Final answer:
The question is concerned with urban development and the factors that influence city growth, such as transportation, industrial corridors, and historical factors. Cities without robust public transportation systems developed with multiple smaller business districts as opposed to a single concentrated CBD. Urban structure models like the Sector Model and Multiple Nuclei Model explain the spatial organization of such cities.
Step-by-step explanation:
The subject of this question pertains to urban development and how city growth patterns are influenced by various factors such as transportation systems, industrialization, and historical development. In cities like Los Angeles, Dallas, and Phoenix that lack efficient public transportation, the urban landscape evolved with multiple small business districts or nuclei instead of a dense Central Business District (CBD). These cities developed differently from older, rail-oriented cities in the Northeast and Midwest where public transportation systems allowed the CBD to be the dominant center. Highways and automobiles facilitated different types of residential and commercial growth, leading to the creation of New City Ghettos that are linear in shape and a decentralized pattern of industrialization due to less rigid zoning laws, particularly in the American West. Models of urban structure, such as the Sector Model proposed by Homer Hoyt and the Multiple Nuclei Model, attempt to explain the spatial arrangement of cities by taking into account elements like transportation routes, industrial corridors, and residential zones. These models highlight the importance of factors like accessibility, amenities, and environmental conditions in determining where different urban land uses are situated. Moreover, the historic development of streetcar suburbs and the clustering of industrial activities around modes of transportation further shaped the urban landscape.
