To enhance further the stability of traffic flow, based on the FVD (full velocity difference) model,a new car following model named BL＆OVD model is proposed by incorporating the synergy effect of backward looking and optimal velocity difference information. By applying the linear stability theory, the linear stability condition of the new model is obtained and the modified Korteweg-de Vries (mKdV) equation is established with nonlinear analysis to describe the propagating behavior of traffic jam near the critical point. The simulation results show that the amplification of random disturbance signal in traffic flow can be reduced effectively with the new consideration, which means that the proposed approach can stabilize the traffic flow and suppress the traffic congestion. The new model can stabilize the traffic flow further, and help to design the vehicle driving strategy in the autopilot system.
