With the rapid industrial development, a railway has become a main traffic means. But, rail traffic noise and vibration have become a major problem in urban area as well as a very serious issue in the living environment. Especially, noise and vibration induced by the rail operation have influenced on the residents' living nearby railway tracks. Nevertheless, adequate guidelines for the railway vibration are not yet established because of the lack of basic data and insufficient research works. In this point, the present study attempt to survey the effect and subjective response of railway vibration in urban area using questionnaire. This study also presents a basic data in establishing effective vibration plans for railway vibration in the future.

For train vibration influence assessment of newly constructed buildings in building design levels, 4 train measured vibration acceleration responses were used to compare with TR theory values and suitability of TR values was proposed. Through this TR method, construction planned grounds located near railroad areas were selected and ground vibration measurement was conducted. Through natural frequency by MIDAS, vertical acceleration response, and ground frequency from measured vibration response, TR was calculated and vibration prediction was conducted. As a result of comparing acceleration response estimate applying TR and measured value of train vibration acceleration response, it was found that it was in 3.61%~37.1% of margin of error. Clear peak of 7.19~10.61Hz in KTX, Gyungeuisun, and cement train were confirmed.
