Audi – giving us more green lights

27th February 2019 | Leave a comment

This week Audi launched new technology designed to reduce stress and congestion; it is another step towards a future of autonomous cars.

The technology, Green Light Optimized Speed Advisory (GLOSA) communicates with city infrastructure (V2I) to let drivers know what speed they should travel at in order to hit all the green lights. It combines a series of factors to make the time estimate, including traffic signal information, the position of the car, the distance to the lights and the speed limit. Created in response to industry demand to make the in-car experience efficient both in time and cost. The AAA Foundation for Traffic Safety data shows that drivers in American cities spend about 300 hours a year behind the wheel, so every effort is being made to reduce driver stress, cost of fuel and time.

Audi is not the only active company in the Vehicle to Infrastructure (V2I) space. V2I patent filings have been increasing since the 2000s, peaking in 2010. There are around 100 to 150 new filings per year in this area.

What is interesting is despite the innovations from Audi, one of the leading German OEMs, we see that Asian players dominate the top 10 owners with Sumitomo Electronic winning the race.

Looking in more detail at V2I patent filings in the last two years, we can see a range of applications including parking, traffic and navigation and safety. In the safety space, the infrastructure supports detection of and communication between vehicles, pedestrians and infrastructure to avert accidents. “Green channels”, where emergency vehicles communicate with other vehicles and traffic lights, to allow quick and safe street navigation for emergency vehicles are also an interesting application for V2I.

The increasing application of V2I data and technology shows that the future is bright, “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” said Mark Del Rosso, president, Audi of America.

Future gazing allows an appreciation for how the V2I technology could include integration with the vehicle’s start/stop function or optimised navigation routing. All of these services are designed to help reduce congestion and enhance mobility on crowded roadways.
