Abstract [en]
The Nordic prediction model from 1996 is still used for road traffic noise predictions and noise mapping purposes in many cases in Sweden. The model is restricted to A-weighted levels and the vehicle categories only take light and heavy vehicles into account. Weather conditions and ground effects are simplified. The subsequent Nord2000Road model can be used for noise predictions in more complex situations. Nord2000Road uses third octave bands, an advanced outdoor propagation model and more categories for vehicles and ground. Recently the CNOSSOS-EU model has been developed in Europe and can be used for noise mapping purposes according to the European Noise Directive in the future. CNOSSOS-EU uses octave bands and similar vehicle categories as Nord2000Road. The source model as well as the propagation model differs from Nord2000Road. In 2015, a measurement campaign of noise emission in real traffic was conducted in Sweden. This paper presents updated input data for the Nord2000Road source model as well as national Swedish correction terms for rolling noise in the CNOSSOS-EU model to better represent the recent measurement results.
