This study shows that access to urban railway station affects the development of railway station's surrounding zone (RSSZ). For instance, the value of the property in RSSZ is likely to rise on the basis of the before and after the opening of a urban railway. Urban railway system is believed as an important solution to resolve worsening transport problems in metropolitan city. Also, the opening of a urban railway line is expected to affect the change of urban spatial structure, and to have more influence on land price of RSSZ.

국내 도시철도분야의 정보화는 제품설계부분과 운영/유지보수 분야에 일부 전산화가 이루어져 있으나, 정보의 체계적인 관리 및 표준화가 되지 않아 정보의 효율적인 이용 및 통합관리가 제대로 이루어지지 않고 있다. 본 연구는 국내 도시철도 정보화 분야를 세계적인 경쟁력을 가진 분야로 육성하고 수명주기비용(Life Cycle Cost)을 최소화하여 경제성을 극대화 시킨 도시철도 정비유지체계 정보화 시스템을 개발하기 위한 것이다.

도시철도유지보수체계 정보화시스템 연구에서 예방정비시스템 구축을 위해 RCM 연구를 진행하고 있으며, 특히 예방정비에서 RCM은 지난 십 수년간 정비보수(Maintenance) 분야의 관리 기법으로 다른 어느 분야의 관리 기법 보다 한층 탁월한 발전을 하고 있다. 특히, 도시철도분야는 매우 복잡한 시스템으로 유지보수에 대한 신뢰성과 효율성 및 안전성을 가장 먼저 확보하여야 한다. 이를 위해서 본 논문에서는 여러 분야에서 오랜 기간동안 운영한 결과 상당한 유익점이 있다고 증명된 신뢰도 중심 정비 (Reliability Centered Maintenance: RCM)에 대한 소개를 하면서 도시철도 시스템에 대한 적용하고자 한다.

When the electric motor car was first introduced, an engineer, responsible for the work related to operation and a conductor for the announcement and management of entrances and the other services like as monitoring the passengers in the platforms used to take together the train for passengers' safe. As new technologies developed and the urban transit system had the automatic driving facilities, automatic door switch and broadcasting systems, to solve the financial problems, most subway systems introduced the one-man operation system. To curtail the operating expense through automatic control and operation for the economical efficiency, the crewless driving system was introduced abroad around 1970 on the light weight train and Japan started the crewless driving system in 2005, Germany started it in June 2008. We examine system requirements of the system and methods to construct safe systems that would be introduced, suitable for one-man operation system or crewless driving system through the surveys and analysis of driving state and the systems.

Passenger safety is a primary concern of railway system but, it has been urgent issue that dozens of people are killed every year when they fall off from train platforms. Recently, advancements in IT have enabled applying vision sensors to railway environments, such as CCTV and various camera sensors. The objective of this work is to propose technical and system requirements for establishing intelligent monitoring system using camera equipments in urban transit system. We suppose the system is to determine automatically and in real-time whether anyone or anything is in monitoring area. To achieve the goal, we analyze recent image processing technologies for detection and recognition, and suggest possible direction of system development for applying urban transit system. According to the results, we expect the proposed system requirements will playa key role for establishing highly intelligent monitoring system in railway.

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.

Recently, with expansion and advent of the wire&wireless networks has been set up by various heterogeneous networks in urban transit networks. It's focussing on an interworking technology. As same as way, In a subway & railway monitoring system networks has been set up by various heterogeneous technologies such as IEEE802.11 WLAN, IEEE802.15 WPAN, DVBT, UWB, BinaryCDMA, ZigBee. These heterogeneous technologies is deeply investigating for the purpose of interworking and easy control as a research area. In this paper, we propose using VoiceXML based of XML for ensure interworking within heterogeneous subway & railway networks. Therefore It will be provide service for staff who has moving and anywhere, anytime in outside. Eventually, we expect that confirm efficiency of effective system through this study.
