Smart Traffic System Using Infrared Sensors-based IoT

One of the main problems in the intersection or cities of Iraq is that all people suffer from long waits, unexpected accidents, and environmental pollution at a time when developed cities seek to reduce it. Holy Karbala is one of the most important intersections in the middle of Iraq, it is always crowded due to the anniversary of millions of pilgrims (visitors). It was the proposed case study. Therefore, relying on cloud and Internet of Things (IoT) technologies, this study designed and implemented an intelligent traffic control network based on an intelligent programming control algorithm by utilizing sensors to improve the existing traffic network. This article presented a variety of challenges that it addressed. The results showed that a green signal takes three seconds to travel from one traffic light system to another. All five recommended scenarios were implemented, as described in the research details (TLS1, TLS2, TLS3, TLS4, and ring state) as the system is characterized by efficient response, ease of implementation, and satisfactory results with low cost (two types of microcontrollers (48 $) and infrared (IR) sensors ($3.54 per piece)) and without the difficult challenges associated with the curriculum as in the previous studies.
