Audi, like all manufacturers, churns out cars that add to the congestion on roads around the world. However, this particular German manufacturer has also been busy investing time and money on what it is calling the "Travolution” system - a concept designed to improve traffic infrastructure.

Currently, the "Travolution” system is being used at 46 traffic lights in the municipal area of Ingolstadt. The Travolution software optimizes the entire network of traffic lights, significantly reducing the duration of stopping times for cars – and thus idling, braking and downshifting with predictable fuel efficiency benefits.

An additional part of the project is called “The informed driver.” For this, three traffic lights have been equipped with communications modules that send the time for the next green-light phase to the car’s on-board computer.

As part of their commitment to the Travolution system, Audi has made an Audi A5 and an A6 Avant available as test vehicles for the project. The Travolution system communicates with the drivers of these cars via the Audi MMI infotainment system, providing information such as what speed they should travel at in order to drive through an intersection without having to stop.

“Travolution blazes the trail for innovative traffic management of a magnitude unique in Germany. The result is a functioning prototype for the traffic control of the future,” said Dr. Werner Widuckel, Audi Board Member for Human Resources.

Aside from Audi, participants include the city of Ingolstadt’s Office for Traffic Management and Geoinformation, the Professorial Chair for Traffic Engineering at the Technical University of Munich, and GEVAS software GmbH. To-date the venture partners have invested around €1.2 million in the Travolution system.

Additional follow-on projects based on Travolution are to be initiated by the venture partners. The field for research in Ingolstadt is to be expanded by another 20 cars and 50 traffic light installations. In addition, up-to-the-minute traffic information for the city will keep drivers better informed.
