Smart Accident Prevention at Hairpin Bends Using Sensor-Based System

Accidents are repeated in many countries and people suffer. Mountain roads and the curved ones are among those that have accidents frequently. In these conditions there are roads which have sharp turns and as a result the driver has no visibility of the vehicles in the opposite lane. These are the places where everyone needs to be careful and intelligent enough. This problem is to inform the driver about the problem causing the object in the opposite direction. This can be achieved by installing an ultrasonic sensor on one side of the road before the curve, and positioning an LED light and buzzer on the opposite side after the curve. When a vehicle is detected by the sensor, the LED light and buzzer will be activated on the other side of the road.
