  Connected and Automated Vehicle Support Services

The Connected and Automated Vehicle (CAV) Support Services provide infrastructure owner operators (IOOs), equipment manufacturers, and device vendors with technical assistance and equipment loans during CAV deployments. By providing knowledge and equipment, the services advance CAV deployments without any cost for users. We provide support to all levels of users, including IOOs interested in testing CAV technologies as they consider deployment, vendors interested in bench testing time and space at the Turner-Fairbank Highway Research Center, and organizations in the later stages of CAV deployment, such as the Connected Vehicle (CV) Pilot Sites.
