Assessment
This page contains links to information on the road-traffic noise assessment required under our ESR Standard, and provides resources to support this process.
Barriers
Noise barriers (bunds and walls) are probably the most widely recognised form of noise mitigation used for state highways.
Buildings
Road-traffic noise is generally assessed and mitigated outside of buildings. However, acoustic treatment of buildings is sometimes required to achieve reasonable internal noise levels.
Construction and maintenance noise
Noise and vibration from construction and maintenance activities is an important consideration. We have prepared a number of resources to assist our staff, consultants and contractors in the management of construction noise and vibration.
Planning
Land use planning attempts to address noise in a strategic manner. It can provide consistency and certainty when implemented early in the planning process. Land use planning approaches to control the effects of noise can occur at a national, regional or district/city level and can be complemented by other measures such as bylaws (for example restrictions on engine braking) and urban design.
Research and information
This page has been developed to list key sources of information for researchers including: research, New Zealand Standards, web site links, presentation and training.
Standards, guidelines and specifications
The following guidance and specifications set out Waka Kotahi NZ Transport Agency’s expectations of the required minimum levels of service, consolidate practical experience gained by the organisation and disseminate specific specialist knowledge relating to highway planning, construction, operation and maintenance so this knowledge can be applied efficiently and consistently across the network.
Surfaces
The type and condition of a road surface can have a noticeable effect on the noise levels experienced by residents adjacent to state highways.
Vehicle noise
The Ministry of Transport administers a suite of regulations that seek to control sound emitted from an individual vehicle.
Frequently asked questions
There are a number of factors that contribute to noise and vibration effects in relation to road traffic and road construction projects. Read our frequently asked questions to find out more about where noise and vibration comes from, how it may affect you and what the Transport Agency can do to manage these issues.
