Smart Traffic Junction Using Raspberry Pi

Abstract In present situation, use of vehicles is rapidly increasing all over the world, particularly in urban areas. In the recent years, the numbers of vehicles on roads are arising at an exponential rate. This increase is accomplished by the road accidents and signal jumping is the major cause. In future, a traffic control system of smart features is an important issue as the people using the road increase and the existing resources and infrastructures are narrow. An intelligent traffic control system is designed to overcome the increasing demand of all these essentials. A system should be designed to optimize the control of traffic. This paper will express the improvement of traffic reduction largely in a city. Management of traffic is a sturdy case. With several junctions, the difficulty enhances as the traffic state increases. By redefining the threshold values for a real time application, an excellent way of improving the traffic is proposed. By using RASPBERRY PI controller performing the processing of real time data obtained from sensors, Smart traffic junction using Raspberry pi based light control system is implemented as key role. This concept is that incoming vehicles at a traffic junction is outfitted with a retractable barrier. When there is red light at the traffic junction, the barrier rises and widely blocks the incoming vehicles and when there is green light at the traffic junction, the barrier retracts. Thus, this project will control traffic on four-way roads based on traffic control barriers. With this system, there will be less traffic jams, emergency vehicles will reach the destination in time and the country will be developed. So, this intelligent system will help us to control traffic in more autonomous way.
