Preparing for Connected and Automated Vehicles: Insights from North Carolina Transportation Professionals

The connected and automated vehicles (CAVs) that are expected to be increasingly common on U.S. roads in the coming decades offer potential benefits in safety, efficiency, and mobility; they also raise concerns related to equity, access, and impacts on land use and travel behavior, as well as questions about extensive data requirements for CAVs to communicate with other vehicles and the environment in order to operate safely and efficiently. We report on interviews with North Carolina transportation experts about CAVs and their implications for sustainable transportation that serves all travelers with affordable, safe, and dignified mobility that also produces fewer environment impacts (emissions to air, water, and land; resource consumption; land use changes). The data reveal great interest among transportation professionals about a CAV transition, but a lack of consensus on the state of play and necessary next steps. Concerns include impacts on planning practice; implications for land use, equity, and safety; and data security and privacy. The findings suggest that local, regional, and state agencies would benefit from clear technical guidance on how to prepare for CAVs and to engage with the public, given high interest about a coming CAV transition. Intense data requirements for CAVs and associated infrastructure, as well as the regulatory and policy tools that will be required, raise concerns about threats to data safety and security and argue for proactive action.
