Transport noise and vibration can cause a range of impacts on people and communities, and can negatively affect their wellbeing. Noise and vibration can come from road-traffic as well as from construction and maintenance activities.

We manage these effects during construction and operation of land transport infrastructure by:

  • assessing potential noise and vibration effects of our activities
  • using land-use planning approaches to control the effects of noise
  • managing noise and vibration during construction to avoid unreasonable effects on people and communities
  • considering acoustic effects when exploring transport design options
  • constructing noise barriers
  • using low-noise road surfaces
  • acoustically treating buildings.

Below you will find requirements, guidance and information relating to all of these mitigation measures.

For an introduction to road-traffic and construction noise and vibration, read our frequently asked questions.
