  • 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.

  • In this paper, 18 railway stations in Gyunggi-do are selected as metropolitan transfer centers out of 203 stations based on three elements. They are the number of passengers, the level of connection transport, and the level of relevant plans. For 18 stations the level of service (LOS) is analyzed for connection transport system. As a result, half of them are found to be below LOS "D". In order to maximize the use of those railway stations, a method is proposed to upgrade the level of service to "C" above. Finally, the improvement plans are suggested for two acts. In the Special Act on Metropolitan Traffic Management of the Metropolitan Region, the central government financial support ratio is suggested from 30% to 50%, from "necessary costs" to "total costs." In the Act on National Integrated Transport System Efficiency, 50% for connection road and 70% for connection raiway are suggested.

  • The modern logistics has tried not only to convert the conventional packing system into unit load system using pallet but also to enhance the fitness between packing facilities and transport modes. This is based on the goal to reduce total logistics cost by improving logistics efficiency. Since the packing unit can affect both loading rate and loading facilities, basic form of packing unit is very important to unit load system. The object of this study is to develop a new method for evaluating the effectiveness of standardized packing module. The new method is based on measure of effectiveness (MOE) which are identified by expert survey. This study has originality in that the collecting method for effectiveness of standardized packing module has not been developed up to now.

  • This study aims to conserve and monitor energy use in public sewage treatment plants by utilizing data from the SCADA system and by controlling the aeration rate required for maintaining effluent water quality. Power consumption in the sewage treatment process was predicted using the equipment's uptime, efficiency, and inherent power consumption. The predicted energy consumption was calibrated by measured data. Additionally, energy efficiency indicators were proposed based on statistical data for energy use, capacity, and effluent quality. In one case study, a sewage treatment plant operated via the SBR process used ~30% of energy consumed in maintaining the bioreactors and treated water tanks (included decanting pump and cleaning systems). Energy consumption analysis with the K-ECO Tool-kit was conducted for unit processing. The results showed that about 58.7% of total energy consumed was used in the preliminary and biological treatment rotating equipment such as the blower and pump. In addition, the energy consumption rate was higher to the order of 19.2% in the phosphorus removal process, 16.0% during sludge treatment, and 6.1% during disinfection and discharge. In terms of equipment energy usage, feeding and decanting pumps accounted for 40% of total energy consumed following 27% for blowers. By controlling the aeration rate based on the proposed feedback control system, the DO concentration was reduced by 56% compared pre-controls and the aeration amount decreased by 28%. The overall power consumption of the plant was reduced by 6% via aeration control.

  • The Safety Transmission Unit(STU) is a critical device used in railway systems to ensure safe and efficient operations by providing communication between trains and railway infrastructure. It is responsible for transmitting vital information and commands, allowing for the control and coordination of train movements. The STU plays a crucial role in maintaining the safety of passengers, crew, and the overall railway network. This paper presents the design and testing of a STU for the next-generation wireless-based train control system. An analysis of european and domestic standards was conducted to review requirements and ensure the design of a STU for the train control system meets international standards. Based on this analysis, hardware and software designs were developed to create an internationally recognized level of safety for the communication device. To verify the functionality of the STU, a simulator was developed, and it was confirmed that the designed features were successfully implemented.

  • The estimation of total travel time on highway link for a day or year is the most important process for the feasibility analysis of highway or railway. Most of current guidelines for feasibility studies have been based on the time-traffic volume relationship from the BPR, and the traffic volumes have been determined by the application of the design hour factor to the annual average daily traffic volume. Both of the BPR function and the application of the design hour volume may result in the over-estimation of travel time due to the fact that the traffic volume on the large portion of highway links in Korea are close to the capacities. This study proposed a new way which is based on the distribution of hourly volumes for a year. It could be closer to the real situation, and provide more reasonable estimation. This methodology was validated for the national highways, but may be applicable for any type of highway with the AADT.

  • Due to the revitalization of urban development, the number of cases of excavating tunnels adjacent to existing subways is increasing. This may affect the structure and track of the existing subway, resulting in reduced stability and usability. In this study, we verified the adequacy of the proximity evaluation range to ensure the stability of new tunnels and existing subways when excavating adjacent to tunnels, and proposed a quantitative correction rate considering various conditions. Conditions for applying the correction rate considered rock grade, geologically weak section, structurally weak section, and structural deterioration section. It is hoped that a more accurate proximity evaluation will be performed by applying a quantitative correction rate that considers rock and geological conditions, structure status, etc. to the proximity evaluation standard.

  • The Transport policies in Korea have been planned and implemented as a part of a larger economy policy based on the achievement of economic growth. As a result, previous transport policies have been focused mostly on the supply of transport infrastructure. The average annual economic growth of six percent and a twelve percent growth in motor vehicles until the late 90s led to the acceleration of the imbalance between the supply and demand of infrastructure. As such, there is a need to establish an innovative transportation policy in order to increase national competitiveness and provide momentum for national growth in the Twenty one century. This research has developed strategies and policies based on interviews that were carried out with specialists in transport field. Moreover, some transport policies have been established for the year 2020 through the conducting of a survey. The survey was conducted by interviewing respondents on making the priority of transport policies. which was then analyzed using the Data Envelopment Analysis with ranked voting data. The results are as follows. The most urgent matter was considered to be the development of a inter-modal transport system, followed by an integrated service system for public transport, and the need to increase the competitiveness of the transport and logistics industries and to further transport safety. Meanwhile, the provision of transportation for disabled people as well as the elderly was considered to be less important in Korea than in welfare nations. This stems from the belief as further attention needs to be paid to the construction of a public transport system, the establishment of transportation networks construction in preparation for reunification and the North-East Asian era, as well as the privatization of the transport infrastructure.
