An Intelligent Traffic Signalling System based on Integration of an Arduino and Infrared Sensor

Currently, traffic lights operate according to a predetermined timetable, which might cause issues if certain lanes are empty while others are congested. To fix this, we came up with a smart traffic system. Our method proposes leaving the green light on longer than usual when there are a lot of automobiles on one side of the road. To determine this, we employ specialized sensors known as PIR sensors. A tiny computer called an Arduino control how many cars are allowed to pass and how long the green signal lasts. The Arduino determines when to change the lights by using sensors along the road to determine whether there are any cars nearby. In the parts that follow, we will go over every detail of how this system operates. Our project’s primary objective is to create a traffic system that can automatically adjust the lights at an intersection according to the number of cars there. We believe that it is time to replace the outdated light timing system with a new autonomous system, as traffic congestion is a major issue in cities worldwide.
