In 2016, Audi collaborated with Traffic Technology Services and launched Traffic Light Information or TLI. TLI is an Audi connect PRIME feature available on select 2017 and newer models that allows the vehicle to connect with Traffic Technology Services in certain cities and metropolitan areas across the U.S. 

 

Recently, Audi announced that Green Light Optimized Speed Advisory, or GLOSA, will be included as an expansion of their Traffic Light Information. GLOSA provides speed recommendations to Audi drivers of select 2017 and newer models to help reduce the number of stops at red lights.

 

Using traffic signal information and the current position of the vehicle, GLOSA displays a speed recommendation to allow drivers to pass traffic lights during a green interval. To calculate the speed recommendation, GLOSA uses information such as the distance to stop, the speed limit profile for the area, and the signal timing plans.

 

While GLOSA works hard to keep drivers from being stuck at too many red lights, it’s not a guarantee that drivers will always catch a green wave.Thats where TLI comes in. When a select Audi model approaches a connected traffic light, real-time signal information is received via the traffic management system that monitors traffic lights using the on-board 4G LTE data connection. If the light is red, the TLI will display a “time-to-greencountdown until the signal changes to green in the instrument cluster in front of the driver or in the head-up display if its equipped. As of now, more than 4,700 intersections support GLOSA and “time-go-greenfunctionalities.

 

“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 of Audi of America. Not only do vehicle-to-infrastructure technologies like GLOSA benefit drivers today, theyre also the critical steps needed as we continue toward an automated future.

 

Future vehicle-to-infrastructure technology could include other predictive services such as integration with the vehicles start/stop function and optimized navigation routing to help enhance mobility on crowded roadways.
