Audi of America announced today an expansion of Traffic Light Information to include Green Light Optimized Speed Advisory (GLOSA), a claimed industry first in vehicle-to-infrastructure (V2I) technologies from the German brand.
Green Light Optimized Speed Advisory can provide speed recommendations to Audi drivers of some 2017 and newer models that can assist drivers in catching the “green wave,” helping to reduce the number of stops at red lights.
The required 4G LTE coverage is not available in all areas. The system also requires compatible traffic infrastructure, which is also not available in all areas and it tracks your location. Connect PRIME services are optional, may require an additional subscription with separate terms. (http://www.audiusa.com/privacy)
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 for the area, and the signal timing plans, are all used to calculate the speed recommendation displayed to the driver.
Survey data from the AAA Foundation for Traffic Safety shows that 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 optimized speed advisories, can help reduce anxiety and improve a driver’s comfort during their time behind the wheel, claims Audi.
“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 U.S.
Today, more than 4,700 intersections support both the “time-to-green” and GLOSA functionalities. Enabled metro areas include Dallas, Denver, Gainesville, Fla.; Houston, Kansas City, Kansas; Las Vegas, Los Angeles, New York City, Orlando, Fla.; Phoenix, Portland, Ore.; San Francisco, and Washington, D.C. and northern Virginia.
Future iterations of V2I technology could include integration with the vehicle’s start/stop function, optimized navigation routing, and other predictive services. All these services are designed to help reduce congestion and enhance mobility on crowded roadways.
