Streeton Drive, Weston Creek traffic study - updated August 2015

Project background 

The residents of Streeton Drive 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. Streeton Drive in Weston Creek, from Hindmarsh Drive in the north to Namatjira Drive in the south, ranked relatively high on the 2009 TWS.

Stage 1 Community consultation/feedback 

In November/December 2012, Roads ACT collected feedback about issues of concern from residents of Chapman, Stirling, Rivett and the wider community.

The feedback received included 163 survey responses and four phone submissions. Twelve people also attended an information session at Stromlo School on 6 December 2012.

Key areas of concern included speeding (58% of respondents), parking issues (42%), 'rat running' along Streeton Drive (31%), excessive traffic volumes (29%), intersection safety (29%) and pedestrian safety (27%).

Speeding, excessive traffic volumes and parking issues were identified as requiring immediate solutions. Comments received indicated some concern over placing speed humps or chicanes on Streeton Drive, and preferred treatments on all streets included roundabouts, lane narrowing and pedestrian crossings. 

Technical analysis

The technical analysis of traffic data showed that 85th percentile speeds* are above the speed limit on Streeton Drive, Namatjira Drive, Darwinia Terrace, Perry Drive, Fremantle Drive and Bunbury Street. Traffic volumes on Streeton Drive, Namatjira Drive and Perry Drive also exceed the acceptable limits for the road environment.

Proposed traffic management concepts

Two traffic management concepts were developed to improve traffic conditions on Streeton Drive, as well as issues on surrounding streets identified during the analysis of traffic data and from community feedback.

The objectives of these concepts were to:

  • reduce travelling speeds
  • improve safety at intersections
  • improve pedestrian safety
  • reduce traffic volumes
  • discourage "rat-running". 

The technical principles behind these concepts were:

  • to reduce speeds all-day every day (24/7), it is necessary to place physical devices on the road so that motorists must slow down.
  • devices must be spaced evenly along the road to achieve the desired travel speed at, or below, the posted/default speed limit.
  • different devices serve different purposes, have different levels of effectiveness, and vary in construction cost. However, the aim of all these devices is to reduce speeding and encourage through-traffic to use the surrounding arterial roads.
  • slower speeds and devices which create safer crossing opportunities for pedestrians would also help to improve the safety and amenity of residents.

Summary of Proposed Treatments 

 

Stage 2 Community consultation/feedback

The community was consulted again in March/April 2013 to seek views on the proposed treatments for improvement.

The feedback received included 126 survey responses and 10 phone/email submissions. Fifty two people also attended the public display/information session at Chapman Primary School on 21 March 2013.

This feedback included:

  • 52% of respondents preferred Concept 1
  • 22% of respondents preferred Concept 2
  • 26% of respondents did not support either concept
  • priority treatments were identified to address parking near the netball courts and pedestrian safety near the shops and school
  • roundabouts were also supported at the Perry Drive / Namatjira Drive intersection and the Streeton Drive / Namatjira Drive intersection.

Final master plan 

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 is based on Concept 1 but also 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 due to annual budgetary constraints.

Priorities and Staging

Priorities have been assigned to the proposed treatments based on the results of the technical analysis and the feedback from the community.

The priority 1 treatments are summarised below.

Streeton Drive

  • Marked shoulders:
    • fromHindmarsh Drive to the roundabout at Darwinia Terrace (including near the netball courts)
    • betweenNamatjira Drive and Fremantle Drive (south)
  • Channelised right turn arrangement at Sherratt Place (netball courts)
  • Pedestrian refuge island between Hindmarsh Drive and Fremantle Drive
  • Pedestrian refuge island north of the roundabout at Darwinia Terrace

Darwinia Terrace

  • Pedestrian refuge island between Streeton Drive and Thring Street
  • Pedestrian refuge island between Thring Street and Perry Drive

Bunbury Street

  • Two centre islands:
    • close toFremantle Drive intersection (near walkway)
    • near ShentonCrescent.

The priority 1 treatments were implemented in mid-2014.

Evaluation of the effectiveness of the Implemented Scheme 

In early 2015, six months after the implementation of the priority 1 measures, the Chapman, Rivett and Stirling traffic management scheme was evaluated to determine if the measures in place had achieved the stated objectives of reducing travelling speeds and traffic volumes 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 271 responses were received. The key findings from the overall analysis are outlined below.

Streeton Drive

  • Travelling speeds have been reduced by 0.6 km/h on Streeton Drive.
  • About 41% of all respondents and 44% of Streeton Drive respondents are supportive of the measures implemented on Streeton Drive.
  • Feedback received indicated the need for channelised right turns at the intersections with Bangalay Crescent and Fremantle Drive.

Darwinia Terrace

  • Travelling speeds have been reduced by 3.5 km/h on Darwinia Terrace.
  • Traffic volumes have been reduced by 2-14% on Darwinia Terrace.
  • About 48% of all respondents are supportive of the measures implemented on Darwinia Terrace and 26% of respondents are unsure of their support.
  • Feedback received indicated concerns about speeding and traffic safety along Darwinia Terrace between Hindmarsh Drive and Perry Drive.

Bunbury Street

  • Travelling speeds have been reduced by 2.5 km/h on Bunbury Street.
  • About 34% of all respondents are supportive of the measures implemented on Bunbury Street and 49% of respondents are unsure of their support.
  • Feedback received indicated continued concerns about high speeds and rat-running on the road.

Traffic conditions on other streets

  • Travelling speeds have reduced by up to 7.6 km/h on Namatjira Drive.
  • Traffic volumes have increased by 4 – 7% on Namatjira Drive. There is a slight reduction in traffic volumes on Perry Drive, Fremantle Drive, Casuarina Street and Bangalay Crescent.
  • Feedback received indicated there are still concerns regarding traffic safety, excessive traffic volumes and rat-running through Namatjira Drive, Perry Drive, Thring Street and Fremantle Drive.

Traffic conditions on the above streets in Chapman, Rivett and Stirling 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.
