The purpose of this study is to analyze the principal causes of increases in air temperature on platforms of railway station. We analyzed the distribution of air temperature on Shinkansen platforms at Station 'A' using Computational Fluid Dynamics (CFD). We focused on the factors that influence the temperature dynamics associated with heat generated by trains and station buildings and their effect on the ambient temperature on platforms. In the case of heat generated by trains, air temperature on Shinkansen platforms increased by 4 to 7 degrees compared to when trains generated no heat. When a 50-m high station building was located on the windward side of the platforms, air temperature on Platform X was 2 degrees higher than when the station buildings were absent. Air? temperature on platforms VII to IX increased progressively, and the maximum air temperature on platform VIII was 3 K higher than if station buildings were absent.

Railroad a field of basic industries in Korea had developed as representative transportation means in the interior. But since the 1970s, its transport requirement decrease had influenced in reduced earning. Thus railroad try to find a various subsidiary earning creations. Among the various subsidiary earning creations, a plan of privately financed station buildings is constructing and using. For the mean time the privately financed station have been constructed by in a narrow sensible development. But now like a Yongsan areas surrounding stations development, comprehensive development think over surrounding stations in a wide sensible development. Yeongdeungpo Station the traffic center of the south part in Seoul had been constructed by privately financed station of Lotte Shopping Co. after 1987. Yeongdeungpo Station constructed station building is a successful example for profitable. The successful instance of Yeongdeungpo privately financed station investigates and devises comprehensive development as thinking over surrounding stations for more and more benefits.

In this study, the characteristics of site amplification at seismic observation stations in Japan were estimated using the attenuation relationship of each station's response spectrum. Ground motion records observed after 32 earthquakes were employed to construct the attenuation relationship. The station correction factor at each KiK-net station was compared to the transfer functions between the base rock and the surface. For each station, the plot of the station correction factor versus the period was similar in shape to the graphs of the transfer function (amplitude ratio versus period). Therefore, the station correction factors are effective for evaluating site amplifications considering the period of ground shaking. In addition, the station correction factors were evaluated with respect to the average shear wave velocities using a geographic information system (GIS) dataset. Lastly, the site amplifications for specific periods were estimated throughout Japan.

This study analyzed the electric vehicle recharging station status with recharging time limitation due to long waiting time, and figured out the user status by user interviews. And then this study verified the validity of hypothesis in terms of environmental design perspective and suggested layout of recharging station model. 21 recharging stations in Korea and station operation cases of 7 countries were examined. Except for the USA, the reality of electric vehicle recharging station today is the 1st proving stage focusing on the infrastructure construction of electric vehicle recharging station. It focuses on performance of recharging facility, use efficiency and operation environment of electric vehicle. About the effective waiting time of the user to use it should be studied. The current conditions of recharging station are as follows: Lack of independent recharging space, lack of facility that reduces external effect of recharging space, and lack of lounge for users during the waiting time. These three are essential factors constructing a suggesting model after basic layout, which needs proper measurement on the long recharging time and long waiting time. The essential factors are applied to electric vehicle recharging station layout so that users might use 'digital refresh" i.e. lounge and information contents service during the waiting time which provides convenience of recharging and emotional space with users. Such upgrade recharging station environmental model might resolve the burden of long recharging time which may contribute to the popularization of electric vehicles.

수도권 지하철의 경우 역사의 규모, 역간 거리가 짧으며, 수요가 첨두시에 집중되는 경우는 선구 시격(Line Headway)보다는 역사 시격(Station Headway)이 선로 용량(Line Capacity)산 정시에 적용되는 시격이다. 역사 시격을 결정하는 요소들은 기계의 고정 값과 정차 시간이 있다. 다른 요소들은 이미 정해지거나 고정적인 값들이지만 수요에 따라 변화하는 정차 시간은 역사 시격에 가장 큰 영향을 준다. 본 연구에서는 역사 시격에 영향을 주는 요소들을 분석 후 수요에 따라 변화하는 정차 시간 예측 모형 식을 도출하였다.
