In urban traffic systems, providing a clear and quick path for emergency vehicles like ambulances and fire trucks is critical for saving lives and ensuring public safety. This project presents the design and implementation of an Emergency Traffic Light Controller using Radio Frequency (RF) modules and Arduino Uno. The system enables emergency vehicles to override standard traffic light operation by transmitting an RF signal to the traffic controller. Upon receiving the signal, the controller imme-diately switches the traffic light to green in the direction of the approaching emer-gency vehicle, while setting all other directions to red. This allows the emergency ve-hicle to pass through intersections without delay. The system returns to normal opera-tion once the vehicle has passed. The proposed solution is cost-effective, easy to im-plement, and significantly improves response times for emergency services while maintaining overall traffic safety.
