Based on the classical traffic … 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.
