Abstract: It is exciting that connected and automated vehicles are coming to us. While it has great potential, full benefits can only be realized with 100% connected automated vehicles. Thus, it is important to realize as much benefit as possible during the transition period (i.e., mixed traffic of connected, automated, and human-driven vehicles. This talk will present the development of cooperative platooning algorithms for mixed traffic of connected automated vehicles and conventional human-driven vehicles. The recent development of connected and automated vehicle technology allows a group of such vehicles to travel closely one after another in a safe manner (known as, cooperative platooning), which greatly improves mobility and energy efficiency. However, when a human-driven vehicle exists within the group, the cohesion of the vehicle platoon is not possible, due to uncertain human driver behavior. The proposed algorithms enable connected and automated vehicles to safely follow human-driven vehicles at shorter headways while mitigated traffic disturbances. These algorithms will also be able to assist a human driver in the connected-but-not-automated vehicle by complementing human’s imperfect behaviors. As such, the cooperative platooning can be efficiently operated at low market penetration of connected automated vehicles. This talk will also discuss challenges in identifying preceding vehicles to form cooperative planning.
