3D 소음시뮬레이션시 각 고시에 따른 적용인자 중 방음벽성능에 대한 적용방법은 기본프로그램값을 적용하는 경우가 많았다. 이에 실제 소음측정결과와 교통량을 적용하여 3D 소음시뮬레이션시 방음벽 재질별로 적용한 결과 설치된 방음벽 제원을 가장 유사하게 적용할 경우 소음예측결과가 오차범위가 적어지는 것을 알 수 있었다. 이렇듯 3D 소음시뮬레이션 시 모든 예측인자와 설치인자들을 정확히 적용하여야만 정확한 예측결과를 통한 검증과 저감방안을 계획할 수 있다.

This paper presents statistics that evaluate the results of a precision safety inspection and precision safety diagnosis over the past five years. The impact and degree of poor inspection and diagnosis were analyzed by dividing contract amount by rate, implementer, and managing body. The purpose of the analysis is to elicit problems and measures in the system.

In recent years, public complaints against railroad noise by KTX and Ordinary train have been rising. Regulation of railways noise uses same standard without distinguishing the type of railroad cars. According to the type of railroad cars, the frequency characteristics of emitting noise is different. Therefore it is requested to know how the public response vary to each types of railroad cars. The noise annoyance from three types of trains(KTX, electric train, diesel train) was analyzed by jury evaluation test for assessing the effect of frequency characteristics. The numerical results by a semantic differential method showed that annoyance response to three type of trains depended on the frequency characteristics. As a result, this study proposed that the KTX could have a bonus level of maximum 2.9 dB(A) compared to ordinary train.
