Integrated Highway Prototype Using Cooperative Driving Automation (CDA)

Connectivity helps automated vehicles safely merge and then harmonize across a traffic stream. The Federal Highway Administration's (FHWA's) integrated highway prototype used up to five SAE International® Level 2+ vehicles on a closed track to perform platooning, cooperative merge, and speed harmonization maneuvers. The research team then analyzed the potential benefits of applying CDA to highways. Additionally, vehicles from a university collaborator helped demonstrate the viability of these maneuvers across diverse vehicle platforms, which will be key to successful operation of cooperative vehicle applications in the future.
