The model assumes that:
-There are urban land use zones of growth based on transportation routes and linear features like roads, canals, railroads, and major boulevards.
-There is a strong CBD.
-Similar land uses and socioeconomic groups clumped in geometric sectors radiating outward from the CBD along particular transportation routes.
-Many factories and industrial activities follow rail lines.
-Lower socioeconomic housing follows lines of public transportation, and sectors that service visitors are located along major highways.
2—Transportation route, ie. Railway
3—Low income sector—near industry, transportation.
4—Middle income sector—away from negatives of industry and transportation
5—upper income sector, along boulevard, shops, white collar services, close to lake/elevation??
A model of the internal structure of cities in which social groups are arranged around a series of sectors, or wedges, radiating out from the central business district (CBD)
Blends elements of traditional Latin American culture with modernization processes.
The framework of the idealized city is a composite of sectors and rings.
The heart of the city is the CBD dominated by reliance on public transportation and nearby concentrations of affluent, elite residents that guarantees a thriving central city.
A commercial—industrial spine extends the CBD in one direction with offices, shops, high-quality housing, restaurants, theaters, parks, golf courses,
Three zones reflect home of majority of residents—(1) the zone of maturity, attractive to middle classes with filtered-down colonial housing and improved self-built dwellings, (2) the zone of in situ accretion, modest housing interspersed with deterioration, and (3) zone of peripheral squatter settlements, housing for the impoverished.
Griffin-Ford model. Developed by Ernst Griffin and Larry Ford. Blends traditional Latin American culture with the forces of globalization. The CBD is dominant; it is divided into a market sector and a modern high-rise sector. The elite residential sector is on the extension of the CBD in the "spine". The end of the spine of elite residency is the "mall" with high-priced residencies.
The remaining concentric zones are more poor, including the outermost zone and the disamenity sector. The disamenity sector is usually run by gangs or drug lords.
Combines elements of Latin American Culture and globalization by combining radial sectors and concentric zones. Includes a thriving CBD with a commercial spine. The quality of houses decreases as one moves outward away from the CBD, and the areas of worse housing occurs in the Disamenity sectors.
