City models are simplified representations of urban areas, used to analyze and visualize the layout and structure of cities. They can take various forms, including physical models, digital simulations, or maps, and help urban planners, architects, and researchers understand spatial relationships and land use patterns. These models often highlight key features such as transportation networks, residential zones, and commercial areas. By studying city models, stakeholders can make informed decisions about development, zoning, and infrastructure improvements, ultimately aiming to enhance the quality of life for residents in cities like New York or Tokyo.
