  • 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.

  • 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.

  • 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.

  • 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 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.

  • Urban transit operation is to manipulate the vehicle or train of urban transit to be operated on the basis of the installations such as track, power, communication, signaling and so on. It can be performed by manual or automated, or manned or manless operation considering its system built, operation efficiency, safety, etc. Because of the heavy impact directly to the safety of passenger transport, it has been managed strictly by the Regulation for Train Operation of Urban Transit according to Urban Transit Act. However, the present regulation has been basis of the manual operation mainly, it is crossing beyond the limitation of application to the manless operation which is being introduced moment to moment. It is needed increasingly to revise the regulation for the manless operation which is close at hand now. In this paper, we examined and analysed the cases of manless operation of urban transit planed within the country such as Busan 4th Line, Shinbundang Line, Busan-Kimhae Line, etc. based on the present regulation, and proposed the review of considerations to reflec the manless operation to the regulation to be revised.

  • This paper presents an intersection of technologies of ITS (intelligent transport systems) and CBTC(communication based train control) in urban transit system. ITS is based on Information and communication technologies. And also these techniques are fundamental for railway system. ITS has some technologies useful in railways such as traveler information service, public transportation information service, and advanced vehicle control Systems. Therefore, both systems need to technological cooperation. In this paper, we proposed useful an cooperation method for both systems.

  • 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.
