Road noise and vibration services offered by GHD include measurement, analysis and assessment of noise and vibration for a variety of areas including assessment of existing levels, planning studies, business case and options assessments, all stages of design, commissioning and post-construction assessments.
GHD has extensive experience with road traffic noise measurement and modelling. This enables our team to develop robust noise models in SoundPLAN and CadnaA software informed by real-world site-specific observations and monitoring.
With in-house GIS specialists, GHD can combine spatial information, 3D design models, aerial imagery and building footprints with noise or vibration prediction model results to produce clear and accurate maps in web-accessible or legacy formats for internal or public consumption.
Major Road Projects
Globally, transportation noise is recognised as one of the most significant contributors to overall environmental noise and associated adverse community health impacts. Roads offer individual flexibility compared to other forms of transportation for passenger travel and freight, however the impacts from noise and/or vibration are often high near to the road corridor.
Urban planning and corridor selection can help to minimise road traffic noise impacts at the concept or planning stage. Once the route is selected, noise mitigating elements can be incorporated into the design to achieve the desired performance objectives.
Identification of noise or vibration issues on an existing road may also drive the review and potential implementation of mitigation measures.
GHD has experience in all phases of road projects, including:
- Initial concept development, planning and business case.
- Route development and options assessment.
- Detailed design and third party review.
- Environmental studies and approvals for construction and operational noise or vibration.
- Construction phase monitoring and support.
- Post-construction verification and testing.
- Ad-hoc and routine noise and vibration studies at a local or network extent.
- Reporting and consultation with relevant jurisdictional authorities and stakeholders.
- Integrated acoustic engineering design of associated infrastructure such as transport hubs including HVAC, public address system intelligibility, user comfort and environmental noise considerations.
Developments near roads and traffic generating developments
GHD has extensive experience in assessment of road traffic noise and vibration impacts on developments, also impacts associated with traffic generating developments including:
- Concept level assessment for land-use developments.
- Assessment to support planning and council approvals.
- Monitoring of existing noise and vibration levels.
