Audi travolution promotes eco-friendly driving

Exploring new ideas for urban mobility -- Audi improves efficiency and safety in road traffic with their new travolution technology. If the car is stopped at a red traffic light, this transmits information via the car's computer on how long the driver will have to wait before it switches to green again. If on the other hand the car approaches a traffic light that is about to switch to yellow or red, the driver is warned by a visual or acoustic signal, or by a brief interruption to the flow of power from the engine.
