Recommendations - City of West Torrens - SA.Gov.au

Major routes traversing the City include
South Road, Marion Road, Tapleys Hill
Road, Anzac Highway, Henley Beach
Road, Sir Donald Bradman Drive,
Richmond Road and Cross Road. These
roads are under the care and control of
the Department for Transport, Energy
and Infrastructure (DTEI).
The information on current congestion
levels in this network is sourced from
the Adelaide Urban Corridors Strategy
report 2006 (DTRS and DTEI), DTEI
major road projects and Adelaide
Airport Limited (AAL) Access Study
reports. Important parts of these
reports are reproduced in this section.
Level of Service (LOS) is an indicator of
road network performance based upon
traffic congestion criteria outlined in
the Austroads Capacity Guide to Traffic
Engineering Practice - Roadway Capacity.
LOS ranges from (A) – free flow
conditions to (F) where traffic demand
exceeds the capacity of the road and
serious congestion results.
DTEI’s general description of levels of
service in relation to volume/capacity
ratio is as follows.
LOS Degree of saturation
A-B 0 to 0.5
C 0.5 to 0.7
D 0.7 to 0.85
E 0.85 to 1.0
F Over 1.0
The degree of saturation is used to
identify intersection performances in
the following sections of the report.
FIGURE 2 shows the key intersections
and road corridors discussed in this
section of the report.

Part 1 - Overview | State of the DTEI Transport Network
‘ The number of trips made
during non-peak times is
growing faster than peak
travel and traffic congestion
is becoming more common
outside of the traditional
peak periods across the
entire road network.’
6.1 National Transport
Network and the Adelaide
Urban Corridors Strategy
National Transport Network is a major
Australian Government initiative
designed to improve planning, decisionmaking
and funding for the national
land transport infrastructure. A key
component of the National Transport
Network process is the development
of a strategy for each corridor of the
National Transport Network.
The Adelaide Urban Corridors Strategy
is based on the National Transport
Network objectives:
• Increase its infrastructure capacity and
efficiency.
• Improve its safety and security.
• Improve transport productivity on
its nationally strategic and exportoriented
freight corridors.
• Improve the reliability of travel on
interstate and inter-regional corridors.
• Are consistent with viable,
long-term economic and social
outcomes, and with obligation to
current and future generations to
sustain the environment.
The Adelaide Urban Corridors routes in
the City include:
• South Road, between Grand Junction
Road and Sir Donald Bradman Drive
- part of National Transport Network
corridor.
• Sir Donald Bradman Drive, between
South Road and Sir Richard Williams
Avenue (Adelaide Airport entrance)
- part of National Transport Network
corridor.
• South Road, between Sir Donald
Bradman Drive and the Southern
Expressway.
