Dec 10, 2010 Greenshield's macroscopic stream model Macroscopic stream models represent how the behaviour of one parameter of traffic flow changes with respect to another. Most important among them is the relation between speed and density. The first and most simple relation between them is proposed by Greenshield.mathematical models. Some important models among them will be discussed in this chapter. 3. 2 Greenshields macroscopic stream model Macroscopic stream models represent how the behaviour of one parameter of trac ow changes with respect to another.

Th e microscopic perspective refl ects the behaviour of individual drivers interacting with surrounding vehicles, while the macroscopic per
