Red, yellow, green ... and white? Smarter vehicles could mean big changes for the traffic light

Advancements in vehicle technology could lead to significant changes in traffic signal systems, potentially phasing out the traditional red, yellow, and green lights. Researchers, such as those from the University of Michigan and North Carolina State University, are exploring how connected and autonomous vehicles can improve traffic flow and safety. Some propose adding a new signal light or altering existing ones to accommodate the capabilities of smarter vehicles. These changes, while still years away, could revolutionize how traffic is managed, relying more on vehicle data than on traditional infrastructure.
