This year the World Exposition is being held in Hanover, Germany. A number of measures were proposed to handle the expected surplus traffic. This article describes the core system for the traffic control and traffic information centre as it is being implemented in Hanover. The objectives of the traffic control centre include providing reliable prediction of travel times, alternative routing advice, mode choice information, parking guidance as well as reducing disruption caused by incidents. These objectives are tackled by linking various traffic data measurements techniques, a number of ITS traffic control measures and a realtime traffic simulation model. A simulation model called VISUM-online considers all available historical and present traffic data of the Hanover region and uses traffic flow models to predict the current and future situation. The Path Flow Estimator is used to update historical origin-destination-matrices using current traffic counts and assignment modelling. For the covering abstract see ITRD E114174.
