소음지도를 이용한 도시 교통 소음 평가방법에 관한 연구
소음지도를 이용한 도시 교통 소음 평가방법에 관한 연구 Study on the Assessment Method of Urban Traffic Noise Using the 3D Noise mapping in Cheongju city 저자 고준희, 박수진, 장서일, 임재석, 이병찬 발행정보 한국소음진동공학회 2006년 자료제공처 KISTI 국립중앙도서관 주제분야 공학 > 기계공학 <초록> Noise mapping is performed in the city of Cheongju which has 626,614 inhabitants on a $153.41km^2$ area. This city has 71,387 buildings and 969,274m roads. Many database sets like information of roads, topography and buildings are required for making the noise map of large area. These database sets are provided by the various departments of the regional administration in Cheongju city. Using the given database sets, 3-dimensional model of topography and buildings are made to consider the multi-reflections and diffractions. A predicted noise level is compared with measured noise level of the road traffic noise. As the tool of management and decision of urban noise policy, noise map is combined into the map of land use to make the conflict noise ma
