A Framework to Assess Multi-class Continuum Traffic Flow Models

Abstract

Since the beginning of this millennium many multi-class continuum traffic flow models have been proposed. We present a set of qualitative requirements for this type of models, including nonincreasing density-speed relations and anisotropy. The requirements are cast into a framework that applies a generalised deterministic multi-class kinematic wave traffic flow model. A step-by-step plan is developed to apply the framework to models that fit into the generalised model. The plan could only be developed using the Lagrangian formulation of the generic model, but it can also be applied to models in the traditional Eulerian formulation. We conclude that only few models
known from literature satisfy all requirements unconditionally. The step-by-step plan can further more be applied in the development of new models, the adaptation of existing models and the calibration of model parameters.
