Road traffic noise can be a major nuisance, particularly in residential areas. We are working to reduce overall traffic noise levels, and to limit noise impacts from new or upgraded roads.
Traffic noise levels are investigated during road planning. We consider the impact on noise-sensitive areas such as residential dwellings, hospitals, motels, schools and libraries.
The VicRoads Traffic Noise Reduction Policy details acceptable noise limits. If these limits are exceeded, noise reduction measures may be needed.
Noise reduction measures include:
- low noise road surface
- noise walls
Noise walls are usually made from timber, plastic, concrete or steel. Recycled materials are under consideration for future noise walls.
VicRoads has a program of noise wall retrofitting at sites most affected by high levels of traffic noise.
Noise and pollution from freight activities is considered in the planning of Victoria's freight network. The Truck Action Plan encourages trucks onto routes optimised for freight. It aims to protect local neighbourhoods from existing and new freight developments.
Development along identified road reservations and declared roads must be compatible with future traffic noise levels.
