The railway crossing is very dangerous because the track intersects with the road there. Thus, The laws were designed for safety of the railway crossing and they are classified as to the acts for the road and the railroad. For safety of the railway crossing, there are 'Road/Railroad Crossing Improvement Promotion Act', 'Enforcement Decree of Road/Railroad Crossing Improvement Promotion Act', 'Rules on Construction of Railroad', 'Rules on Safety Standards of Railroad Installations', and 'Enforcement Ordinance of Cable way/Railway Track Act' in the acts for the railroad and there are 'Road Traffic Act', 'Enforcement Ordinance of The Road Traffic Act', 'Ruled on Structure and Facility Standards of The Road', 'Rules on Structure And Facility Standards Of The Rural Road' and 'Rules on Structure and Facility Standards of The Installations for Bicycle' in the acts for the road. Both the acts for the road and the railroad have standards for the structure of the railway crossing. However, they have different standards. Besides, they don't have standards for new facilities which were recently installed for safety of the railway crossing. Therefore, we suggest new standards for safety of the railway crossing.

Railroad construction requires a lot of budget, manpower, and equipment, and as a result, many accidents occur. Although efforts are being made at the national level to reduce the accidents at railway construction sites, the occupational accident rate is not showing a downward trend. Various efforts are needed to reduce accidents, the application of smart construction safety technology will be effective. However, if smart construction safety technology is introduced indiscriminately without analysis, duplicate investment may occur, which may lead to a waste of budget for railway construction. In this regard, this study analyzes accident cases at railroad construction sites through a survey of stakeholders and proposes smart construction safety technologies to be effective for those accident types.

Recently, many organizations such as, including government, railroad operational, railroad facilities managemental and research authorities have made a lot of efforts to identify and prevent hazards from leading to accidents and solve them all over the railroad industry. Railroad total safety technology development project conducted as one of national R&D projects has established business formation structure based on system engineering as an effort to define and give a solution to facing problems in the field of railroad. This paper is building procedures to verify the outcomes derived from this project. The verification process is the one for verifying the outcome produced in the final stage of the project or during the project. It makes sure that the system is satisfying the system requirements through verification of the outcomes produced after conducting the project for verification. We've made verification plan for technically reasonable verification using verification process developed through this research, and established master verification plan in the level of 15 detailed projects for interim and final outcomes produced.

Recently the geogrids are being used in some large projects such as Inchon International Airport construction, highway construction, and Korean High-Speed Railway construction with not only the merit of simple construction but also reinforcing efficiency for the soft ground. Main function of roadbed is to provide a stable foundation in terms of bearing capacity and settlement for the subballast and ballsat layers. Differential settlement of the railroad should be avoided. The cyclic laboratory model tests were performed to investigate the settlement behavior of geogrid reinforced railroadbed. The ratio of settlement of roadbed under cyclic loading with three layers of geogrid reinforced is less than 1/2 of the roadbed thickness without reinforcement.

본 논문에서는 철도차량의 능동조향시스템 연구를 위한 축소 조향대차의 장애물 검지시스템 구축에 대여 연구하였다. 철도차량에서 능동조향이란 곡선부 주행 시 차륜/레일 접촉에 의한 승차감 저하 및 차륜/레일의 마모와 소음을 줄이고, 고속주행을 위한 조향성능 및 주행안정성을 확보하기 위한 휠셋의 제어기술이다. 따라서 논문에서는 조향제어전략 및 제어기법을 연구하기 위한 축소 차량모델(견인대차와 조향대차로 구성)의 개발과정으로서 자동운전을 위한 장애물 검지시스템에 대한 연구를 수행하였으며 주행실험을 통해 그 성능을 검증하였다.

Although the railroad industry has progressed in terms of amount and quality because of the opening of the new express ways in 2004 and the construction and openings of the express railroads of cities, the establishment of safety has been poor so there has been lurking accidents and it resulted in big accidents like a Daegu subway fire. Therefore, this study is to minimize damages of life and property by establishing GIS, a map for emergency and Activity-Action and emergency reaction scenario through a web in case of emergencies mentioned before.

Currently, the Korean railway standards (KRS), managed by Korea National Railroad, have been managed by the Korean Ministry of Construction and Transportation. According to Korean railway safety law, which were established for the guarantee of railway safety, the management of KRS including enactment and revision of technical standards for railway vehicle and components, was committed to Korea Railroad Research Institute (KRRI). In this paper, the detailed master plan for the management of KRS will be introduced for the effective management of KRS, and KRS management direction for the future will be suggested.

As the Korea Railroad (KR) was privatized at the beginning of 2005, the Korean Railway Standards (KRS), which was managed previously by KR, have been managed by the Korean Ministry of Construction and Transportation. According to Railway Safety Law and ordinances, which are for the guarantee of safety in railway applications, the management of KRS including enactment and revision of technical standards for railway vehicle and components, was committed to Korea Railroad Research Institute. In this investigation, the detailed management plan and contents are introduced for the effective management of KRS.

Seismic Reflection Methods(TSP, HSP) have been applied in the junction between 2nd Adit and Main Tunnel (Solan Tunnel) of Youngdiong Railroad(Mt. Dongbaek∼Dokye). In this paper, methods and case study will be introduced to predict discontinuties in the tunnel before excavation by the Seismic Reflection Methods(TSP, HSP)and secure construction stability of the tunnel in blasting and excavation.

21century world is changing by leaps and bounds and this among one of new issue ready front environment be. Specially, the human social economy enemy, current of change is already happening even if there is in traffic industry that back activity. That is, point that railroad has competitive power and comparative advantage than other transportation until transportation system construction that is environment-friendly as part of country comparative power strengthening is embossed newly. On this time, railroad reached time that environment management that it is applied that is environment-Paradigm over management whole as well as field of technology such as construction and rolling stocks is necessary. This paper wishes to grope plan that introduce this in railroading hereafter by examining necessity introduction in railway operation through environment marketing example. It must go to Ready front Green-railway.
