This brochure summarises how the NZ Transport Agency, working together with local authorities and landowners/developers, manages road traffic noise effects on new developments and altered buildings.

For example new houses built near to an existing state highway may be affected by traffic noise. Other noise sensitive activities such as schools, hospitals, hotels, places of worship, motels and offices can also be similarly affected.

Managing the effects of road traffic noise reduces sleep and learning disturbance caused by noise exposure. In turn this helps manage reverse sensitivity effects on the state highway network.

Keywords: noise, reverse sensitivity, noise sensitive activity, manage road traffic noise, acoustics, sleep disturbance, new developments, altered buildings, noise barriers, buffer area, effects area, expressway, state highway.
