Abstract—Traffic congestion is a significant issue in urban areas, leading to increased travel time, fuel consumption, and environmental pollution. This project introduces an adaptive Traffic Light Control System that dynamically prioritizes traf- fic direction based on real-time vehicle counts obtained from cameras. The system ensures efficient traffic flow by allocating green light duration proportionally to the vehicle density in each direction while maintaining fairness through a minimum green time of 3 seconds for all directions. The implementation includes a clockwise rotation of the green signal, preventing any direction from being perpetually delayed. The maximum green light duration is capped at 75 seconds to maintain system balance and efficiency. The results demonstrate improved traffic clearance, reduced waiting times, and significant optimization in signal utilization, making this system an effective solution for modern traffic management challenges.
