考虑驾驶员对交通中断概率的预期效应，提出了一种新的格点模型。通过线性稳定性分析，得到了扩展模型的稳定性条件，表明驾驶员对交通中断概率的预期效应可以扩大交通流的稳定区域。通过非线性分析，导出了修正的Korteweg-de弗里斯（KdV）方程的扭结-反扭结孤子解，该解能描述共存相位.仿真结果还表明，驾驶员对交通中断概率的预期效应可以起到稳定交通流的作用。
In this paper, a new lattice model is proposed by considering the driver’s anticipation effect of traffic interruption probability. The stability condition of the extended model is obtained by the linear stability analysis, which shows that the driver’s anticipation effect of traffic interruption probability can enlarge the stable area of traffic flow. The kink–antikink soliton solution of the modified Korteweg–de Vries (KdV) equation is derived from nonlinear analysis, which can describe the coexisting phase. The simulation results also show that driver’s anticipation effect of the traffic interruption probability could stabilize traffic flow.
