摘要：
To explore the characteristics of mixed traffic flow with platoons of intelligent connected vehicles, a mathematical analytical expression that can reflect the random distribution characteristics of different types of vehicles in mixed traffic flow is proposed. Considering the dynamic characteristics of desired headway changing with speed, the car-following model of different types of vehicles was established. Based on this, the fundamental diagram of the mixed traffic flow with intelligent connected vehicle platoons was derived. Moreover, the sensitivity analyses of the market penetration rate of connected vehicles and the maximum platoon size were made. The simulation results show that the traffic capacity is gradually improved with the increase of the market penetration rate p. When p<0.3, the improvement of capacity is not significant as the market share increases. When p>0.5, the improvement of capacity is significant as the market share increases. In addition, with the increasing popularity of intelligent connected vehicles, the impact of the platoon size on traffic capacity becomes more and more significant. Meanwhile, the platoon size should be maintained between 4 and 6 when p<0.5, and the larger platoon size is recommended when p is nearly equal to 1. © 2020, Editorial Department of Journal of Southeast University.
