District Traffic Study

Consultation has concluded

28 February, 2019

Interested in traffic? If so, we've released the City of Cockburn District Traffic Study and draft Regional and Major Roadworks 2018-2031 VII for your comment by the end of February 2019.

It gives specific attention to traffic at these locations - west of Stock Road, Cockburn Central, Fiona Stanley hospital precinct, Jandakot Airport development, Latitude 32, Australian Marine Complex and the Cockburn Coast.

It also looks at traffic changes likely as a result of the Main Roads WA upgrades underway on the Kwinana Freeway, Armadale Road and Murdoch Drive.

We will report back to Council with your feedback in April 2019.

Background

The District Traffic Study was developed in 2006 to help assess road priorities and timing for future road network planning. A robust tool has been developed to forecast road network traffic demand. We have reviewed it every five years, in 2013 and 2018. The latest review, by engineering consultants ARUP WA, was presented to the December 2018 Ordinary Meeting of Council and is now open for your comment.

Report

The aims of the latest review were to:

  • Update the 2013 District Traffic Study
  • Prepare traffic forecasts for 2021 and 2031 including the development plans for all areas.
  • Give attention to specified areas (listed above).

Findings

It found that without any changes to the road network by 2021, there will be widespread congestion with many key roads operating at 80 % capacity or higher including:

  • North Lake Road (various stretches)
  • Phoenix Road
  • Rockingham Road
  • Cockburn Road (just south of Rockingham Road)
  • Stock Road
  • Berrigan Drive

The review recommends short, medium and long-term upgrades and actions for the City's road networks.

In particular, it says:

1. The Forest Road Link and Hammond Road extensions should be removed from the program, as they will not improve the traffic situation at surrounding intersections.

2. Narrowing Rockingham Road between Phoenix Road and Spearwood Avenue from four lanes to two lanes will have a minor increase in congestion but generally volume capacity ratios between scenarios are very similar.

3. Duplicating Farrington Road is not recommended as it will attract double the number of cars and remain congested.

5. Duplicating Rowley Road and Russell Road should proceed as they decrease congestion on Russell Road between Henderson Road and Rockingham Road, and on Russell Road between Frankland Avenue and Kwinana Freeway.

6. The Bartram Road Bridge crossing of the freeway should proceed to reduce congestion around Wentworth Parade, Hammond Road, Beeliar Drive, Tapper Road and Kwinana Freeway.

The review recommends:

  • Public transport improvements to rail and bus routes and infrastructure.
  • Further encouraging pedestrian and cycle transport modes.
  • Examining the impact of peak spreading on road infrastructure requirements.
  • Examining the timing and sequencing of development.
  • Increasing implementation of Intelligent Transport Systems.

The timing for all future major road projects is dependent on external funding from State and Federal grants as well as City. There is also a requirement for land acquisition on most of the major road projects and this impacts on project delivery times.
