Abstract :

Traffic congestion and pedestrian safety are major concerns at road junctions in densely populated countries like India. This project presents an intelligent traffic light control system using IR sensors and a sound sensor for efficient traffic management. The IR sensors are used to detect vehicle density on each road and adjust signal timing dynamically. A sound sensor is integrated to identify emergency vehicles such as ambulances and fire engines. Upon detection, the system provides priority clearance to ensure faster and safer passage for emergency services. This adaptive approach reduces waiting time and improves overall traffic flow. The controller is designed to operate at high speed with reliable performance. The proposed system is implemented using Verilog hardware description language. Functional verification is carried out using a System Verilog-based testbench. The results demonstrate accurate operation and improved traffic control with enhanced pedestrian safety
