Accident Prevention Technology in Hilly Terrain

      

          In hilly regions, there will be a number of curves and hairpin bends. The roadway is one of the often-used modes of transport in these regions. Accident rate and death rate in hilly regions are increasing day by day. The roads in this region will definitely have bends and steep curves; hence, it is difficult to see the vehicles coming from the opposite side. The proposed system aims in reducing the risk of driving vehicle in the terrain region with hairpin bends and steep curves

Components Required.

 1. Microcontroller (Arduino UNO) 

2. Ultrasonic sensors

 3. Buzzer 

4. Red & Green LEDs. 

5. Resistor. 

6. Vero Board. 

7. DC Generator. 

8. Battery. 

9. Switch. 

10. Connecting Wires. 

11. Ply Board. 

12. Toy car.

 Circuit Diagram

Working 

The Micro-controller with ultrasonic sensor senses the vehicle coming towards the bend and intimates it to the other side of the bend or curve, it gives three stages of LED alerts to the driver driving the vehicle from the opposite side of the hairpin bend or curve.

Conclusion 

         The system was able to alert the vehicle approaching in the opposite direction of curve, hairpin bend or a blind spot to reduce the accident rate in hilly regions. The system shall help in saving many lives which are lost due to accident in these difficult hilly terrains.
