The Prigogine-Herman (PH) model [48] (kinetic model) gives the evolution of the density of particles ρ(t, x, v) as a function of t, x and v, where v is the speed of particles. The model is given by: where C(ρ , ρ) is an interacting term that is, in general, quadratic in ρ and, as such, models the driver behavior in a simple way. From the distribution ρ, we can derive all the useful quantities, such as the average speedv(t, x) = vρ (t, x, v)dv. The integration of the PH model is more time
