The Transportation Research Board (TRB) organised with great success the 100th Annual Meeting, which was held online throughout January 2021. The meeting program covered all transportation modes, addressing topics of interest to policy makers, administrators, practitioners, researchers, and representatives of government, industry, and academic institutions. A number of sessions and workshops  focused on the spotlight theme for the 2021 meeting: Launching a New Century of Mobility and Quality of Life. This year’s meeting also featured dozens of sessions on how COVID-19 has impacted transportation and how transportation professionals and researchers are responding.
