本文提出了一个考虑最优速度的修正微观交通流模型。与以往的模型不同，在最优车速条件下考虑了驾驶员的反应能力和最大加速度。本文研究了最优速度项中的参数对旋转交通分岔的影响。此外，通过数值模拟实验计算了系统分岔的演化过程。此外，所提出的模型的线性稳定性分析。
In this paper, a modified microscopic traffic flow model accounting for the optimal velocity has been proposed. Different with previous models, drivers’ response ability and the maximum of accelerations are considered in the term of the optimal velocity. The effect of parameters in the term of the optimal velocity on bifurcations in the rotary traffic is studied here. Besides, the evolvement of bifurcations in the system is calculated by performing numerical simulation experiments. Moreover, the linear stability analysis of the proposed model is presented.
