Audi will expand its Traffic Light Information to include Green Light Optimised Speed Advisory (GLOSA), another industry first in vehicle-to-infrastructure (V2I) technologies from the brand. GLOSA can provide speed recommendations to Audi drivers of select 2017 and newer models that can assist drivers in catching the ‘green wave,’ helping to reduce the number of stops at red lights.
GLOSA uses traffic signal information and the current position of a vehicle to display a speed recommendation intended to allow drivers to pass traffic lights during a green interval, in order to help reduce the number of stops at red lights. The distance to stop, the speed limit profile for the area, and the signal timing plans, are all used to calculate the speed recommendation displayed to the driver.
According to survey data from the AAA Foundation for Traffic Safety, the average American driver spends nearly 300 hours a year behind the wheel, the equivalent to seven 40-hour weeks at the office. Providing drivers with additional information, such as green light optimised speed advisories, can help reduce anxiety and improve a driver’s comfort during their time behind the wheel.
“Audi is committed to moving America in many ways, including through the development of industry-leading connectivity and mobility solutions,” said Mark Del Rosso, president, Audi of America. “Not only do vehicle-to-infrastructure technologies like GLOSA benefit drivers today, they’re also the critical steps needed as we continue toward an automated future.”
In 2016, Audi, in collaboration with Traffic Technology Services (TTS), launched Traffic Light Information, an Audi connect PRIME feature that enables the car to communicate with the infrastructure in certain cities and metropolitan areas across the US. Today, more than 4,700 intersections support both the ‘time-to-green’ and GLOSA functionalities.
“VDOT’s collaboration with Audi, TTS, and other innovative companies leverages the Commonwealth’s data and vehicle-to-infrastructure communications, preparing us for more connected and automated vehicles on our roadways,” said Virginia Secretary of Transportation Shannon Valentine. “We are committed to improving safety, reducing congestion and exploring opportunities to partner with the private sector.”
