2021 TRB Presentations

Transportation Research Board Annual Meeting

The Transportation Research Board (TRB) provides leadership in transportation improvements and innovation through trusted, timely, impartial, and evidence-based information exchange, research, and advice regarding all modes of transportation. For example, committees, researchers, and staff are currently focused on advancing resilient infrastructure, exploring transformational technology, and caring for the public’s health and safety.

The TRB Annual Meeting is the largest global gathering of transportation professionals and researchers with a focus on innovative solutions for all modes of transportation.

Every January, transportation researchers from around the world gather in Washington, D.C. for this premier transportation conference. More than 14,000 policy makers, administrators, practitioners, researchers, and representatives of government, industry, and academic institutions attended the 99th Annual Meeting in January 2020 to discover the latest innovations. Twenty twenty-one was different in that it was an all virtual event due to the worldwide COVID pandemic. 

Researchers from the Alabama Transportation Institute exhibited a strong presence at the 2021 conference. ATI researchers were involved in 26 separate presentations. 

ATI researchers also participate heavily in TRB Standing Committees. Almost all serve as a member or friend on several of the various committees.
