Greenberg traffic flow model
Webwhere u f is the free-flow speed, and k j is the jam density. . . . In short, Greenshields’ model dominated the field for over 50 years, despite at least three problems. The most fundamental is that Greenshields did not work with freeway data. Yet his result for a single lane of traffic was adopted directly for freeway conditions.
