vehicles waiting at a controlled intersection approaching Yardhurst Road

Project Introduction

We’re installing a raised safety platform at the intersection of Yaldhurst Road and Peer Street to encourage motorists to slow down when approaching the intersection, providing a safer, slow-speed crossing space for pedestrians.

About the project

We know that 55 percent of crashes in Christchurch happen at intersections. The SH73 Yaldhurst Road/Peer Street intersection carries around 17,000 vehicles a day and is known to have speed issues.

In the last ten years, there have been 60 crashes at the intersection resulting in a death and three serious injuries.

We’re installing raised safety platforms at each approach to the intersection to make it safer for students and staff at Villa Maria College, children at St Marks Anglican Preschool and and for all road users, whether walking, cycling or driving.

Raised safety platforms are designed to slow traffic, so that if something happens, vehicles are travelling slow enough to give people time to react to avoid a crash. If a crash does happen, the risk of death and serious injury is reduced by 40 percent.

The work we have planned compliments safety improvement works that the Christchurch City Council are proposing around Church Corner.

  • Key features

    We’re installing raised safety platforms and new line markings at each approach to the intersection of SH73 Yaldhurst Road and Peer Street to help make it safer for everyone.

    Raised safety platforms slow drivers down as they approach and leave an intersection making it safer for people crossing the road. They’re designed so that if something happens, vehicle speeds are slow enough that there is time for people to react to avoid a crash and to reduce potential injuries if a crash does happen.

  • Project timeline

    We plan to install the raised safety platforms between February and March 2024. We will be coordinating construction works with the Christchurch City Council’s proposed works around Church Corner to minimise the impact to the community. We will provide an update before the work starts.


Frequently asked questions

  • How do raised safety platforms differ from speed humps?

    Raised safety platforms (RSPs) are substantially different to speed humps that are typically used for traffic calming in residential streets and at locations such as schools. RSPs have a smoother profile and are designed to encourage vehicle speeds of around 50km/h, at locations where the predominant risk relates to side-impact vehicle-to-vehicle crashes and 30km/h at locations where there is a heightened risk of crashes involving pedestrians or cyclists, like at the Yaldhurst/Peer Street intersection. 

  • RSPs are not the same as speed humps

    The ramp grades on RSPs are designed to achieve lower speeds while minimising driver and passenger discomfort. RSP grades are softer than those used for speed humps and are typically 1:15 to target 30km/h (pedestrians and cyclists) and 1:25 to target 50km/h (side-impact). RSPs will also typically have softer departure gradients (around 1:30 or 1:35) where possible.

  • What additional noise will be created by RSPs?

    Noise was identified as a potential concern as part of planning for the first installations in Victoria. However, from discussions with VicRoads, it is understood that noise did not materialise as a significant issue following construction at any of the trial sites.  

  • Raised safety platforms and raised pedestrian crossings and impacts on emissions

    As one of the main sources of increased transport emissions is through vehicle acceleration and braking. In New Zealand, the raised safety platforms on which the pedestrian crossing is installed, have been designed to allow a driver to comfortably travel over them, but at a speed that is safe for pedestrians, while at the same time minimising the amount of braking and acceleration on the approach and departure from the raised safety platforms. This type of design minimises any effects that the raised safety platforms have on carbon emissions.
