چکیده
( a Department of Civil Engineering, Tsinghua University, Beijing 100084, China) Abstract: Considering high speed following on expressway or highway, an improved car-following model is developed in this paper by introducing variable safety headway distance. Stability analysis of the new model is carried out using the control theory method. Finally, numerical simulations are implemented and the results show good consistency with theoretical study. Re śume :́ A l’égard du phénomène de car-following , c’est-à-dire la suite de voiture, à grande vitesse sur l’autoroute, cet article présente un modèle car-following basé sur la distance de sécurité minimum de variable . Ensuite, l’analyse de la stabilité du nouveau modèle en utilisant la théorie de la commande est effectué, suivie par un grand nombre d’expérimentations simulées mises en oeuvre. Enfin, les résultats montrent que l’étude théorique du nouveau modèle est correcte.
