This study presents the potential benefits of cooperative adaptive cruise control (CACC) by deploying the technology in a platoon of three trucks. The project was designed to gauge the potential for CACC to improve heavy truck operations in the short term, the willingness of drivers to participate in CACC-enabled platoons with short time gaps between trucks, and the achievable energy savings at the preferred time gaps. CACC uses dedicated short-range communication (DRAC) (short-range to medium-range wireless communication channels designed for automotive use) and other technology components to enable vehicles to “talk” to each other. The technology was evaluated in simulation scenarios and on closed tracks and public highways in various cities in California and Virginia, USA and Quebec, Canada during 2016 to 2017. Long-haul truck drivers were recruited for some of the road tests to gauge their comfort with various time gaps between the trucks and their overall confidence in the technology.
