White Light Addition Boosts Traffic Flow for AVs and PedestriansNew Traffic Light System Increases Efficiency and Safety

Prepare to leave your comfort zone if you're accustomed to the familiar red, amber, and green traffic lights. Recent findings have indicated that the addition of a white light can greatly enhance traffic flow and safety for both drivers and pedestrians.

For decades, the color-coded traffic signal system has been in place, with red as the universal stop signal, green for go, and amber as a warning to slow down or speed up. This system has been refined over the years, from the use of semaphore signals to electric lights and then to computerized systems that can analyze traffic patterns and adjust timing accordingly. With the rise of autonomous vehicles (AVs), however, a new element has been introduced.

AVs not only have the ability to self-drive, but they can also communicate with each other and a central traffic computer system. As a result, they can act as part of the traffic control system to enhance flow and efficiency. A team of researchers from North Carolina State University has proposed adding a fourth, white signal light to the traditional trio of signals, which would allow AVs to work together to improve traffic flow even further.

In their previous study, the team found that the addition of the white light could significantly speed up movement through intersections. In their latest research, they incorporated pedestrian traffic into their computer model and found that the flow of both vehicles and pedestrians improved by over 25 percent with the use of the white signal.

However, there are still many challenges that need to be addressed before this system can be put into practice. One major hurdle is having enough AVs on the road to make the system effective. Additionally, installing the necessary four-light signals and getting human drivers to trust the new signal will also be key factors.

To test their concept in the real world, the team is currently setting up a physical testbed using small-scale vehicles. This will help them identify any challenges and make necessary adjustments before implementing the system on a larger scale. They also hope to work with industry and research partners to explore ways to move forward with this technology.

One potential issue that may arise is how to incorporate the new white light into the familiar children's songs about traffic lights. Perhaps a new version could go something like, "Follow the autonomous car in front of you, if there is one, and cross the road too if you want to, or otherwise just stay where you are, says the white light." It may not have the same ring as the classic, but it's a small price to pay for improved traffic flow and safety. The study was published in Computer-Aided Civil and Infrastructure Engineering.
