Universal Design involves designing products and spaces so that they can be used by the widest range of people possible. Universal Design evolved from Accessible Design, a design process that addresses the needs of people with disabilities. This paper introduces the universal design concept through analysis of causes of railway accident within the urban railway station. Railway accident analysis was performed by the internal facilities. We analyzed the standard of accident type, accident cause and accident subject such as elevator, escalator, stairs etc.

The prestressed concrete girder bridges have been used widely at the domestic national road as well as highway because it is great in the functional and economical efficiency. Also it has the advantage of convenience of design and construction due to being given standard sections. However it could be easily verified that a standard section of P.S.C girder is excessive design, which has much more redundancy than is necessary against design loads. Thus, in this paper the formulation of the optimum design for PSC girder railway bridge is suggested and dominant design variables and constraints are inquired as performing the optimum design. The objective is adopted as total cost of PSC girder bridge ,and in order to effective optimum design, design variables are formulated as PSC girder section dimension and girder space as well. And constraints are formulated according to Korean railway design specification and considering construction-ability such as PS anchorage and girder space. Using the proposed optimum design system, optimum PSC girder bridge design has been performed. And from the results of analysis it is suggested to denote the optimum section which satisfies the structural safety ,and economical efficiency all together.

As a part of several Eurasian initiatives, the Korean government is trying to reconnect railways through North Korea to the Asian continent. If South Korea could build a network using railway, it would be a chance to develop a robust economic environment and to motivate economic growth. In the railway reconnection project between North and South Korea, the most important part of the railway roadbed sector is repair or improvement, and then construction of a new line through North Korea. There are not many big differences in the geological conditions; however, climate condition varies greatly during winter. The most significant condition in the safety of railway operation is frost-heaving. However, since South Korea has a relatively mild climate condition compared with North Korea, design and construction specifications under severe weather conditions in winter have not been prepared. This study proposes a plan for revising the railway design standard for underpass structures through an analysis of international standards, leading to site construction to prevent frost-heave.

Railway is compsed in various components, such as subgrade, track bed, sleeper, rail, and overhead line, on a linear space. Therefore, comprehensive work for various design standards and guidelines is required when designing a railway facility. For this reason, much time and effort are required to review the relevant design standards and guidelines. While, automatic legal check system for BIM models has been developed in the architectural engineering, it has not been developed in the railway engineering. This study reviews the korean design standard and the korean code for railway engineering, and suggests some rule items of logical information. Comparing the suggested rule items to the railway BIM library, items of logical information and additional attribute information are obtained. The analysis results of railway design standards and BIM library presented in this study would be utilized for defining rule-set items that is essential for development of the automatic legal check system for railway BIM models.

The real-time railway safety monitoring and control system is for prevention of safety accidents, and this system adopts DDS (Data Distribution Service) standard based data transmission method to support integrated management of data from existing on-site safety detection devices. In this paper, we introduce the design of DDS-based data specification from on-site signal equipment on the conventional railway. For this, we (1) design UML data model of KRS SG 0062 standard which defines existing data specification, (2) define DDS Topics for DDS transmission and map KRS model to DDS Topic model, (3) suggest data transformation rules and (4) design network control QoS polices. In addition, we analysis actual on-site log data and validate our data specification design. DDS-based data transmission enables data compatibility among on-site devices and the real-time railway safety monitoring and control system, and allows efficient network management for a large amount of data transfer.

Purpose : As the number of the transportation poor has increased, the application of Universal Design on urban railway station has recently been focused. However, the current criteria used in domestic areas did not show the characteristic of facilities within urban railway station. Therefore, this study aims to explore the detailed criteria in applying ideas from Universal Design to sanitary facilities, especially toilets within railway station. Method : This study explores the criteria by evaluating findings from previous studies. First, the current situation of sanitary facilities in railway station is assessed. Then, the detailed criteria applicable to railway station toilets are concluded, by reviewing types of transportation poor and principles of Universal Design. Result : Findings from this study are as follows. First, the current criteria applied to railway station toilets lack ideas of Universal Design, so the better criteria applicable to sanitary facilities in railway station are necessary. Second, standard criteria used in domestic areas with newly additional criteria suggest that sanitary facilities should be established according to those criteria. Taken together, the better sanitary facilities should be provided to railway users through the application of Universal Design to railway station toilets. Implication : For the future users in railway station toilets, the additional research on types of diverse space and other sanitary facilities within railway station should have been continued.

Purpose: Recently, Universal design has been applied to a variety of concepts of social integration in the national legislation and institutions, however, the applying to urban railway station is not satisfied. Most of cases, the handicapped can not work continuously, universal design must be provided. Methods: This study derives the detailed criteria through comparing and analyzing an national and international universal design-related system in transit zone. And the status is investigated in transit zone of domestic urban railway station. Improved national standard requirements are derived considering the type of the handicapped and universal design principles. Result: The domestic status shows that the most lacking entry criteria is not specified in national standards or the design is a lowest-level required by criteria through comparing detailed criteria drawn into domestic analysis. Therefore, in order to provide a pedestrian environment to meet the universal design principles and requirements for the handicapped, there is a need to re-establish with a specific national standards. Implications: This study will draw on universal design standards for seamless transfer in transit zone of urban railway station. The next studies are needed to target the overall paths ranging from outside to landing in urban railway station.
