2125 Audi is ready to add a little oil to the wheels of the daily grind with advanced traffic light recognition technology which could make driving through towns and cities far more fluid.

Audi Online traffic light information harnesses the power of in-car internet in a new way via Audi connect to establish a link between the car and the traffic light network via the central traffic computer in each town or city. It quickly assimilates the automated traffic light change sequences in the vicinity, and on the approach to a set of lights the driver information system (DIS) in the central instrument cluster shows the driver the speed to select in order to pass through the light during a green phase. It also displays a visual aid using red, amber or green icons.

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 via a timer on the DIS. The system also interacts with the car’s start-stop function to ensure the EngiNe is switched on five seconds before the green phase.

Audi calculates that Online traffic light interaction has the potential to reduce CO2 emissions by up to 15 per cent, and could save approximately 900 million litres of fuel if it were to be deployed throughout Germany.

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

    Connected offers free I2V connectivity
    A new system could reduce the cost of implementing I2V communications across a city to less than that for a single intersection, as Colin Sowman hears. It may seem too good to be true but US company Connected Signals is offering city authorities the equipment to provide infrastructure to vehicle (I2V) communications for free. The system enables drivers to receive information about the timing of signals they are approaching via the EnLighten smartphone app (or connected in-vehicle display).
