Transportation infrastructure systems serve as the platform for emerging
automated vehicle (AV) technologies and, in their current condition, limit the
reliability of these new vehicles. Road conditions, lane markings, and signs
provide essential guidance and information to both human- and machine-controlled
vehicles; however, their condition and placement vary depending on local
conditions, practices, and funding. Irregular sign placements and road markings
confuse both human and machine drivers and can create unsafe conditions. Still,
in the short term, they are the easiest factor to adjust regarding successful AV
deployment.
Automated Vehicles and Infrastructure Enablers: Pavement Markings and
Signsexamines the issues associated with pavement markings and signs
in the context of advanced automation. The report focuses on unresolved issues
between the AV industry and infrastructure owners and operators and provides
opportunities and recommendations for the AV industry and the larger
transportation community to address reliability issues.
