A traffic safety approach has shown promise in reducing crashes and injuries. By using speed sensors, drivers who follow the rules are rewarded with more green lights. This method has led to a significant decrease in accidents along a certain road.

Further details are available about this traffic safety concept. It involves traffic signals that remain red until a vehicle is detected. Some cities have built upon this idea by incorporating speed sensors to give earlier green lights to drivers obeying the speed limit.

The effectiveness of this approach is attributed to its ability to encourage good driving habits, rather than solely focusing on punishing bad ones.
