Audi has unveiled a Traffic Light Information system, which connects the car to the city infrastructure and promises to reduce emissions and make driving ‘more relaxed’.

The Traffic Light Information system works by displaying traffic light phases in the car.

Drivers will be able to see what colour the next set of traffic lights will be when they arrive there. If the lights are red, a countdown is provided of the time remaining until the next green phase, therefore allowing the driver to slow down enough to prevent needing to come to a stop.

Municipal traffic management centres will communicate the traffic-light data via Audi’s project partner Traffic Technology Service sTTS to the vehicle’s on-board computer using a fast Internet connection.

So far, the system has been introduced on US spec A4 and Q7 models, and currently only works in Las Vegas.

However, further US cities are due to follow, and Audi then plan to introduce the system into Europe.

In the future, the technology will also benefit vehicles from other brands.

Head of electronics pre-development at Audi AG Andreas Reich said: “For the first time, our cars are exchanging data with traffic infrastructure in real time. Drivers can adapt their behaviour to the situation and move through city traffic in a much more relaxed and controlled way.

“We increase energy efficiency when we connect our Audi models to smart cities. Further V2I (vehicle to infrastructure) services will follow, making the car into an interactive mobile device. We see autonomous driving as the end of this development.”
