CAV technologies offer potentially transformative societal impacts—including significant mobility, safety, and environmental benefits. The Federal Highway Administration (FHWA) has led the development, research, and standards-making of these technologies, and is currently developing deployment approaches and guidance.
Repair and rehabilitation of the aging highway infrastructure continues to be a challenging endeavor for all U.S. highway agencies. Thousands of miles of highway pavements need rehabilitation, and many of these highways carry over 100,000 vehicles/day, including a large percentage of trucks. Extended lane closures must be avoided to prevent compoun
