Raspberry PI Based Internet of Vehicles for Traffic Management by Using PI Camera

Abstract

Internet of Things (loT) is a world-wide network connecting all the smart objects together. It is the way in which all things are enabled to talk with each other. Whenever those smart things being connected over internet are restricted to only vehicles, then it is called as Internet of Vehicles (loV). With continuously increasing urban population and rapidly expanding cities, vehicle ownership has been increasing at an exponential rate. Hence, traffic management has become a great problem in our day life. This project provides efficient traffic management solution to overcome the problem that is prevailing in our daily life. Wi-Fi (Short for Wireless Fidelity) is a wireless technology that uses radio frequency to transmit data through the air. Wi-Fi has initial speeds of 1mbps to 2mbps. Wi-Fi transmits data in the frequency band of 2.4 GHz. It implements the concept of frequency division multiplexing technology. Range of Wi-Fi technology is 40-300 feet. The Raspberry Pi is a low cost, credit-card sized computer that can be used in electronics projects. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games. In this project USB camera is connected to the Raspberry pi processor. Raspberry pi processor stores the images in the Hard disk (or SD card). Pressure sensor is attached to the tires of the vehicle, continuously checks the pressure in the tire. IR sensor is used to detect the vehicle presence and calculates the distance of the vehicle from our vehicle. If other vehicle is so close to our vehicle, then processor turns OFF the motor driver and the vehicle stops. Lock is attached to the vehicle and the vehicle does not move until correct password is entered. The images and the pressure in the tire are constantly monitored in the Android phone through Wi-Fi module.
