The Inner Sydney Transport Challenge
Sydney is Australia's global city. At its core
lie the City of Sydney and the inner suburbs. This area has
the nation's highest concentration of jobs, population and
tourist attractions. It is estimated that the City of
Sydney alone generates economic activity of $60 billion
annually, 8% of the nation's GDP.
Sydney is also Australia's oldest city. Originally built around an extensive tramway
and railway network, many of its inner areas were never
designed for the car. While its narrow streets and
harbour-side setting add to its charm, they also create
traffic bottlenecks.
Sydney is also a fast growing city. In
the 1990s the City of Sydney added 60,000 jobs, and had
the highest population growth rate of any local government
area.
The inner suburbs are also growing strongly with the
rise of apartment living. International visitors, almost
half of whom arrive in Sydney, doubled during the 90s, and
the City has three-quarters of all hotel accommodation in
the Sydney region.
As a result, the city's transport
systems are at capacity. Despite addition of new roads such
as the Eastern Distributor, traffic on remaining roads in
the inner suburbs grew by 20% in the 1990s. Bus and rail
patronage also rose strongly in the last decade, and there
are now 7,400 State Transit bus movements, plus growing
numbers of private buses and tourist coaches, traversing
the CBD daily. Despite the addition of bus lanes, buses
typically average less than 10 kph in the city centre.
Hundreds of buses travel slowly nose to tail in long queues
between Central and Circular Quay every morning and
evening. Space for buses to layover between runs is at a
premium, with significant congestion in several streets
used for bus layovers.
These transport and traffic problems
will get worse. Both population and employment in inner
Sydney are expected to grow by 20% by 2021, more if there
is intensified development along Parramatta Road and in the
southern corridor to the airport. The demand for travel
within the CBD is estimated to rise by 32% by 2021, while
the demand for travel to and from the CBD will rise by 22%.
Longer term, the medium migration forecasts suggest Sydney
as a whole will grow by 44% to 5.9 million by mid-century.
At the same time, there is rising concern at the
environmental and health impacts of transport. Mobile
sources account for 80% of Sydney's emissions of nitrogen
oxides, almost 50% of volatile organic compounds, and 20%
of particulates. Diesel-powered vehicles are a major source
of particulates and NOx, as well air toxics, such as
toluene and benzene.
Walking has been in decline in Sydney
for some time, whilst cycling plays a very minor role for
most people. Growing obesity levels and their health
effects are one side effect of the lack of regular exercise
by large numbers of people. Cars are a major cause of this
whereas half of all walking trips are part of a public
transport journey, cars tend to substitute for walking. In
addition the growing volume of traffic makes cycling all
but impossible except for the few cycle paths available in
the inner suburbs.
Continuing to rely on current surface
transit options, in particular on cars and buses, will
become increasingly inefficient and unworkable. This will
erode the amenity of the city and undermine its economic
potential.
| Inner Sydney needs a world-class transport
system if Sydney is to remain a world-class city.

Goals and Objectives of the Strategy
A new integrated transport strategy is needed to
achieve a world class transport system. Key goals for this
strategy are to:
- Enhance Sydney's role as Australia's
economic powerhouse
- Cater for future growth in travel
demand whilst minimising the adverse congestion,
environmental and health impacts of travel
- Increase the
share of trips by walking, cycling and public transport and
to reduce the share by car
- Improve the efficiency and
appeal of the public transport system for inner Sydney and
the CBD.
Specific objectives to achieve these goals are:
- To improve footpaths and increase the amount of
pedestrianised streets in the city centre
- To provide a
set of safe cycling routes throughout the inner suburbs and
the CBD, enabling cyclists to access regional cycleway
networks and major activity generators such as
universities, employment and retail centres and major
recreational facilities.
- To increase the capacity of the
on-street public transport system linking the inner suburbs
to the CBD by at least 35% by 2021 and 60% by 2051
- To reduce the number of buses entering the CBD daily by at
least a third, and to reduce the number of buses travelling
on key north-south routes through the CBD by at least 50%
by 2021, compared with a business as usual scenario.
- To improve cross-regional public transport services throughout
the inner suburbs, to allow more local car trips to be
taken by public transport
- To encourage travel demand
management measures to reduce the need for inner suburban
residents to own and use private cars.
Key Elements
Key elements of a strategy to tackle these objectives include:
- Developing a new mass transit network in the CBD and on
key corridors linking the city with the inner suburbs.
Potential corridors include:
- CBD to Maroubra Junction via UNSW
- CBD to Burwood via Lillyfield
- CBD to Mascot via Green Square
- CBD to Burwood via Parramatta Road
- CBD to Bondi via Bondi Junction.
- Re-organising bus routes to act
as feeders, and to increase the number of cross-regional
bus services.
! Improving the integration of all modes
through high quality interchanges, integrated ticketing and
fares and real-time information.
- Limiting parking levels
in the CBD in commercial parking stations at current levels
and providing incentives for developers to minimise the
amount of parking provided for new development generally in
the city.
- Providing additional park and ride
opportunities at strategic locations in the inner suburbs,
especially on light rail routes, to encourage current car
drivers to make at least part of their journeys on public
rather than driving right into the city centre.
- Providing
wider footpaths and cycle lanes in city streets and other
locations in conjunction with the establishment of the
light rail system.
- Adding at least one kilometre of fully
pedestrianised streets to the city centre by 2021.
- Supporting the development of carsharing, individual travel
marketing schemes and travel demand management strategies.
Routes and Staging
The five proposed mass transit corridors
were developed by analysing current patronage volumes, ease
of implementation, future growth potential and the
existence of competing heavy rail systems. Within the CBD,
three potential alignments have been identified: George
Street (2- way); Castlereagh Street (2-way); and Pitt and
Castlereagh (Figure 8). Eventually both the George Street
route and one of the other two routes will be needed for
capacity reasons. The formal choice of routes and the
staging of construction are subject to discussion with
State and Local Governments and other key stake-holders and
further analysis of traffic and other issues.
Benefits from the Strategy
The proposed strategy will:
- Reduce buses
coming into the city by 36%, reduce the number of buses in
north-bound streets by 54% compared with a business as
usual situation, and reduce the pressure on the heavy rail
system.
- Increase capacity of the inner Sydney public
transport network to enable it to cater for growth and a
shift from cars
- Improve amenity and maintain Sydney's
world city status, supporting the economic growth of the
entire Sydney region
- Facilitate walking and cycling in
the City and Inner Suburbs
Rationale for Mode Choice
Continuing to rely on
the current bus based system into the future is not
considered sustainable or desirable:
- Buses are already a
major source of noise and emissions in the city centre
- The anticipated growth in demand would mean over 9,400
State Transit buses alone driving through the city centre
on weekdays by 2021
- Bus congestion is already bad. The
system is inefficient despite the use of bus lanes, and
will worsen with more buses and traffic
- Buses operating
in mixed traffic are slow and unreliable and not likely to
attract customers out of their cars.
- Continuing with the "Business as Usual" approach of trying
to squeeze more buses
into the city centre will result in potential loss of
economic activity to Sydney, which competes with other
world cities on the basis of its quality of life.
Options for improving the quality and capacity of mass transit in
the CBD and inner suburbs include:
- Articulated buses and guided buses
- Light Rail
- Underground metro rail
- Various forms of above ground automated systems.
These alternatives have been evaluated in various studies. For
example:
- Walsh and Associates (2002) found that light
rail was the preferred mode, scoring highest on the
criteria of capacity, external impacts, and service
quality, and overall.
- Parsons Brinkerhoff (2004b)
compared continuing with current buses, introducing high
capacity buses and light rail. Light Rail was found to be
the best or equal best option in 11 of the 12 criteria used.
- Studies by the Department of Infrastructure,
Planning and Natural Resources found metro rail, followed
by light rail, to be the preferred modes for five key
corridors from the inner suburbs to the CBD. However only
the northern corridor requires metro rail capacity.
Overseas experience clearly backs light rail as the
preferred mode for these types of applications:
- In the last decade, over 100 cities world wide have built new
light rail systems or expanded their existing systems. By
contrast, only around ten cities have adopted guided bus
technologies.
- Light rail vehicles have higher capacity
than guided buses, and hence lower operating costs.
- The UITP committee on Light Rail and Guided buses found little
difference in capital cost between the modes if
electrification and full priority is to be provided. These
characteristics are essential to a high quality, high
capacity system for inner Sydney.
- Guided bus systems are
still under development, with technical problems being
experienced by some systems. The different guidance systems
are also incompatible, meaning that a city adopting one
system will be limited to a single manufacturer to supply
future vehicles.
Light Rail has therefore been identified
as the key element of the strategy to boost the capacity
and quality of the mass transit system for the inner
suburbs and CBD:
- It is the most appropriate mode given
the nature of the transport task and the environmental and
other conditions in the area
- It is affordable and cost-effective
- It is backed by experience elsewhere
- It is designed to be completed in a fifteen year timeframe.
