A simplified approach for making soundmaps within a GIS software

Résumé

This study is a part of pluridisciplinary project on the assessment of the environmental impacts of an urban mobility plan and of their socio-economic consequences. Particularly, one of the objectives of the project is to be able to build and to compare soundmaps (or noise maps) of large cities, in function of several mobility plan parameters. Considering the computational time that is required for making noise maps with classical software, a simplified approach of sound propagation in urban areas has been proposed. The particular interest of the proposed approach is that the model has been integrated within a two-dimensional geographic information system software, and is able to produce full noise map in few hours only. The heart of the model is based on French standard NMPB2008 method, whose noise emission and sound propagation calculations have been simplified. In addition, in order to reduce computational times and memory resources, algorithms have been optimized for the calculation of the direct, reflected and scattered field in large urban areas.
