Transportation Research Board AHB45
Committee on Traffic Flow Theory and Characteristics



Operations Section

Welcome to the home page of the TRB Committee on Traffic Flow Theory and Characteristics.

This volunteer TRB committee is concerned with the development, validation, and dissemination of theoretical, experimental, and applied research on traffic flow theory and traffic flow characteristics and the determination of the relationship of traffic flow theory and traffic flow characteristics to the planning, design and operation of transportation systems.

Joint Simulation Subcommittee (SimSub)

We jointly sponsor the TRB Joint Simulation Subcommittee AHB45(1), chaired by George List (North Carolina State University). SimSub is the focal point for coordinating advancements in traffic simulation which crosses multiple committee boundaries. You can volunteer in one of SimSub's task groups: Annual Workshop; Liaison and Outreach; Newsletter; Research Needs and Resources; Simulation Calibration; Verification and Validation; Mesoscopic Simulation; Safety Modeling and Simulation; or Agent-Based Simulation.

Crowd Flow Dynamics, Modeling and Management Subcommittee

Consider getting involved in this subcommittee (AHB45(2)), which is chaired by Serge Hoogendoorn (TU Delft) and Majid Sarvi (Monash University). Follow our Facebook page, and join us for our annual workshop and committee meeting in January at the TRB Annual Meeting.

TRB Publications: Since 1963 the Committee on Traffic Flow Theory & Characteristics has contributed 619 papers to 66 issues of the Transportation Research Record (previously Highway Research Record). These papers have been cited more than 13,000 times according to Google Scholar (thanks to E. Xuan). We invite your comments on these papers—how have they influenced research or practice? Do you cite them? The International Symposium on Traffic and Transportation Theory (ISTTT) has produced 645 papers since 1959, that have been cited more than 14,000 times according to Google Scholar (thanks to V. Gayeh).

Free Traffic Flow Webinars: Since 2010 we have hosted more than 40 free Traffic Flow Theory and Characteristics Webinars. From 2010-2011, this was done in partnership with the TrafficLab at Georgia Tech. You can join the Traffic Flow Webinar Google Group to make sure you are notified and also be sure to follow us on Facebook. If you have a topic to suggest or you would like to present a webinar, please contact us.
