An IoT Based Automated Traffic Control System With Real-Time Update Capability

An automated microcontroller based traffic control system using sensors along with live web updates can be a helpful step in optimizing the traffic flow pattern in busy intersections. This intuitive design of the transport infrastructure can help alleviate the traffic congestion problem in crowded cities. This paper describes a system where ultrasonic sensors are integrated with the Raspberry Pi to operate the lanes of an intersection based on the density of traffic. The current condition of the intersection is updated on a user accessible website. This integration of traffic systems in an Internet of Things (IoT) fashion enables the addition of smart security and road safety devices. As a result, the improvement in traffic system can be incrementally enhanced, which can lead to eventually significant improvement in the overall traffic system.
