| Abstract: | An improved two-lane traffic flow lattice model is proposed. The model introduces a new function to govern the flow shift between two lanes, and then eliminates the flaws of vehicle backward movement which may appear in existing lattice models. The sufficient and necessary conditions for keeping the model’s linear stability are derived. Numerical simulations which correctly reproduce the lane changing behavior induced by small disturbances are presented. |
