ONLINE TRAFFIC SIMULATION WITH CELLULAR AUTOMATA

The development of dynamic traffic information systems is one of the most important challenges in the field of Intelligent Transportation Systems ITS. A promising way is to couple simulations of the actual traffic state together with online counting data stemming from detection devices, e.g. induction loops. The aim is to generate a one-to-one image of the individual on-road car motion in the computer and to derive the relevant information from the simulation results. In addition, the simulation serves as an “interpolation” for regions which are not adequately covered by measurements. In this contribution the method of online simulations is discussed and some results are reported.
