Three Typical Noise Assessment Methods in EU

This project aims at working out a reliable and accurate assessment method for high-speed railway noise, with the focus on Swedish applications. However, the method should be generally applicable if proper input data become available. The project is divided into two parts. In part 1 (Etapp A) three typical noise assessment methods in EU will be reviewed; this review will provide a solid basis for Trafikverket (the Swedish Transport Administration) to choose the most suitable parts of these noise assessment methods for building up a new Swedish noise assessment method. In part 2 (Etapp B) the following issues will be addressed, properly and smartly: To build up a noise source model, to prepare the noise source data, to integrate these parts with an advanced propagation model and to formulate a calculation approach for noise assessments of high-speed lines as well as for necessary noise measures. Moreover, the model should be possible to implement in an IT application (for high-speed lines), while not within the frame of this project.In this report three typical noise assessment methods in EU, Nord2000/2006, CNOSSOS-EU, and NMPB 2008, have been reviewed and compared. A proposal has been made for building up a new Swedish noise assessment method for high-speed railway applications.ISBN 978-91-86622-18-
