Road traffic noise

Road traffic noise is caused by vehicle engines and tyres on road surfaces.

To make a complaint about road noise email tipd.dot@nt.gov.au or call (08) 8924 7037.

The table below sets out target noise levels for particular types of road situations for residential and noise-sensitive land uses adjacent to arterial roads.

Scenario Land use scenario:
Existing residential
Land use scenario:
Existing noise-sensitive
Land use scenario:
Future residential and noise sensitive
Road scenario:
Existing road - planned significant development
Future road - currently planned
No target - no required action No target - no required action Responsibility for noise management of developments undertaken adjacent to an existing or planned future road rests with the proponent (private or government)
Road scenario:
Existing road - unplanned significant development
Where there is both a predicted increase in noise level of >5 dB(A) and the predicted noise level is >68 dB(A), target 68 dB(A) Where there is both a predicted increase in noise level of >5 dB(A) and the predicted noise level is >63 dB(A), target 63 dB(A) Responsibility for noise management of developments undertaken adjacent to an existing or planned future road rests with the proponent (private or government)
Road scenario:
Future road - not currently planned
Target 63 dB(A) Target 58 dB(A) Responsibility for noise management of developments undertaken adjacent to an existing or planned future road rests with the proponent (private or government)

The process of measuring noise also accords with Australian Standard 2702–1984 and 3671–1989.

The Department of Transport uses the CoRTN method which accords with the Australian Standards.
