Moreover, in order to introduce the approach to analyze the stability, taking the full velocity difference (FVD) model for example, the local and asymptotic stability analysis is discussed, while the corresponding nonlinear analysis is also conducted. Then, some perspectives of the car following model are given in the final.展开更多
