Abstract

교통소음공해가 도시생활에 있어서 건강에 중요한 영향을 주고 있으며 소음을 효과적으로 측정하기 위해 소음분포에 관한 소음지도제작은 매우 긴요한 일이 되고 있다. 도시교통소음지도는 소음을 조정하기 위한 효과적인 방안을 찾고 실질적인 근거를 마련하는데 도움을 주고 있으며, 소음이 도로로부터 주거지역으로 어떻게 전파되는지를 시각적으로 이해하기 쉽게 정보를 주고 있다. 본 연구에서는 도로와 거주지역간의 개발형태를 3가지로 구분하여 고려하였고, 주거지역내에서의 필지별 소음정도를 도로로부터 거리가 떨어짐에 따른 소음감쇄를 ArcGIS의 보간법을 적용하여 계산하고 그 결과를 이용하여 소음지도를 제작하였다. 그 결과 주거지역내의 교통 소음수준이 국내 환경기준을 초과하고 있음을 알 수 있었고, 각각의 필지별 소음수준을 추정할 수 있었다. 이것은 향후교통소음조정계획을 수립하거나 공시지가평가 시 활용될 수 있을 것으로 판단된다. Traffic noise pollution is a growing problem that highly affects the health of people in urban areas. In order to implement effective measures against traffic noise the noise mapping about its distribution is imperative. Urban traffic noise maps will help to establish the existing baseline so that we will be able to look for the effective way to control the noise. They will also let us see in an understandable and visual way how noise spreads from roads into residential areas. In this paper we considered three development types between roads and residential areas, and applied the interpolation of ArcGIS for noise attenuation with distance from the roads to find the noise level at the parcels positions in residential areas, and then generated the noise map using the interpolated results. Therefore we present results that the traffic noise level within residential areas exceed the national noise standard and also can estimate the noise level of individual parcels. These results can be used for traffic noise control planning or assessment of officially assessed land price in near future.
