Audi: cars talk to traffic lights in Dusseldorf thanks to V2I


Audi announced that it has extended its service Traffic Light Information also within the city of Dusseldorf. After the debut on the Old Continent in Ingolstadt, the city that stands on the banks of the Rhine river will be the second in Europe where Audi has decided to implement the technology that allows you to receive information on the operation of traffic lights in your cars.

Starting from the end of January, all those who drive an Audi compatible with this service will be able to receive the on board directly information of 150 traffic lights in the city. This way you can modulate the speed to always be able to “get green” thus optimizing travel times and fuel consumption.

The integration of this infrastructure within the German city will continue over the next few months. By the summer, around 450 of the city’s 600 crossroads will be connected.

Audi Traffic Light Information is an example of V2I technology, that is Vehicle-to-Infrastructure thanks to which Infrastructure and vehicle communicate with each other exchanging information for improve efficiency, practicality and road safety.

The Audi Traffic Light Information system offers drivers two main functions: Green Light Optimized Speed ‚Äč‚ÄčAdvisory (GLOSA) is Time-to-Green.

The first calculate the ideal speed to take the green and not have to stop at the traffic lights. This feature may also suggest gradually lowering the speed about 250 meters before the traffic light, so that the driver and the cars behind reach the intersection when the lights turn green.

If it is inevitable to stop at the traffic lights, a countdown shows the seconds left until the green light returns (Time-to-Green). In this way, drivers will be able to relax as they know exactly how much they will miss when starting again.

Audi Traffic Light Information was unveiled for the first time in 2016 in Las Vegas. Today, this V2I service is available at over 10,000 crossings in North America, including around 2,000 in Manhattan / New York City and over 1,600 in the capital of the United States.

This feature is available on the Audi e-tron models (here our road test), A4, A6, A7, A8, Q3, Q7 and Q8 which have been produced since mid-July 2019.
