Uniting What's Next In Intelligent Traffic
As a global leader for intelligent traffic solutions, we connect the dots of a new mobility revolution.

With digitalization and the use of disruptive technologies we enable cities, highway authorities, and (mobility) operators to create a new world of mobility with vehicles that are shared and connected, autonomous tunnel automation, smart tolling and adaptive traffic systems for simulation and prediction. All that allows for a totally new level of traffic management that is truly proactive.

This will transform our cities into places where people can live, work and move more freely with better quality of life, less accidents and with cleaner air. With our expertise and our solutions, we contribute to solving our climate crisis.

Urban mobility must and will change. And we will lead the way
