A model and methodology for simulating traffic in conurbation are desc
ribed. The aim of the simulation was the optimization of traffic with
special regard to the air pollution caused. For the determination of t
he solution aimed at intelligent demons monitoring and modifying the m
odel are used. Furthermore knowledge based mobile entities - based on
Knowledge Attributed Petri Nets - for the description of the routing o
f the vehicles are utilized. (C) 1998 IMACS/Elsevier Science B.V.
