Failures of equipments are linked directly to extensive damages of human lives or financial losses from the increasing uses of railway signaling equipments utilizing computers. Then safety organizations have to establish for guaranteeing safety during the system life-cycle. In this paper, we examine the relationship between railway signaling standards and other safety standards for safety meaning establishment.

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.

Safety of railway systems is made by understanding causes and process of railway accidents and grasping contents of a many of accidents. Now, Being carried out a research and analysis about an extensive areas(the whole country, the metropolitan area, the five metropolitan cities, the city of three hundred thousands and over of people) and field, thereafter the National Transportation (Railway) Database has been constructed and developed to prepare the base that reduced an overlapping survey using a standardized-material offer. A purpose of this research is to derive plans to apply National transport DB including information in the field of transportation systems to domestic railway safety management. The research analyses the present conditions of establishing national transport DB, and reviews problems when that use to railway system. As being based in this, the research derived definitions and using plans of layers available to use, and plans of establishing and systematizing information for desirable railway network.

There are several international standards, established by IEC, for RAMS management of railway system. Those int'l standards are described only total RAMS management, but RAM and safety activities have dissimilar characteristics. In this paper, we suggest the separated RAMS architecture with RAM and safety activity for railway signaling system.

Railway safety management information systems are now being developed by various railway related organizations. A large number of railway safety related data were gathered from railway operators, railway infrastructure manager and railway intendance, etc. The meaning of these data can easily be defined by each organization or developer with little regard for reusing of data by others. Until the present, the main efforts for data management focused on classifying the railway safety data by subject for the developer's convenience and how to combine these data each other is not interested in. In this study, data integration is considered from the viewpoint of combining them semantically in order to get more useful information from partially informed data of multi agencies.

The objective of this study is to develop accident scenario models for the risk assessment of railway casualty accidents. To develop these scenario models, hazardous events and hazardous factors were identified by gathering various accident reports and information. Then, the accident scenario models were built up. Each accident scenario model consists of an occurrence scenario model and a progress scenario model. The occurrence scenario refers to the occurrence process of the event before the hazardous event. The progress scenario means the progress process of the event after the hazardous event. To manage a large amount of accident/incident data and scenarios, a railway accident analysis information system was developed using railway accident scenario models. To test the feasibility of the developed scenario models, more than 800 domestic railway casualty accidents that occurred in 2004 and 2005 were investigated and quantitative and qualitative analyses were performed using the developed information system.

The intelligent safety system for level crossing which employs information and communication technology has been developed in USA and Japan, etc. But, in Korea, the relevant research has not been performed. In this paper, we analyze the cause of railway level crossing accidents and the inherent problem of the existing safety equipments. Based on analyzed results, we design the intelligent safety system which prevent collision between a train and a vehicle. This system displays train approaching information in real-time at roadside warning devices, informs approaching train of the detected obstacle in crossing areas, and is interconnected with traffic signal to empty the crossing area before train comes. Especially, we present the video based obstacle detection algorithm and verify its performance with prototype H/W since the abrupt obstacles in crossing areas are the main cause of level crossing accidents. We identify that the presented scheme detects both pedestrian and vehicle with good performance. Currently, we demonstrate developed railway crossing intelligence system at one crossing of Young-dong-seon line of Korail with Sea Train cockpit.
