- urban development and its effects on social behavior
- Community influence
- Psychological and social influences
- Transportation and utility influences
- basic climate
- sustainability
Basic components of a Greek city.

Two key baroque city planners
Christopher Wren - London
George Eugene-Haussman Paris
Who conceptualized the Garden city?
Ebenezer Howard - 1898 (London). Reaction to the industrial Revolution
Who designed Central Park?
Fredrick Law Olmstead
What two architects from the 1920’s and 30’ thought of cities as wide open spaces
Corbusier and Frank Lloyd Wright
New Urbanism
Promotes the connection of neighborhoods and towns to regional patterns of pedestrian, bike, and public transit system to reduce car use.
Urban Sprawl
de-centralization of city center with large highways connecting shopping areas.
Five major types of development patterns
- grid
- star
- field
- satelite
- megaloplis
Star Pattern
Grows from a dense urban core with radiating spokes. Chicago is a half star pattern
Field Pattern
No central focus or overall organization scheme. Development takes place as an amorphous network or highways and natural features. Los Angeles is a key example
Imageability
The quality of a physical environment
The Image of the City
Book by Kevin Lynch identifies characteristics of the city.
- Path
- Edge
- District
- Node
- Landmark
Path
A path is a way of circulation along which people customarily, occasionally, or potentially move. A path may be a street, pedestrian walkway, railroad, transit line, or river. Paths are usually at the center of the image of a city.
Edge
A linear element that forms a boundary between two districts or that breaks continuity. Edges can be shorelines, buildings, walls, etc. The buildings around central park are an edge
District
A 2D area perceived as having some indentifying character that distinguishes it from the surrounding city. Back Bay (Boston) Geortown (Washington, DC).
Node
A focal point or center of interest that people can enter. A node can be an intersection of path, places where transportation changes, a plaza, or the center of a district.
Landmark
Similar to a node but can’t be entered.
Superblock
- An outgrowth of the New Town concept
- Concept is to minimize the impact of the car on housing and allow the development of pedestrian circulation and park space.
- Chandigarh, India (Le Corbusier) and Brasilia (Costa and Niemeyer)
Planned Unit Development
PUD. Similar to the concept of a superblock. Standards for PUDs include permitted uses, total FAR, amount of open space required, number and configuration of parking, living space ratio, max building heights, and required setbacks at the perimeter.
Transit-oriented development
Method of connection urban sprawls with each other and city centers.
Five Patterns of Urban Development
- grid
- star
- field
- satelite
- megalopolis
Proxemics
the interrelated observations and theories of man’s use of space as a specialized elaboration of culture. (Personal space and spacing + territoriality)
territoriatlity
A fundamental aspect of human behavior that refers to the need to lay claim to the space we occupy and the things we own.
Personalization
How people arrange the environment to reflect their presence.
What are the 4 major street types? (Smallest to Biggest)
Local Streets
Collector Streets
Arterial Streets
Expressways
Site Access Importance
Min 150’ from an intersection
Min 80 degree entrance
Avoid slight off set
Avoid two way y-intersections
What is the minimum distance between curves in opposite directions?
100’
What is the minimum distance between curves in the same direction?
200’
What is a straight portion of road called?
Tangent
For most streets what is the maximum grade range?
3 - 10%
