6 Environmental assessment
This chapter describes the potential environmental impacts associated with the
proposal’s construction and operation. Proposal-specific safeguards and
management measures have been identified to mitigate identified potential impacts.
These are reported at the end of each assessment section and summarised in
Chapter 7.
6.1 Traffic, transport and access
This section identifies and assesses the proposal’s potential impacts on traffic
movement, transport and access. Appendix C contains a traffic and transport
specialist study prepared by Parsons Brinckerhoff to support the REF, with relevant
information summarised below.
6.1.1 Method
Study area
The assessment study area considered the proposal’s effect on traffic movement,
transport and access throughout the five precincts shown in Figure 1-1.
Method and assessment criteria
The traffic, transport and access assessment was undertaken in accordance with:
Roads and Traffic Authority Guide to Traffic Generating Developments (Roads
and Traffic Authority, 2002)
Roads and Maritime Services Traffic Modelling Guidelines (Roads and
Maritime, 2013)
Austroads Guide to Traffic Management (Austroads, 2014).
The assessment:
Identified existing and future traffic, transport and access patterns into, out of
and across the study area
Identified and assessed how the construction work and resulting operational
changes would impact on traffic, transport and access
Assessed the localised intersection and road corridor performance changes
and access impacts across the study area as a result of the proposal
Identified adverse impacts that would need safeguarding or managing under
the proposal.
Construction impacts would be affected by the time taken to install the improvements
at each of the 17 locations described in Chapter 3. Throughout this section,
construction impacts have been assessed by considering the following time periods:
Short-term work lasting one to two weeks in total
Medium-term work lasting up to three months in total
Long-term work lasting over three months in total.
