Contributing Writer Published May 18, 2026 7 min read Traffic lights are critical components in autonomous driving systems, smart intersections, and driver assistance applications. Some studies estimate that self-driving vehicles could help prevent up to 90% of traffic accidents by reducing human error, but this depends heavily on accurate real-time computer vision systems capable of detecting traffic lights, pedestrians, vehicles, and road signs under varying conditions. This variation helps the model generalize effectively during real-world inference...
