This paper discusses the development of a generic train operation model from a set of Korean Urban Transit Regulations such as Regulation for Train Operation of Urban Transit, Regulation for Safety Requirements of Urban Transit and so on. It is to communicate with various stakeholders on urban transit system, and to elicit copious requirements in performance of the urban transit train operation based on the model.

Most urban transit companies recognize the necessity of classification for facility management Classification for urban transit facility is necessary for standardization of maintenance management. The practical application. however. is not easy because of the absence of standardization of classification for urban transit facility and the difficulty in objectification of breakdown structure. This study suggests a proposal of classification for maintenance management in urban transit facility. This study defines standardization of classification as facility, work, maintenance and attribute to manage urban transit facility. And attribute classification consist of material, equipment and document. The suggested classification can be used as a useful maintenance management tool that enables evaluation of urban transit facility by standardization. The results of this study could be used as references for related urban transit companies.

Urban transit, which takes an important role of traffic volume, is operated in four different urban communities and constructed in two urban communities. However, the urban transit of each communities has different system in operation and construction. It is not efficient to construct and operate. Furthermore, is difficult to maintain urban transit system. In this paper, the standardization of power supply system for urban transit has been performed to solve above problems.

최근 우리나라에서는 도시공간구조를 자동차 중심형 에너지 다소비형에서 대중교통과 보행을 우선하는 형태로 재편하여 대중교통이용자의 편의를 도모하는 동시에 에너지소비를 줄이려는 노력이 확대되고 있다. 우리나라의 도시는 미국과 유럽의 도시들에 비해 상대적으로 고밀로 개발되어 있고 대중교통서비스도 상대적으로 양호하여 대중교통중심형 도시구조로의 발전 잠재력은 매우 높다고 할 수 있다. 그러나 현재 우리나라의 도시들은 선진국의 주요도시들에 비해 대중교통수송분담률이 낮고 도시환경의 질도 상대적으로 낮다. 본 연구의 목적은 우리나라 도시들이 대중교통중심형 도시로 탈바꿈하기 위하여 풀어 나가야 할 도시구조상의 문제가 무엇인지 분석하는데 있다. 이를 위해 본 연구에서는 수도권 내에 위치한 대중교통결절점을 중심으로 실태를 조사하여 토지이용밀도, 토지이용복합성, 보행편의성, 대중교통연계 측면에서의 문제점을 분석하였다. 또한 분석 결과를 토대로 우리나라 도시들이 대중교통중심형 도시공간구조로 전환되기 위한 도시계획 측면의 개선방향을 제시하고자 한다.

The transport system and its infrastructure are not only the fundamental means of sustaining the operation of contemporary cities, but also important drivers for the evolution of urban form. Rail transit, critical to improving the operational efficiency and optimizing the spatial layout in cities, is one of the critical conditions for high-density areas with limited land and concentrated resources to be compact to take on complex challenges. As a node element of infrastructure, rail transit entrances are the most important points connecting the rail transit system with urban space. Although influenced by urban form, their quantity and location also influence and shape the evolution of urban space form. Based on the development gap of high-density areas in various contexts, focusing on various rail transit stations in Asia, this research analyzes the correlation between rail transit entrances and peripheral high-density urban form in a delicate, dynamic and granular way. The research considers both horizontal and vertical perspectives, in combination with the urban evolution process in time series, to explore the development trend of high-density urban form in Asia from the aspect of correlation, and building a new foundation for research on urban form, suitable for different types of cities.

It is very important that reduce the maintenance cost and extend life time of the urban transit EMU through effective maintenance method research. The maintenance cost of the urban transit EMU shares 60%~70% of it's life cycle cost. It means that the maintenance cost is bigger than the introduction cost of the urban transit EMU. In this study, I introduces a quality control technique to improve the urban transit vehicle reliability. I suggest the control chart using quality control technique. And the control charts apply to the Static Inverter of EMU.

The standardization system in Urban Transit is the system that verifies and develop the standard, a safety standard, a performance test standard and a Quality certification standard to improve the capability, the safety and operational efficiency and that develops technologies of the main installations. We have already developed a signal, electric power in Urban Transit. Also, we have already noticed the standardization of railroad tracks and developed the main installations through the first stage in the standardization in 1995${\sim}$2006. Still, there remains many fields to standardize, like information and communication facilities, facilities in the station, governmental organizations and maintenance facilities because, Urban Transit is so widespread. In case that we do not keep promoting the standardization in Urban Transit, rather it could hamper development of the Urban Transit. So, it is important to maintain and advance the standardization in Urban Transit. In this paper, we suggest the research course that we would promote, to maintain and develop the standardization in Urban Transit.

The one of the necessary technologies to live in the ubiquitous society that we can exchange some informations whenever it is and wherever we are, is the technology of context-awareness. The technology of context-awareness can be used various fields-medical science, national defense, national security and etc. and the technology can affect our society by and large. The technology of context-awareness is also applicable to many fields in the urban transit. In this paper, we describe the present condition of the technology of context-awareness and the examples of practical application of it and suggest some plans that are applicable to build an intelligent surveillance system for urban transit. We can connect the operating officer who is in the nearest to the place where the some events happened within the urban transit service area through the intelligent surveillance system for urban transit and we can eel a foothold in perceiving automatically various events within urban transit service area. So, the technology of context-awareness is the basic technology to realize an intelligent surveillance for urban transit, for the security of passengers and the protection of facilities in urban transit.

The purpose of this study is to analyze death injuries and operation troubles of urban transit. No difference was shown in death rates between Line 1 of Pusan urban transit and Line 5, 7, And 8 of Seoul metropolitan transit. And relief time by another train did not depend upon the number of crews. We concluded that thorough inspection and preventive maintenance of trains and facilities are necessary for safe and timely service of urban transit.
