How It Works: Traffic Light Sequence: Our setup uses BC547 transistors to control the traditional red, yellow, and green traffic lights, allowing them to operate in a seamless sequence.
Blue LED Congestion Indicator: The key feature of our system is the blue LED, which lights up to indicate traffic congestion.
IR Sensor Modules: We have installed three IR sensor modules along the road. These sensors detect the presence of vehicles.
Relay Modules: Each IR sensor is connected to a relay module. When all three sensors detect vehicles simultaneously, they activate their respective relays.
Congestion Detection: Once all the relay modules are active, the blue LED lights up, indicating that the road is congested. If any one of the relay modules is inactive, it means there is space on the road, and the blue LED remains off, indicating that traffic is flowing smoothly.
Benefits: This project provides real-time traffic updates, helping drivers make informed decisions and allowing authorities to manage traffic more efficiently.
