Design and implementation of traffic density controller using wireless communications

Abstract

In large urban areas, vehicular traffic has been increasing day by day. As the number of road user’s increase constantly and current resources & infrastructures being limited; a smart traffic control will become a very important issue in the future. This paper introduces a system which works with AVR Microcontroller interfaced with IR sensors and photodiodes which are used to detect density of traffic. In this model three LED’s of different colors-RED, GREEN, YELLOW-have been used. For gauging the traffic density IR sensors have been used here and programming of the Microcontroller has been done on the basis of traffic density measurement. The microcontroller can be operated with the help of mobile app by connecting the controller with Bluetooth or Wi-Fi. This mobile app will on or off the traffic signals depending on the density of the traffic. This mobile app will allow the vehicles in high density traffic area to go first. So, this system solves problems like traffic jams, accidents etc and clear traffic for emergencies like ambulance vehicles and fire grade vehicles.
