The basic features of the Boltzmann-like model for traffic flow, due to Prigogine and coworkers, are reviewed. Comments are presented concerning a recent controversy on the collision integral. For a set of "ideal experiments" results are obtained that are physically unsatisfactory. This shown to be due to the form of the relaxation term appearing in Prigogine's vehicular Boltzmann equation. An alternative model is proposed for dilute traffic conditions. The main properties of the new model are discussed.
