Description

When standard GIS are used for traffic noise impact assessment, this has usually been done by using the built-in buffer- and overlay tools. However, recent research by IFP and TetraPlan Ltd. shows that the use of these tools can result in a crude and systematic misestimation of the noise level along building facades and thereby also the number of residences affected by noise of certain levels. New methods developed by TetraPlan Ltd. consider the barriers of different buildings as well as noise reflections. As part of the work a methodology for creating a 'synthetic' 3-D model based on GIS-maps and the Danish Building register has been developed. The work builds on two pilot projects ('Svendborg' & 'Middelfart') named after the concerned cities.
In the second phase of the GIS-T programme, the evaluation of traffic noise based on detailed map and register data are continued. A method to split buildings in floors and apartments has been developed. Based on this, analyses of coherence between noise and different socioeconomic data from the Danish Building Register (BBR) and personal register (CPR) are carried through. This provides a first step in the direction of analyses of traffic noise's relationship with socioeconomic data.
