Density based traffic control system implementation using Arduino micro-controller board

Abstract

This paper gives the design of the density-based traffic control system implementation using Arduino micro-controller board. Traffic congestion is a severe problem in most of the cities across the world and it has become a nightmare for the citizens. It is caused by delay in signal, inappropriate timing of traffic signaling etc. The delay of traffic light is hard coded and it does not depend on traffic. Therefore, for optimizing traffic control, there is an increasing demand in systematic quick automatic system. This paper is designed to develop a density based dynamic traffic signal control. The signal timing changes automatically on sensing the traffic density at the junction. The microcontroller used in this project is ARDUINO. The system contains Ultrasonic sensors (trigger and echo) which will be mounted on the either side of the road on poles. It gets activated and receives the signal as the vehicles passes close by it. The work presented here is the mini-project work of the second sem students of electronics & communication engineering department of Dayananda Sagar College of Engg., Bangalore.
