Simulation of traffic in large road networks

The modeling and simulation of traffic flow nowadays is one of the most pro mising strategies to generate traffic information. The efficiency of even m icroscopic simulation models is high enough to allow for reproducing the fl ow of whole networks in multiple real time. The derails of the car motion h ave to be defined very carefully in order to yield the correct traffic stat es in various situations, e.g., bottlenecks, intersections and on- and off- ramps. In this paper the current status of the work in this field is report ed acid the application to the road network of the downtown area of Duisbur g is discussed. (C) 2001 Elsevier Science B.V.
