Impacts of Automated Vehicles on Highway Infrastructure

This report presents the results of a multiphase research effort, which involved a comprehensive literature review, engagement with highway infrastructure owners and operators (IOOs), and interviews with industry experts and key stakeholders to document the potential impact of automated vehicles (AVs) on highway infrastructure. The study attempts to identify the state of the practice among IOOs, gaps in knowledge, and agency-preparedness levels regarding the impacts of AV use on highway infrastructure. Operations or policy aspects of AV–infrastructure impacts are not covered. Several aspects of roadway infrastructure are considered for this study, including the quality and uniformity of traffic control devices, the changing demands of intelligent transportation systems, structural requirements for pavements and bridges, effects on multimodal infrastructure (e.g., bike lanes and Complete Streets designs), and the potential need for other roadside infrastructure (e.g., guardrails and communications systems for roadway digital infrastructure).
