So if we can recall back in 2016 Audi became the first automaker in the U.S. market to enable vehicle-to-infrastructure (V2I) in some of it vehicles. Initially available only in las vegas Audi is now adding four new cities to the lineup and also on top of that it introducing called Green Light Optimization Speed Advisory (GLOSA) to help drivers hit more green lights.
Vehicles with this tech would be able to communicate with local traffic control systems through the Audi servers over 4G LTE connections to get data about signal timing. The initial traffic light information (TLI) application provided alerts to drivers about red lights they were approaching and countdown timer for the switch to green. The alerts are provided in the instrument cluster and heads-up display if the car has one.
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. If groups of vehicles can flow directly from one green to the next without slowing or accelerating, there is also a reduced likelihood of collisions from sudden braking events. With the addition of Denver, Colorado, White Plains, NY, Gainesville, Florida and Orlando, Florida there will now be 13 cities in the U.S. that work with the Audi V2I system.
Expansion of the connected intersections in the nine existing cities also means the total number of supported intersections doubles to more than 4,700 this year. Eventually, Audi plans to integrate the TLI into other systems like automatic stop-start and automated driving to improve the functionality and effectiveness of those system.
But to use the V2I feature you must first be subscribed to Audi Connect Prime services, Selected 2017 and 2018 Audi models support V2I along with all 2019 models except for the A3, TT and R8.
