The Transportation Research Board (TRB) is organising the 100th Annual Meeting, which will be held online throughout January 2021. The meeting program will cover 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 will focus on the spotlight theme for the 2021 meeting: Launching a New Century of Mobility and Quality of Life. This year’s meeting also will feature dozens of sessions on how COVID-19 has impacted transportation and how transportation professionals and researchers are responding.
