A proposal for improved source model for predicting railway noise in Sweden, SP Report 2014:60

Uppdaterade bullerberäkningsmodeller, emissionsdata

Sammanfattning:
The current noise prediction model used in Sweden for rail traffic noise, NMT96, was finalised in 1996. Since then nearly 20 years passed. At European level, advanced noise prediction methods have been developed based on state-of-the-art scientific, technical and practical knowledge about environment noise assessment. Such examples can be e.g. TWINS for railway noise, the Harmonoise-Imagine methods for road, railway, aircraft and industry noise, and Nord 2000 Road for road noise in Nordic countries. Moreover, for strategic noise mapping over European member states, it has recently been decided that the European common noise assessment method, CNOSSOS-EU, is mandatory to be used. To follow these developments in fighting environmental noise, the Swedish Transport Administration (Trafikverket) requires to update the prediction models for road and rail traffic noise as well as to elaborate noise emission data for the extended noise source models.
This pilot study aims at proposing an improved source model for railway noise, with railway track standard respected. Explicitly, rail roughness, track type, and noise measures on a track should be taken as input parameters in the source model
