SOME RECENT DEVELOPMENTS IN CONTINUUM VEHICULAR TRAFFIC FLOW THEORY

A qualitative overview of some recent developments in continuum vehicular traffic flow theory is presented in this paper. An assessment of recent research efforts is first provided on the fundamental diagram that attempts to establish linkages between static flow density-speed relationships and dynamic traffic flow phenomena. A discussion then follows of the emerging continuum models that treat multiple vehicle classes and lane types as well as the non-equilibrium models that eliminate certain undesirable properties in the high-order continuum models and capture more realistically the instabilities in traffic transitions. The paper also presents some limited field observations associated with the discussed theories. A brief discussion is presented on the challenge to improve the existing continuum traffic flow model.
