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.
2023 Summer Meeting: The TFTC (ACP50) Summer Meeeting was held at the AMS Institute, July 26-28, 2023 in Amsterdam, NL. Click here to see the committee meeting agenda. A selection of abstracts related to data were invited for submission to a special issue of Data Science for Transportation Journal.
2023 Annual Meeting: The TFTC (ACP50) committee met

TFTC Centennial Paper The Committee on Traffic Flow Theory and Characteristics (ACP50) prepared and submitted a paper to mark the passage of the TRB centennial. This paper is the result of special efforts of the committee members to capture the current state of the art and practice and the perspectives on future directions in the areas of focus.
Subcommittees
Traffic Flow Modeling for Connected and Automated Vehicles subcommittee– ACP50 (3)
The ACP50-3 Subcommittee is a sub-committee of the Transportation Research Board (TRB) Traffic Flow Theory and Characteristics (ACP50) Committee. The subcommittee was created in January of 2015 at the ACP50 Committee meeting at the Transportation Research Board Annual Meeting (Washington DC, USA). It was named the Subcommittee on “Traffic Flow Modeling of Connected and Automated Transportation Systems”. The name was later changed to the Subcommittee on “Connected and Automated Traffic Flow (CAT-Flow) ”. Since then, the subcommittee has been successfully organizing multiple TRB Annual Meeting workshops/sessions and Automated Vehicle Symposium (AVS) events among other activities/conferences/meetings/special calls for papers. The subcommittee members and friends are continuously representing our ACP50 Community in different initiatives/organizations while strengthening the ties between industry representatives and researchers from our traffic flow community.
Large-scale Multimodal Traffic Modeling and Mobility Services– ACP50 (4)
Consider getting involved in this subcommittee (ACP50 (4)), which is chaired by Ali Zockaie (Michigan State) and Jack Haddad (Technion Israel). 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 670 papers to 69 issues of the Transportation Research Record (previously Highway Research Record). These papers have been cited more than 30,000 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 28,000 times according to Google Scholar (thanks to V. Gayah).
We look forward to your active participation and involvement with this committee. Very sincerely yours,
Dr. Ludovic Leclercq, Committee Chair
