Cadillac doesn’t just excel in style and performance; it’s a champion in safety, too. The newest Cadillac safety technology will use communication to help drivers at red lights.
The technology is called V2I, meaning vehicle-to-infrastructure. This might sound similar to the already-existent V2V (vehicle-to-vehicle) communication. The difference here is that instead of vehicles communicating to other vehicles, traffic lights are communicating with vehicles.
Cadillac tested this innovative technology out near the GM Warren Technical Center, where they rigged two traffic signals to communicate with Cadillacs. Traffic lights are able to use something called Dedicated Short-Range communications, which is used in V2V. With this technology, the car can get information from traffic lights, and in turn, give the driver helpful information.
With V2I communication, Cadillac cars will be able to tell their drivers if their speed could cause a problem at an upcoming light. This is helpful for lights that are hard to see, or lights that don’t stay yellow for long.
Because V2I communication takes a bit more work than V2V communication, Cadillac isn’t quite sure how long it’ll take to spread across the U.S. But for now, the V2I system is available in some 2017 models and works in the city of Las Vegas. Hopefully soon it’ll work everywhere.
