Analyse the City

Analyse the City.

The week 3 learning module included a number of tasks that were expected to further assist our understanding of urban spaces and help us to effectively analyse city. These tasks included various mapping exercises, many of which were very similar to those included in learning module 1, however, they were done on a slightly larger scale.

The task was done using Brisbane as the exemplar city. Brisbane is located in the South East of Queensland, and was settled along the Brisbane river, in the early 1820’s. The Brisbane river is a key element within the city and arguable shaped many areas of the inner city, due to its winding and meandering nature. Various analyses diagrams of the inner city are shown and explained below.

Exercise 1: Brisbane Timeline.

The following images represent the growth of Brisbane over time in a graphical manner. The darker the shape, the older that portion of the city is.

Graphical representation of Brisbane’s development over time.

The above image indicates that a large urban sprawl took place in Brisbane and the urban area developed outwards concentrically from the centre over time. The initial development  which is now the CBD, is the oldest area, while outer suburbs, may have been previously used as farms, have not been developed into urban spaces until the 1920’s.

This development is represented on a timeline below.

As the two images above indicate, Brisbane has developed immensely over time, and in a concentric manner, where the CBD is still the central point of the city. Development has stayed close to the river which reinforces its importance within the city.

Exercise 2: Mobility Analysis.

A mobility analysis is a key diagram that helps to determine how a city space is occupied and used. The mobility analyses highlights major roads, transport systems, public spaces and pedestrian paths within the urban environment and thus, it can be determined how specific areas of the urban landscape are used.

Roads- Yellow
Railway- Red
Citycat- Blue
Pedestrian walkways- Pink
Major bus hubs- Orange
Public squares- Blue
Green Spaces- Purple
Pedestrian Only Roads- Green

The diagram above simplifies the streets of Brisbane and highlights key elements within them. It indicates the abundance of public transport hubs within the CBD as well as a group of public squares. It also shows the Queen Street mall, and indicates that it is a pedestrian only space. There is also a variety of different public transport options within the city and along with the riverside walkway, this indicates that Brisbane is somewhat easy to navigate and pedestrian friendly city.

Green- High rise commercial
Purple- Mid rise commercial and residential
Dark blue- mid rise residential
Light blue- low rise residential

This diagram shows various zones within the CBD, and how the mobility analysis interacts with them. It indicates that there is a focus of public transport hubs in the high density spaces, while pedestrian paths and smaller roads are abundant in the ; less developed areas.

Exercise 3: Functional Analysis.

The functional analysis is similar to the diagram above, in that it highlights different land uses within the city. This makes it possible to understand how people use different spaces within the city and how the city as a whole functions.

Red- High rise residential
Orange- Mid-Low rise mixed use
Purple- School
Green- Green space
Blue- Low rise mixed use.

A s the above image indicates, there are a number of different uses of space within a small area of the CBD. Uses range from residential apartment buildings to commercial office buildings, low rise retail outlets and mid rise entertainment venues. Each type of space serves a different purpose within the city and they work together to help the city function effectively.

Exercise 4: Urban Morphology

The urban morphology of a space is somewhat similar to what is shown above, however, it reflects on the types of buildings within a space, rather than their uses. Various Urban Morphology diagrams of Brisbane are shown below.

Blue- high rise
purple- mid rise
light blue- low rise
pale blue- mid-low rise
orange- green space
yellow- transport hub

Through the diagram above it is possible to note the various building typologies within Brisbane. The image groups similar structures together and the varying size and density of each portion the image can be seen.

morpho3

Graphical Urban Morphology diagram

The above diagram is a graphical representation of the previous urban morphology diagram. This image simply shows the various grouping of spaces and disregards factors such as roads and other eements of the city. this makes it easier to read the layout of the city and determine the urban forms.

SUMMARY:

As a whole, the exercise was very useful, although some elements did seem a little repetitive and similar to those completed in week one. However, they definately did assist in helping my learning and progressing my understanding f a city environment. Hopefully i can use these tools effectively in project 2.
