Abstract To solve the car-following problem of intelligent and connected vehicle (ICV), a car-following model of ICV was proposed, and the model properties were analyzed. Considering the carfollowing property of variable headway, the ICV car-following model was proposed to maintain simple model structure and clear physical meaning of model parameters. Based on the function of spacing and speed at equilibrium state, the flow-density function curve of the proposed ICV car-following model was calculated. The mechanism of improving traffic capacity by the proposed ICV car-following model was also analyzed. From the perspective of microcosmic kinematics, the stability criterion of the proposed ICV car-following model was theoretically derived. The results show that according to the proposed ICV car-following model, the maximum capacity can be obtained with the density of 66.887 2 car·km-1 and the speed of 63.576 0 km·h-1. The model stability criterion is related with traffic flow speed and can be stable at any speed, which shows that the model has good model stability condition.
