The development teams at Audi see the task in its entirety, and examine the complete road traffic system. Their travolution project is a concept for a dialogue between cars and traffic signals. It reduces the amount of time spent at a standstill or accelerating, and in this way cuts the vehicles' fuel consumption.
The traffic signals transmit data that are processed into graphic form and shown on the car's driver information display screen. The graphics tell the driver for instance what speed to adopt so that the next traffic light changes to green before the car reaches it. The travolution system also makes it possible to pay online when refueling or parking the car. The car itself communicates with the stationary equipment at the filling station or parking garage. When the driver confirms the charge via the Multi Media Interface MMI, it is automatically debited from the customer's account or credit card
