The model emphasizes the importance of functional linkages between these realms.Ħ. It suggests that metropolitan regions consist of independent suburban areas or realms, each with its own distinct characteristics, including economic activities, housing patterns, and transportation systems. Dodge in 1960, this model considers the influence of suburbanization and the decentralization of urban functions. Urban Realms Model: Created by James Vance and Robert E. The model suggests that the size and spacing of these central places are determined by factors such as population, transportation networks, and market areas.ĥ. It proposes that cities and towns serve as central places that provide goods and services to surrounding areas. Central Place Theory: Developed by geographer Walter Christaller in 1933, this theory focuses on the spatial distribution of human settlements. Each nucleus functions as a focal point for specific activities and has its own transportation and service networks.Ĥ.

It suggests that urban growth is not solely dependent on the CBD but can occur around various specialized centers, such as industrial parks, university campuses, or entertainment districts. Multiple Nuclei Model: Introduced by geographers Chauncy Harris and Edward Ullman in 1945, this model recognizes that cities may have multiple centers of development or nuclei. According to this theory, certain sectors of the city become more attractive for certain activities or socioeconomic groups, leading to the formation of distinct land-use patterns.ģ. Sector Model: Proposed by economist Homer Hoyt in 1939, this model expands upon the concentric zone model by suggesting that cities develop in wedges or sectors rather than just concentric circles. The model suggests that different land-use zones develop based on their distance from the central business district (CBD), with the innermost zones characterized by higher density and more intensive land use, while the outer zones have lower density and more residential areas.Ģ.

Concentric Zone Model: Developed by sociologist Ernest Burgess in 1925, this theory proposes that cities grow outward from a central core in a series of concentric rings. It shows that the outer cities are not 'satellites' of the central city, but are in fact becoming cities themselves and shaping the metropolis.There are several theories and models that have been developed to understand and explain urban phenomena. This model does a good job at explaining suburban growth and how certain functions that are normally found in the central business district can be moved to the suburbsĩ What is it Used for? The Urban Realms Model constitutes the latest step in identifying and modelling the modern American urban structure.

The inter-accessibility across the individual suburban realms.ħ What does it Include? This model includes…Ī central city, which is the “new downtown” and the central business district A suburban downtown Edge Cities/Outer Realms An airportĨ Why was it Invented? The purpose of this model was to explain and predict changing urban growth patterns as the automobile became increasingly prevalent and large suburban “realms” emerged. The accessibility internally of each realm in regards to its major economic function. The amount and strength of the economic activity taking place within each of the realms. The physical terrain of the area, including water barriers and mountains. The model shows that the central business district is losing its dominanceĥ What is a Realm? A realm is a self-sufficient urban area with an independent focal point It is also referred to as an edge city Each realm of the model is separate and used for a different purpose, but are linked together to make one large, fluid city.Ħ The Nature of Each Realm is Based on 5 Criteria. Using this model, Vance was able to look at San Francisco's urban ecology and summarize economic processes into a sturdy modelĤ About the Model This model proposes that each realm is a separate economic, social, and political entity that is linked together to form the larger metropolitan framework.
