Smart Acoustic Siren Detector For Priority Emergency Vehicle Path Clearance At Intersections

🚦 Emergency Vehicle Priority Traffic Control System 📌 Project Overview The Emergency Vehicle Priority Traffic Control System is an Arduino Uno based smart traffic management project designed to provide immediate road clearance for emergency vehicles such as ambulances, fire trucks, and police vehicles. In normal operation, the traffic lights follow a standard timing sequence. When an emergency vehicle approaches an intersection, the corresponding emergency button is pressed, instantly giving priority to that road by turning its signal green and all other conflicting signals red. This helps emergency vehicles pass through intersections quickly and safely without waiting for normal traffic signal timings. 🎯 Objectives Reduce delays for emergency vehicles. Improve road safety at intersections. Demonstrate smart traffic control using Arduino. Provide a low-cost and simple traffic management solution. 🛠 Components Used Arduino Uno Breadboards 6 LEDs (2 Red, 2 Yellow, 2 Green) 6 Current Limiting Resistors (220Ω) 2 Push Buttons Jumper Wires USB Cable / Power Supply ⚙ Working Principle Normal Mode Road 1 Green → Road 2 Red Road 1 Yellow Road 1 Red → Road 2 Green Road 2 Yellow Cycle repeats continuously Emergency Mode If Road 1 emergency button is pressed: Road 1 immediately turns Green Road 2 immediately turns Red If Road 2 emergency button is pressed: Road 2 immediately turns Green Road 1 immediately turns Red The system interrupts the normal traffic sequence and instantly provides priority to the selected road. 🚑 Emergency Scenario Consider an ambulance carrying a critical patient approaching an intersection. Without this system: The ambulance must wait for the current traffic signal cycle. Valuable time may be lost. With this system: The emergency button is activated. The traffic signal immediately changes. The ambulance receives a clear path. Response time is reduced significantly. ✅ Advantages Fast response for emergency vehicles.
