What are the benefits of traffic lights?

1. Effectively control and manage intersections with large traffic flow ; 2. Reduce traffic conflicts, enhance traffic safety, and increase traffic capacity at intersections ; 3. The distribution of the right of way is more fair, reasonable and efficient; 4. Traffic light control can reduce the accident of right-angle collision at the intersection; 5. At signal-controlled intersections, pedestrians can pass more safely through crowded roads than at unsignaled intersections.
