Abstract: With ever increasing number of vehicles, traffic congestion has become a major problem faced in most of the metropolitan cities across the world and therefore traffic automated system with decision making capabilities must be implemented. The objective of the project is to build a traffic control system where the signal changes automatically by sensing the traffic density at any junction. The vehicle congestion at the junction, is regulated with the help of infrared sensors which interface with an Arduino mega controller. In order to obtain an accurate density, each lane is incorporated with two IR sensors. This in turn regulates the traffic consistently and in an automated manner, thereby improving the effectiveness of the system.

Keywords: Traffic congestion, Vehicle detection, Infrared sensors, Arduino-controlled.
