HYDRODYNAMIC APPROACHES

THE APPLICATION IS DISCUSSED OF FLUID FLOW PRINCIPLES TO THE TRAFFIC STREAM. REGARDING TRAFFIC AS A HYDRODYNAMIC FLOW BASES THE ANALYSES ON A PARTIAL DIFFERENTIAL EQUATION EXPRESSING THE CONSERVATION OF MATTER AND AN ASSUMED EMPIRICAL RELATION BETWEEN THE FLOW AND CONCENTRATION. THE SOLUTION OF THE EQUATION INDICATES THAT DISCONTINUITIES IN THE TRAFFIC FLOW ARE PROPAGATED IN A MANNER SIMILAR TO SHOCK WAVES IN THE THEORY OF COMPRESSIBLE FLUIDS. AN APPROACH IS PRESENTED TO THE BEHAVIOR OF SHOCK WAVES IN THE TRAFFIC STREAM. THE LIGHTHILL-WHITHAM AND RICHARDS THEORIES ARE COMPARED.
