A Review on GIS-based Approach for Road Traffic Noise Mapping


Objectives: Road traffic noise pollution is identified as one of the serious alarms that influence the attribute of the urban regions. This study highlights the different models used for noise mapping using GIS. Methods: Interpolation (krigging) method can be used to develop different noise contour maps. Noise emission levels are calculated from many sound propagation models like ISO 9613:1996, Calculation of Road Traffic Noise (CoRTN 88), Harmonoise Noise Prediction Algorithm and Nord 2000. Findings: In study of road traffic noise mapping, noise levels have been predicted using a specially developed noise computer models. The output results of the computer noise models can add as input data for a GIS. The interpolation methods available in GIS can develop noise contour maps. Application: This study highlights the different Geographic Information System techniques applied for the noise mapping.
