Arduino Based Traffic Monitoring and Controlling System

Abstract

Nowadays, controlling the traffic becomes major issue because of rapid increase in automobiles and also because of large time delays between traffic lights.to optimise this problem we have made a frame work for an intelligent traffic control system. Sometimes higher traffic density at one side of the junction demands longer green time as compared to standard allotment time we, therefore propose here a mechanism in which the time period of green light and red light is assigned on the basis of the density of the traffic present at that time . Once the density is calculated ,the glowing time of a green light is assigned by the help of microcontroller(Arduino). The sensors which are present on sides of the roads will detect the presence of the vehicles and sends the information to the microcontroller where it will decide how long a flank will be open or when to change over the signal light. This project explains you how to control the traffic based on density. In this system, we will use IR sensors to measure the traffic density. We have to arrange one IR sensor for each road, these sensors always sense the traffic on that particular road .All these sensors are interfaced to the microcontroller .Based on these sensors, controller detects the traffic and controls the traffic system.
