Revolutionary new tech for Audi could make sitting at red lights a thing of the past

Audi has revealed a new traffic light recognition system that has the potential to allow drivers to drive through city streets without the interruption of hitting red lights. A fully developed Audi A6 prototype fitted with the technology was showcased at the Consumer Electronics Show (CES) in Las Vegas last year.

The system works by harnessing the in-car Internet via Audi connect, which then creates a link between it and the local traffic light network. The automated traffic light sequence of the area is processed and relayed back to the driver, showing the speed necessary to pass through an upcoming green light.

If the driver is already waiting at a red light, Audi connect will calculate and count down the time remaining until the next green light is scheduled to appear. The system is also linked up to the car’s Start-Stop function and restarts the engine five seconds before the green light appears.

As well as a providing a more relaxed drive, the technology could also help reduce emissions by up to 15 per cent, while helping save fuel in the process. Audi has calculated if the system was to be rolled-out across Germany, almost 900 million litres of fuel could be saved per year.

The fully functional system is production ready and could be fitted to every Audi model in the range subject to the necessary government legislation.
