Abstract
Since the beginning of this millennium, many models of multiclass continuum traffic flow have been proposed. A set of qualitative requirements is presented for this type of model, including nonincreasing density–speed relationships and anisotropy. The requirements are cast into a framework that applies a generalized model of deterministic multiclass kinematic wave traffic flow. A step-by-step plan is developed to apply the framework to models that fit into the generalized model. The plan could be developed only with the Lagrangian formulation of the generic model but could also be applied to models in the traditional Eulerian formulation. It was concluded that only a few models known from the literature satisfied all requirements unconditionally. The step-by-step plan can furthermore be applied in the development of new models, the adaptation of existing models, and the calibration of model parameters.
