Road traffic acts as a dominant noise source, and traditional regression-based approaches mainly yield 2D noise maps. This study investigates 2D and 3D GIS-driven visualization of noise using limited samples by building two models: a 2D road noise model and a 3D building noise model, which are combined into a comprehensive 3D noise map.

Road traffic is a primary noise source, causing annoyance and interference. Traditional regression models predict twodimensional (2D) noise maps, but this study explores the impact and visualization of noise using 2D and three-dimensional (3D) GIS (Geospatial Information Systems) functionalities. Two models were assessed: (i) a 2D noise model for roads and (ii) a 3D noise model for buildings, utilizing limited noise samples. Combining these models produced a comprehensive 3D noise map. Machine learning (ML) models—artificial neural network (ANN), random forest (RF), and support vector machine (SVM)—were evaluated using performance measures: correlation (R), correlation coefficient (R²), and root mean square error (RMSE) . ANN outperformed others, with RF showing better results than SVM. GIS was applied to enhance the visualization of noise maps, reflecting average traffic noise levels during weekday mornings and afternoons in the study area.  \nKeywords  \n2D noise model, 3D noise model, artificial neural network, random forest, support vector machine  \nI. Introduction  \nDespite the fact that road traffic is inevitable, its annoying sound called noise has continued to draw global attention and possible remedial measures [1–3] . Noise pollution has attracted great interest over the decade [4] . Road traffic is the most widespread source of noise in many countries, and it is the most prevalent cause of annoyance and interference [5–7] .  \nTraffic noise is generated from engine sound and frictional contact between the ground and the vehicle tires [8] . Noise generated from traffic depends on traffic volume, vehicular speed, vehicular class (heavy duty or light cars), and the type of roads [9–13] . Noise prediction is necessary where a future situation cannot be ascertained [14–16] . More so, field measurement of noise pollution seems impractical and difficult  \n Open Access.
