  • Urban transit is one of the most effective ways for efficient operation and construction of an urban transit by composition system which is liked originally such as rolling-stock, power, signal and infrastructure. Urban rail transit system is running in domestic, imports major equipments from advanced countries and setup for maintenance. But it takes long time because it does each organizations and lines. Also, signal, power and track system apply different standard by each construction organizations it causes an increasing construction of cost accordingly it desperately needs a systematic countermeasure. Therefore standard specification of urban transit have been establishing and operatingfor efficient operation of urban transit and base technology security that is populace ride to become a base of state economy. After track, power and signal system will be announced. Standard specification become more, the importance of administrationof standards is emphasized more. Specification administrator’s the importance which use a computing support tool recently in railroad part in embossed and is predicted to be more such forward. Therefore we propose the effective method of management with track, power signal system by constructed data-base system.

  • 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.

  • 도시철도와 버스는 대표적인 대중교통 시스템이며, 서로 공생하기도 하며 서로 경쟁하기도 한다. 즉, 경쟁적인 대중교통 시스템의 추가로 인해 전체 대중교통 수요가 증가할 가능성과 경쟁 시스템으로의 수요 전환 수준에 머물 가능성도 존재한다. 본 연구의 목적은 경쟁적인 대중교통 시스템이 존재하는 도시에 추가 경쟁 노선을 도입한 경우, 대중교통 통행량의 변화를 분석하는 것이다. 이를 위해, 도시철도와 버스라는 2개의 대중교통 시스템이 존재하는 대구시에 도시철도 3호선의 도입 전·후에 대한 대중교통 통행 변화를 분석하였다. 정확한 분석을 위해, 2015, 2016, 2019년 4월 두 번째주 1주일간 교통카드 빅 데이터를 수집하여 활용하였다. 분석 결과, 기존 도시철도의 추가적인 개통으로 철도망 확장에 따른 통행량 증대는 있었으나 대중교통 전체 통행량 변화는 미미한 것으로 나타났다. 즉, 기존 버스 통행량이 도시철도로 전환된 것으로 판단된다. 또한, 분석결과를 활용하여 단순히 대중교통 노선의 추가가 아닌 대중교통 수요 증대를 다양한 정책적 제언을 제시하였다.

  • Urban rail transit offers target performance and function because various lower part system such as rolling-stock, signal, power and trackis consisted as complex. In order to function properly an urban rail transit which is complicated system to work as safety and reliability, System must secure safety with structure, design, manufacture, install and verification and it is important to establish a safety standard follows it procedures, establish what step all it is important to operate. Safety standard of urban transit infrastructure is minimum standard necessary to secure safety of signal, power and track. Urban rail transit standard business leads to make many requirements. Recently, many types of equipment have applied to manage requirements and standards for system efficiently in part of universal, airline and car accordingly applied equipments use to manage a pursuit(Trace) between standard of system. Especially importance of management is emphasized more become more. Importance of standard management which usesa computing support tool recently in transit filed is embossed and is predicted to be more such forward. Therefore we propose the effective method of management with infrastructure system by constructed data-base system.

  • Most of the surveillance systems are based on CCTV, closed circuit Television. A surveillance system for urban transit is also based on CCTV. Urban transit operation corporations have a CCTV system and a lot of cameras to monitor the situation for the passengers, and the important facilities. But this system has some problems that it cannot respond to a state of emergency immediately. In this paper, we describe a configuration of an intelligent surveillance system for urban transit to solve that problems. Our proposed configuration include a camera with some intelligent module, and a processor to integrate various data from not only cameras, but also sensors such as a temperature sensor, a heat sensor, sound sensor and etc. and some other data generator. This system configuration can decide the state of the passengers and the facilities. The surveillance system with this configuration can available with the existing surveillance system without a considerable improvement.

  • Most of the urban transit operation company in Korea have a passive surveillance system to monitor the status of the passengers and facilities in the urban transit service area. The surveillance system is based on CCTV, closed circuit television, and several sensors, such as a fire sensor. However, this system has some limitations to prevent and cope with the emergency quickly. So the urban transit operation companies have plans to be change their surveillance system to be active. The active surveillance system has an intelligent function to detect the event predefined by managers automatically. To construct the active surveillance system, there are a standard concept design and a function analysis. In this paper, we propose the classification of the functions of the active surveillance system for urban transit. We divide the functions into five parts, ordinary monitoring, safety monitoring, environment monitoring, administration support, and record management. And we describe the systems related to the every functions to clarify the classified functions.
