Many equilibrium models of freeway traffic relationships or 'fundamental diagrams' have
been proposed, but some that appear plausible or convenient turn out unrealistic, and firm …

Ten equilibrium models of congested traffic flow on motorways are evaluated against
oneminute averaged data from several sites in a large data set from Highways England's …

The fundamental diagram, as the graphical representation of the relationships among traffic
flow, speed, and density, has been the foundation of traffic flow theory and transportation …

Speed-flow-density relationships usually depict the interdependence of observable real flow
rates,(mean) speeds and densities. It is shown that" demanded" or" desired" speed-flow …

The speed–flow and flow–density relations at the motorway network of the greater
Copenhagen region are explored based on a large data sample consisting of a total of 5.3 …

As the graphical and mathematical representation of relationships among traffic flow, speed,
and density, the fundamental diagram has been the foundation of traffic flow theory and …

The speed-density or flow-density relationship has been considered as the foundation of
traffic flow theory. Existing single-regime models calibrated by the least square method …

This year the Transportation Research Board celebrates the 75th anniversary of
Greenshields' pioneering work on traffic flow, and TRL also celebrates its 75th year since …

There is a need for a better understanding of freeway operations under congested
conditions. Not only are major freeways in many cities congested several hours a day, but …
