Smart and adaptive traffic light system

Traffic congestion is still a substantial issue among both developed and developing countries. With the strong development of science and technology, scientific and technical achievements are applied through various means in life. A traffic light system is one of those significant achievements. It is a system of signaling lights to guide vehicles and people in traffic at the nodes. Through means of research of the similar categories for this project, adaptive traffic lights are known to be established to give citizens a huge advantage in allowing them free time in traffic, which is distinctly important in our ever changing and technologically advanced age. The goals of this thesis were to deepen the understanding of smart traffic automation principle to optimize the current traffic system through researching and programming, with a chance of implementing the results for future applications. To analyze the hypothesis that an adaptive system prompts a smooth and effortless traffic flow, a program in TIA Portal was designed to reproduce the traffic flow of an intersection through virtual inputs with arrays of functions ranging from normal and busy traffic to priority pass for emergency vehicles. The results through the research and programming with TIA Portal processes illustrate better knowledge and view about adaptive traffic lights with the research about the subject and also a functioning simulation of an intersection that works in multiple settings of traffic which could be used as reference for HAMK campuses
