本文提出了一种考虑交通中断概率影响的单车道高速公路交通流模型。通过线性稳定性分析得到了新模型的稳定性条件，通过非线性分析导出了修正的Korteweg-de Vries （KdV）方程。因此，空间将被划分为三个区域：稳定、亚稳和不稳定。仿真结果还表明，交通中断概率能够稳定交通流。
In this paper, we present a new lattice model which involves the effects of traffic interruption probability to describe the traffic flow on single lane freeways. The stability condition of the new model is obtained by the linear stability analysis and the modified Korteweg–de Vries (KdV) equation is derived through nonlinear analysis. Thus, the space will be divided into three regions: stable, metastable and unstable. The simulation results also show that the traffic interruption probability could stabilize traffic flow.
