Abstract

Owing to the real traffic in which the drivers' sensitivities are different under different speeds and road conditions, a modified car-following model is put forward. This model is related to the headway of cars and the velocity difference as well as the variation of the sensitivity. A small parameter is added to the original sensitivity. Based on the stability theory of Hurwiz, the allowable variation range of this parameter, especially in the case of different velocities, is obtained. It can be concluded that the model with the term of velocity difference can increase the stability of traffic flow.
