Measurement methods for the noise emission properties of road surfaces

The objective of this Work Package (WP) is to prepare as completely as possible for the international and European standardisation of measurement methods for representative and accurate characterisation of road surface noise properties. Different methods such as the Statistical Pass-By (SPB) and Close-Proximity (CPX) methods may have somewhat different purposes and use, but they shall be as consistent as possible. They shall also be stable over a foreseeable time period.

The ultimate aim is to provide a draft for standardisation of a procedure for the harmonised characterisation of road surfaces across Europe, based on the available measurement methods. Another objective is to provide methods that can enable the standardised measurement of noise emission data that can be included in European road noise prediction methods. The work shall be performed in close cooperation with the ISO and CEN standardisation bodies and with the EU CNOSSOS-EU project.
