Traffic in a metropolitan area can be controlled intelligently only if all participating players are involved and interconnect their infrastructures. The Düsseldorf metropolitan area operates such a comprehensive traffic management system.

GEVAS software was responsible for the whole traffic management center and, among others, the components EventManager and Strategy Management.

The project is a consequent step towards cooperative traffic management: the systems of the City of Düsseldorf and of the Land North Rhine-Westphalia have been connected, forming a fully integrated traffic management system. In case of congestions, joint control strategies are used. Traffic signals and variable message signs can be switched strategically and lead motorists to alternative routes. All information is as well available on the Internet.
