T - Junction Blind Spot Indication System at Flyover, Metro and Bridges

Abstract

The integration of advanced technologies in vehicular safety systems has become increasingly crucial, particularly for addressing the persistent issue of vehicle blind spots at high-risk locations, such as T junctions and flyovers. These blind spots often lead to accidents due to compromised visibility. A promising solution is the use of ultrasonic sensor technology integrated with a microcontroller, such as Arduino, to detect and alert drivers to potential hazards in real-time.

Ultrasonic sensors, when strategically mounted around a vehicle, emit high-frequency sound waves that detect nearby objects by measuring the time taken for the waves to return. The Arduino microcontroller processes the sensor data to calculate distances and assess whether any objects are within a dangerous proximity. The system then alerts the driver through auditory signals, such as buzzers, and visual cues, including LEDs and an LCD display, ensuring that immediate attention is drawn to potential threats.
