The Design manual for adjusting the capacity and LOS of facilities has been shared in urban railways and high-speed railway stations. However, the pattern of urban railways users and those of high-speed railway users are different from each other. For an example, the high-speed railway users tend to carry voluminous luggages and the transportation disadvantaged such as children and the elderlies. Accordingly, we see that the scale of facilities and the station itself should be constructed differently. The transfer facilities in the high-speed railway stations are classified widely into walking assisting facilities and convenient facilities. We invented the concept of PME (Pedestrian Moving Equivalent) and PWE (Pedestrian Waiting Equivalent)for the spatial calculation of those who are with wheeled luggages, back packs, and children to reflect the uniqueness of users in high-speed railway stations. These equivalents have been applied to the design of the facilities to asses the new Capacity and LOS that are users' favored.

The inland logistics center is a large scale of logistics facility that enables roads, rails, ports, and airports to carry out chained-transports and combined-transports, and the logistics center are established at the main logistics posts in order to reduce the cost of transport by mass transportation. However, it is expected that the capacity of Euiwang ICD, the only inland logistics centers in the capital area, will reach its limit before 2015, so it is required to establish another stations or to improve the existing facility. Especially, in case of Euiwang ICD, the expansion of the center is not possible because of its position, so it is required to establish new logistics centers in other places in order to raise the capacity of transport. Therefore, this study suggests to establish new metropolitan logistics centers on the western coast line in order to solve the problem of shortage of tract capacity that is brought on by the newly established inland logistics centers on the axis of the western coastline (Song-san Station and An-jung Station), and analyzes how the new logistics center will distribute railroad cargoes. By these, this study contributes to reduce the cost of transport by providing smooth railroad transport service.

Railway line segment deterioration can be affected by rail tracks, subgrades, bridges, tunnels, and line shapes. In this paper, an evaluation method is presented for the railway line segment deterioration using the analytic hierarchy process (AHP) and data envelopment analysis (DEA). The importance weights can be assessed systematically for component facilities from numerous experts using AHP. The importance weights provided by experts may differ according to each expert; however, the DEA enables the evaluation of railway line segment deterioration that reflects the variety of expert opinions using these importance weights.
