Accident Alert System

Abstract

This paper focuses on enhancing road safety at blind turns by
detecting vehicles approaching from either the left or right side
using ultrasonic sensors. Blind turns present significant
challenges for drivers due to obstructed visibility, increasing
the risk of accidents. The system uses two ultrasonic sensors
positioned on both sides of the turn. These sensors detect the
presence of vehicles approaching from the left or right and relay
the information to a central controller.
Upon detecting a vehicle, the system triggers a voice synthesizer
to audibly alert the driver and displays the corresponding
vehicle's position (left or right) on an LCD display. Additionally,
red and green LEDs provide visual indicators: red signals an
approaching vehicle, while green signifies a clear path.
