We have ALL been through this. You are driving and come up on a yellow light and think you can make it then BOOM!
Well Cadillac has come up with a solution.
The V2I test comes after the luxury automaker rolled out a feature to enable vehicle-to-vehicle (V2V) communication back in March, which made its 2017 CTS sedan the first car on the market with the ability to "talk" to other enabled vehicles in its vicinity by sending data about road conditions back and forth through a connected system.
Cadillac tested out the V2I system by rigging two traffic signals near the GM Warren Technical Center campus to send data to its demo CTS vehicles. The automaker said the stop lights were able to use Dedicated Short-Range Communications (DSRC) protocol — which is the same system used for inter-car V2V communication — to send data to the cars about when the light would turn red.
The car was then able to alert its driver if their current speed might create an issue at the intersection.
V2I should help to create interconnected smart cities — but for the systems to really grow, more municipalities will need to partner with automakers to build the roads of the future.
