本文扩展了一个双车道格子流体动力学交通流模型，考虑了驾驶员在感知多个最优电流差时的预期效应。基于所提出的模型，我们推导出解析的影响，驾驶员的预期多个最佳的电流差异的不稳定性的交通动态。绘制了相位图，讨论了多个最佳电流差检测中的预期效应对稳定区域的增强作用。通过数值模拟发现，密度波在临界密度附近的振荡随晶格数的增加而减小，随瞬态和稳态预测时间的增加而减小。仿真结果与理论分析吻合较好，表明在双车道格子模型中考虑驾驶员对多个最优电流差的预期，能有效地稳定交通流，抑制交通拥堵。
This paper extends a two-lane lattice hydrodynamic traffic flow model to take into account the driver’s anticipation effect in sensing the multiple optimal current differences. Based on the proposed model, we derive analytically the effect of driver’s anticipation of multiple optimal current differences on the instability of traffic dynamics. The phase diagrams have been plotted and discussed that the stability region enhances with anticipation effect in sensing multiple optimal current differences. Through simulation, it is found that the oscillation of density wave around critical density decreases with an increase in lattice number and anticipation time for transient and steady state. The simulation results are in good agreement with the theoretical analysis, which show that considering the driver’s anticipation of multiple optimal current differences in two-lane lattice model stabilizes the traffic flow and suppresses the traffic jam efficiently.
