도시철도 운용기관은 관제센터를 중심으로 하는 1:N 기반 일제방송 시스템을 통해 철도 이용에 관한 다양한 정보를 고객에게 제공하고 있다. 하지만 이러한 일제방송 시스템은 설비 노후화 및 모바일 서비스에 익숙해진 도시철도 이용고객의 Needs를 충족 시키는데 많은 한계를 갖는다. 본 연구는 이러한 한계를 극복하는, 도시철도 이용고객의 위치정보를 활용한 모바일 기반 일제방송 서비스 및 이와 관련된 도시철도 이용(예정)고객, 운용기관, 외부 서비스 제공자 등 다양한 이해관계자의 요구사항을 분석하고 이에 관한 서비스 모델과 물리적 구조를 제시하였다. 이를 통해 재난상황 발생 시 신속하고 효율적인 상황 전파를 통한 도시철도 안전운행 확보 및 재난대응성 향상을 도모한다.

A railway station is a place where the railway operator concretize his marketing policy to meet the internal and external changes of a railway. Hence the analysis on the railway stations could give some useful information on the conditions which influence the shape of railway station. The purpose of this study is to analyze the development of Japanese railway stations. This study shows that the influencing factors on the shape of Japanese railway stations are as follows: invitation of investment from outside the japanese railway, necessity to define measures against the cut off the urban fabric by the railway facilities, profitability of the railway operator by the creation of subsidiary business, integration of administrative or public function into the station building. And the future of Japanese railway stations is now preparing by the policies on the accessibility and commodity of users and by the research projects on the environmental quality, user satisfaction.

Railway stations are functional buildings. Their primarily role is to help passengers or freights complete their trip safely, easily, comfortably, and to improve the railway operating system. However, some urban stations are lately taking the form of what is called a station complex, and some regional stations are being constructed together with local public facilities. Roles of railway station are changing. Therefore, meeting user, railway operator, local resident, and government needs, roles of railway station would include multi-functional complex, high quality terminal, community center.

Most surveillance systems of urban transit are based on CCTV(Closed Circuit Television). However, there is limitation that the passive monitoring system using CCTV in urban transit surveillance system to monitor massive environment applies thousands of cameras and it depends on operator's instinctive judgement whether it happens an accident or disaster. Urban transit operation corporations try to introduce the intelligent technology to overcome these problems as mentioned above. The intelligent system can be organized various ways and made configuration for purpose and function. In this paper, we describe the configuration problems of the existing surveillance system and propose the proper intelligent system configuration for urban transit We expect that the proposed configurations are very helpful to introduce the intelligent technology for urban transit surveillance system.

It is a proven fact with the opening of the Seoul metro line number 1 in 1974 traffic congestion on the roads has decreased and the efficiency of people transportation in general has greatly been enhanced in the downtown and surrounding areas of Seoul. Even today construction of new subway lines are under way and many more are being planned due to the easy access to stations, short waiting and average travel times, compared with personal vehicles, contributing to the efficiency of the public transportation systems that are linking the downtown areas and also the intercity systems in moving passengers during rush hour and times of special event. Since the labour costs of the train operator in any large city based subway system accounts for a major part of the operating costs per kilometer and to ensure cost efficient operations, especially during non-peak hours, it is necessary to implement an unmanned(auto-driven) subway system. In order to implement such a system it is imperative that the on-board and wayside signalling control systems be fully automated as well. Only through proper examination of safety procedures not only by the AUGT(Automated Urban Guided Transport)system but also by ail the international standards organizations involved can safely and stability be ensured.

Urban railway system that leads the urban public transportation enables the passengers to use the subway system safely and conveniently by indicating the destination of, status of approach of and other information on train through Train Destination Equipment(TDE), which is one of the important passenger services. The existing system is composed of Host Station Equipment(HSE) and operator panel that receives necessary input on train information from Total Traffic Control System(TTC), Local Station Equipment(LSE) that controls Train Destination Indicator(TDI) installed at each station, and Train Destination Indicator that ultimately displays train information to the passengers using the train system. This study aims to realize stabilized and reliable announcement system for destination of train by considering processing procedure and method of expression of inputted information of the existing system of notification of announcement of destination of train that can be applied in the RFID, which is the base technology of USN for which service expansion is easy, and to realize system that considers interface with USN and expandability with other facilities in the future.

Urban railway system has make rapid progress ever since Seoul metro line No.1 was opened in 1974. Now, it is time to prepare system maintenance scheme and procedure that can be available even after 30 years from now. Especially, signaling system must be chosen with considering its life cycle since the system is categorized into electronic equipments. As for current signaling system, mechanical components such as relays has decreased while communication and S/W has integrated in order to implement its correct function. Therefore, it is required to establish system review and switch-over scheme with considering operational environment, maintenance system and an operator. In this paper, therefore, we analyzed various factors - technical, operational and economic - that have effect on system improvement so as to prevent making any mistakes on system improvement.

This paper presents a case study of PSD(Platform Screen Door) system assurance based on EN50126 life-cycle stage. By applying this system assurance, the accidents related to urban light transit railway especially that caused casualties could be reduced tremendously. This case study contributes significantly to the reliability, availability, maintainability and safety of the PSD system. Request For Proposal (RFP) of a rail road operator in which required by RAMS is prepared in which to ensure all system assurance activity and safety assessment are compulsory. The step-by-step activities and related deliverables are used which include functional analysis, FMECA, hazard identification analysis, system hazard analysis, maintainability analysis, FRACAS, and finally verification and validation of the system.

This paper is a feasibility study on the calculation of operating cost in regards to the overall operation following the completion of a number of LRT lines currently in progress. Owing to the absence of operating experience in driveless LRT system at home, the difficulties lie in the assumption of the optimal operating budget applying domestic real situation. Nevertheless, with 34 years of accumulated operating experience in heavy rail transit system, Seoul Metro, the nation's biggest urban rail transit operator, performs O&M consultancy services for several on-going projects along with every effort to acquire know-how where the appropriateness of the cost estimation as a required deliverable is reviewed and a more efficient way is provided. The main focus of this study is to seek a method to calculate the optimal amount of operating expenses as well as a cost-effective alternative for possible weaknesses from the standpoint of the operator. The body of this paper discusses the five issues such as personnel cost, overhead, maintenance cost, additional purchase price, alternative investment fee from a more macroscopic point of view, and the conclusion deals with the adequacy of the reason for selection of institutions with various operating know-how.
