The Transportation Research Board (TRB) 99th Annual Meeting will be held January 11–16, 2020, at the Walter E. Washington Convention Center, in Washington, D.C. The information-packed program is expected to attract more than 13,000 transportation professionals from around the world. The meeting program will cover all transportation modes, with more than 5,000 presentations in over 800 sessions and workshops, addressing topics of interest to policy makers, administrators, practitioners, researchers, and representatives of government, industry, and academic institutions. The mobile app will provide users with access to all sessions, presentations, posters, abstracts, exhibitors & maps. Browse sessions by day, subject area, types, & speaker. Create your personalized ‘My Meeting’ calendar of events (synchronized with your online Interactive Program Planner). Find practical Annual Meeting information and stay informed on breaking news and special events. Before first use, you'll need to download the latest conference data. Afterwards, you can use most of the app offline – although updates will be available regularly before and during the Annual Meeting. This app is provided by the Transportation Research Board of the National Academies of Sciences, Engineering, and Medicine and is only accessible to registrants for the TRB Annual Meeting.
