AP HUG U6: Models

Those unit 6 models!! they'll definitely come up...

Concentric zone model

Made up of rings: CBD in the center, zone of transition (low-income housing), zone of middle class homes, zone of higher class homes, commuter zone (including the suburbs)

Outdated because? Globalization, advancements in transportation and changes in the layout of cities

Based on: Chicago

Hoyt sector model

Sectors extend outwards from the CBD: Connected to it is factories and low residential areas and middle/high residential areas

Outdated because? change in transportation systems, CBD is no longer as important, more personal vehicles

Based on: US cities

Multiple nuclei model

One large CBD with smaller nodes throughout the city (attracting different goods, services, and people). People live in areas of the city near their work and who also share a similar economic background

Outdated? No because it still represents an urban landscape

Based on: Chicago

Galactic city model

Focused on a service based economy with the CBD at the center. More advanced infrastructure along with a beltway to different edge cities/settlements

Based on: Detroit

Latin American model

CBD and market in the center. Surrounded are residential neighborhoods (some which are gentrified). Extending outwards is more wealthy businesses/settlements. Surrounding the city are informal/squatter settlements

Sub-saharan African city model

Includes three different CBDS: colonial, traditional, and market. Three roads separate the city, historically by segregation of the poorest to richest (ethnic and mixed neighborhoods). Outside of the central point are informal satellite townships and a manufacturing zone.

Outdated? Yes because it doesn’t apply to all of the post-colonial African cities

Southeast Asian city model

A port instead of a CBD due to the geography and rapid urbanization. Since the port is the center of commerce everything extends outwards from it: government and mixed-land use zone. Residential and industrial areas are farther away.
