Audi tech counts down red lights today, reduces traffic tomorrow

Audi announced today that in Washington D.C. and Las Vegas, select Audi Q7 and A4 models will be able to take advantage of new vehicle-to-infrastructure technology. The technology was developed with Traffic Technology Services and will allow drivers to see how long it will take for a traffic light to change to green. Compatible traffic lights will send information through servers operated by Traffic Technology Services to properly equipped Audis. This may not sound like an earth-shattering feature at first, unless you're a stoplight drag racer – if Audi has its way, it may shut off the timer at about 10 seconds to prevent such a thing – but the technology opens up the door to much more useful features down the road. Audi's general manager for connected vehicles, Pom Malhotra, suggested that the information could be used with "vehicle navigation, engine start/stop functionality and can even be used to help improve traffic flow." More specifically, navigation could account for traffic light timing to divert drivers to a more efficient and faster route. It could even suggest acceleration and speed to hit signals when they're green, minimizing stops and starts. Then, for engine start and stop features, the car could selectively shut off at long stops but remain on when approaching a light that's about to turn green. Traffic lights could also start adjusting patterns based on how many cars are approaching a light or are stuck at a light, alleviating slow-moving traffic. Vehicle-to-infrastructure communication could lead to roads that waste less time and less energy. While Audi didn't elaborate on this topic, vehicle-to-infrastructure technology could also be useful for future autonomous car technology. For instance, the car wouldn't necessarily have to "see" the actual traffic light. Instead, it could rely on a separate signal from the smart traffic light to know it has to stop or go. Going a step further, the technology could be used to manage traffic so precisely that traffic signals are no longer needed, as some other groups have investigated. And, of course, the aforementioned benefits in navigation technology would help autonomous vehicles make smarter route decisions as well. The feature is currently only available on Audi Q7, A4 and A4 allroads built after June 1, 2016. It's also only available as part of Audi connect PRIME, a subscription-based service that provides various infotainment and streaming features for your Audi. While D.C.

Stanford goes from Pikes Peak to Thunderhill with autonomous Audi TTS

In the years since Stanford University engineers successfully programmed an Audi TTS to autonomously ascend Pikes Peak, the technology behind driverless cars has progressed leaps and bounds. Back then the Audi needed 27 minutes to make it up the 12.42-mile course – about 10 minutes slower than a human driver. These days, further improvements allow the vehicle to lap a track faster than a human. The researchers recently took their autonomous TTS named Shelley to the undulating Thunderhill Raceway Park, and let it go on track without anyone inside. The Audi reportedly hit over 120 miles per hour, and according to The Telegraph, the circuit's CEO, who's also an amateur racing driver, took some laps as well and was 0.4 seconds slower than the computer. To make these massive technological advancements, the Stanford engineers have been studying how racers handle a car. They also hooked up drivers' brains to electrodes and found the mind wasn't doing as much cognitively as expected. It instead operated largely on muscle memory. "So by looking at race car drivers we are actually looking at the same mathematical problem that we use for safety on the highways. We've got the point of being fairly comparable to an expert driver in terms of our ability to drive around the track," Professor Chris Gerdes, director of Stanford's Revs Program, said to The Telegraph. With progress coming so rapidly, it seems possible for autonomous racecars to best even elite drivers at some point in the near future. Related Video:
