경제적, 환경적 이유에서, 승용차 이용을 억제하고 대중교통수단 분담율을 제고하는 교통정책은 수도권 지자체에게 있어 매우 중요한 과제이다. 통행행태를 근본적으로 이해하는 것은 이러한 정책의 수립과 집행에 매우 중요한 필요조건이다. 소규모 샘플자료를 이용, 특정한 통행 행태와 몇몇의 사회경제적 혹은 지리공간적 변수들 간의 상관관계에 대한 횡단면적 분석을 행하는 것이 이 분야 전통적인 연구주제였다. 연구결과는 스냅샷과 유사한, 시공간적으로 제한된 정보만을 제공한다. 그러나, 통행은 공간적으로 상이한 장소에서 벌어지는 일상활동 참여로부터 파생되며, 일상 활동계획 상에서의 활동-통행 간 순서 관계는 통행 행태의 중요한 틀이다. 본 연구는 다차원 정보배열비교법과 핵심정보배열추출기법을 이용, 서울시민의 일일 대중교통 이용 자료인 스마트 카드 자료를 분석하여 서울시내 대중교통 이용 행태의 일반 특성을 탐구한다. 분석 결과 서울 강남/북 간 버스-전철 연계통행과 간선버스 통행간 통행 행태의 중요한 차이를 확인할 수 있었다. 즉 통행패턴은 보통 강북과 강남 권역 안에서 형성이 되어 있어, 자연 장애물인 한강을 건너 강남/북을 가로지르는 통행패턴은 상대적으로 적었다. 또한 강북과 강남 각각의 권역 안에서 CBD를 들르는 통행패턴은 보통 전철 혹은 지선버스-전철의 연계교통수단을 이용하는 데 반해 지선버스 혹은 간선버스만을 이용하는 통행패턴은 CBD가 아닌 지역으로 목적지가 국한되는 경향이 있다.

Maximum speed of the train could not exceed over 160km/h with R-bar system in the underground type tunnel structure. By the research to overcome this speed limit, maximum speed has reached up to 200~250km/h recently by new R-bar system. It is under discussion to construct Metro Express Line between Gyonggido and Seoul which requires maximum speed 180km/h~230km/h. New R-bar is an optimal system to achieve the speed improvement in this line. This study shows application of the high speed R-bar system in the underground tunnel section.

Recently, ubiquitous sensor network forms the self-organization network, and transfers the information among sensor nodes that have computing technology ability. In this paper, we design and implement U-IT system for monitoring the safety of metro railway and underground shopping malls. For this, we implement sensor nodes to support IEEE 802.15.4 wireless communication standard using low power. Also we implement USN gateway node system to transmit the collected data from sensor nodes to database server over CDMA cellular network.

The automatic/driverless operation which are great important techniques in metro railway are required to increase higher safety, greater reliability, and transport capacity. To satisfy such demands, we must have the system design and testing technique for the railway system operation. These techniques are related to the onboard train control and communication systems which include TCMS(Train Control and Monitoring System), ATO(Automatic Train Operation), ATC(Automatic Train Control), and TWC(Train to Wayside Communication). These sub-systems must be interfacing with not only each others but also the signal system on the ground. We tested the train control system on Test line that has been developed on the basis of the standardized type EMU for korea railway systems. This test line which is located in Sangju, have been constructed for testing 7 ＆ 8 line of Seoul Metro railway.

유비쿼터스 도시는 도시건설산업과 유비쿼터스 정보기술의 융합에 의해 이루어진다. 도시건설산업은 도시의 물리적 공간을 건설하는 분야로 점점 공용화, 통합화, 융합화 될 것이다. 지하시설물은 공동구를 활용하여 공용화하고, 지상시설물은 통합화가 가능한 시설들부터 통합화한 후 센서통신망이 발전하면 융합화시켜 지능화시킨다. 정보기술은 전산화를 지나 정보화를 이루었고, 유비쿼터스 정보화로 발전되고 있다. 이 논문은 유비쿼터스도시의 건설등에 관한 법률이 시행됨에 따라 도시공간과 유비쿼터스 기술의 융합화 방향을 설정하기 위한 논문이다.

Seoul Metro has been continuously growing after its foundation on August 15, 1974 and is currently acting the leading role in the city transportation which is now used by 4,130 thousand people (as of early 2011) on a daily average. The number of the electric rail cars also increased significantly from 60 cars at the time of foundation to 1,954. And the types of the cars also started and operated with the rheostatic control cars in the 70s to the chopper control cars in the 80s and VVVF control cars in the 90s. But the control devices of the driver's cabs haven't been accustomed to the drivers because of it's diversity. Therefore, This study carried out the survey for the preferences of control devices from the incumbent drivers at Seoul Metro. And we analyzed it and suggest a method for standardization of it's locating and naming the major control devices in the driver's cab as the consideration of their preference for it's efficiency, safety, and convenience.

Seoul Metro railway facilities' inspection and maintenance tasks cause failure analysis, but if there is trouble the diverse cause investigation and the systematic analysis and management among broken facilities, related facilities and components fell short and the conditions are different. And, excess and insufficiency, under inspection and maintenance, is being raised regardless of the introduction year and the operating environment including the number of use by applying the same facilities in the uniform inspection cycle. In this study, we will analysis systematically facility system information, failures, operational status, performance, fault and maintenance information resulting from the maintenance management of railway facilities and derive the relationship between associated equipment and its components. In addition, optimizing the inspection and the maintenance cycles of railway facilities, we will improve the reliability of operation. Considering the probability of risk, it is possible to predict the occurrence of accidents or faults and to minimize the frequency of breakdown by pre-inspection maintenance. Finally, This paper is to introduce the content of constructing the Seoul Metro RCM-based failure analysis system for railway facilities to support the optimal continuance of operation status of equipments and the securement of the safe operation of vehicles.
