The City of Cockburn has received requests from residents to investigate traffic calming measures on Blackwood Avenue in Hamilton Hill. A traffic assessment was undertaken in April 2021 to better understand traffic conditions and guide our planning.

Findings

Findings from this traffic assessment included:

• Average weekday traffic count: 1821 vehicles per day.
• Average vehicle speed: 60km/h to 69km/h (up to 19km/h above the permitted speed limit).

Incident records were also reviewed which showed:

• Six crashes, including:
  • one medical,
  • one hospital,
  • three major property damage, and
  • one minor property damage.

These findings place Blackwood Avenue in "Criteria A" of the City's Local Area Traffic Management Investigation Policy. This means speed humps are recommended to reduce vehicle speeds and improve safety. Humps are also recommended on the adjacent road, Ely Street. For more information, please view the Frequently Asked Questions here.

Next steps

Speed humps will be installed at various locations along Blackwood Avenue and Ely Street in mid-2022. A draft design, showing the proposed hump locations, has been prepared. View the draft design here.

The City is seeking feedback from residents on the proposed design. At this stage, it is only a draft.

Comments will be considered in the final design. The City must also consider a range of site constraints and road design principles that limit the potential placement of speed humps and types of traffic calming devices used.
