Which urban models are most often used to explain polycentric urban regions beyond the CBD?

• A. Burgess Model and Hoyt Model.
• B. Harris-Ullman Multiple Nuclei Model and Griffin-Ford Latin American City Model.
• C. McGee Southeast Asian City Model.
• D. Central Place Theory.

Answer: (B)

The main idea being tested is how cities become organized around multiple centers beyond the central business district. The best choice brings together two models that specifically describe this polycentric, multi-nucleus structure. The Harris-Ullman Multiple Nuclei Model explains that as cities grow, different centers emerge for different activities—commerce, industry, housing, etc.—so the urban area develops several nuclei rather than a single CBD. This decentralized pattern captures how real cities often function: people, transportation, and land uses cluster around several hubs. The Griffin-Ford Latin American City Model adds another angle by describing Latin American cities with a dominant CBD but also pronounced secondary centers along a commercial spine, plus distinct residential zones and informal areas. This model illustrates how a city can be organized around multiple focal points beyond the core, driven by social and economic sorting along the spine and periphery. Other options fit monocentric ideas or different spatial concepts. Burgess and Hoyt describe cities with a single center (even if shaped differently), Central Place Theory maps market areas rather than urban form, and the Southeast Asian model is region-specific and less universally invoked for polycentric explanations.
