Simulation of traffic in large road networks

摘要

The modeling and simulation of traffic flow nowadays is one of the most promising strategies to generate traffic information. The efficiency of even microscopic simulation models is high enough to allow for reproducing the flow of whole networks in multiple real time. The details of the car motion have to be defined very carefully in order to yield the correct traffic states 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 reported and the application to the road network of the downtown area of Duisburg is discussed.
