Abstract:

The most current researches on the coordination control for intelligent and connected vehicle (ICV) at unsignalized urban intersections assume a 100% market penetration rate of ICV without consideration of the effects of human driven vehicle (HDV) on the system. This paper aims at resolving the coordinative control problem at unsignalized intersections under mixed traffic condition with HDVs and ICVs coexist, and exploring the effects of ICV penetration rate on system performance. Firstly, a reservation-based hierarchical platoon control framework is proposed, in which, the top layer assigns the intersection crossing moment for each vehicle and the bottom layer is in charge of execution and speed trajectory planning. Then the control and scheduling strategies of ICV and HDV are formulated respectively based on platoon reservation way. Finally, a comparative simulation is performed under different ICV penetration rates and traffic flows. The results show that under an ICV penetration rate of 10% to 100% and a traffic flow of 400 to 1 000 vehicles per hour, the proposed method can effectively enhance the traffic efficiency and reduce the average fuel consumption of vehicles, compared with actuated traffic light control strategy.
