Audi is taking its automatic traffic light bespeak data to Washington, DC. The Traffic Light Information system alerts drivers to lights ahead turning red and then gives a countdown to the light turning green. More than 600 intersections in the District of Columbia back up time-to-greenish communication.

It's one of Audi'due south V2I, or vehicle to infrastructure, technologies, meaning the car communicates with traffic lights, speed limit signs, construction zones, and electronic cost collection areas, among other things.

9 Cities At present Support TLI

Audi launched Traffic Light Data (TLI) in Las Vegas, Nevada in 2016. In a partnership with Traffic Technology Services, Audi now offers TLI back up in nine cities, including parts of Dallas and Houston; Palo Alto and Arcadia, California; Portland, Oregon; and Denver. According to Audi, with Washington now online, more than one,600 intersections across the U.S. back up TLI.

Las Vegas made an easy start candidate. A large percentage of its traffic signals are both controlled and managed from a central location, in this case the public safe edifice, which houses constabulary, surveillance cameras (both traffic and criminal-investigation), and traffic monitoring. Traffic Technology Services in Oregon captures the data, analyzes information technology, and sends countdown data to cars via the Audi Connect Prime telematics service.

When one of these select Audi models approaches a connected traffic light, the machine with Traffic Light Information receives, via 4G LTE cellular (currently), real-time signal information from the traffic management system. When the lite is carmine, TLI displays the fourth dimension to changes to green in the instrument panel or the head-upwardly brandish. The countdown ends three seconds before green to a) avoid drivers trying to jump the light and b) because TLI isn't currently accurate to fractions of a second.

Annotation again this is a cellular system. The U.s. government has been a big supporter of DSRC, or defended brusque range communications, a five.9-GHz organization that requires a dedicated radio without the latency (delay) in the electric current cellular system. With the advent of 5G, say cellular partisans, latency will non exist an effect, and it could be the preferred schedule for V2I and V2V (vehicle to vehicle) signaling. Traffic Light Information is also 1 building block of autonomous driving.

Integrated Toll Tag Reader: Audi is Big onV2I

Audi this month also announced a price tag reader that is built into rear view mirrors. The Audi Integrated Price Module is a partnership with Gentex, the maker of specialized rear view mirrors. According to Audi, it works with all cost reader systems in the US, Canada and Mexico. It can be adjusted via the MMI (multi media interface) system, or turned off.

It's even so unclear how much ITM volition cost. A standalone toll tag reader costs well-nigh $25 (if you lot lose one, otherwise it's free).
