Freeway Traffic Flow: Recent Theoretical and Empirical Results — •Martin Treiber and Dirk Helbing — Dresden University of Technology, Institute for Economics and Traffic, D-01062 Dresden

The evaluation of freeway traffic data has revealed various complex patterns of motion including homogeneous and oscillatory congested traffic states (also known as “synchronized flow”) as well as triggered stop-and-go waves and continuous spatial transitions among them (so-called “pinch effect”) [1]. The theoretical model requirements to reproduce these phenomena will be discussed, including solved and unsolved problems of widely scattered flow-density data in sychronized flow. We will also present empirical support for the theoretically predicted phase diagram of traffic states. Apart from this, we will discuss problems and potentials of data processing methods.
