The context of this thesis is particle systems. We deal with different physical systems, described continuously, whose dynamics are modeled by partial differential equations. These equations follow the evolution in time of macroscopic or microscopic quantities, according to scale description. In the first part, we consider a kinetic model for...

In [7], Berthelin, Degond, Delitala and Rascle introduced a traffic flow model describing the formation and the dynamics of traffic jams. This model consists of a Pressureless Gas Dynamics system under a maximal constraint on the density and is derived through a singular limit of the Aw-Rascle model. In the present paper we propose an...
