Title:

Impacts of Automated Vehicles on Highway Infrastructure

Accession Number:

01763989

Record Type:

Component

Abstract:

This paper summarizes the results of a multiphase federally-funded research effort, which involved a comprehensive literature review, engagement with highway infrastructure owners and operators, and interviews with industry experts and key stakeholders to document the potential impact of automated vehicles (AVs) on highway infrastructure. The research attempted to identify the state of the practice among highway infrastructure owners/operators, any gaps in knowledge, and agency preparedness levels regarding the impacts of AV use on highway infrastructure. The operations or policy aspects of the AV infrastructure impacts were not covered. Four different categories of the physical roadway infrastructure were considered for this study, including the uniformity and quality of traffic control devices, the changing demands of intelligent transportations systems (ITS) devices, structural requirements for pavements and bridges, the effects on multimodal infrastructure (bike lanes and Complete Streets designs), and the potential need for other roadside infrastructure (e.g., guardrails and communications systems for roadway digital infrastructure). The research identified early strategies for design and maintenance of certain physical highway infrastructure elements that are believed to benefit AVs as well as human drivers.
