Editing Multiple nuclei model (section)

==The Model==
The model describes the layout of a city, based on Chicago. It says that even though a city may have begun with a [[central business district]], or CBD, other smaller CBDs develop on the outskirts of the city near the more valuable housing areas to allow shorter commutes from the outskirts of the city. This creates nodes or nuclei in other parts of the city besides the CBD thus the name multiple nuclei model. Their aim was to produce a more realistic, if more complicated, model. Their main goals in this were to:
# Move away from the concentric zone model
# Better reflect the complex nature of urban areas, especially those of larger size

The model assumes that:
#Land is not flat in all areas
#There is even Distribution of Resources
#There is even Distribution of people in Residential areas
#There is even Transportation Costs<ref name="Human Geography">Swanson, Kelly. Kaplan AP Human Geography. 2009. 2009. 360-364.</ref>
