Back in late 2016, Audi became the first automaker in the U.S. market to enable vehicle-to-infrastructure (V2I) communications in some of its vehicles. Initially only available in Las Vegas, Audi is now adding four new cities to the lineup and deploying a new feature designed called Green Light Optimization Speed Advisory (GLOSA) to help drivers hit more green lights…
The recommended speed is calculated based on the signal timing data, distance to stop and local speed limit profile. If the driver is going over the posted speed limit, no GLOSA advisory will be displayed.
This can help improve overall traffic flow and reduce fuel consumption by reducing the repeated acceleration and braking of going from one red to another.
