example of boomburbs
Irvine, California
World cities
a major urban center that functions as a key hub for global, economic, cultural, and political activities

London and Tokyo
Worlds urban hierarchy
A ranking system of cities based on their global, economic, and cultural significance

London, Tokyo, and New York City are at the top
Rank size rule

Primate city

Paris, France
Gravity model
A concept that predicts the interaction between two places based on their population size and the distance separating them
Example of gravity model
Comparing the interaction between New York City and Los Angeles versus New York City and Mexico City
worlds urban hierarchy
categorizes cities into levels such as global cities, regional cities, and local towns based on their influence and functionality
christaller’s central place theory
explains the distribution of cities of different sizes across a region. The model used consumer behavior related to purchasing goods and services to explain the distribution of settlements.
burgess concentric-zone model
describes a city as a series of rings that surrounds a central business district; proposed in the 1920s
hoyt's sector model
a model that suggested that cities develop in sectors or wedges radiating out from the central business district (CBD) rather than in concentric circles; emphasizes that certain areas of a city are more likely to attract specific types of land use and socio-economic classes, influenced by factors such as transportation routes and social dynamics.
Harris and Ullman multiple-nuclei model
a model that suggested that functional zonation occurred around multiple centers, or nodes. The characteristics of each node either attracted or repelled certain types of activities. The result was a city that consisted of a patchwork of land uses, each with its own center, or nucleus.
Galactic City Model
the structure of urban areas that develop around a central city, characterized by the presence of peripheral suburbs and edge cities
Bid-Rent Theory
as one moves away from the central business district, the price of land decreases
Griffin Ford Model
a theoretical framework that explains the internal structure of cities, particularly in Latin America. This model highlights the spatial distribution of wealth and services within a city and how they interact with each other.
The McGee Model
describes the urban structure of certain Southeast Asian cities. This model highlights the lack of a strong central business district, instead presenting multiple nodes of activity, with a focus on the importance of the port and the presence of commercial and residential zones that develop around it.
Sub-Saharan African City Model
includes three CBDs: a colonial CBD: characterized by vertical development, including multi-story buildings. a traditional CBD: a zone of single-story buildings. a market CBD: an open-air, informal trading area.

example of infrastructure
transportation features, such as roads, bridges, parking lots, and signs and communications features such as cell phone towers, television cables, and Internet service
sustainable design initiatives
urban planning strategies aimed at creating environmentally friendly cities
example of sustainable design initiatives
reducing sprawl (uncontrolled urban expansion), promoting walkability, and increasing public transportation
zoning
legal process used by local governments to regulate land use and development within specific areas of a city
example of zoning
residential zoning (for homes), commercial zoning (for businesses), and industrial zoning (for factories).
mixed land use
the planning and development of urban spaces that integrate residential, commercial, and recreational areas within close proximity
example of mixed land use
a building where the ground floor is occupied by retail shops and restaurants, while the upper floors are used for residential apartments
walkability
the measure of how friendly an area is to walking
example of walkability
when neighborhoods are designed with pedestrian-friendly features like sidewalks, parks, and public spaces, people are more likely to walk and encounter others.
transportation-oriented development
helps reduce traffic congestion by encouraging people to use public transportation instead of personal vehicles
example of transportation-oriented development
We go buses in nashville
smart growth policies
encourage mixed-use developments where residential, commercial, and recreational spaces are integrated to reduce travel time and promote walkability
example of smart growth policies
promoting mixed-use development, walkable neighborhoods, and access to public transportation
New Urbanism
New Urbanism aims to reduce reliance on cars by promoting alternative transportation options like biking, walking, and public transit.
