Audi is taking its automated traffic light signal data to Washington, DC. The Traffic Light Information system alerts drivers to lights alee turning red and then gives a countdown to the calorie-free turning greenish. More than than 600 intersections in the District of Columbia support time-to-dark-green communication.

It's one of Audi'south V2I, or vehicle to infrastructure, technologies, significant the motorcar communicates with traffic lights, speed limit signs, construction zones, and electronic toll collection areas, amidst other things.

9 Cities Now Back up TLI

Audi launched Traffic Light Information (TLI) in Las Vegas, Nevada in 2022. In a partnership with Traffic Technology Services, Audi now offers TLI support in nine cities, including parts of Dallas and Houston; Palo Alto and Arcadia, California; Portland, Oregon; and Denver. According to Audi, with Washington at present online, more than than 1,600 intersections across the U.S. support TLI.

Las Vegas made an easy get-go candidate. A large pct of its traffic signals are both controlled and managed from a key location, in this example the public safety building, which houses police, surveillance cameras (both traffic and criminal-investigation), and traffic monitoring. Traffic Engineering Services in Oregon captures the data, analyzes it, and sends countdown information to cars via the Audi Connect Prime telematics service.

When i 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 light is red, TLI displays the time to changes to green in the instrument panel or the head-upwards display. The countdown ends three seconds before green to a) avert drivers trying to jump the calorie-free and b) because TLI isn't currently accurate to fractions of a 2d.

Note again this is a cellular system. The US government has been a big supporter of DSRC, or dedicated short range communications, a 5.9-GHz system that requires a dedicated radio without the latency (filibuster) in the current cellular system. With the advent of 5G, say cellular partisans, latency volition not exist an upshot, and it could exist the preferred schedule for V2I and V2V (vehicle to vehicle) signaling. Traffic Light Information is also ane building block of democratic driving.

Integrated Price Tag Reader: Audi is Big onV2I

Audi this month likewise announced a toll tag reader that is built into rear view mirrors. The Audi Integrated Toll 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 United states of america, Canada and United mexican states. It can be adjusted via the MMI (multi media interface) organisation, or turned off.

It'due south still unclear how much ITM will cost. A standalone toll tag reader costs nearly $25 (if you lose one, otherwise it's free).
