  • Tins paper is designed (ⅰ) to envisage the characteristics of high speed rail stations that will be in operation when the Seoul-Pusan line currently under construction is completed and (ⅱ) to assist policy makers in mapping out transportation strategies by providing insights into how advanced countries have handled problems under similar circumstances. Ultimately, tins paper intends to present alternatives of trans-modal systems in an attempt to set a direction for future policy making in the high speed rail sector. The alternatives recommended in tins report stress two important elements for maximized utility of high speed rail: One is to maintain consistency in transportation policies and the other is to attract consumers to the station areas.

  • 환승은 대중교통의 대표적인 취약점으로 꼽히는 불편함으로, 대중교통의 경쟁력을 약화시키는 요소이다. 이에 환승으로 인한 불편함 중 개선가능한 요소들을 체계적이고 효과적으로 개선하기 위하여 환승시설 및 환승체계의 물리적 요소들에 대한 보행자 편의성을 계량화하여 환승역사의 환승 편의성에 대한 객관적 평가기준을 마련하고자 한다. 본 연구는 특히 KTX 역사 및 철도 역사를 대상으로 지역간 통행에 있어서 환승역사의 물리적 특성이 환승수단의 선택에 미치는 영향을 파악하고 그 과정에서 환승저항 모형을 구축하였다. 또한 이를 바탕으로 국내 주요 KTX역사 및 철도역사 환승시설을 대상으로 환승저항값을 산정하여 비교하였다. KTX 역사와 철도역사의 물리적 요소들 중 환승 의사결정에 유의하게 영향을 미치는 요소는 환승패스의 외부보행거리, 환승패스의 내부보행거리, 계단 수, 에스컬레이터 수로 동일하게 나타났으나 환승저항 요소의 상대적 크기에 있어서는 차이가 있는 것으로 분석되었다. 에스컬레이터 1대는 약 1~3분의 체감시간 절감 효과를 가지는 것으로 나타났다. 산출된 환승저항 모형은 환승역사별 시설여건을 비교하고 시설개선의 우선순위를 판단하는 데에 객관적 지표로 활용될 수 있을 것이라 기대된다.

  • The rail surface irregularity is generated severely by train braking effect in the section of station. The braking force increases slip rate and friction factors caused by wheel-rail contact points. It brings rail surface irregularity as well. In this study, interactions between wheel and rail were investigated using rolling contact fatigue theory and mechanism of rail degradation through fracture mechanics. For the more, the Von-Mises stress occurred on the rail due to the interaction between wheel and rail was analyzed using 3-D finite element method. The amounts of surface irregularity of rail were measured according to accumulated passing tonnage in urban railway in fields. Therefore, the maintenance of rail should be separated by running and braking sections to prevent RCF defects.

  • 정부고속철도 건설계획이 1998년 IMF로 인하여 서울 시흥구간 및 대구$\sim$부산간은 기존 경부선을 이용하여 우선 개통하고, 2단계로 대구$\sim$부산구간을 신설 개통하는 것으로 변경됨에 따라 서울도심 입출구부인 서울$\sim$시흥구간은 고속열차, 일반열차 및 화물열차의 운용운행으로 일반열차 운행횟수 축소로 인한 서비스 저하, 고속철도 서비스 추가 어려움 등으로 동 구간의 신설확장에 대한 지속적인 필요성이 제기 되어 왔으며, 호남고속철도 또한 수서 출발을 위한 강남권 고속철도 건설계획이 경제성 등의 이유로 오송에서 분기하는 것으로 변경됨에 따라 강남권 및 경기남부지역 주민들의 고속철도 서비스혜택의 기회가 박탈되는 결과률 초래하였다. 경부고속철도 개통이후 국가교통체계가 고속철도 중심으로 변화하고 있고, 경부고속철도 2단계 개통, 경전선 및 전라선 복선전칠 완공, 2014년 호남고속철도 개통시 고속열차 추가수요가 발생하나, 서울$\sim$시흥구간의 선로용량 부족으로 고속열차 광명역 출발, 일반열차 운행횟수 축소 등의 파행적인 열차운영이 불가피하므로 이와 같은 문제점을 근본적으로 해소하기 위한 강북구간 (광명$\sim$화전) 의 선로확장과 더불어 강남구간 (수서$\sim$평택)의 고속철도 신설을 추진하여야 한다. 이에 따라 본 고찰에서는 수도권 고속철도 선로확충을 위한 효율적인 열차운영방안, 시설계획 등 고려 하여야 할 사항에 대하여 검토하고자 한다.

  • Station is an important building in high-speed railway, and its vibration and noise may significantly affect the comfort of waiting passengers. A coupling vibration model for train-structure system is established to analyze and evaluate the vibration level of a typical waiting hall under dynamic train load. The motion of a four-axle vehicle with two suspension system is modeled in multi-body dynamics with linear springs and dampers employed. The station is modeled as a whole finite element structure which is 113 m in longitudinal and 163.5 m in lateral, and the stiffness of the station foundation is considered. According to the assumptions that both wheel and rail are rigid bodies and keep contact to each other in vertical direction, and the wheel/rail interaction and displacement coordination in horizontal direction is defined by the simplified Kalker creep theory, the vehicle spatial vibration model has 27 degrees-of-freedom. An overall analysis procedure is made of the train moving through the station, by which the dynamic responses of the train and the station are calculated. According to the comparison between analysis and test results, the actual connection status between different parts of the station is estimated and the vibration level of the waiting hall is evaluated.

  • Dipped track profiles between rail transit stations can significantly reduce propulsive energy, braking energy and travel times. This work quantifies their potential benefits for circumstances reflected in various values for dips, speed and acceleration limits, station spacings, and available power. A deterministic simulation model has been developed to precisely estimate train motions and performance using basic equations for kinematics, resistance, power and braking. For a dip of 1% of station spacing, in which gradients never exceed 4%, our results show savings (compared with level tracks) exceeding 9% for propulsive energy, 15% for braking energy and 5% for travel time between stations.

  • This paper explored an effective scheduling method for the Seoul-Busan High Speed Rail. It is important to decide train frequency influencing on scheduling method. Main factors to decide train frequency are location of station, social economic index, land use of station area and travel demand. In this paper, we focused on travel demand which is critical factor to decide train frequency. And we studied on standardized scheduling method. Simulation method is used to analyze the performance of explored method.

  • A track-circuit device exploits two rails as a conductor of an electrical circuit. It detects the presence or absence of the trains with variation of received level when wheel sets of the train shunt rails together. So, it plays an important role in train operation. Non-insulated audio frequency(AF) track-circuit device can separate the rails into tracks by insulated joints without physically cutting the rails. And it transmits AF signals at track boundary, of which frequency is different between adjacent tracks. It has been employed at station-to-station section of domestic high speed rail, general rail, and subway. But It was not used at station yard of complicated general railway where lots of branches exist. In this paper, we consider current development status of non-insulated AF track-circuit device for the use of station yard.

  • This paper explored train frequency of intercity rail station. Main factors to decide train frequency are location of station, social-economic index and land use of station area and travel demand. In this paper, we focused on travel demand which is critical factor to decide train frequency. Tests on a KTX case show that train frequency can be efficiently decreased in weekday to transport same demand. The work has shown many subjects that need further research. It is important to include various factors influencing on train frequency decision.

  • In this study, we have studied rail infrastructure related to emergency action to manage the risk when emergency caused by faults of facility or rail vehicle during operation happens. Especially we have compared the effect of emergency action with examining the structure of vehicle, tunnel, bridge and access road, etc which are related to emergency action. Also, we have tried to analyze effects of radio and communication equipment, lifesaving and refuge which could be used for rolling stock, station, control room, tunnel, bridge and etc, and we have presented the way of reporting the emergency to the train driver or crew, control room, outside networks which could be used by passengers in vehicle, station, railroad line. Based on these, we have analyzed the conduct of emergency action in length of time when emergency happens in railway and high-speed railway, and studied the method of which passengers could be guided safely and escape from the scene of the accident.
