Abstract
Quantification of traffic noise levels in urban areas can be especially useful for environmental and public health policies. A statistical model is proposed here for this quantification in small urban areas. The model is nonlinear and mixed, with two components: a fixed component for traffic noise emission (source effect) and a random component for assessing traffic noise propagation. The proposed model requires only sample data and has been used to estimate basic noise indicators established in European standards. A composite indicator, the Lden indicator, has been computed and used to draw up a noise ranking of urban areas. The proposed approach is applied to the city of Leganes (Spain).
