本文提出了一种新的双车道格子水动力交通流模型，该模型考虑了驾驶员行为的攻击性或胆小性。通过线性稳定性分析，考察了驾驶员特性对交通流稳定性的影响。结果表明，无论是变道还是不变道，随着攻击性(胆小)驾驶员比例的增加，稳定性区域都显着增大(减小)。为了描述临界点附近密度波的传播行为，进行了非线性分析，得到了表示扭结-反扭结孤子的mKdV方程。此外，还研究了具有较强攻击性(胆小)驾驶员的预期参数对双车道交通流动力学稳定性的正(负)效应。仿真结果与理论结果一致，证实了驾驶员的特性在双车道交通系统中起着重要的作用。
In this paper, a new two-lane lattice hydrodynamic traffic flow model is proposed by considering the aggressive or timid characteristics of driver’s behavior. The effect of driver’s characteristic on the stability of traffic flow is examined through linear stability analysis. It is shown that for both the cases of lane changing or without lane changing the stability region significantly enlarges (reduces) as the proportion of aggressive (timid) drivers increases. To describe the propagation behavior of a density wave near the critical point, nonlinear analysis is conducted and mKdV equation representing kink–antikink soliton is derived. The effect of anticipation parameter with more aggressive (timid) drivers is also investigated and found that it has a positive (negative) effect on the stability of two-lane traffic flow dynamics. Simulation results are found consistent with the theoretical findings which confirm that the driver’s characteristics play a significant role in a two-lane traffic system.
