WebDec 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 … WebIn the fluid-flow analogy, the traffic stream is treated as a one-dimensional compressible fluid. This leads to two basic assumptions: (1) Traffic flow is conserved, and this leads to the conservation or continuity equation. (2) A one-to-one relationship exits between speed and density or between flow and density.
