Abstract

We study a traffic flow model with inhomogeneous road conditions such as obstacles. The model is a system of nonlinear hyperbolic equations with both relaxation and sources. The flux and the source terms depend on the space variable. Waves for such a system propagate in a more complicated way than those do for models with homogeneous road conditions. The L-1 well-posedness theory for the model is established. In particular, we derive the continuous dependence of the solution on its initial data in L, topology. Moreover, the L-1-convergence to the unique zero relaxation limit is proved. Finally, the asymptotic states of a general solution whose initial data tend to constant states as \x\ --> +infinity are constructed.
