High concentration of carbon dioxide at subway cabin is one of the serious environmental concerns because carbon dioxide causes drowsiness, headache, and nervelessness of passengers. Ministry of Environment set a guideline for indoor carbon dioxide levels in train or subway in 2007. In this study, a carbon dioxide removal system for subway cabin was developed and tested using a test subway cabin. Various types of modified zeolites were used as the adsorbent of carbon dioxide. The tested zeolites were applied to the subway cabin, and showed high potential to lower the indoor $CO_2$ level.

서울 도심의 인적 운송수단의 중심에 있는 지하철 $1{\sim}8$호선의 차량 객실조명과 지하철 역사 조명을 조사하여 현재의 조명환경을 파악한 후 각 호선별 지하철 차량의 객실 조도와 휘도를 측정하고 지하에 위치한 역사의 조도를 측정하여 분석하였다. 또한 역사의 기준등급을 환승역은 A등급, 일반역은 B 등급으로 적용하여 기준조도를 선정하였으며 현재의 측정 조도와 사용광원을 검토하여 에너지절약 및 지하철의 조명환경개선을 연구함으로써 이용객에게 쾌적하고 안락한 지하철 조명 환경을 만들고자 한다.

본 연구는 지하철 객실 화재시 배출가스나 연기에 의한 사망사고에 대해서 FDS(ver. 5.0) 사용코드를 이용해 객실내 화재의 유동현상을 검토한다. 시뮬레이션 모델로 인천메트로 송도연장선을 기준 모델로 설정하였으며 객차 화재발생시 측창문의 개방개소에 따른 배연능력을 검증하기 위하여 측창문 개방조건에 따른 배연특성을 시뮬레이션 하여 인체의 유해성 여부에 따른 위험성 평가에 대한 결과를 도출하였다. 본 연구결과는 지하철의 성능위주 설계를 적용한 기초자료로 활용됨으로써 지하공간 화재시 인명피해 최소화를 목표로 한다.

Subway is used as a useful transportation method to solve the metropolitan traffic problem for its advantages of being not only accurate, safe and massive, but also of not producing any exhaustion gas in compare with the other ground transportation systems. However, noise inside the car due to concrete based rail track and tunnel structure has become a social problem. So, an analysis on the noise characteristics according to their routes and locations was made on the basis of the actually measured results from the trial run. To reduce the interior noise of subway train, the side part of rolling stock should have a noise blocking system fur low band frequency noise, the floor of it should have that for medium range frequency noise and the side part as well as lower part of it should have good noise reduction and absorption function.

Information boards installed in Seoul subway stations are currently in four languages: Korean, English, Chinese, and Japanese. Informational announcements are provided to inform the main information or operation information through the LCD monitor installed in the train and in Korean. However, users are confused because the subway guide board screen displays advertisements more heavily than driving information As a research method, we grasped the current status and problems of the subway guide board installed on the Seoul subway, and presented an improved new subway guide board drafts. An online survey was conducted on 67 people, ranging from teens to 60s who mainly use the Seoul Metro. As a result of the study, the screen design is different for each boarding route, so it is necessary to unify the subway guide board that provides only necessary information. In particular, since the user transfers the subway several times in order to move from place to place, the subway guide board design should function as an emergency disaster guide or boarding information, not an advertising signboard.
