For an experienced human driver, the "operational" driving tasks seem to be easy: After all, one usually has no problem to accelerate or brake in order to reach a desired speed, or keeping sufficient space to avoid crashes. The same applies when deciding if it is safe to enter a priority road, to overtake, or to pass a "yellow" traffic light that will be "red" in the next few seconds. When attempting to cast this driving behaviour into equations of a mathematical model, however, one feels more like a driving beginner: It is all but easy to find models that reproduce the human driving behaviour! In this talk, I will discuss "car-following models" for the accelerations, and "decision models" for discrete-choice situations such as lane changing or entering a priority road. The models can be parametrized to represent driving behaviour such as timid/aggressive, experienced/unexperienced, or fast vs. relaxed. One model has been implemented into a semi-automatic car, and the author has been driven with it on public freeways. I will report about this experience. Fially, by means of simulations, I will show how external measures (such as speed limits), and the drivers themselves influence the probability of traffic breakdown and the development of stop-and-go traffic.
Martin Treiber [Dr. rer. nat., 1996, University of Bayreuth, Germany] is at the Departement of Transport and Traffic Sciences, Dresden University of Technology, Germany. He teaches traffic modelling & simulation, econometrics, and statistics. His research interests include vehicular traffic dynamics and modelling, traffic data analysis & state estimation, and driver ass istance systems. This includes several public and commercial projects. He developed a ra nge of simple yet realistic traffic models and runs the popular web site www.traffic-simulation.de . He has over 60 peer-reviewed publications and currently is writing a textbo ok on traffic modeling and simulation.
