减少了22.27%、14.64%、13.72%，停车延误分别减少了26.09%、17.19%、15.81%；所提出的控制方法不仅能减少系统延误，同时也能显著降低被控制路径的延误和停车概率，并且能够适应不同程度的潮汐流，验证了该方法的科学性和适用性。

Abstract: Aiming at the coordinated control problem of non-straight paths at adjacent continuous T-shaped intersections, based on the MULTIBAND model, the effects of different path types and disturbance phases on the coordinated control performance were studied. By coupling the left-turn single-loop signal of the adjacent turning intersections, the double-loop signal of the virtual intersection was obtained and embedded in the coordination model, which indirectly converted the non-straight path into a straight path to process. The VISSIM simulation platform was used to simulate the road network around Jiefang Bridge in Guilin. The simulation data research results show that under the three traffic flow conditions, the travel delay of the controlled route is reduced by 22.27%, 14.64%, and 13.72% respectively, and the parking delay is reduced by 26.09%, 17.19%, and 15.81% respectively. The proposed control method can not only reduce the system delay, but also significantly reduce the delay and parking probability of the controlled path, and can adapt to different degrees of tidal flow, which verifies the scientificity and applicability of the proposed method.
