本文提出了双车道网格交通流的统一模型，并比较了各种网格水动力模型的不同效果。线性和非线性分析结果表明，多重密度差效应（MDDE）在双车道系统中扩大稳定区域的作用最强。其次是密度差效应（DDE）、多重通量差效应（MFDE），最后是通量差效应（FDE）。但当密度在0.25左右时，MFDE比DDE更能扩大稳定区域。原因是较小的流量值可能对应于轻流量或重流量。还分析了能源消耗和交通排放，并显示其与线性和非线性分析结果具有相同的编组序列。数值模拟验证了理论分析。而这也是符合现实的。
In this paper, a unified model is presented for two-lane lattice traffic flow, with comparing different effects in the various lattice hydrodynamic models. Results of linear and nonlinear analysis show that multiple density difference effect (MDDE) is the strongest to enlarge the stable region in two-lane systems. Followed by density difference effect (DDE), multiple flux difference effect (MFDE), and finally flux difference effect (FDE). But when density is around 0.25, MFDE is better to enlarge the stable region than DDE. The reason is that a small flow-rate value might correspond to either a light traffic or a heavy traffic. Also energy consumption and traffic emissions are analyzed and shown to be the same marshaling sequence as linear and nonlinear analysis results. Numerical simulations validate theoretical analysis. And this is consistent with the realistic.
