State highway noise mapping: Auckland motorways case study

The NZ Transport Agency initiated a strategic noise mapping exercise in 2009. The aim was to generate noise maps covering the 220 km motorway network in Auckland, which could then be used to inform and identify priority areas for noise mitigation. The 2009 exercise was repeated and refined in 2012 to address a number of short comings, in particular, the limited geographical coverage of the maps due to incomplete input data, as well as output inconsistencies associated with the mapping methodology. Careful project scoping, supplier selection and project management enabled the efficiency of the 2012 mapping process to be enhanced and streamlined. Ultimately a comprehensive and consistent set of noise maps has been generated for the Auckland motorway network for a base year of 2006 as well as for 2011. This paper explores the lessons learnt from the noise mapping exercise. It discusses the benefits of optimising the use of specialists in geographical information systems (GIS), acoustics, transport policy and asset management. The paper also discusses how the information provided by the maps is now being used to shape the Transport Agency’s response to road-traffic noise issues in Auckland.
