A cellular automaton traffic flow model for online simulation of traffic

摘要

Spatially and temporally dissolved information about traffic states in road networks is a basic requirement for the application of intelligent transport systems (ITS). We present a concept for online simulations of traffic in road networks f real-time traffic data stemming from inductive loops serve as input for high-speed microsimulations using a cellular automaton traffic flow model. The quality of the reproduced traffic states is investigated with regard to vehicular densities and link travel times. As an example for dynamic traffic management we studied different strategies for individual en-route guidance systems and their efficiencies. For all investigations the road network of Duisburg served as the study area.
