Local Road Network
Movement function predominate
for such roads, with clearways
sometimes provided to satisfy capacity
requirements.
In recent years, functional classification
of roads have been used. For example,
DTEI’s functional classification
describes the predominant use of a
particular road:
• strategic routes (all modes)
• freight routes
• car (commuter) access routes
• tourist routes
• passenger transport routes
• pedestrian zones
• cycling routes
The issue of road classification was
considered in the Metropolitan Local
Government Transport Strategy.
The Strategy notes that it would
be desirable to have a uniform system
in the metropolitan area and this
is supported.
Without being overly prescriptive,
it is desirable to have a uniform
system for classifying roads throughout
the metropolitan region.
Accordingly, the following threetiered
classification model is offered
for consideration:
• road hierarchy (i.e. to determine
road responsibility)
• road functionality (i.e. to identify
how a road should operate)
• road land use relationship.
The value of this approach is that the
transport and access/land use role of
each road can be better described,
which can lead to development of
clearer road performance criteria.
The interrelationship between the
road environment and adjacent land
uses can also be better understood,
along with the compromises that
are often needed in managing the
available road space.
MLGTS study August 2005
The SA Grants Commission has also
used the functionality of a road (a
three-tier classification of freight,
tourism and social) as part of its Special
Local Roads funding considerations.
The MLGTS has proposed the following
functional hierarchy description:
Freight route - Facilitates industry
development by linking key industries
to major transport routes and
contributes to efficient movement of
large volumes of heavy freight vehicles.
Primary Freight Routes link strategically
important economic regions within and
external to the State. Secondary Freight
Routes link urban and regional freight
generators and providing connections
to primary freight routes –
See Figure 10.
Social access routes - Provides for
community development and equitable
access to community facilities whilst
minimising the impact of heavy
vehicles on the community. Routes that
provide a high level of connectivity
between areas (through routes),
including those that supplement the
arterial road network, or that provide
immediate access to community spaces
or recognised shopping precincts.
See Figure 11.
Tourist routes - provides access to
tourism sites and locations and enables
people to view scenic attractions in
a safe and enjoyable manner. Tourist
routes can be described as either being
part of the attraction (i.e. destination)
or part of the route to/from the
destination or attraction.
See Figure 12.
Passenger public transport routes
• routes that support the use of
passenger transport including
strategic bus routes as well as routes
that provide access to associated
facilities (e.g. park-n-ride areas) –
See FIGURE 8 in Section 9.0.
Bicycle routes - key cycling routes –
see bicycle routes in Strategic Bicycle
Plan report
Pedestrian routes - key pedestrian
routes – to be prepared under Pedestrian
Footpath Plan (See Section 8.0).
The functional road hierarchy is shown
in FIGURES 10 to 12.
Recommendation
• Adopt the proposed classical and
functional road hierarchy classification
of roads as shown in Figures 9 to 12.
12.2 Local Network Issues
A number of improvements have
previously been identified for some of
the “collector roads”. For example, in
a recent detailed traffic investigation
for the Garden Terrace area in
Underdale, upgrades to the Holbrooks
Road junction and Garden Terrace/
White Avenue junction were identified
for future implementation.
Table 3 provides a list of local
intersections with arterial roads that
have been considered in past traffic
reviews or are know “problem” sites.
