Traffic Flow Theory and Characteristics Committee (AHB45)
2014 Summer Meeting - August 11-13, 2014 - Portland, Oregon USA
Symposium Celebrating 50 Years of Traffic Flow Theory

Symposium Program | Symposium Photos | Proceedings: Transportation Research Circular E-197

The Transportation Research Board (TRB) Committee on Traffic Flow Theory and Characteristics Symposium Celebrating 50 Years of Traffic Flow Theory and Midyear Meeting was held in Portland, Oregon, USA, August 11-13, 2014. Top papers are published in special issues of Transportmetrica B and the Journal of Intelligent Transportation Systems, and all papers will be published in a special issue of the Transportation Research Circular series

The predecessor committee focusing on traffic flow theory was organized 50 years ago, and this is an appropriate time to recognize the past accomplishments in the field, reflect on the present state of our research community and identify key future directions. This symposium builds on past successful symposia beginning with the Greenshields Symposium in Woods Hole, MA in 2008, the Does Traffic Data Support Traffic Models Symposium in Annecy, France in 2010 and the Symposium on Advancements in Traffic Flow Theory and Highway Capacity and Quality of Service in Fort Lauderdale, FL in 2012.
