Abstract English We use linear stability analysis to develop a theory which can predict traffic flow<br> behavior for the unstable flow regime of concentrations. The equilibrium solution of the kinetic<br> equation of Prigogine and Herman is used to obtain closed form models of traffic flow, when<br> viewed under asymptotic (Chapman-Enskog) limit expansions, since it can produce reasonable<br> flows for the whole range of concentrations. A zeroth-order Chapman-Enskog model is found for<br> this range. The Godunov scheme is used to solve this model under a traffic release type of initial<br> condition.
