City layouts refer to the organized arrangement of streets, buildings, and public spaces within an urban area. Common layouts include the grid pattern, where streets intersect at right angles, and radial designs, which feature roads radiating from a central point. These designs influence traffic flow, accessibility, and the overall functionality of the city. Different cities may adopt unique layouts based on geography, history, and cultural factors. For example, Paris has a radial layout centered around Place de l'Étoile, while New York City is known for its rectangular grid system. These layouts impact urban planning and the daily lives of residents.
