A new study proposes that adding a white light to the existing green, yellow, and red traffic lights could accelerate traffic flow and enhance safety for both vehicles and pedestrians. Since the introduction of traffic lights in the 1920s, advancements in technology have created a need for change.
Four-color traffic signal: Could it reshape traffic flow and safety?
The emergence of autonomous vehicles marks a new era in traffic lights and general traffic management systems. These vehicles not only drive themselves but also communicate with each other and a central traffic computer system to improve traffic flow.
A research team from North Carolina State University suggests adding a white light to the traditional traffic light colors as autonomous vehicles increase. This new four-color system, known as “white light,” can improve traffic flow by 25% for both vehicles and pedestrians.
The white light implies human drivers following autonomous vehicles, allowing these vehicles to optimize traffic flow. It also involves integrating pedestrians into the traffic flow and developing meaningful signals for them.
The researchers are creating a testbed to test this new system in the real world. These tests will help understand the practical challenges without using full-scale vehicles. The research team is open to collaborating with industry and research partners to develop and implement these technologies.
Four-color traffic lights offer an innovative approach to enhancing traffic safety and flow for both vehicles and pedestrians. Designing and implementing the white light in a way that is meaningful for pedestrians can create a safer traffic environment for all.
The increasing use of autonomous vehicles and technological advancements in traffic management systems make the implementation of this new system feasible. However, how this new system will function in the real world and its practical application remains a topic of curiosity.
