Contingent valuation of road traffic noise: A case study in the urban area of Quito, Ecuador

The aim of this study was to estimate the value of noise pollution generated by transportation using a discrete choice survey. This paper reports the main findings of a contingent valuation of road traffic noise in Quito, Ecuador. In this sense, it was conducted a social survey in Quito in order to identify the respondents' noise perception, and their willingness to pay in order to reduce the annoyance caused by road traffic noise. The respondents' road noise exposure levels were obtained through an RSL-90 acoustic model. The econometric model succeeded 81,43% of the willingness to pay for the validation dataset. This study contributes toward assessing the environmental costs of transport in an Andean city within a policymaking context.
