自稳定效应反映了交通流中当前点阵的适应性变化。为了改善交通流，本文在双车道格子流水动力模型中加入了一个新的自稳定项。线性稳定性分析表明，无论是否发生换道，自稳定效应都能提高双车道的交通稳定性。从数值模拟的角度来看，自稳定效应增强了双车道修正格子水动力模型中交通流的稳定性。
Self-stabilization effect reflects the adaptive change of the current lattice in traffic flow. To improve traffic flow, a new self-stabilization term in this paper is inserted into lattice hydrodynamic model for two-lane freeway. It is shown that the self-stabilization effect can increase traffic stability on two lanes whether lane changing occurs or not according to linear stability analysis. In view of numerical simulation, the self-stabilization effect enhances the stability of the traffic flow in the modified lattice hydrodynamic model for two-lane freeway.
