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 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.

The financial incomes of urban rail transit authorities have been only from the fares. In order to increase the customers and expand the scope of enterprise, it is the most feasible mean to develop the area around the stations. Current experiences have confronted the excessive concentration of population and traffic congestion due to the lack of systematic planning and the excessive focus on the business. This study reviewed the necessity of the impact area around the urban rail transit stations by the organizational analysis for the urban rail transit authorities, and reviewed domestic/foreign cases. Finally, This study suggested the strategy for the development of impact area around the urban rail transit stations.

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.

It is expected that standardization framework for urban rail transit system will contribute to more convenient and safe traffic service and ensure higher reliability and availability of urban rail transit rolling stock and infrastructure. Since 1995, Korea Railroad Research Institute has been performing the project for standardization and development of urban rail transit technology to improve performance, safety and operational efficiency. Communication system in urban rail transit consists of various subsystems, such as radio communication system, digital transmission system, integrated monitoring system and broadcasting system and its standardization will be implemented based on these subsystem. Broadcasting system is to provide information related to operation and emergency to passengers and operators. In this paper, we suggest standardization scheme for urban rail transit broadcasting system through analysis on present state of the system.

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.

The safety of staff, customers and of general Public in general viewed as one of the most important requirements in the urban transit. The maintenance computerization system for car of urban transit is a part of standardization and development of urban transit system, and We have been performed the establishment of maintenance computerization system from 2001 to 2005. The RAMS (reliability, availability, maintainability and safety) estimation for maintenance computerization system are utilized in a variety of computerization system for user's convenience and safety in maintenance. Ever since its inception though, the urban transit has searched for ways to improve reliability, availability, maintainability and safety of the railway subsystem. Provision of a reliable maintenance system include RAMS of the vehicles plays a very important role in achieving a safe system.

Propelled urban rail transit EMU's standardization/localization business receiving MOCT's assistance for 2001 years since 1995 in KRRI. But. urban rail transit is operated because signaling. electrical power. rail etc. as well as EMU connects each other. Therefore, receive MOCT's assistance since 2001 and is achieving standardization research about urban rail transit's infrastructure including signaling. Specially, is propelling standardization about CBTC way for expansive standardization hereafter in signaling part. Main contents of this urban rail transit's signaling standardization research are as following. - standard specification creation - development of core equipment for standardization specification verification - standard specification completion by core equipment testing & evaluation Is explaining about establishment of scheme and these contents for this urban rail transit's signaling's standard specification creation in this paper.

We need to make the standards of maintenance information for urban transit to reduce the cost to maintain the information and to share the information with maintenance workers. It is enable to do systematic maintenance for urban transit by using the information system based on the standardized information. In this paper we propose the major items to standardize and the methods to lay out the standard schemes to enable structured maintenance. We present the 4 items, bill of material, material classification, accident/fault classification, electronic document, to standardize. And we propose how to implement the information system for urban transit based on the standardized information. We describe the implemented information system in two parts; a rolling-stock and an infrastructure part. And also we describe the result of survey to evaluate the system installed at Seoul Metro and Seoul Metropolitan Rapid Transit.
