street design

2. “Are the connectionsbetween spaces and
places “Originally the word "street"
simply meant “a paved road”

3. What’s the difference between
a road and a street?

4. The road aims to provide “transportation”.
Transferring passengers from place to another
The road:
Examples of roads:
High ways.

5. Aims to facilitate public interaction.
The Street:
Pedestrian streets, alleys, retail streets …...
Examples of Streets:

6. Defining a street as a road for vehicles is not the same as designing it
as a ‘path’.
• has both a beginning and an end, definite places or
nodes with special use and activity along its length.
• such paths present to the observer a memorable image
of connected places.

7. Designing the street as a path:

start “library”
Important building
at the end
Specific points with special
usesalong the path

8. The streets
• The street is more than a simple
pathway
• It represents a series of
connected places, for staying in
and not just for moving through.

9. A paved public thoroughfare in a built environment. It is a public
parcel of land adjoining buildings in an urban context, on which
people may freely assemble, interact, and move about.

10. The type of streets

11. Alley is:
A narrow passage or way in a
city between or behind
buildings
Alleys are narrow, without
sidewalks.

13. The walkway :
• The walkway is a path for walking
• It can be at ground level, or it can be
elevated.
• It can cross a road or a water body.

15. A sidewalk is:
• A path for pedestrians that is
located alongside a road .

16. A sidewalk:
sidewalksidewalk

17. • Sometimes, there is an area called a parkway or tree
lawn in between the sidewalk and the road.
A sidewalk :

18. A sidewalk:
The sidewalk can be divided into zones

19. An avenue is:
• A straight street with a line
of tress along each side.
• In most cases, the trees
planted in an avenue are of
the same type, so as to
uniform appearance of the
avenue.

21. Main Street is:
• primary retail street in a
village, town, or small city.
• It is usually a focal point for
shops in the central business
district .
In some larger cities, there may be several Main Streets.

23. Boulevard :
• A boulevard is usually a wide,
multi-lane arterial thoroughfare
• divided with a median down the
center.
• has roadways along each side and
parking lanes and bicycle lanes
and pedestrian sidewalks, with
landscaping.

25. A cul-de-sac :
A dead end or closed street, only one inlet/outlet, its function is to
calm vehicle traffic.

26. A cul-de-sac :
Usually used in residential areas.

27. A highway is:
A main road for traveling between
important destinations, such as
cities, large towns, and states.
The design of the highway varies
it can be a two-lane road or multi-
lane depending upon the volume
of traffic.

29. The form of the street

30. THE FORM OF THE STREET
The form of the street can be analyzed in
many ways such as:
Street pattern:
Grid – organic- irregular…..
Street length:
long or short.
Street proportion:
The ratio between the width of the street
and the height of the buildings along the
street.

31. THE FORM OF THE STREET
The irregular and organic patterns are more interesting for people
because they give them the sense of discovery.
Although the uniform grids are easier for traffic.
Street pattern:
uniform grids Radial grids Irregularpattern organic

32. Street length:
The upper limit for continuous
length of street is 1,500 m (1
mile).
Beyond this distance human
scale is lost.
THE FORM OF THE STREET

33. • For long distances the prominent building will lose its dominance and
begin to merge into the surroundings.

THE FORM OF THE STREET

34. • The ratio of width of street to
height of enclosing buildings is
important for street design.
• for example, when a street is
long and wide with two-storey
houses along its sides the sense
of space enclosure is lost.
Street proportion:
THE FORM OF THE STREET

35. • The ratio of height to width of 1: 1 is
not too tight for comfort
• If the height exceeds the width it will
create a sense of fear.

36. 2.5
1
• The ratio of height to width 1:
2.5 creates a weak sense of
enclosure
• If the width is more than 2.5 the
height the sense of enclosure
will be lost.

37. The wide street is favored
by the road engineers to
facilitate traffic movement.
But narrow streets with
continuous enclosing building
slightly higher than street
width facilitate shopping,
movement from side to side
and are considered as
attractive places.
Street proportion:
THE FORM OF THE STREET

39. • If the street locates in a cold
area it should be wide to
capture sun light.
• And if the street locates in a
hot country it should be
narrow with high buildings to
provide shading and temper
the heat of the site.

40. The unity of street design

41. UNITY IN STREET DESIGN
• The most important factor in
creating the unity of streets is
the form of buildings located
along the streets.
• When the buildings along the
street have varied forms,
styles and treatment the space
loses definition.
Unity means the sense of
continuity and harmony.

42. • Clearly, the use of common
materials, details and architectural
elements strengthen the unity of
street.
• Also the use of a common roofline.
• The roofline establishes the lid for
the space and if there are great
variation in its height the space
becomes unstable

43. UNITY IN STREET DESIGN
What makes the unity of
street design difficult is
the varied needs of the
owners of the buildings
and the difference taste
of each one.
But creating specific
regulations tailored for
each area with
participation of users can
help solving this
problem.
