3-D noise map of Mugue Dong of the Ulsan City has been constructed. Comparing with the measured noise level, the predicted noise level has been confirmed for its accuracy. Correction factors for better prediction result using the constructed noise map have been investigated proving that its method is useful. The procedure of noise map construction method has also been introduced using RLS-90, Cadna A.

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 map. This conflict noise map is useful to assess the present urban noise and to make the better life in complicated urban life.

Air pollution and traffic noise from roads distributed near residential area has been a major social problem. In this study, an environmental pollution map for a residential area of Shihung-city was made by an expectation model based on hourly traffic volume change. Using the result from the model, a plan to reduce population in the residential area was established. The result of the modelling is summarized as follows: 1. At peak traffic hours (18 o'clock), 301-500 degree in hazardous and $d_{25}$ degree (25% of the residents are suffering extremely from the noise) in noise pollution were predicted in Jeongwang Main Road in Shihung city. 2. The calculated critical pollutant standard index, PSI showed the air pollution level, especially PM-10 high enough to require re-entrainment. 3. It was expected air pollution would extensively extend over the area distribution of each degree. However, noise pollution problem was limited to the area near roads.

본 연구에서는 실시간으로 개별 차량에 대한 소음 예측 시뮬레이션을 통해 매 순간 소음지도와 Lmax, Lmin 등을 얻을 수 있는 소음 예측 모델을 제시하였다. GIS 지형처리 기법을 이용해 공간 모델 처리 기법을 바탕으로 실시간 교통소음예측 시스템 모델을 제안하고, 객체지향기법을 이용해 개발하였다. 실시간 소음 시뮬레이션 모델을 이용하여 교통 흐름의 변화에 따라 소음레벨, 소음지도 변화, Lmin, Lmax값을 한눈에 파악하거나 비교할 수 있다. 현장에서 수행한 소음측정치와 예측치를 비교한 결과, 대부분 거리에서 Leq는 2~3db, Lmax는 3~4db 이내의 차이를 나타내어 소음예측의 신뢰성이 양호함을 확인할 수 있었다. 개발된 시스템을 이용해 민감도 분석을 수행한 결과, 대형차 비율, 차량 속도, 방음벽 높이에 따라 소음레벨의 차이를 보였고, 특히 방음벽 높이는 Leq나 Lmin보다 Lmax에 큰 영향을 미치는 것을 알 수 있었다.
