2017 Cadillac CTS Demonstrates V2I Technology


2017 Cadillac CTS performance sedans have successfully demonstrated vehicle-to-infrastructure (V2I) technology in a test on Michigan roads.

As previously reported by Edmunds, beginning in March, the CTS began coming standard with vehicle-to-vehicle (V2V)  technology, which allows the Cadillac to communicate wirelessly with other V2V-equipped vehicles and warn drivers of potential dangers ahead on the road. Now, in this recent test, CTS development vehicles received information directly from traffic-signal controllers, alerting the driver of safety, mobility or environment-related conditions before they could become an issue.

The traffic signals, located adjacent to the GM Warren Technical Center campus, were able to send real-time data using dedicated short-range communications (DSRC) protocol to the development vehicles, which alerted the drivers of a potential red light violation at their current speed. This alert helps drivers avoid making the potentially dangerous decision of either braking abruptly or accelerating through a busy intersection.

The U.S. Department of Transportation (DOT) refers to V2I as "the next generation of Intelligent Transportation Systems" and notes that state and local agencies are likely to begin installing the necessary infrastructure alongside their existing systems in the near future. The DOT anticipates that V2I, V2V and other connected-vehicle technology will result in significant improvement in traffic safety and efficiency, especially if the vehicles "can respond automatically to roadway conditions reported by roadside equipment or other roadway users," without the need for driver intervention.

Unlike V2I, which will require infrastructure that is capable of DSRC transmissions, the Cadillac V2V system uses existing GPS technology for positioning and in-car DSRC communication to transfer information between vehicles. This allows the technology to work now, as long as nearby vehicles are similarly equipped.

For the moment, V2I technology is still largely experimental, with a number of municipalities, researchers and automakers working on its development. But, as Cadillac says, the successful CTS demonstration, as well as other tests, "lays the groundwork for a connected, safer future."
