Green Light for Audi’s New Traffic Light Assist Technology
This fall, Audi will begin offering a new traffic light technology in three of its models so that it’s possible to rarely stop at a red light. The technology is part of Audi Connect Prime services infotainment package subscription for the 2017 Audi A4, A4 Allroad, and Q7 SUV. The technology, called V21, enables a car to communicate with an urban area’s traffic light infrastructure. At first, the technology will be rolled out in a few select cities and metro areas in the United States.
The new technology relies on local data that relays patterns and timing through Wi-Fi. A driver is shown the right speed to follow with a traffic light image that features lit up red, amber, and green icons to adjust driving in order to make a green light. If a light is missed, the system counts time until the next green light and works with the start/stop function to make sure the engine is on before a light turns green. Audi reports that in large-scale tests in Germany the technology can help reduce CO2 emissions by as much as 15%.
In the United States, Audi is working with Traffic Technology Services, Inc., based in Portland, OR, to access data and route the information through an LTE data connection in the vehicle. Audi officials suggest that in the future, this new technology could be integrated into the vehicle’s navigation and start/stop systems to lead to better fuel efficiency and even shorter commuting times. Field tests have been conducted in a number of cities, including Berlin, Verona, and Las Vegas.
