| Abstract: | In this paper, a new cooperative driving lattice model of traffic flow is proposed for two lane freeway. The linear stability analysis and nonlinear analysis near the critical point is carried out to demonstrate that our consideration is reasonable. The theoretic analysis validates that the stability of traffic flow is improved by considering the information of more than one site ahead. Numerical simulation further testifies that the traffic jam can be suppressed efficiently with the consideration of the information of cooperative driving lattices under lane changing case. |
