The effects of drivers' aggressive characteristics on traffic stability from a new car-following model

摘要

In this paper, a new car-following model is proposed by considering the drivers' aggressive characteristics. The stable condition and the modified Korteweg-de Vries (mKdV) equation are obtained by the linear stability analysis and nonlinear analysis, which show that the drivers' aggressive characteristics can improve the stability of traffic flow. Furthermore, the numerical results show that the drivers' aggressive characteristics increase the stable region of traffic flow and can reproduce the evolution and propagation of small perturbation.
