The traffic in Paris, France, has always been famously congested, not only the number of cars but also the pedestrians and bicycles. Especially at a certain intersection, there are more people and vehicles vying for the road. Earlier, the government piloted a traffic safety device in the 15th arrondissement of Paris, which involved adding “ground LED lights” guidelines at traffic light intersections. It is estimated that the effect is extremely significant.
This intersection is located at a crossroad outside Porte de Sèvres. Because of the car lane plus the light rail and the subway terminal, there are many people and vehicles, and it is always very busy. There are LED lights on the ground on both sides. As long as the green light for pedestrians is on, the LED lights will follow to turn green, and if it is red for pedestrians, it will turn red. The original intention of this move is to remind pedestrians who often bow their heads and play with their mobile phones, even if they keep their heads down, they pay attention to the lights. Later, a ground light was added to remind vehicle drivers to be careful of pedestrians (there are cars passing by like a pedestrian green light). Due to the positive response after the trial, the government is considering implementing it in Paris and the whole country to improve traffic and reduce accidents.
