Two New Transportation Research Circulars


The Transportation Research Board (TRB) Committee on Traffic Flow Theory and Characteristics (TFTC)found several ways to commemorate the 50th Anniversary of the establishment of the TFTC in 1963. The first was a workshop held January 12, 2014 at the TRB 93rd Annual Meeting that focused on traffic and transportation simulation. The workshop provided a means to explore the history, current status, and future of traffic simulation. The results are documented in TRB’s Transportation Research Circular E-C 195: Traffic and Transportation Simulation - Looking Back and Looking Ahead: Celebrating 50 Years of Traffic Flow Theory.  The second was Standing Committee on Traffic Flow Theory and Characteristics Summer Meeting and Symposium, August 11–13, 2014 in Portland, Oregon. Presentations covered fundamental diagrams, traffic flow models, traffic control, freeway traffic analysis, calibration, empirical observations of traffic analysis, networkwide modeling and control, and other paper and poster presentations. Presenters reflect on the fifty years of traffic flow theory and include an analysis of pedestrian flows and the incorporation of autonomous vehicles into traffic theory. The results are documented in TRB E-Circular 197: Celebrating 50 Years of Traffic Flow Theory. Thanks to all of the volunteers who helped organize these fantastic events!
