Road traffic noise is recognised as being a concern for many people living along motorways and main arterial roads with high traffic volumes. It may be defined as an unwanted sound produced by the interaction between vehicle tyres and the road surface.

Transport and Main Roads is the only government agency responsible for the management of road traffic noise and we play a major role in transportation planning and road design. Noise control is part of the successful delivery of road infrastructure projects.

We aim to provide efficient road transport infrastructure, minimising noise impacts from state-controlled road construction and maintenance activities.

Transport noise management code of practice has further information.
