Restrict traffic speeds

Where could this be used?

Restricting traffic speed should be a key component of any response that involves reclaiming part of on-road space for pedestrian movement or waiting areas. While these reclaimed spaces require delineator devices to separate users from vehicles, restricting traffic speeds (to 30km/h is recommended) can reduce risk significantly.

Key considerations when implementing

The ‘Relevant regulation and legislation’ page outlines approaches to installing ‘emergency’ speed limits during COVID-19 responses that seek to improve safety. Where there is significant conflict between traffic and people walking and cycling, projects should implement physical measures that slow vehicle operating speeds in addition to setting a lower speed limit.

Relevant regulation and legislation

The graphic above illustrates a range of possible measures:

• Temporary speed humps – The range of heights and widths available allows projects to select products that deliver the speed reduction rating appropriate for the location.
• Kerb build-outs (narrow intersection) – These require drivers to perform a tighter cornering manoeuvre, reducing vehicle speed through the intersection and improving the safety of people crossing the road.
• Kerb build-outs (narrow carriageway) – Often in pairs (on either side of the road) the narrowing effect on road width encourages slower speed.
• Signage – This is a legal requirement for implementing lower speed limits during COVID-19 responses, and an important visual cue to drivers who may be familiar with the location and used to its pre-COVID speed limit.

For each of these measures, it is important to select materials appropriate to the type and frequency of use and duration of the response. For example, cones may not be the most suitable material in areas where they are prone to being frequently knocked down or moved, where an installation is intended to be in place for a longer period of time or where lower cost, effective alternatives exist.
