Cadillac Successfully Tests Vehicle-to-Infrastructure Technology in Michigan
Cadillac announced on Tuesday that its V2V communications-capable CTS sedan has successfully demonstrated its vehicle-to-infrastructure (V2I) communication capabilities during public testing in Michigan.
Working with the Michigan Department of Transportation and Macomb Country Department of Roads , Cadillac R&D demonstrated its CTS development vehicles’ V2I functions by receiving data relating to phasing and timing from traffic signals at the intersections of 12 Mile and 13 Mile near the GM Warren Technical Center Campus.

Earlier this year, Cadillac announced that the 2017 CTS sedan will come standard with General Motors’ V2V safety technology. Utilizing Dedicated Short-Range Communications and GPS, the CTS sedan is capable of receiving up to 1,000 messages per second from vehicles as far as 1,000 feet away.
The acquisition of data from other vehicles on the road is intended to help drivers avoid road conditions and hazards that could increase the likelihood of a collision, up to and including slick surfaces and disabled vehicles.
Similarly, V2I technology allowed the CTS development vehicles to determine whether they were at risk for running a red light at their current speed. Notifying drivers of upcoming red lights by reading signal phases and timing allows them to avoid having to make a split-second decision that could lead to a sudden braking situation or a potential ticket.
As is the case with Cadillac’s V2V technology, V2I does not allow the vehicles to transmit sensitive information such as VIN, registration, or MAC addresses. As such, if a vehicle equipped with V2I were to run a red light, the data collected by the traffic signal would not provide any specific details about the vehicle or driver.
