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

This 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.

SimSub: Our committee is one of seven committees to jointly sponsor the Simulation Sub-Committee AHB45(1):

Committee Chair SimSub Liaison
AHB45 Traffic Flow Theory and Characteristics R. Bertini G. List, Chair
AHB40 Highway Capacity and Quality of Service L. Elefteriadou A. Skabardonis
AHB20 Freeway Operations P. Masters P. Prevedouros
AHB25 Traffic Signal Systems L. Head B. Park
ADB30 Transportation Network Modeling S. Peeta H. Liu
AHB55 Work Zone Traffic Control G. Ullman R. Benekohal
ADC20 Transportation and Air Quality J. Lin Y. Chiu

Historic Publications: Since 1963 the Committee on Traffic Flow Theory and Characteristics (and its predecessor committees) have contributed 497 papers to 57 issues of the Transportation Research Record (previously the Highway Research Record). Please take a look at this record over the past 49 years by following the links. Thanks to Ethan Xuan of U.C. Berkeley for this effort. We invite your comments on these papers—how have they influenced research or practice? Do you cite them?

Greenshields Prize: We have launched our Greenshields Prize best paper award and have selected the inaugural winner!

NEW: TRB Traffic Flow Theory and Characteristics Information Resource Center: TRB has launched new committee-specific web portals, take a look and let us know what you think!

ISTTT 20: The 20th International Symposium on Transportation and Traffic Theory will be held at the Grand Hotel Huis ter Duin in Noordwijk, the Netherlands, from July 17-19, 2013. The Symposium will be organized by the Delft University of Technology.

Traffic Flow Webinars: The TrafficLab at Georgia Tech hosts regular Traffic Flow Webinars, some in partnership with the TFT Committee. You can find 25 archived webinars here.

2010 TFT Midyear Meeting: was held July 7-9, 2010 in Annency, France. Papers and presentations are available on the website.

ISTTT19: The 19th International Symposium on Transportation and Traffic Theory was held July 18 - 20, 2011 in Oakland, California. Our committee held a short ancillary summer meeting.

We look forward to your participation and involvement with this committee.

Sincerely,

Robert L. Bertini, Chair
