Study of traffic conditions on Tillyard Drive and surrounding streets in Charnwood, Flynn and Fraser – September 2017 update

Project background

Roads ACT's Traffic Warrant System (TWS) identifies the need for, and priority of, traffic management and road safety measures on residential streets. This system takes into consideration the traffic volume, traffic speed, crash history and land use of each street to provide a ranking for residential roads. Tillyard Drive in Charnwood, Flynn and Fraser ranks relatively high (ranks 11 between Ginninderra Drive and Kerrigan Street and ranks 20 between Kerrigan Street and Kuringa Drive) on the 2016 TWS.

The residents of Tillyard Drive and other road users have also written to 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.

Community consultation/feedback

In November and December 2016, Roads ACT collected feedback about issues of concern from residents of Charnwood, Flynn and Fraser and the wider community.

Feedback received included 636 survey responses and 8 phone/written submissions, with 120 people attending the information sessions.

Areas of concern included:

  • safety at intersections (63% of respondents), particularly at intersections on Tillyard Drive and Lhotsky Street
  • speeding (60% of respondents), particularly on Tillyard Drive, Kuringa Drive, Moroney Street, Spalding Street, Lhotsky Street and Bingle Street
  • safety at midblocks, inclusive of pedestrian safety issues (33%) and visibility issues (33%)
  • peak hour congestion issues (37% of respondents), particularly at the Tillyard Drive intersections with Lhotsky Street and Daley Street
  • safety around Fraser Primary School (22%).

Speeding and intersection safety were identified as requiring immediate solutions. Comments received also indicated that there is general support for the introduction of traffic management measures on Tillyard Drive and surrounding streets. To view the locations identified by the community as requiring immediate action view the Tillyard Drive Community Feedback Hotspots map (PDF 512KB).

Technical analysis

The technical analyses of traffic speed, volume and crash data showed that:

  • there is a degree of speeding throughout the suburb, and particularly on Tillyard Drive, Kuringa Drive, Shakespeare Crescent, Cartwright Street, Covington Crescent, Companion Crescent, Magrath Crescent and Townson Crescent
  • traffic volumes are high on Tillyard Drive and Lhotsky Street, especially in the vicinity of the Charnwood shops
  • the Kuringa Drive midblock between Tillyard Drive and Kingsford Smith Drive and the intersections of Tillyard Drive/Lhotsky Street, Lhotsky Street/Florey Drive, Tillyard Drive/Kerrigan Street and Tillyard Drive/Daley Crescent have had the most crashes in the last five years.

Final scheme for implementation (the master plan)

Potential traffic management treatments have been 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 are to:

  • reduce travelling speeds
  • improve safety at intersections and midblocks
  • improve pedestrian safety.

The technical principles behind this scheme are that:

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

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 as funding becomes available.

The Tillyard Drive master plan (PDF 1.2MB) shows the proposed scheme.

The locations of treatments shown on the map are indicative only. The exact locations will be determined during the detailed design phase prior to their implementation.

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.

An evaluation of the effectiveness of the Priority treatments will take place six months after all their implementation. This evaluation will include a technical analysis of the scheme’s impacts and residents’ views of the extent to which the stated objectives were achieved.

Further implementation of additional treatments will depend on the results of this evaluation and funding availability.

The Priority 1 treatments are summarised below.

Tillyard Drive

  • Improvements to intersections with Crawford Crescent, Spalding Street, Kerrigan Street and Daley Crescent (south).
  • Lane narrowing between Covington Crescent and Crawford Crescent and between Barber Crescent and Kuringa Drive.
  • A pedestrian refuge island adjacent to the Bicentennial Trail.
  • Improvements to pedestrian signage near Charnwood shops.

Kuringa Drive

  • Improvements to line marking and signage.

Spalding Street

  • Lane narrowing and line marking improvements.

Kerrigan Street

  • Lane narrowing between Tillyard Drive and Shakespeare Crescent.
  • Improvements to pedestrian signage.

Shakespeare Crescent

  • Speed cushions on approach to children’s crossing.

Cartwright Street

  • Speed cushions on approach to school zone.
  • A pedestrian refuge island near Rouse Place.

Companion Crescent, Covington Crescent, Magrath Crescent and Moroney Street

  • Speed cushions to reduce travel speeds.
