Audi had announced earlier that it was working on a technology that would allow its cars to communicate with traffic lights so that drivers will know when the lights will turn green from red. The German luxury carmaker is now ready to roll out the technology in the real world starting in Las Vegas.
Drivers of Audi cars will not have to wait and wonder when the traffic light will turn from red to green. Audi will be the first automobile brand to connect the car to the city infrastructure, which is an important step towards autonomous driving.
The company has launched its new autonomous technology in Las Vegas and starting immediately, the Audi A4 and Q7 models can display traffic-light phases directly in the car.
Traffic Light Information is a technology which optimises traffic flow, saves time and reduces environmental impact.
Andreas Reich, head of Electronics Pre-Development at Audi AG said that for the first time their cars will interact with traffic infrastructure in real time and drivers can adapt their behaviour to the situation and move through city traffic in a relaxed and controlled way.
He further added that they increase energy efficiency when we connect their Audi models to smart cities and further V2I services will follow, making the car into an interactive mobile device and they see autonomous driving as the end of this development.
Municipal traffic management centres in the USA will communicate the traffic-light data to Audi's project partner Traffic Light Information (TTS).
The first function of the Traffic Light Information V2I component is called Time-to-Green. In the Audi heads-up display or the virtual cockpit, drivers see if they will reach the next light on green while traveling within a specified speed limit. Otherwise, a countdown is provided of the time remaining until the next green phase.
Audi is planning to introduce the technology in Europe. Cities like Berlin, Ingolstadt, Garmisch-Partenkirchen and Verona pilot projects have already been extensive, while in Berlin alone, nearly 700 traffic lights in the inner city have been connected to the service.
Audi is working to harmonise the data that have been prepared and after that is done, they will provide Traffic Light Information in Europe too.
