Why should we consider lower speeds?

    One strategy to increase safety where vulnerable road users are impacted is to set the speed limits low enough that the consequences of mistakes by a road user will not cause road trauma. Speeds above 30- 40 km/hr can increase the risk of death or serious injury in a pedestrian or cyclist crash, where motor vehicles are involved.

    • Lower speeds provide more time for drivers to react to road hazards.
    • Lower speeds decrease the distance required for a vehicle to stop.
    • Lower speeds increase pedestrians and cyclist safety, as well as other vulnerable road users and/or those crossing roads;
    • Lower speeds reduce the chance of being involved in a crash, and result in less severity in injuries and property damage, should a crash occur.
    • Lower speeds result in lower fuel consumptions resulting in a reduction in greenhouse gas emissions (and $ savings to vehicle operators).
    • From an economic perspective, 40km/h speed limits are a cost-effective option to improve road safety, allowing the City to focus on physical road safety treatments on high trafficked roads, that may attract higher cost solutions.

    What are the statistics?

    Some Fast Facts to think about:

    • 32% of the City of Kalamunda population is aged over 60.
    • 12.9% of our population is aged under 10.

    Would the existing traffic calming devices remain?

    The City plans to design upgrades for Haynes Street as part of an ongoing plan to upgrade the Kalamunda town centre area. The upgrade designs will include traffic calming measures to ensure that traffic is kept at appropriate speeds for the speed zoning and environment.

    The speed humps in Haynes Street are presently proposed to be replaced with sinusoidal speed humps, and all pedestrian crossing locations moved away from the speed humps to stop the misinterpretations and conflicts.

    What is happening at the Pedestrian Crossing at Canning Road?

    • A separate project is being planned, for a pedestrian signalised crossing of Canning Road.

    How can I provide feedback?

    The City of Kalamunda is encouraging residents to provide feedback by completing our Survey, or alternatively, written submissions can be submitted to the City via:

    Online: engage.kalamunda.wa.gov.au

    By Post: PO Box 42, Kalamunda, WA 6926.

    In Person: 2 Railway Road, Kalamunda WA 6076

    By Email: enquiries@Kalamunda.wa.gov.au

    Where can I get more information?

    For more information contact the Asset Planning Team at the City of Kalamunda on (08) 9257 9999. We will also keep you informed through website updates, by telephone or face-to-face conversations if that is your preferred method of communication. Please let us know.

    When will we see the results?

    Following the public comment period, the Community feedback will be gathered and reviewed. The results of all the feedback will also be used to guide strategic and asset planning initiatives throughout the City.

    The results of the community survey will be presented to Council, early this year (2021), along with the results of a technical review. This will help them make future decisions relating to local road safety.

    Whilst the City does not have the legal ability to change speed zones – this is the responsibility of Main Roads WA – it is our responsibility to ensure we are aware of our community’s views and advocate to Main Roads WA [External Link] on behalf of City of Kalamunda residents.
