Cars are prone to accidents with pedestrians on the zebra crossing when turning on a green light. Therefore, I design the warning function on the traffic light.
When the route is safe for pedestrians, the traffic light will cast a green light, and it will turn yellow when the route becomes dangerous for pedestrians to take. The red light casted from the side can warn pedestrians when the vehicle hits it, and the traffic light will predict the route the vehicle might pass by and cast a yellow light.
