Traffic noise has become a critical issue in urban areas as a result of rapid transportation development. Many health problems including high blood pressure and hearing loss are closely related with noise. This hazardous nuisance may be more likely to be suffered by disadvantaged social groups. To examine which groups are more exposed to traffic noise and the significance of inequities, this study investigates the spatial dependency of traffic noise distribution in an urban area, and models the relationship between traffic noise and social factors including age, gender, race, education level and poverty rate. The study site locates in the Atlanta Metropolitan Statistical Area, which is the ninth-largest metropolitan statistical area in the United States. A transportation noise map released by U.S. Department of Transportation (DOT) in 2017 and the American Community Survey (ACS) estimates in 2015 are used to derive noise information and socioeconomic factors. This research provides spatial insights into the environmental justice issue regarding residential exposure to traffic noise, and draws attentions to alleviating social inequities in exposure to noise pollution and resulting social discontent.
