Abstract: The density difference memory integral (DDMI) term can be applied to describe traffic density information of the driver’s historical memory during a continuous period of time. In this paper, a new lattice model is provided with the consideration of the DDMI effect for two-lane freeway. The linear stability condition of two lanes has been derived by considering the DDMI effect through linear stability theory, which shows that the DDMI effect can improve traffic stability under lane changing. According to the observation of simulation, the DDMI effect conduces to the stability of traffic flow for two-lane freeway.
