CITY SCALE ANALYSIS 2 2
Every weekday in metropolitan Sydney people make around
seven million journeys that are shorter than two kilometres. More than three million of these short trips are walk only trips and a further three million are travelled by car. Many short car trips could be replaced with walking trips. - nsw government

LOW LEVEL OF EVENING TRAFFIC
The gereral walking pattern shows that the highest concentrations of Most of the pedestrian traffic is limited to Pitt Street retail Mall and As compared to daytime traffic, sydney fares poorly during the evening. pedestrians are to be found in the retail core of Pitt’s street Mall, George George Street and fails to connect through the spine of George Street A majority of the shops close down between 8 - 9pm and a bulk of the Street (between Market and King street), Martin Place, southern part to the Rocks and Circular Quay.2 population exits the City Centre.3 of George street and Brodway near Central Station. The Northern end of George Street along with Circular Quay and the pedestrain plaza which connects to the Sydney Opera House are the most pedestrian populated areas in the CBD.1

LACK OF TRANFER OF PEDESTRIAN TRAFFIC THROUGH PUBLIC PRECINCTS Pedestrian traffic in the CBD is concentrated at retail zones such as Pitt Street retail mall. However, this traffic fails to make its way through to Circular Quay and the harbour along this North - South dominanat axis. Concentration of pedestration movement diminishing towards circular quay due to the lack of active street frontages can be seen in the diagram (right).

INTRICATE NETWORK OF UNDERGROUND WALKWAYS
GETTING ACROSS
The city can be traversed underground, or at least without confronting vehicles, all the way from south of Bathurst Street to Chifley Square and mid-Macquarie Street. If the authorities cared to excavate a link from Chifley Square to Pitt Street, just two blocks away, the network would reach northern York Street. An extension further west to Clarence and Kent Streets and Barangaroo South is already in the pipeline. With another short addition from Jamieson Street, it could get to Circular Quay.4
The functional grid of the city has been aligned along the North-South axis. In Sydney, the focus has been on vehicular traffic and ways of facilitating car movements so that the pedestrians have gradually become a category of secondary city users who face many hardships and experience both great difficulties and real danger whern choosing to walk in the city.5

Inorder to evaluate the walking quality offered, 6 test walks were carried out. In each case ordinary walking speed was maintained and the walking time as well as the waiting time at traffic intersections was recorded. the conclusion of the tests is that waiting time at crossings is a substantial problem in Sydney. The test walks show a general delay of 30-50% in th east-west streets and about 20% in the north-south streets. A similar survey carried out in Adelaide 2002 showed an average delay of about 16%.7

Push buttons have been installed all over Australia, In order to cross a street, after pressing this digital device, it will give you about 7 to 10 seconds beforethe lights starts to blink red to tell you to finish walking across the road. Red periods are often long lasting between 60 and 90 seconds. On a busy city street, this leads to accumulation of about 30-40 people at the crossings which interferes with the footpath pedestrian circulation.6

An intricate network of underground walkways suggests that inorder to have a signal free walk, you have to use the underground level as opposed to the street level. Disconnecting with the ground plane compromises on the quality of the walk. The city has been baised towards vehicular traffic and this needs to change.

MISSING LINKS IN THE PEDESTRIAN NETWORK
DAWES POINT PARK
Although, Sydney has a fair amount of green space in the City Centre (74,000 m2) there tends to be weak connections in between them. The existing open spaces are scattered across the city and although they cover most of the City Centre they do not constitute a connected network for users to enjoy. The most important spaces are Martin Place, Pitt Street Mall, Sydney Square and Circular Quay. These make up the spine of Sydney’s open spaces. Still all of them have their limitations; Martin Place consists of 5 individual parts interrupted by vehicular traffic, Pitt Street Mall is only a 200 metre stretch, Sydney Square is a limited sized space and is partly sunken, while Circular Quay has an outstanding setting, it suffers from weak connections to the city due to the Cahill Expressway.8

‘Circular Quay is the only transit interchange in Sydney which connects all modes of transport at one location’
Circular Quay has been extensively used as an important node of the Sydney transit chain across history right from 1916 when steam trams ran across Alfred street to the 2019 vision when light rail will be introduced to match the demand for an efficient public transit system. 1916

(The following data analysis was carried out by Jahn Gehl Architects on a summer weekend (Saturday) in March 2007 on an hourly basis)
The Sydney CBD work force arrive at Circular Quay via the ferries and the train station. They tend to follow a North- South path to commute to the commercial core of the city. The tourists and the elderly who use circular quay for leisure activities tend to move more along the EastWest corridor (The Rocks, Customs House, Sydney Opera House, Royal Botanical gardens). This friction of cross pedestrian movements leads to chaos.
17 17
INCREASED PRESSURE ON WEEKENDS Circular Quay is used throughout the day, every month of every year by people of all generations. People visit to play, work and commute. Due to the inreased demand on weekends which witnesses a 65% increase in pedestrian flow as compared to weekdays, there is a need to distinguish the transit and social promenade. A need for an alternate ground plane is necessary.
There is a need to segregate transit and leisure

Cahill Expressway - Sydney’s eyesore ‘how the harbour looks from the city’

“The expressway’s location reveals the all-hail dominance of mobility in mid- century Sydney, its design avoids any hint of the dynamic, ditching the urgent aesthetic of the moment for dull municipal togs that belie its function as well as its moment in history”- Elizabeth Farrelly,2002
Former prime minister Paul Keating raised a proposal to demolish the Cahill Expressway

“Removal of the expressway would reconnect the city with the harbour and strike the right balance between open space, public space and commercial space,”- Graham Jahn, The Director of City Planning, Development and Transport for the City of Sydney, If the Cahill Expressway and the monumental granite architectural centrepiece were removed and replaced with minimal glazed canopies over the platforms, the public realm and station would be given a new life and the city would better engage with the harbour”- Philip Thalis, Public Sydney

RETAIN & GREEN IT
The Cahill expressway blocks the city from the harbour.
Alfred street is surrounded by transit which creates noise pollution and degrades the ambience for pleasure walks.
Cahill Expressway creates a rift between First Fleet park and the Royal Botanical Gardens. There is an entrance at the botanical garden end but none near the fleet park.
It acts as a barrier in a cultural rich environment breaching visual connectivity between the Customs House, MCA and the Sydney Opra House.
Greening the Cahill expressway can breathe new life into a public spaces dominated by vehicular mobility for decades.
LEISURE ON TOP; TRANSIT AT THE BOTTOM The green walkway will restore activities at Alfred street without the transit chaos

dire need for vertical greenery

IMPROVE RELATIONSHIP BETWEEN HIGH RISES AND THE GROUND PLANE Sydney’CBD is on its way for a vertical sprawl with the current height restrictions being uplifted to 310m. In this race of building tall, we often compromise on the green cover necesssary to sustain a community and healthy life. It is important for each individual to be in the vicinity of quality green spaces. Vertical greenery is the need of the hour
NETWORK OF COMMUNITY SPACES A number of public plazas and streets are uniformly spread across the CBD. However they fail to be in the vicinity of green spaces and public parks. Barring Circular Quay and the Australian Museum, none of the public streets and spaces aling within a walking radius of 200m from the public parks.

Circular Quay is the amalgamation of all transit options in the city. The site would benefit from opening up the ground plane. Retail and restaurants would further enhance the economic returns.
The site has views to the Sydney Opera House and the Harbour bridge even from the ground plane. Some adjacent sites such as AMP Precinct lack this opportunity has its views below 40M are blocked by
The APDG precinct presents with the opportunity to connect First Fleet Park to the site. This results in greenery being connected along both, north - south (Fleet Park and Royal Botanical Gardens) and east - west (Fleet Park and the site).
The site sits between Pitt street and George street. Both these streets have active street frontages to encourage pedestrian mobility which benefits the site.

a linear museum The site is surrounded by historic and cultural monuments. Cahill walkway will embrace the idea of a linear museum with each section telling a story of the site adjacent to it, for example : the section opposite the Rocks will date back to the time when convict settlements were established and gradually take the visitor through time to its present day form and fabric. Further it can point out directly to certain spots such as Gallows Hill (the hill where people gathered to watch hangings) where Essex Street stands today. The Museum will paint a picture over time and accustom visitors to Sydney’s foundation.
