In this paper,we present a new car-following model by taking into account the effects of the traffic interruption probability on the car-following behaviour of the following vehicle.The stability condition of the model is obtained by using the linear stability theory.The modified Korteweg-de Vries(KdV) equation is constructed and solved,and three types of traffic flows in the headway sensitivity space—stable,metastable,and unstable—are classified.Both the analytical and simulation results show that the traffic interruption probability indeed has an influence on driving behaviour,and the consideration of traffic interruption probability in the car-following model could stabilize traffic flow.
In this paper, we present a new car-following model by taking into account the effects of the traffic interruption probability on the car-following behavior of the following vehicle. Stability condition of the model is obtained by using the linear stability theory. modified Korteweg-de Vries (KdV) equation is constructed and solved, and three types of traffic flows in the headway sensitivity space-stable, metastable, and unstable-are classified. Both the analytical and simulation results show that the traffic interruption probability substantially has an influence on driving behavior, and the consideration of traffic interruption probability in the car-following model could stabilize traffic flow.
