Abstract:Cooperative driving automation aims to improve the safety and flow of traffic and facilitate road operations by supporting the movement of multiple vehicles in proximity to one another. This outcome is accomplished by sharing information that can be used to influence dynamic driving tasks directly or indirectly by one or more nearby road users. Vehicles and infrastructure elements engaged in cooperative driving automation may share information, such as state (e.g., vehicle position, signal phase) or intent (e.g., planned vehicle trajectory, signal timing), or they may seek agreement on a plan (e.g., coordinated merge). Cooperation among multiple participants in traffic can improve safety, mobility, situational awareness, and operations. For Integrated Highway Prototype 2 (IHP2), three key feature groups included cooperative lane follow (platooning and cooperative adaptive cruise control), cooperative lane coordination (cooperative lane change, merge, and weave), and cooperative traffic management (speed and gap control, lane assignment, and queue management). The combination of these feature groups to form IHP2 provides benefits to both the individual traveler and the overall traffic system.
