The residents of Maribyrnong Avenue and other road users have written to Ministers, members of the ACT Legislative Assembly and Roads ACT regarding their concerns about traffic volumes, speeding and other road safety and amenity issues on this street.
Roads ACT has developed the Traffic Warrant System (TWS) to identify the need for traffic management and road safety measures on residential streets. This system takes into consideration the total traffic volume, traffic speed, crash history and land use of each street to provide a ranking for collector roads. Maribyrnong Avenue in Kaleen ranked relatively high on the 2013 TWS.
In September/October 2013 Roads ACT collected feedback about issues of concern from residents of Kaleen, Giralang and the wider community.
The feedback received included 555 survey responses and three email/phone submissions, with 299 people attending the information sessions.
Key areas of concern included:
Speeding, intersection safety and pedestrian safety were identified as requiring immediate solutions.
Comments received also indicated that there is general support for the introduction of traffic management measures on Maribyrnong Avenue and surrounding streets. For more information view the Summary of the Maribyrnong Avenue Stage 1 consultation responses (Word 118KB) (PDF 287KB)
The technical analyses of traffic speed, volumes and crashes showed that:
*The speeds at which 85% of the surveyed traffic is travelling at or below.
Potential traffic management treatments were developed to address the feedback received from the community as well as the results of the technical analyses of traffic data.
The objectives of the proposed scheme were to:
The technical principles behind this scheme were:

The community was consulted again in December 2013/January 2014 to seek views on the proposed treatments for improvement.
Over 480 people participated in this consultation process. The feedback received included 282 survey responses, 13 phone/email submissions and 193 people attended the public display/information sessions.
This feedback included:
The community was generally not supportive of lane narrowing on Maribyrnong Avenue and the proposed roundabout at the Maribyrnong Avenue/Diamantina Crescent intersection.

In view of the results of the technical analysis and the feedback received from the community, and considering the technical effectiveness of the proposed treatments, the final scheme has been modified. It now incorporates some alternative treatments suggested and supported by the community.
It is important to note that the final scheme is an overall 'master plan' for the area and that not all proposed devices will be installed at once. The master plan will guide the implementation of the scheme over a number of years. The works will be undertaken as funding becomes available.
The locations of proposed treatments shown on the map are indicative only, and the exact locations, as well as the detailed design of treatments, will be determined before the implementation stage.

Priorities have been assigned to the proposed treatments based on the results of the technical analysis and the feedback from the community.
An evaluation of the effectiveness of Priority 1 treatments will take place six months after their implementation. The evaluation will include a technical analysis of the scheme's impacts and the residents' views of the extent to which the stated objectives were achieved. Further implementation of Priority 2 and 3 treatments will depend on the results of this evaluation.

The Priority 1 treatments are summarised below.
For more information on the final scheme and the priorities for implementation view the Executive Summary of the Maribyrnong Avenue report (Word 95KB) (PDF 968KB).
The implementation of Priority 1 treatments in the area was completed in July 2015.
The objectives of the Priority 1 treatments are to:
The recommended roundabout at the Maribyrnong Avenue/Ashburton Circuit intersection was not implemented as it was not possible to provide the necessary deflection required to control vehicular speeds nor satisfy the turning movements of a 14.5m tag steer bus without pavement widening and relocation of existing services. The high costs of the necessary pavement widening and relocation of services was also beyond the current funding allocation. As such, improvements to this intersection will be considered under future capital works programs when adequate funding becomes available.
The effectiveness of the implemented priority 1 measures was evaluated in early 2016 to determine if they had achieved the stated objectives of reducing travelling speeds and increasing overall road safety.
The technical evaluation included a 'before' and 'after' comparison of traffic speed, volume and crashes. Community feedback was also sought regarding the effectiveness of the treatments, and a total of 364 responses were received. The key findings from the evaluation are outlined below.
Traffic conditions on Maribyrnong Avenue, Daintree Crescent, Onkaparinga Crescent, Staaten Crescent, Alberga Street and Ashburton Circuit will continue to be monitored. Any changes to the existing traffic management scheme or implementation of other treatments will be considered in future programs, when funding becomes available, in consultation with residents of the respective streets.
