시간별 교통량 변화에 따른 환경오염지도(대기 및 소음) 구축방안에 관한 연구

Abstract

Air pollution and traffic noise from roads distributed near residential area has been a majorsocial 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 resultfrom the model, a plan to reduce population in the residential area was established. The resultof the modelling is summarized as follows:1. At peak traffic hours (18 o’clock), 301-500 degree in hazardous and d25 degree (25% of theresidents are suffering extremely from the noise) in noise pollution were predicted inJeongwang 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 eachdegree. However, noise pollution problem was limited to the area near roads.
