구조물의 『3차원 설계』는 성공적인 BIM(building information modeling) 정착을 위한 핵심 기술이다. 이를 위해 다양한 BIM 라이브러리들이 개발되고 있지만 선형기반으로 구조물이 가설되는 교통 인프라의 설계업무에 적용하기에는 한계가 있다. 상용화된 BIM 소프트웨어들이 지원하는 라이브러리를 계획된 선형을 기반으로 구조물이 가설되는 교통 인프라의 설계 업무에 적용하는 것은 사용성 측면에서 한계가 있다. 더욱이 조합을 고려하지 않고 개발된 라이브러리로 생성된 모델은 다양한 설계변경 상황에 대응하기가 쉽지 않다. 따라서 본 논문에서는 교통인프라 구조물인 철도 교량을 대상으로, 유관 시설 또는 부재에 대한 3차원 객체를 설계변경에 효율적으로 대처할 수 있도록 매개변수 기법을 적용한 ‘BIM기반 3D 모델 생성 자동화 모듈’을 구축하였다. 모듈의 주요기능은 기준선형을 바탕으로 기준경로를 도출하고 다른 객체와의 조합을 고려하여 목표객체를 연장 및 배열하는 것이다. 또한 모듈의 조합으로 구성된 철도교량의 통합모델에 대하여 설계변수를 입력할 수 있는 사용자 인터페이스를 구성하여 설계변경 대응능력에 대한 적용성을 검증하였다.

철도교통은 기술적, 사회적, 문화적 환경의 변화 및 고속철도의 확장과 철도 구조개혁 등으로 현장에서의 인적요인으로 인한 오류가 증가로 안전을 위협하는 요소가 날로 증가하는 추세로 안전신뢰성 확보는 절대적이다. 따라서 인적오류를 근절하기 위한 안전시스템의 적정성 및 신뢰도에 대한 분석과 해외 선진철도의 안전정책 및 안전시스템의 변화와 발전 추세를 분석하여 국내 철도안전의 방향을 제시하고자 한다.

The load of a maglev train, which is being considered a future transportation, is uniformly loaded on a levitated surface of a rail unlike a typical train because the maglev train is magnetically levitated and propelled. In addition, the driving performance is superior since the maglev train doesn't directly contact the railway. A integrated track system, to which a sleeper is installed toward a longitudinal direction instead of a perpendicular direction, is suggested, considering this loading characteristic. The longitudinal sleeper of this system is expected to contribute to stiffness increase of a bridge and weight-reduction of a girder. In this study, the structural characteristics of proposed and typical systems have been numerically compared and analyzed. In addition, the improvement of the integrated system has been proposed.

The load of a magnetic railway is uniformly loaded on a levitated surface of the rail. So it is advantageous for noise and vibration compared to the typical railway systems. But for ensuring driving stability and ride-quality, regulation about the gap of rail is stricter than the typical railway. In this study, the impact of bracket, which can control the gap of rail at the integrated track system, have numerically been performed. Also, the effect of interval of the bracket installed in the longitudinal direction of the integrated track system, which consist of girder, bracket, sub rail and levitated rail, have been compared and analyzed. Through this, applicability of the bracket structure for integrated track system have been identified.

Advanced Safety Management System(SMS) of Korea Railroad Corporation for risk management should be established applying contents-centered domestic standard according to Railway Safety Act and process-centered international standards suggested by Lloyd's Register Company. Besides, laws, regulations, guidelines and manuals which are optimized for each sector should be systematically integrated to strengthen the consistency of SMS of KORAIL. New safety regulations and guidelines for safety management/train operations/maintenance should be established according to the safety policy of KORAIL to boost effective field work by regulations, guidelines, manuals, etc. The advanced Safety Management System will lead KORAIL as a competent global enterprise with its boosted reputation in the international railway market.

Recently, as change in global logistics environment, various issues have been presenting. These issues are including the pursuit of low cost-high added value, the realization of sustainable logistics system, the protection of environment, and the development of ubiquitous techniques. To cope with these environment changes and improve the national logistics system, the government have carried out various logistics policies and pushed ahead development of national logistics information network. But still, from a view-point of national logistics, there are several inefficient elements such as information connection and utilization, code/data standardization. In this paper, the survey result of global logistics environment change, logistics policy of a developed countries, domestic logistics policy and information system status will be presented. And from these status, suggestive points are mentioned. Finally the status of railway logistics information and future developments are presented.

This article addresses the question of how the operational architecture for a railway safety information system should be developed. A successful railway safety information system can be developed by fully reflecting the business process and needs at the enterprise level. To date, there has been minimal research effort towards the development of the operational architecture for a railway safety information system. To this end, a variety of enterprise architectures have been studied so far. In this paper, as an important guideline, DoDAF (Architecture Framework) is selected to be used in developing a railway safety information system. In particular, we propose a method to implement the operational architecture based on DoDAF.

It is very important to delivery timely and safely items in logistics. So, the home delivery service system is introduced by many enterprises. Also, the beginning in 1990's, the rapid increase of automobile increased logistics cost and led to road stagnation. So, the railway transportation use in logistics can be considered. The railway transportation in home delivery service system can overcome the limit of transportation by land. This study evaluate railway transportation in home delivery service system by economical efficiency and timeliness.

철도교의 장기변위 정보는 시공 및 유지관리에 있어 매우 유용하지만, 실구조물의 장기간에 걸쳐 발생하는 변위를 정확하게 계측하기 위해서는 많은 실질적인 문제를 해결해야 한다. 본 연구에서는 철도교량의 효과적인 장기변위 계측을 위해, 컴퓨터 비전 기반의 비접촉식 기법을 제안한다. 컴퓨터 비전 기반 기법은 비용적인 측면에서 우수하며 사용이 간편하여 최근 교량변위 계측을 위해 기술개발이 활발하게 되고 있으나, 카메라의 미소변위에 의해 큰 오차가 발생하므로, 장기변위의 계측에는 적합하지 않다. 본 연구에서는 두 개의 카메라를 이용하여 카메라 변위에 따른 오차를 보정하는 방식으로 장기변위 계측을 가능하게 하였다. 개발된 기법을 시공 중인 철도교량에 적용하여 성능을 검증하였다.

The GIS integrated monitoring and DB system was introduced.

The mechanical behavior of the fasting system on the clamping forces has not been fully studied because of structural complexity. The goal of this research is studying the effect of nonlinear of the rail fastening system on the clamping forces in the railway bridges. A numerical model is proposed to analyze the problem of fasteners. The model is conducted by using a code in FORTRAN. In this study, fasteners are modelled as springs. The calculated results show a good agreement with values referred from manufacturer. As a result, the numerical simulation is believed to indicate an approximate value of clamping force considering the nonlinear behavior of fastening system.

Needs for a new technologies of infrastructure systems arose, following the development of next generation EMU(Electric Multiple Unit) train with maximum speed over 400km/h. For high-speed operation tests of the new EMU, a high-speed railway infrastructure test-bed was constructed in a 28km long section of the Honam High-speed Railway. Diverse sensors and monitoring system was installed for continuous monitoring of the railway. Due to such effort, further demands and needs of the integrated monitoring system was derived in a more comprehensive and long-term perspective.

재난 및 안전관리 기본법 제3조에서 재난은 국민의 생명·신체·재산과 국가에 피해를 줄 수 있는 것으로 태풍, 홍수와 같은 자연재난, 화재, 붕괴 등과 같은 인적재난 및 전염병, 테러와 같은 사회적 재난으로 구분하고 있다. 기후변화에 따른 온난화로 지난 100년간 자연재해 발생횟수는 급격히 증가하고 있으며, 도시화로 인한 재산피해도 지난 반세기동안 10배 이상 급격히 증가하였다. 특히 사회기반시설이 재해로 인하여 피해를 입게 되면 그 피해액과 국민들의 고통은 한층 증가하게 된다. 하지만 재난관련 R&D 비중은 정부 전체 R&D예산의 1%에 불과한 실정이다. 올해 출범한 박근혜 정부의 140대 국정과제에서도 “총체적인 국가 재난관리체계 강화”가 포함되어 있다. 따라서 국가주요 기반시설의 건설 및 관리운영을 맡고 있는 철도공사를 포함하여 국토교통부 산하 공기업이 함께 재난관리 및 재난대응에 대한 연구를 수행하는 것이 필요하다.
