Urban planning theories have evolved over time in response to changes in populations, economies, and technologies. Early theories focused on orderly city layouts with separate zones. Hippodamus proposed dividing cities into public and private areas with grids. Howard's Garden Cities aimed to blend urban and rural advantages. Geddes emphasized relationships between people and environments. Later, modernist planners like Le Corbusier proposed high-density "Radiant Cities." Burgess' concentric zone model depicted socio-economic groups arranged in circles. Perry's neighborhood unit promoted walkable communities. Today, multiple nuclei and sector theories recognize dispersed growth around transportation networks.

2. The design and regulation of the uses of space that
focus on the physical form, economic functions, and
social impacts of the urban environment and on the
location of different activities within. This involves
goal setting, data collection and analysis,
forecasting, design, strategic thinking, and public
consultation.
Three actors have main role in urban planning
• The decision-makers
• The technicians
Urban planning

3. • Spatial is relating to space
• Urbanization is the movement of population from
rural to urban areas
• A theory is an organized system of accepted
knowledge that applies in a variety of circumstances
to explain a specific set of phenomena.
• Urbanization is a relatively new global issue.
• In 1950 only 30% of the world’s population was
urbanized and 50% in 2009 lived in urban centres
• The big question is how do towns come about to be?
Introduction to Urban Planning

4. • The first recorded description of urban planning is
described in the Epic of Gilgamesh,
• Designed cities were characteristic of the Minoan,
Mesopotamian, Harrapan, and Egyptian civilizations
of the ancient period.
• Aristotle says- “Hippodamus invented the vision of
cities”. Therefore he was called the father of Urban
planning in the 5th century BC.
• Ideal cities centrally planned in the 15th century.
• In 1876 the term urbanisation posed by Ildefons
Cerdà due to the re construction processes
History of Urban Planning

5. The city of Priene
• Proposed by Hippodamus of Miletus who is considered
the father of rational city planning
• The center of the city contains the agora (Market place),
theaters, and temples.
• Private rooms surround the city’s public arenas.
• The plan can be laid out uniformly over any kind of
terrain since it’s based on angles and measurements.
Grid model/Hippodamian plan

7. • Planning and architecture went through a paradigm
shift at the turn of the 20th century.
• The industrialised cities of the 19th century had
grown at a tremendous rate, with the pace and style
of building largely dictated by private business
concerns.
• The evils of urban life for the working poor were
becoming increasingly evident as a matter for
public concern.
Modern Urban Planning

8. • Planning theorist- Paul Knox argues that the
profession of planning emerges out of a series of
crisis and people’s responses to them
• health crisis (epidemics)
• social crisis (riots, strikes)
• other crisis (fire, flood, etc.)
Urban planning is a response to these crisis or
problems
Modern Urban Planning

9. Modern Urban Planning
• Physician Benjamin Ward Richardson wrote Hygeia,
City of Health (1876) envisioning:
• air pollution control
• water purification
• sewage handling
• public health inspectors
• replacement of the gutter with the park as the site of
children’s play
• Such concerns motivated the Parks Movement.
• Naturalistic parks were created in the U.S. by Frederick
Law Olmstead, Central Park being the Ist, New York, 1857.

10. Modern Urban Planning Theories
• 1883 Linear City- Don Asturo Soria Y Mata
• 1902 Garden Cities - Sir Ebenezer Howard
• 1909 Region City- Sir Patrick Geddes
• 1922 Radiant city- Le Corbusier
• 1925 Concentric Zone theory- Sociologist Ernest Burgess
• 1929 The Neighbourhood Unit theory- Clarence Perry
• 1929 Radburn City- Clarence Stein & Henry Wright
• 1933 Central place Theory- Walter Christaller
• 1934 Broad Acre city- Frank Lloyd Wright
• 1932 Sector Theory- Economist Homer Hoyt
• 1945 Multiple Nuclei - C.D Harris &Edward L Ullman

11. The Linear City
• A town for 30,000 people based upon the principal
transport route which is 100 meter wide of infinite
length depending upon urban growth.
• All services channeled along the street
• Other community facilities group at regular intervals
• Residential area is limited to 200 meter either side
beyond which would lie the Countryside.
• The linear city gears away from the usual centric
urban forms. The lines help control the expansion of
a city.

The Linear City

13. • Addressed population and pollution that came about by
the industrial revolution by creating garden cities.
• Created by Ebenezer Howard in 1898 to solve urban and
rural problems
• “Garden City”, most potent planning model in Western
urban planning
• Source of many key planning ideas during 20th century.
• Welwyn and Letchworth are the cities designed for 40,000
and 35000 people respectively.
• Influenced the later strategy of building new towns in the
UK, US, Canada, Argentina, Israel and Germany.
Garden city– Sir Ebenezer Howard

14. Garden City
A great deal of criticism has been
levelled at Howard’s plans as being
unrealistic in their adherence to
geometric proportion, but he
presented his design of concentric
circles of varying land use as a
universal rather than as a particular
mode.
Sir Ebenezer Howard’s Three Magnets

15. • The possibility that the best
of urban and rural could be
incorporated on “Garden
City”.
• Inspired by the idea of ideal/
Utopian cities.
• Was intended to bring
together the economic and
cultural advantages of city
and country life while at the
same time discouraging
metropolitan sprawl and
industrial centralisation.
Garden city– Sir Ebenezer Howard

16. • As with most instances of
social engineering, it
didn’t quite achieve what
it set out to do.
• an ideal, self-contained
community of pre
determined area &
population surrounded by
a greenbelt.
• Land ownership would be
vested in the community
(socialist element)
Garden city– Sir Ebenezer Howard

19. • Introduced the notion of a region
• Called the Father of Modern Town Planning.
• Biologist,sociologist,and geographer.
• Wrote the book Cities in Evolution.
• Dissected the planning environment by analysing
occupational activities.
• Used observation and the rational planning method
of Survey Analysis
The Region City- Sir Patrick Geddes

20. • Introduced the term conurbation, which means “an
aggregation of continuous network of urban communities.
The Region City- Sir Patrick Geddes

21. •Patrick Geddes explained an organism’s relationship
to its environment as follows:
•This can be understood as a place acting through
climatic and geographic processes upon people and
thus shaping them.
•At the same time people act, through economic
processes such as farming and construction, on a
place and thus shape it.
•Thus both place and folk are linked and through
work are in constant transition.
• Emphasised the relationships of people & cities, thus
the city- region term.

22. The Region City- Sir Patrick Geddes

23. Radiant City,
● Le Corbusier: Founding father of the modernist
movement.
● Had a very high density:
● 1,200 people per acre in skyscrapers
● overcrowded sectors of Paris & London ranged from
169-213 pers./acre at the time.
● 120 people per acre in luxury houses
● 6 to 10 times denser than current luxury housing in
the U.S
● Multi-level traffic system to manage the intensity of
traffic

25. Also known as The Bull's Eye Model
• The concentric zone model, also known as the Burgess
model or the CCD model, is one of the earliest
theoretical models to explain urban social structures.
• It was created by sociologist Ernest Burgess in 1925.
• The model portrays how cities social groups are
spatially arranged in a series of rings.
• The size of the rings may vary, but the order always
remains the same.
Concentric Zone Theory

26. Concentric Zone Theory

27. 1. Central Business District (CBD) - This area of the
city is a non-residential area and it’s where businesses
are. This area s called downtown ,a lot of sky scrapers
houses government institutions, businesses, stadiums,
and restaurants
2. Zone of Transition- the zone of transition contains
industry and has poorer-quality housing
available.Created by subdividing larger houses into
apartments
Concentric Zone Theory

28. 3. Zone of the working class- This area contains modest
older houses occupied by stable, working class families. A
large percentage of the people in this area rent.
4. Zone of better residence- This zone contains newer and
more spacious houses. Mostly families in the middle-class
live in this zone.
5.Commuter’s Zone/Suburbs- This area is located beyond
the build-up area of the city. Mostly upper class residents
live in this area.
Concentric Zone Theory

29. IV – working class area
V – residential area
VI – suburban area
I - Loop (downtown; CBD)
II – industries
III – transition area

30. Neighbourhood unit theory
CLARENCE PERRY
1872-1944
• Conceptualized the
neighborhood unit
• Similar to the
superblock
• Bounded by major
streets
• Has a church, school,
and shops
• 200 sqm to 2 sqkm
Wikipedia
• Clarence Perry
conceptualised the
neighbourhood unit
• Similar to the super block
bounded by major streets
• Has a church,school, and
shops
• 200 sqm to 2 sqkm.

31. ●The objectives were:
●To make the people socialize with one and
another.
●To enable the inhabitants to share the public
amenities and recreational facilities.
●To support a safe and healthy environment
within the neighborhood.
●To provide safety and efficiency to road users
and pedestrians.
●To maintain, enhance, and improve area for
Neighbourhood unit theory

32. • Size of neighborhood unit related to the
catchment area of a primary school.
• No through traffic- residential area bounded on
all sides by arterial roads
• Ample parks and play areas
• A neighborhood center containing school, local
center and other services
• A hierarchy of roads/ streets (to promote road
safety, pedestrian safety, conserve residential
environment)
Neighbourhood Design Principles

33. Neighbourhood Design Principles

34. Radburn Superblock
• A town for the motor age.
• Encourage pedestrian accessibility.
• Low traffic volume in the neighborhood
• Open space linked the residential areas.
• Houses built around cul-de-sac which are connected
to open space
• Houses are segregated from main roads
• Pedestrian paths and walkways linked the houses to
primary school and local centre

35. Radburn Superblock, New Jersey

• Mechanical means to be
planned for
• Facilitate Human life &
civilization.

38. • Examples. Polders of the Netherlands, the Fens of East
Anglia in the UK
• Developed by the German geographer Walter Christaller in
1933
• It explains the reasons behind the distribution patterns,
size, and number of cities and towns.
• Tested in Southern Germany and came to the conclusion
that people gather together in cities to share goods and
ideas.
Central Place Theory

39. Assumptions
• humans will always purchase goods from the
closest place
• unbounded all flat, homogeneous, limitless surface
• evenly distributed population
• all settlements are equidistant and exist in a
triangular lattice pattern
• evenly distributed resources
Central place theory

40. Central place theory

41. Broadacre City Theory
• low-density
• car-oriented
• freeways +feeder
roads
• multi nucleated

42. Broadacre City Theory
• Champion and proponent of urban
decentralisation
• Involved communities
• Designed the 1000-hectare Broadacre City
• Included social services in the forms of
schools,trains, and museums, as well as
employment in the forms of markets, offices,
nearby farms, and industrial areas.

43. Chicago and Newcastle upon Tyne/Newcastle
• Developed in 1939 by land economist Homer Hoyt
• It is a model of the internal structure of cities.
• Social groups are arranged around a series of
sectors, or wedges radiating out from the central
business district (CBD) and centred on major
transportation lines
• low-income households to be near railroad lines,
and commercial establishments to be along
business thoroughfares
Sector Theory

44. Stresses the importance of transportation corridors.
Sees growth of various urban activities as expanding
along roads, rivers, or train routes.

46. Shortcomings
• Applies well to some towns only
• Low cost housing is near industry and
transportation proving Hoyt’s model
• Theory based on 20th century and does not take
into account cars which make commerce easier
• With cars, people can live anywhere and further
from the city
Sector Theory

47. • The Multiple Nuclei Model is an ecological model
created by Chauncy Harris and Edward Ullman in the
1945
• City grows from several independent points rather
than from one central business district.
• As these expand, they merge to form a single urban
area.
• Ports, universities, airports and parks also act as nodes
• Based on the idea that people have greater movement
due to increased car ownership.
Multiple Nuclei Theory

48. Multiple Nuclei Cities: Harris-Ullman

49. • The model has four geographic principles
• Certain activities require highly specialised facilities.
• Accessible transportation for a factor
• Large areas of open land for a housing transition
• Certain activities cluster because they profit from
mutual association
• Certain activities repel each other and will not be
found in the same area.
• Certain activities could not make a profit if they paid
the high rent of the most desirable locations
Multiple Nuclei Theory

50. Stresses the importance of multiple nodes of activity,
not a single CBD. Ports, airports, universities attract
certain uses while repelling others.
Multiple Nuclei Cities: Harris-Ullman

51. Assumptions
• Land is Flat
• Even Distribution of
Resources
• Even Distribution of
people in Residential
areas
• Even Transportation
Costs
Multiple Nuclei Theory
Criticisms
• Each zone displays a
significant degree of internal
heterogeneity
• and not homogeneity
• No consideration of influence
of physical relief and
government policy.
• Not applicable to oriental cities
with different cultural,
economic and political
backgrounds
