Audi Car-to-X Communication

Normally, I wouldn’t post about a product or service on Travelivery Las Vegas, unless it had to do with Las Vegas. But, because Audi has tested or is testing it’s new Car-to-X Communication technology in Las Vegas, I felt compelled to talk about it.

Make sure you also check out the video below, which shows the Audi doing its tests on the Las Vegas Strip.

Car-to-X Communication
Car-to-x communication, an important aspect of Audi connect, opens up numerous new possibilities for making driving safer, more relaxed and more economical.

Cars that are networked together can warn one another about hazards such as slippery roads or cross-traffic at intersections, for example. Car-to-x communication is also extremely well suited for the dissemination of traffic information data. Automotive WLAN communication, in particular, can generate very precise and exact data.

Online traffic light information
Among the new car-to-x applications at Audi is the service Online traffic light information. It networks the car with the central traffic control computer that controls the traffic lights in the city. Targeted information appears in the display of the driver information system. It shows the driver the speed to select in order to reach the next traffic light during a green phase. The time remaining is displayed while waiting for the light to turn green.

Audi developed and tested the principle of the new Online traffic light information service as part of the Travolution project in Ingolstadt and the nation-wide field trial simTD (Safe and Intelligent Mobility Test Field Germany). It benefits not just the drivers by making traffic more fluid, less stressful and safer, but also the cities and the environment in which it is used. According to Audi’s calculations, CO2 emissions can be reduced by up to 15 percent. If deployed throughout Germany, this would correspond to a savings of roughly 900 million liters (237,754,847.12 US gallons) of fuel.

Audi is currently gathering additional experience in multiple field trials. In the northern Italian city of Verona, some 60 traffic lights covering nearly the entire city center are part of the trial. A field trial in Berlin involves a total of 1,000 traffic lights and 25 Audi cars driven by customers. No other carmaker is active on such a large scale. The principle is currently being demonstrated with 50 traffic lights in the American city of Las Vegas, Nevada.

The results show that the technology for the Online traffic light information system has reached market maturity. Provided that enough cities make their data available, there is nothing standing in the way of a broad rollout. A market launch is currently the subject of intense analysis in the United States. – Learn More
