A Review of the Comprehensive Application of Big Data, Artificial Intelligence, and Internet of Things Technologies in Smart Cities

Abstract

As global populations rise and urbanization intensifies, cities face significant challenges in sustainable development. Leveraging next-generation information technologies, particularly Artificial Intelligence (AI), machine learning, Big Data, and the Internet of Things (IoT), is essential to enhance urban operational efficiency and livability. This paper provides an in-depth analysis of the current applications and future trends of these technologies in smart cities, covering urban planning, intelligent transportation, environmental protection, and energy management. By integrating these technologies, smart cities can manage urban resources more effectively, improve residents' quality of life, and promote sustainability. Key issues and challenges are also discussed, providing a roadmap for future research and development.
