A PHENOMENOLOGICAL MODEL FOR DYNAMIC TRAFFIC FLOW IN NETWORKS

A macroscopic model for dynamic traffic flow is presented. The main goal of the model is the real time simulation of large freeway networks with multiple sources and sinks. First, the authors introduce the model in its discrete formulation and consider some of its properties. It turns out, that their non-hydrodynamical ansatz for the flows results in a very advantageous behavior of the model. Next, the fitting conditions at junctions of a traffic network are discussed. In later sections the authors carry out a continuous approximation of the discrete model in order to derive stationary solutions and to consider the stability of the homogeneous one. It turns out, that for certain conditions unstable traffic flow occurs.
