Providing Traffic Control Device Information in a Connected and Automated Vehicle Environment

Tuesday, June 18, 2019 - 19:00

Traffic control devices (TCDs) play a critical role in delivering regulatory, warning, informational, and guidance information to drivers.  Transportation agencies devote considerable resources to support TCD installation and maintenance.  However, as connected vehicles develop and vehicle automation becomes a reality, the potential exists to replace or augment TCDs with a digital connection.  

This project investigated the development of a digital TCD (DTCD) data service, focusing on signs and pavement markings.  To do so, the research team investigated emerging wireless communications capabilities, identified infrastructure information needs of automated vehicles, reviewed Virginia Department of Transportation (VDOT) current TCD practices, and surveyed existing data service systems.
