Much research has been actively done so far on the inconvenience of each urban railway station; however, Research is on importance factor analysis on transfer facilities by considering characteristics of railway stations is relatively insufficient. In this study, a novel method of finding causality between transfer facilities(movement, information, comfortability, etc,) in terms of demands and platform types is provided by using SEM(Structural Equation Model). The results of SEM analysis show that a large demand transfer station if combined with island and segregate platform types, has a higher importance factor with respect to information facility, movement facility position and comfortability. In addition, a medium demand transfer station if combined with separate and separate platform types has a higher importance factor with respect to information facility, movement facility and comfortability.

The total number of railroad stations managed in Korea is 322 (including general and wide-area railways), and a considerable number of stations are aging. In terms of the size of the existing railway station and the number of entrances, it has not been possible to secure adequate service capacity, and the demand for station improvement is increasing due to changes in surrounding conditions such as urban development. In the past, railroad stations were focused on the simple function of a connection passage in terms of maintenance or management, but in recent years, railroad stations are also changing to an atmosphere that they should be reborn as a user-centered comfortable, convenient, and safe service provision space. In this study, a case study related to the improvement of the old railway station was conducted to derive an improvement plan that meets the improvement standard of the old station, and the service level evaluation standard was developed. By introducing the concept of service level (LOS) in the development model, station congestion, station movement convenience, and station safety were selected as evaluation indicators. In addition, this development model applied an analytical stratification technique to divide various evaluation elements of each indicator into major and detailed elements and derive the relative importance of the elements by class. Priority for improvement was derived using the ratio of the number of E and F on the LOS for each facility. Based on this study, it is expected to be helpful in using it as an evaluation criterion for improving objective and equitable railway station.

This study classifies the types of urban railway stations that reflect the location characteristics of urban railway stations, the structure and form of station taxes, and the number of users, and the level of inconvenience in the transfer movement line for users by station type, the number and connectivity of transfer information, and the level of transfer convenience facilities. The number of installations, conflicts between users, and transfer information signs were analyzed. As a result of data analysis, it was found that the factors that cause the most inconvenience to urban rail users when transferring are the length and curvature of the transfer line, pedestrian density and number of passengers in the transfer passage, presence or absence of transportation convenience facilities, and the size and height of transfer information letters. These transfer inconveniences were objectified, quantified, and presented as evaluation indicators that can measure the transfer convenience of urban railway stations. Additionally, an evaluation scale was developed to measure the service level for each evaluation indicator. The evaluation scale for each indicator presented six levels by applying linear interpolation based on the maximum and minimum values of data derived through field surveys. However, it is judged that a comprehensive evaluation of transfer convenience that combines the importance and weight of each convenience evaluation indicator should be established through future research.

The congestion of pedestrians impedes the utilization efficiency of a subway station. Conflicts among pedestrians due to unseparated pedestrian flows not only increase the impedance of pedestrian mobility but also negatively affect on pedestrian safety. This paper analyzes the travel characteristics of bi-directional pedestrian flow based on microscopic movements, and evaluates the operation efficiency on separating the traffic line. The subway station was simulated in a 2-D grid structure by applying Discrete Element Method, and the movement is organized in each cell of the grid. As a result, the model explicates that separating the traffic line and encouraging the 'Keep right rule' would be mostly effective for the conflicting flows. Therefore, applying the 'Walking Guidance System' would be efficient to improve the pedestrian convenience and mobility.

In the development of railroad station area, there are many factors about business management, but the interest of railroad users is an important factor as customer satisfaction. It is necessary to have the quality estimation of railroad service, and important factors of service as customer satisfaction aspects can be supply, reliability, convenience, and safety. In this study, primary factors are deduced in the efficiency aspects of railroad station facilities from analyzing relative importance index using AHP(Analytic Hierarchy Process) methods. The most high rank important factor is railroad station user facilities, and the AHP importance index of passenger facilities and elevator facilities for KORAIL personnel and facility users is index. The third of KORAIL personnel is movement facilities, but facility users index is sanitation. And the low important factors of KORAIL personnel and facility users are shown as the platform in passenger facilities, the rest facilities in waiting room, the escalator in going up and coming down facilities, the escalator in movement facilities, the raised letters block in guide facilities, and the parking lot in subsidiary facilities.

This article analyzes the obtained data on consciousness survey of disabled and non-disabled pedestrians, and proposes fundamental data for public strategy in order to enhance facilities in subway stations in advance. This paper conduct literature review, new listing survey related to 'The Code for Improvement of Convenience for Moving Vulnerable Pedestrians', and Modified-Importance-Performance Analysis (M-IPA). The results show that disabled pedestrians want enhancement in information facilities as a whole. In addition, the results show that several improvements needs to be applied to accessible sidewalk, to informative notification, to alarm and evacuation system and to toilet for disabled pedestrians. This indicates that disabled pedestrians heavily concentrate on accessibility to subway station and provided information compared with disabled pedestrians.

하천의 기능은 공학적 관점에서의 이수, 치수, 환경 기능 외에도 사회적 관점에서 역사 문화 기능을 포함할 수 있다(우효섭, 2009). 1990년대 말부터 하천복원사업이 본격화 되면서 최근에는 하천환경 기능 외에도 친수를 포함한 역사 문화 기능이 하천관리의 주요 축으로 고려되거나 포함되고 있다. 이 과정에서 하천의 역사 문화 기능을 주문하는 요구가 증가한 이유로는 하천복원사업의 지역적 획일화, 친수(심미) 요구 증대, 지역 경제성 제고, 환경(생태, 문화 등) 가치 증대 등 사회경제적 정책적 환경 변화가 기인한 부분이 크다고 할 수 있다. 이러한 측면에서 볼 때 하천의 지속가능하고 효과적인 관리와 보전을 위한 방안으로 하천의 역사 문화적 요소를 사회 경제적, 생태 환경적 요소와 연계하는 접근방식은 유용할 수 있다. 이를 위해서는 우선적으로 지역공동체가 형성해온 물 문화의 특수성을 감안하여 하천유역의 역사 문화적 소재 및 자원을 발굴할 필요가 있다. 그리고 조사 수집된 다양한 역사 문화적 소재 및 자원은 하천사업 및 관리의 주요 콘텐츠로 활용되기 위한 창출과정을 진행함으로써 사회 경제적, 생태 환경적 요소와 연계할 수 있다. 본 연구에서는 하천유역을 대상으로 문헌조사 기반의 사전조사와 심도 있는 현장조사(탐문조사 등) 수행결과를 토대로 향후 하천복원사업에 활용될 수 있는 다양한 역사 문화적 소재와 자원 등에 관한 콘텐츠를 도출하였다. 또한 콘텐츠 활용방안은 하천 역사 문화 자원의 세부적인 콘텐츠를 아우를 수 있는 테마설정을 통하여 대상지 및 지역특성(치수 안전, 지역요구, 물 문화 가치 등) 등을 고려한 방안을 제시하였다. 특히, 친수 측면에서 현재 수변공간을 이용하는 방문자수, 목적(산책, 스포츠, 낚시, 물놀이, 레저 등) 등에 대한 패턴과 지역 인구 현황, 접근 인프라(교통, 이동로, 편의시설 등), 주민 요구도 등 잠재적 친수도는 물 문화 형성이라는 측면에서 볼 때 주요한 고려사항이라 할 수 있다.

Increasing transportation dependence on the metro system has lead to the convenience of passengers becoming as important as the transportation capacity. In this study, a pedestrian simulator has been developed that can quantitatively assess the pedestrian environment in terms of attributes such as speed and distance. The simulator consists of modules designed for 3D indoor map authoring and algorithmic pedestrian modeling. Module functions for 3D indoor map authoring include 3D spatial modeling, network generation, and evaluation of obtained results. The pedestrian modeling algorithm executes functions such as conducting a path search, allocation of users, and evaluation of level of service (LOS). The primary objective behind developing the said functions is to apply and analyze various scenarios repeatedly, such as before and after the improvement of the pedestrian environment, and to integrate the spatial information database with the dynamic information database. Furthermore, to demonstrate the practical applicability of the proposed simulator in the future, a test-bed was constructed for a currently operational metro station and the quantitative index of the proposed improvement effect was calculated by analyzing the walking speed of pedestrians before and after the improvement of the passage. The possibility of database extension for further analysis has also been discussed in this study.

The layout of facilities, in relation to information and navigational displays, has great influence on subway satisfaction, and tend to vary depending on the types of subway platform and transit station. However, until now, few studies have covered such aspects as of yet. Starting from this viewpoint, the purpose of this study was to use an IPA analysis technique to analyze that satisfaction on the importance of facilities to aid in accessibility, such as elevators and escalators, transit amenities and information and navigational displays depending on the types of platform and transit station. To do so, we've classified 15 metropolitan stations according to types of platform and transit station and analyzed differences in user importance and satisfaction as well as improvements for platforms and transit stations of similar type. By the analysis results of this study, we've concluded that the proper selection and positioning of elevator and escalator facilities and information and navigational displays was important when designing the subway station according to platform type (separate platform) and or according to the transit station type (cross, L, T types) where pedestrian flow heavily intersected. We considered that such analysis results would be helpful in the design of new stations and the enhancement of existing stations pursuant to a new direction that minimizes user inconvenience, and that improvement items should be developed first according to the platform and transit station types, which would be helpful in enhancing the efficiency of the subway improvement cost.

The conflict of opposing pedestrian traffic-flow in a subway station(made up of stair, passageway, and escalator) diminishes the convenience and mobility of its users. In addition, the station's efficiency would be negatively affected by the growth of delay and queue length in pedestrian facilities. As these phenomena have been resulted by the overlapping in pedestrian's traffic-line, the separation of it would alleviate these problems. For the criteria and methodology of separation, this paper has investigated the bi-directional queue length and delay on the entrance of each facility (stair, passageway and escalator). Since the pedestrian flow exists bidirectionally, we have used the weighted average by inflow rate for the delay value. For the optimization of the separation, the Genetic Algorithm has been utilized in order to minimize the delay.
