Noise

Road traffic noise is recognised as a concern for people living along motorways and main arterial roads with high traffic volumes. Noise is defined as unwanted sound produced by vehicles, and the interaction between vehicle tyres and the road surface.

Transport and Main Roads is the key government agency responsible for the management of traffic noise from state controlled roads. Noise control is part of the successful delivery of road infrastructure projects and is considered during the transportation planning and road design phase.

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

Refer to the Transport Noise Management Code of Practice for further information.
