Abstract

Starting from microscopic interaction rules we derive kinetic models of Fokker--Planck type for vehicular traffic flow. The derivation is based on taking a suitable asymptotic limit of the corresponding Boltzmann model. As particular cases, the derived models comprise existing models, for example the model by Illner et. al. (2003). New Fokker--Planck models are also given and their differences to existing equations are highlighted. Finally, numerical computations of steady--states are given.
