75 Years of the Fundamental Diagram for Traffic Flow Theory: Greenshields Symposium. Transportation Research Circular, Number E-C149

摘要

The TRB Traffic Flow Theory and Characteristics Committee held a midyear meeting and symposium on the Fundamental Diagram, 75 Years (Greenshields 75 Symposium), July 8- 10, 2008, at the J. Erik Jonsson Conference Center of the National Academy of Sciences in Woods Hole, Massachusetts. The theme of the symposium was 'Celebrating 75 Years of the Fundamental Diagram.' The main topics included historical appreciation of traffic flow theory founders; recent developments and their influence on current practice; the impact of technological developments such as real-time measurements and remote sensing; the current status of traffic flow theory; and the identification of gaps in knowledge and development of research topics to address those areas that need improvement (or lack sufficient experience). Forty-five individuals participated in the symposium and meeting. The idea of the Greenshield's 75 Symposium was originated by Reihnart Kuhne of the German Aerospace Center, who championed the importance of commemorating the seminal contributions of the founders of traffic flow theory.
