本文主要研究在周期边界条件下，换道行为对双车道交通流稳定性的影响。在描述了两个车辆群的最优速度模型并推导了它们的稳定性条件之后，将反馈信号引入到最优速度模型中，该反馈信号包含了作用于双车道交通系统的来自两个车道的车辆的信息。控制信号只有在交通状态处于拥挤状态时才能起到缓解交通拥挤的作用，而在交通状态处于稳定状态时，控制信号的作用将消失。数值仿真结果表明，换道行为会破坏双车道交通流的稳定状态，加剧交通扰动，但该控制方法最终能成功抑制交通拥堵，表明本文的结论具有一定的理论和实际意义。
This paper deals mainly with the influence of lane changing behaviours on the stability of two-lane traffic flow under a periodic boundary condition. Following the description of an optimal velocity model for two vehicle groups and the derivation of their stability conditions, the feedback signals, which involve information about vehicles from both lanes acting on the two-lane traffic system, are introduced into the optimal velocity model. The control signals play a role in alleviating the traffic jam only if the traffic state is in congestion, and their role will vanish if the traffic state is in the steady state. The numerical simulations show that lane changing behaviours can break the steady state of two-lane traffic flow and aggravate the traffic disturbance, but the control method would successfully suppress the traffic jam eventually, which implies that the conclusions obtained here have certain theoretical and practical significance.
