Accident prevention system for hairpin bend zone in hills

accident-prevantion-featrured.jpg

Observing problems and trying to find a solution for it is one step towards creating a genius.

Let’s explore a common problem which we face while driving on hills particularly at hairpin curves and blind corners when the driver is sceptical if a vehicle is arriving from the other end of the corner.

Ever thought of how safer it would be by knowing if there is another vehicle coming from the other side of a blind corner.

So put your creative hats on and see how we can make use of our Havi Elements to create a solution for this.

Power – 2

IR – 2

LED – 2

Buzzer – 2

Accessories:

The making

This project is created in two sections:

  1. First we create the circuit using Havi Elements.
  2. Second, we create a blind turn scenario using our crafting skills.

Section 1: Creating the circuit.

IR (Infrared) sensors are used to detect the presence of the object. Checkout How IR works for more details.

Coupling IR sensor with Buzzer and LED will make the buzzer emit sound and LED glow whenever an object is detected by the IR Sensor.

Snap the elements to prepare the circuit as show here.

Now your circuit is ready and you can check by keeping an object closer to the IR sensor if the buzzer and LED works well. You can adjust the sensitivity of the IR sensor using the controller provided in the element.

Section 2: Creating a blind corner scenario.

A hairpin bend or blind corner is a turn on the road where the view of what is behind the corner is obstructed either by buildings, hills or trees. Warning signs are often placed on such roads to warn traffic.

You can watch the videos and photos provided in this blog and also search for other images of blind corners over the internet and create a scenario using your crafting skills to demonstrate the working.

IMPORTANT: Note the placement of the IR Sensors and the associated buzzers and led lights in your model.

Once you have created the scenario, get two toy cars and demonstrate the working.

How it works?

The IR sensors are placed on the left lane of either sides of the curve.

As car approaches the curve, it is detected by the sensors placed their and a notification LED glows on the other side of the curve with a buzzer sound to alert the traffic coming form that side about the approaching car.

This works on both the sides of the curve.

This notifies the driver about the vehicles approaching from the other side of the blind corner. The driver then can carefully take the turn and ensure a pleasant and safe journey.

Advantages when implemented in the real world

Accidents can be prevented and a lot of lives and loss of vehicles can be saved when implemented at hairpin curves in the real world.
