Audi of America is introducing Green Light Optimised Speed Advisory (GLOSA) system to some of its vehicles to help drivers travel at the right speed to minimise the number of stops needed 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.
“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.”
The announcement follows the 2016 introduction of Audi’s Traffic Light Information, a 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 in areas such as Dallas, Denver, Houston, Kansas City, Las Vegas, Los Angeles, New York City, Orlando, Phoenix, Portland, San Francisco, and Washington, DC.
Audi says future iterations of its V2I technology could include integration with the vehicle’s start/stop function and optimised navigation routing.
