Audi's back in the news. This time showing us an Audi concept car which is able to communicate with city traffic lights to find out when they will turn red. It can alert driver how faraway their next red is, and how long it will take to get there - and the speed to drive at so they don't have to stop!

All this of-course requires cities to install smart traffic lights and other manufactures to implement it. Over the course of the six-month test phase, a total of 500 test drivers in 120 cars and three motorcycles covered a total of 1.65 million kilometers (1.03 million miles).

How It Works?

-Information from the traffic light systems is transmitted to the car and shown on the dashboard - or eventually on a heads up display.
-When combined with the motion sensors and speed information from the car, drivers can be told exactly how to avoid stopping at red lights.
-It shows the driver the speed to select in order to reach the next traffic light during a green phase.
-Acoustic signals also warn the driver in advance of red lights.

The system, is linked into a city's electronic traffic light network, and can even take into account lane changes.
Local data from city councils who install smart traffic lights, and motion sensors in the car are used to to predict exactly how long it'll be until the green light goes red.
Audi has been testing the new technology in Ingolstadt and Berlin in Germany, as well as in Verona, Italy, and also set it up in Las Vegas for the CES show.
