Royal Road, Massey - Speed Humps Royal Road, Massey - Speed Humps

Consultation status: closed 17 March 2017

We are proposing to make the following changes on Royal Road, Massey:

  • Install speed humps outside 303, 311, 323, 337 and 347 Royal Road.
  • Install side islands outside 297-299 Royal Road.
  • Install new signage as required along Royal Road.

Why the changes are required

Royal Road has been identified as a high priority for speed calming measures, this in response to safety concerns raised by the public, reported crashes, and existing development in the area. The proposed improvements aim to reduce drivers' speeds and ultimately improve road safety.

Thank you everyone for your feedback.

The proposal received mixed feedback with some concerns raised by respondents. After reviewing this feedback and all other supporting evidence, the proposal will proceed without changes to the next stage of detailed planning.

Specific feedback and proposed solution

  • Question about why installing speed humps on Royal Road is needed. We have received numerous requests from local residents concerned about high speeds and boy racer behaviour in the area. Our investigations have shown, during the past five years, four crashes resulting in four injuries, were reported along this section of Royal Road. Speed was considered to be a contributing factor. A traffic survey conducted over a 7-day period. This survey showed the majority of vehicles were travelling above the posted speed limit.
  • Enquiry about why speed humps are proposed at these locations. Royal Road is classified as a Local Road from the eastern cul de sac end to its intersection with Spargo Road. Beyond the intersection at Spargo Road, Royal Road is classified as a Collector Road and it’s primarily designed to accommodate higher traffic volumes. Speed bumps would affect the capacity and level of service on this route, cause discomfort for bus passengers, and result in on-going maintenance costs due to the high stress the speed bumps would endure. For these reasons Auckland Transport does not support additional speed bumps beyond the Spargo Road intersection.
  • Concern that the side islands might cause congestion near the shops. The proposed plan is not expected to cause additional congestion near the shops at the property, 297-299 Royal Road. The proposed side islands will provide a visual narrowing effect which discourages drivers from speeding. Sufficient width will be provided between the side island to permit two-lanes of traffic (one in each direction) at all times. Such narrowing treatments are common at entrances to local residential areas.
  • Question as to why the speed humps are so close together. Traffic calming measures, such as speed bumps, are typically installed at 80-120 metre intervals as any spacing outside of these ranges have shown to be less effective. The proposed speed bumps follow this principle.
  • Statement that speed humps are uncomfortable to drive on. It is best to approach speed bumps at the appropriate speed, as this improves safety and minimises the chances of an unpleasant ‘bump’.
  • Requests for additional works including traffic signals at the Granville Road/Moire Road Intersection, a digital speed warning sign or end of road warning signs. If you would like your request to be considered by AT for future development works, please provide feedback here.

Next stage

We expect to introduce this work throughout 2017/18, subject to any further changes in design or funding issues. Contractors will issue 48-hour notice to all residents in the area prior to starting construction work.
