Don’t Expect White Traffic Lights in Pittsfield Anytime Soon

Researchers from North Carolina State University have a bold vision for the future of traffic: a fourth traffic light color. White lights, specifically designed for autonomous cars, could soon appear at intersections across the country. In the Berkshires, where we're still patching potholes and trying to get more Uber divers.

Here's the deal: when enough self-driving cars approach an intersection, a white light turns on. Human drivers wouldn't need to think, just follow the autonomous car in front of you. These cars communicate with each other and the traffic light in real time, coordinating speeds and movements to keep traffic flowing smoothly. When the autonomous cars move on, the white light turns off and everything goes back to the traditional red, yellow, and green we all know. -unionrayo.com

The researchers claim this system could reduce traffic jams and cut delays. In tests where only 10 percent of vehicles were autonomous, delays dropped by 3 percent. Imagine a future where most cars are self-driving, traffic jams could become a thing of the past. Fewer jams mean less fuel burned, lower emissions, and, most importantly, less road rage.

But let's pump the brakes for a second. This is a long way from becoming standard in rural areas like the Berkshires. Autonomous vehicles are still rare outside of major cities and tech hubs. Tesla's autopilot features have made headlines, sure, but full self-driving cars navigating winter weather, winding mountain roads, and the occasional black ice patch? That's a bigger challenge.

The initial testing for white traffic lights will likely happen in controlled environments, places like ports, where traffic patterns are predictable and pedestrian activity is minimal. Cities with heavy autonomous vehicle usage, like San Francisco or Phoenix, could follow. But smaller communities? We'll be waiting a while. I mean, we did just get some new flashing yellow arrows a few years back!
