The U-turn Safety System project aims to improve road safety by signaling vehicle presence near speed breakers during U-turns. It employs an LED and buzzer mechanism powered by a 12V battery to provide both visual and auditory alerts. When a vehicle approaches a speed breaker, the system activates using an open and close circuit concept, triggering the LED to light up and the buzzer to sound. This alerts drivers and pedestrians of nearby vehicles, reducing collision risks during U-turns.

6. Open/Close Circuit
When a vehicle approaches a speed breaker, the system detects the presence of the vehicle, closing the circuit. This action enables the flow of electricity from the 12V battery to the LED and buzzer. The LED lights up, providing a visual indication to nearby drivers and pedestrians, while the buzzer emits a loud sound as an auditory warning. Together, these alerts help signal the potential movement of vehicles, reducing the risk of collisions during U-turns in busy areas.
When no vehicle is present near the speed breaker, the circuit remains open, keeping the system inactive to conserve power and avoid unnecessary alerts. The simplicity of the open and close circuit design makes this system easy to implement and cost-effective. The U-turn Safety System can be particularly useful in areas with high traffic or limited visibility, where U-turns near speed breakers pose a significant safety concern.
