Researchers are proposing the addition of a white light to traffic signals to communicate with autonomous vehicles, allowing them to better coordinate with human drivers and improve traffic flow.
The new color could help optimize traffic patterns by giving priority to autonomous vehicles, which can react faster and make more precise driving decisions, thus reducing congestion.
As self-driving and human-driven cars share the road, the extra light could serve as a signal for human drivers to follow the lead of autonomous cars, ensuring smoother coordination in mixed-traffic environments.
By giving clear signals to both human drivers and autonomous vehicles, the new color could reduce confusion at intersections, potentially leading to fewer accidents and safer roads.
If implemented, the new light could be gradually adopted worldwide, first in regions with a high concentration of autonomous vehicles. This would require updates to traffic light systems and regulations across many countries.
Introducing a new color would require significant public education campaigns to ensure that all drivers, whether in autonomous or traditional vehicles, understand its meaning and how to respond.
The introduction of a new traffic light color would come with technological challenges, including the cost of upgrading traffic signals and retrofitting vehicles to recognize the new color, which could slow down widespread implementation.
