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.

Subcommittees
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 17,000 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 18,000 times according to Google Scholar (thanks to V. Gayah).
NEW TRR 2018 Accepted Papers: The list of 24 papers accepted by AHB 45 for publication in 2018 TRR issues is announced. Click here to check the list. This list will be updated once we get the DOI data for the papers.

Free Traffic Flow Webinars: Since 2010 we have hosted 68 free Traffic Flow Theory and Characteristics Webinars. From 2010-2011, this was done in partnership with the TrafficLab at Georgia Tech. If you have a topic to suggest or you would like to present a webinar, please contact us.

2018 TRB Annual Meeting: Click here for a quick summary of our meetings, sessions, and workshops that were held during the TRB Annual Meeting, January 7-11, 2018 in Washington, D.C.

2018 Summer Meeting will be held in conjunction in Woods Hole, MA from August 7-9, 2018. Extended Abstracts and Classic Paper Contributions are due on April 15, 2018!

Greenshields Prize: The 2018 Greenshields Prize will be announced at the Summer Meeting in Woods Hole in August 2018.

Best Paper in Traffic Flow Theory Award: The 2018 Best Paper in Traffic Flow Theory Award will be announced at the Summer Meeting in Woods Hole in August 2018.

ISTTT 23: The 23rd International Symposium on Transportation and Traffic Theory will be held on the campus of Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland from July 24-26, 2019. We will also hold a short summer meeting at the Symposium.

We look forward to your active participation and involvement with this committee. Very sincerely yours,

Dr. Soyoung Ahn, Committee Chair
University of Wisconsin Madison
