Cadillac Tests its Vehicle-to-Infrastructure Tech on Public Roads

Cadillac already sells one of the first production vehicles in the world with Vehicle-to-Vehicle communication technology as standard kit, but now the brand boasts it can talk with traffic signals too. 

In partnership with Michigan road agencies, a fleet of Cadillac CTS development mules showed off GM’s Vehicle-to-Infrastructure technology by receiving real-time traffic signal data in a demonstration on public roads located near GM’s Warren Tech Center.

V2I technology allows vehicles to “speak” with surrounding infrastructure, alerting the driver of safety, weather and traffic conditions ahead.

Traffic signals at the intersections of 12 Mile and 13 Mile roads in Warren, Michigan, sent real-time data using Dedicated Short-Range Communications (DSRC) to the prototype Cadillacs, notifying drivers they would need to slow for a red light at the upcoming intersection based on the vehicle’s current speed and the traffic signal’s timing.

Cadillac says it’s V2I system works similar to its V2V technology, which uses GPS for positioning and DSRC to send and receive up to 1,000 messages per second, from up to 1,000 feet away.

GM assures the vehicles will not transmit any identifying information like VIN number or the car’s media access control address, meaning the smart infrastructure won’t be able to snitch on cars that break the law. The automaker also promises other cybersecurity measures have been taken to ensure DSRC signals between the vehicle and the infrastructure can’t be fiddled with by outside parties.

The test was put on in collaboration with the Michigan Department of Transportation and the Macomb Country Department of Roads to showcase the state’s budding leadership in the competitive connected car space.
