Speed management

30kmh signSafer Speeds are a key plank of New Zealand's road safety strategy. Reduced speeds (through lower speed limits, traffic calming, and other speed management initiatives) have been demonstrated here and internationally to reduce both the likelihood and severity of traffic crashes.

ViaStrada has championed greater use of speed management within New Zealand for over a decade. Our efforts in this area include:

  • Advising road controlling authorities on the development of speed management strategies and speed limit setting procedures
  • Undertaking research into speed-related initiatives in New Zealand and overseas
  • Developing scheme designs for traffic calming and other speed management treatments
  • Delivering various papers and presentations on speed to various industry conferences
  • Representing the Transportation Group NZ on the Safer Speeds reference group for the 2020 NZ Road Safety Strategy
  • Providing technical comment to media when asked about speed related issues
  • Making representations to Christchurch City Council regarding local speed management proposals
