A new lattice model of traffic flow with the consideration of the drivers' aggressive characteristics

In real traffic, aggressive driving behaviors often occurs by anticipating the front density of the next -nearest lattice site at next time step to adjust their acceleration in advance. Therefore, a new lattice model is put forward by considering the driver's aggressive effect (DAE). The linear stability condition is derived from the linear stability theory and the modified KdV equation near the critical point is obtained through nonlinear analysis with the consideration of aggressive driving behaviors, respectively. Both the analytical results and numerical simulation indicate that the driver's aggressive effect can increase the traffic stability. Thus driver's aggressive effect should be considered in traffic lattice model. (C) 2016 Elsevier B.V. All rights reserved.
