As far as recent investment in railway, disused railway yards is increased in each line and region. As a result, the interest of the related local government and agencies has increased on utilizing disused railway yards. In this study, we investigated the status of the disused railway yards and conducted legal review on the use of disused railway yards. In addition, we analyzed the disused railway yards use practices through case analysis and also suggested plans to diversify the ways of their usage.

친환경 교통수단인 철도에 대한 투자비중이 증가함에 따라 철도 고속화와 복선화 및 선형개량 사업, 철도노선의 교외지역 이설 등으로 폐선부지가 급속히 증가하고 있는 추세이다. 그러나 철도폐선부지가 방치되어 도시미관을 저해하는 문제가 발생됨에 따라 최근 지자체에서는 철도폐선부지의 활용방안을 모색하고 있다. 또한, 국토교통부는 "철도유휴부지 활용지침"을 제정하여 보전 활용 기타부지 등 3가지 유형으로 분류하여, 폐선부지를 체계적으로 활용하고자 하였다. 그러나 현재 활용 중인 폐선부지는 공원, 레일바이크, 자전거도로, 태양광사업 등으로만 활용되고 있으며, 폐선부지의 다각화 및 사후평가에 대한 연구가 부재한 실정이다. 본 연구에서는 국내외 폐선부지의 활용사례를 조사하고 전국 철도폐선부지를 대상으로 자연문화경관, 교육과학적 가치, 위치 및 접근성, 휴양 유발성, 개발여건 등 영향요인을 분석하여 정량적으로 평가할 수 있는 방법을 제안하였고, 이를 통해 철도폐선부지의 활용 다각화 방안을 모색하고자 하였다.

Unlike conventional transmission and distribution lines, catenary system for operating electric railway vehicles are composed of multi-conductor groups (feeder line, contact wire, messenger wire, protection wire) and are used for railway employees, public or passengers in the station yards. Electric shock hazards are exposed and electric shocks such as death or serious injury are occurring in electric railway vehicles, railway high-voltage distribution lines, and catenary system. In order to analyze the types of electric shock accidents on railway by systematic approach method, we modeled 'unsafe behavior classification' method using swiss cheese model. Based on this method, we derived the type of electric shock accidents about railway accidents during the last 5 years by analyzing the frequency of occurrence of human errors and unsafe acts, laws and regulations related to violations, and so on.

항만구역에 있는 철도시설 중에서 비교적 규모화 된 항만철송장은 현재 부산항지역과 광양항지역에 배치되어 있다. 항만철송장은 철도물류의 시종 역할을 하는 주요한 기능이나 현재는 선로 배선 규모, 하치장 면적 등에 있어서 철도의 특성을 반영하지 못하여 비교적 활성화 되지 못한 상황이다. 또한, 활성화 되어 있더라도 이미 처리용량이 포화상태에 이르러 더 이상 철도수송물량을 증대하기는 어려운 상황으로 철도컨테이너 수송사업 활성화를 위해선 근본적으로 항만철송장 시설규모에 대한 재산정이 매우 필요한 상황이다. 본 연구에서는 이러한 철송장의 시설배치 상 문제점 해결을 위해서 최근 개장한 부산신항의 철송장을 중심으로 문제점을 분석하고 해결할 수 있는 방안에 대해 살펴보았다.

The train ferry, accommodating trains roll on and off, is often called as 'Railway on the Sea' or 'Blue High-way' since she can connect the railways or roads segregated by the sea and improve the accessibility and continuity of land transport systems. The ferry is especially appropriate to the intermodal transport routes mostly passing through the land but have relatively short sea segment. As the train ferry can considerably reduce the cost and time for cargo handling and modal shift and unnecessitates excessive initial investment on infrastructures such as large harbor cranes or vast container yards, introduction of train Ro-Ro ferries lessen the total transport cost for door-to-door transportation with full exploitation of the existing railway system. All the ports placed in Shandong, Liaoning and Jiangsu provinces of China are connected to the hinterlands via well developed railway and road systems. Therefore, realization of the Incheon-Yantai train ferry system will link Korea railways to TCR and the 4,131-kilometer-long Longhai-Lanxin Railway, along the famous Eurasian Continental Bridge. In the present paper, the Incheon-Yantai train ferry will be introduced as a good example of an efficient multimodal short sea shipping system for Northeast Asia.

In large station with high density traffic, trains can be hardly controlled by CTC but by station dispatcher because CTC has difficulties in monitoring all states of affairs happening within each station such as departures, arrivals of many trains from different lines and shunting of trains to move between yards and platforms, etc. Therefore the station's dispatcher has to make quick decision about how to reschedule the times and routes for all the trains scheduled within a specific time window. And such decision becomes harder when an unexpected delay occurs because a delay occurring in a train propagates other trains as time goes on. Generally, it is called the conflict detection and resolution to adjust beforehand the distorted schedule due to a delay to original schedule. Our research is different from the state of the arts in that ours determines simultaneously the routes and the times of arrival and departure of trains, although others do only the arrival and departure time of the trains without considering the alternative routes and shunting of the station. This study suggests a mathematical approach for how to detect in advance and resolve efficiently the conflicts occurring within a station and it will be shown how to reduce delay using our approach by means of analysing the schedule of ChyungRyangRi station.

In this study, the evaluation for utilization of waste landfill was performed by field test to use waste landfill as construction site(Nangido in Seoul). The site where dynamic compaction test was carried out was divided by 4 yards. Yard 1, 2 were not eliminated widening of cover soil and Yard 3, 4 were eliminated it. Dynamic Compaction Pilot Test was carried out by the 15ton heavy tamper with drop height of 20m in Yard 1, 3 and with drop height of 15m in Yard 2, 4 We evaluated the compaction ability, optimum compaction number and noiseㆍvibration through field test, monitoring. To make use of waste landfill as a construction site, The dynamic compaction method is suitable for using in waste landfill as a construction site among the ground improvement methods.

And such decisions become harder when an unexpected delay occurs. This study suggests a mathematical model and algorithm about how to detect in advance and resolve efficiently the conflicts occurring within a station and it will be shown how to reduce delay using our approach by means of analysing the schedule of ChyungRyangRi station.

교토의정서 및 발리로드맵 이후 우리나라도 2013년부터 온실가스배출감축대상국에 포함될 예정임에 따라 친환경물류에 대한 정부차원의 대책마련도 시급한 상황이다. 본 연구는 이러한 정부차원의 친환경 녹색성장 정책에 맞춰 가장 친환경적인 철도물류 및 복합운송에 대한 활성화를 본격 연구하게 되었다. 본 연구에서 나타난 의왕ICD 터미널 내 철도물류시설의 주요 문제점으로는 하치장 부족, 공용 CY 비활성화, 비주주사 이용불편 등으로 나타나고 있으며, 철도물류시설의 주요 개선방안으로는 하치장의 추가 확장, 공용CY 활성화를 위한 철도공사 직영 및 상시하역체계 구축 조성 등의 철도물류시설개선이 필요한 것으로 나타났다. 이러한 철도물류시설의 개선은 철도공사 또는 업체의 노력으로만 해결될 수 있는 사안은 아니다. 철도물류시설과 복합화물 터미널은 대규모의 투자자금이 필요한 시설이며 사회간접자본(SOC)성격이 강하므로 민간차원에서 개선하는 데에는 한계가 있으므로 정부차원에서 보다 적극적인 개선방안을 모색할 필요가 있다. 이러한 정부차원의 철도물류시설 개선은 친환경녹색물류에 대한 지원정책으로 물류정책기본법에 의해 지원이 가능하므로 세부적인 지침 등을 마련하여 복합화물터미널이 근본적으로 활성화 될 수 있는 계기가 마련되어야 할 것이다.
