Seoul`s subway is an important urban mass transportation system as it carries more than 4 million people for a day. It occupies 30% of transport modal share of Seoul citizens. To support this important mission, the outside entrance system of the subway was designed to maximize accessibility from the outside to the station buildings. However, the number and the layout of entrances were planned based on a uniform plan that the national government prepared for the entrance system of urban railways. Therefore, the entrances of the subway system of Seoul were planned without considering the unique characteristics of each station area. Applying the uniform national plan to all the subway stations raises problems as follow. First, some entrances can be inefficient in connecting the places where there are heavy volumes of potential subway users to the stations. Second, it is also possible that more than one entrances may be unnecessarily placed where accessibility is already sufficient. As a result, the entrances could encroach on limited space of sidewalk. Therefore, this study examines the current subway entrance system to identify its problems and attempts to propose a scheme for reorganizing entrances befitted with attributes of each station area and eventually improve pedestrian environment. . This study focuses on the No.2 subway line that passes the major centers of the city, and since a long time has passed after the completion of the subway system, buildings in the station areas adjacent to the subway entracnes are getting redevelopment pressure. Thus, when these areas are redeveloped, the proposals made in this study could be most useful. By conducting a field study and data analysis, this study identifies the following as the problems of the current entrance system of the subway in Seoul. First, the entrances encroach on pedestrian space that is already limited, and the stations on elevated highway create unpleasant pedestrian space; Second, some entrances could be inefficiently used and create monotonous cityscape; Third, a structure that connects the stations on elevated highway and the sidewalk has negative influence on walking environment such as creating dark space; Fourth, it is often the case that public establishments and residential districts located close to a station are not fully accessible from the subway through entrances. To provide solutions to the problems above, this study investigates all the entrances of the No.2 line and grouped them into certain types, intending to propose the reorganization scheme for each pattern. This study established three standards for the classification, which are the form of the station and the location of the entrances, and the width of adjacent roadways. These are important characteristics of the entrance itself and the areas surrounding the entrance that affect the reorganization schemes. Then, the authors, based on the analysis of the uses of buildings surrounding each entrance, proposed entrance reorganization plans for each type. This study finds that the entrances of underground stations located on 4 way intersections, that are formed by roadways more than 6 lanes, are adjacent to sizable commercial facilities and large office buildings. Also, high density residential districts are present near the entrance of this kind. For this type, we suggest installing the subway entrances inside the contiguous building. This proposal is most possible for this type since the buildings in such areas have relatively large floor space. As the road width becomes narrower, overall density decreased. For the type of the entrances that are located on the intersection formed by narrower roadways, we propose that two entrances could be combined into one so that removed entrance could free up large space for pedestrians. For the entrances located on mid-blocks, the study suggests that the entrances could be installed inside the adjacent building when large commercial or office buildings are nearby. When overall area is developed with low density, the city government is recommended to purchase a lot near the current entrance to install one vertical to the sidewalk so that sidewalk could be preserved for pedestrians. For the elevated stations, the authors propose installing a bridge connecting the stations and adjacent buildings, but this would be only possible when there are commercial or office facilities nearby with enough floor space. The study summarizes the pros and cons of each solution. Lastly, the study applied the proposed improvements on the Kyodae subway station entrances as a case study. It demonstrates how the proposed entrance reorganization schemes can be applied. In conclusion, we suggest the direction of the future study that can contribute to policymaking. First, to translate the proposal installing the entrance inside buildings into a reality, an incentive should be given to building or land owners. The future study should investigate which kinds of incentives exist and be effective in various situations. There are needs for research to examine potential problems that might arise during a negotiation process between the public and private sectors, assignment of cost for installing entrances, how and who to maintain entrances. Also, research studies should examine proper number of subway entrances for each station. It is important to draw up an accurate, but flexible standard for determining the number of entrances for the subway stations. This study is limited in that it only examines the entrances of the No.2 line subway stations. In the future, a research study investigating the whole line of the Seoul subway will be able to draw more persuasive policy recommendations.

This study aims to explore problems of the way-finding system of Seoul subway station. In case of Seoul, there has been many problems of losing a way, looking around, going on a bootless errand, going back, asking and so forth for subway users whether they are foreigners or not. Specifically focused on four densely-used subway stations which are Seoul Station, City Hall Station, Express Bus Terminal Station, Myeong-dong Station, the research arguments are developed through site visit, investigation and analysis, discussion meeting and interviews. Investigating the real condition of signs in four subway stations, 3 types of problems are determined. The most serious problem is that the signs is not working as a way-finding system at the level of transfer guide, way-out and upper space guide, and circulation decision point guide. These problems are mostly driven because of failing to properly locate the sign and to provide the necessary level of information detail. The reason of those problems I examined from the point of planning process, production structure, and finally organization. In overall, the production of subway signs pre-empt sign system planning as well as subway sign manual do subway design guideline. Also the subway sign guideline and manual have not been developed based on behavioral and cognitive study, so it does not have any exact measuring standard and human scale to locate the signs. Policy implication is to suggest a supplementation of subway sign guideline and manual based on user’s behavioral and cognitive characteristics, integrating interagency for better quality control of way-finding system, and several demonstration projects to improve sign system and remodeling projects.
