通过引入合理的换道规则,将单车道反馈控制模型扩展成双车道交通流模型.数值仿真表明,与经典的优化速度双车道模型相比,由于引入适当的反馈控制信息,车辆速度波动变小或消失,系统不会出现严重的堵塞现象.这说明该双车道反馈控制模型能有效地抑制或缓解交通流堵塞.
In this paper we extend the single-lane feedback control model to the two-lane case, named as the two-lane optimal velocity feedback control (OVFC) model. Compared with the two-lane optimal velocity model, simulation results indicate that no serious traffic jams occur in the OVFC system when the feedback signal is introduced, and the oscillation of velocity becomes weaker or vanishes. This means that the two-lane OVFC model can suppress the traffic jams effectively.
