Introduction
Technology has been one of the most significant drivers of urban transformation throughout history. From the invention of the wheel and the development of railways to the emergence of artificial intelligence (AI), Geographic Information Systems (GIS), smart infrastructure, and digital twins, technological advancements have continuously reshaped the physical structure, function, and spatial organization of cities. Urban form refers to the physical layout and spatial characteristics of a city, including its land-use patterns, transportation networks, building density, open spaces, and infrastructure. Each technological revolution has altered the way cities are planned, built, managed, and experienced.
