근대공간의 장소성과 기억에 관한 연구 <서울역>, <온양민속 박물관>, <옥포조선소>를 중심으로

한국의 근대화 시기는 1920년대 식민지 시기와 1960년대 경제개발시기 두 시기 나누어진다. 근대화시기에 만들어진 공간들은 대다수 국가주도형으로 생산된 공공의 공간들이다. 이러한 근대공간들은 기능성이 강조되는 공공 생산의 장소이자 근대 국가시스템의 장소정체성을 상징하는 국가권력 공간들 이었다. 사회의 변화에 따라 근대공간들은 이제 더 이상 장소적 기능을 상실한 채 모뉴멘트 건축물로 존재하며 과거의 장소정체성에 새로운 가치를 부여할 개념규정이 필요한 시기이다. 간이역, 발전소, 탄광, 물류창고, 폐 공장 등... 근대공간에 새로운 장소정체성이 확립되는 과정과 장소와 기억의 문제를 영상기록 하여 근대화의 큰 특징인 사고의 변화과정과 공간에 투영된 근대적 개념들, 근대사회의 제도, 체계 수립 과정에서 장소성, 공간 속 사람들의 관계성에 주목하고자 한다. 근대공간과 기억의 관계는 < 서울역 >에서, 근대공간과 근대 기록의 관계는 <온양민속박물관>에서, 근대공간과 장소정체성은 <옥포 조선소>에서 찾아본다. 각 장소의 정체성과 기억의 관계는 구술목소리와 영상기록을 통하여 근대공간(장소성)과 개인구술(기억)의 모순된 힘의 관계를 알아본다. The history of modernization of Korea is divided into two folds of the colonial era in the 20's and the economic development era in the 60's. Most of the spaces built in the process of modernization were public spaces developed by the drive of the government. These spaces of modernization are functionality-oriented public places of production and at the same time, and they are the spaces of national power to symbolize the identity of national authorities. Along with changes in the society, modern spaces were reduced down to monument buildings without functionality and this requires new definition to renew the identity of modern spaces. Small stations, power plants, mines, warehouses, abandoned factories, and etc... the study has paid attention to the process of changing thought, one of the main characteristics of modernization, the relations of modern concepts projected in the spaces, framework of modern society, and placeness in the process of framework building and relations of people in the spaces with video records on the process of rebuilding new identity of modern spaces and memories of the spaces. The relations of modern spaces and memory were explored in < Seoul Station > while the relations between modern spaces and records and place identity were explored in < Onyang Folk Museum > and < Okpo Shipyard > respectively. In the relations between space identity and memory in each space, the ironic relations of power in modern spaces (placeness) and personal narrative (memories) were explored with oral narrative and video footage.

여름철 지하역사 실내환경 특성 및 쾌적성 평가에 관한 연구

The purpose of this study is to evaluate passenger's comfort in subway stations in the summer. Six subway stations in Seoul were selected and a survey was carried out targeting subway passengers. The survey was carried out from <TEX>$12^{th}$</TEX> to <TEX>$28^{th}$</TEX> in August, 2014. The questionnaire of comfort consisted of five environmental factors; thermal, air, light, acoustic and overall comfort and each items consisted of a five-point scale on each comfort. Tablet PCs were used to make passengers check the questionnaires quickly. At the same time, temperature, humidity, air velocity, carbon dioxide(<TEX>$CO_2$</TEX>), illumination, noise, and the concentration of particular matter(PM) in subway stations were measured. The respondents were 1739 people of various ages. As a result of the survey on the evaluation of each comfort, most respondents answered they felt 'neutral' or 'comfortable' for thermal, air and light environment. The respondents who answered 'discomfortable' were more than other responses relatively for acoustic environment. And there were gender differences significantly for the evaluation of air and acoustic environment. The evaluation from male was better than on female. As a result of the relative weights of the four factors contributing to the overall comfort, all factors contributed significantly and air environment was the highest contribution to the overall comfort and there were also gender differences of relative weights of the factors.

Characteristics of Thermal Environment in Subway Stations of Seoul during Summer Time

The purpose of this study is to investigate the thermal environment of subway stations in Seoul and to suggest ways to improve the thermal environment and cooling energy during summer time. Major thermal environmental indexes were measured in six subway stations of three transit stations during summer time. The temperatures and relative humidities over the design conditions were observed in many concourses and platforms of the subway stations and the thermal environments of platforms were comparatively worse than concourses in most stations. Predicted Mean Vote(PMV) values were ranged over 1, which indicates “slightly warm”, in almost all stations. The air temperatures of subway stations during non-operating hour were up to 6.6°C higher than outdoor air, which presumably caused by the thermal storage during day time. The high enthalpy of subway station during non-operating hour is assumed to provide bad thermal environments to passengers in the early morning and also to cause more cooling energy during morning rush hour. Pre-cooling using low-enthalpy outdoor air before the early morning operation should be considered to improve thermal comfort and to save cooling energy even during summer time.

Space syntax 기법을 활용한 Social Path 효과분석

보행자는 일반적인 보행로뿐만 아니라 건물을 통과하거나 넓은 공간을 가로지르는 등의 비정형적인 보행 경로를 통해 다양한 방식으로 이동한다. 본 연구는 이러한 보행 경로를 social path로 정의하여 보행 네트워크의 범주 안에 포함시켜 정의하였다. 기존의 보행 접근성 연구에서는 이러한 보행 경로를 고려하지 못해 대상지의 공간적 위계 수준과 각 가로의 연결성을 올바르게 평가하지 못하였다. 이를 개선하기 위해 본 연구는 대중교통의 요지임과 동시에 상업 시설이 밀집된 서울의 주요 대상지를 선정하여 social path의 효과 분석을 수행하였다. 이를 위해서는 네트워크 공간 분석에서 활용되는 space syntax 기법의 공간 통합도(Integration)를 평가 지표로 설정하였다. 분석 결과, social path로 인해 각 가로의 연결성이 변화됨과 동시에 보행자의 최적 경로가 합리적으로 바뀌는 것으로 나타났다. 특히, 대상지 내부의 주요 가로와 social path의 개선효과가 두드러졌다. 이러한 점을 통해 social path의 연결성이 뛰어나고 보행자의 최적 경로를 보다 현실적으로 구현할 수 있다는 점을 증명하였다. Pedestrians not only walk along pedestrian pathways, but also choose unusual routes such as passing through buildings or crossing large scale open spaces. This study defines these unusual paths as social path, and includes them into one of the pedestrian road categories. Previous pedestrian accessibility and route choice studies could not evaluate correctly the space connectivity or optimal route because the social path was not considered properly. Therefore, this study analyzes the effectiveness of the social path in view of space connectivity focused on Coex and Seoul stations in Seoul, which are representative transit oriented development(TOD) areas. Global integration, which is widely used in network analysis, is selected (as performance index) to identify the space hierarchy and define new pedestrian links. The study results show that the network connectivity is improved especially in the main streets and social paths. This study demonstrated that the social path should be considered in finding the pedestrian optimal route from the practical perspective.

3차원 지적정보 기반 맞춤형 주거 공간정보 서비스 모델 개발

Recently, Through the linkage and opening, the fusion of the spatial information, it is necessary for productive ecosystem to provide a variety of information and to increase the civil use. Depending on the economic growth, demand for quality of life and well-being has been on the increase. Spatial information service contents for the public convenience has emerged to solve the problem such as health, safety, welfare and discomfort of daily life This study aims to implement search services for a tailored residence space through the three-dimensional data modeling on cadastral information. To achieve this goal, we established the requirements for deriving a registered object by investigating recent trend with respect to existing cadastral data model and defined property and relationship. Focusing on Songpa-gu, Jamsil station in Seoul, we implemented search services for a tailored residence space for three-dimensional right analysis in conjunction with residential and commercial complex building. As a result, we derived a way to supply 3D cadastre information through open platforms (VWorld) and to represent efficiently, which is able to improve the quality of spatial information service contents for the public convenience as well as to widen utilization of information.

Grid Method 기법을 이용한 베이지안 비정상성 확률강수량 산정

A Bayesian nonstationary probability rainfall estimation model using the Grid method is developed. A hierarchical Bayesian framework is consisted with prior and hyper-prior distributions associated with parameters of the Gumbel distribution which is selected for rainfall extreme data. In this study, the Grid method is adopted instead of the Matropolis Hastings algorithm for random number generation since it has advantage that it can provide a thorough sampling of parameter space. This method is good for situations where the best-fit parameter values are not easily inferred a priori, and where there is a high probability of false minima. The developed model was applied to estimated target year probability rainfall using hourly rainfall data of Seoul station from 1973 to 2012. Results demonstrated that the target year estimate using nonstationary assumption is about 5~8% larger than the estimate using stationary assumption.

Relationship between culturable airborne bacteria concentrations and ventilation systems in underground subway stations in Seoul, South Korea

In this study, we evaluated the concentrations of culturable airborne bacteria (CABs) in the underground environment of 16 subway stations in Seoul, South Korea. The effects of environmental factors on CAB distributions and concentrations, including temperature, relative humidity, depth, year of construction, number of subway passengers, and ventilation, were investigated. Tryptone soy agar was used as the culture medium. Isolated bacteria were initially characterized according to cell morphology and Gram staining and then further characterized using the VITEK 2 XL microbial identification system. There were significant correlations between CAB concentrations and station temperature, depth, and construction year. Micrococcus and Staphylococcus species accounted for 66 % of the total number of CABs identified. CAB concentrations in stations with ventilation systems were significantly lower than those in stations without ventilation systems (p < 0.001). Thus, it is critical to develop techniques to improve indoor air quality in subway stations with no ventilation system.

Temporal and Spatial Variations in Fine and Coarse Particles in Seoul, Korea

Concentrations of fine (PM2.5) and coarse (PM10–2.5) particles, whose aerodynamic diameters are less than or equal to 2.5 µm, and greater than 2.5 and less than or equal to 10 µm, respectively, at ambient air monitoring stations in Seoul between 2002 and 2008 were analyzed. Effects of Asian dust are mainly manifested as concentration spikes of PM10–2.5, but were considerable on PM2.5 levels in 2002 when Asian dust storms were the strongest. Excluding the effects of Asian dust, annual average PM2.5 showed a downward trend. Despite a similarity in year-to-year variations, PM10–2.5, mostly affected by fugitive dust emissions, and CO and NO2, primarily affected by motor vehicle emissions, did not show a decrease. PM2.5 along with CO and NO2 had peak concentration during the morning rush hour; the PM10–2.5 peak lagged one hour behind the PM2.5 peak. On high PM2.5 days, PM2.5 peaks occurred two hours later than usual as the effects of secondary formation through photochemical reactions became more important. A test for the spatial variability shows that PM10–2.5, which is known to be greatly influenced by local effects, is lower in its correlation coefficient and higher in its coefficient of divergence (COD, which serves as an indicator for spatial variability) than PM2.5, albeit by only a small difference. The average COD of PM2.5 among monitoring stations was about 0.2 but was lowered to 0.13 when considering high PM2.5 days only, signifying that spatial uniformity increases due to the pervasive influence of photochemical reactions.

도시철도 지하역사 냉방 기류 및 냉방 효율을 조사하기 위하여 수치해법을 이용하여 해석하고 현장 실험 결과와 비교하여 분석하였다. 해석 대상 역사로는 지하 8층의 깊이 43.6m인 서울 5호선 신금호 역사를 선정하였다. 전체 역사를 해석 영역으로 하였으며, 공조기 모드는 평상시 모드로 고정시켰다. 냉방 공조를 위하여 대합실 천정에 총 94개의 정사각형(<TEX>$0.6m{\times}0.6m$</TEX>) 환기구를 모델하였으며, 승강장은 총 222개의 환기구가 승강장 천정에 모델되었다. 대합실에서 급기되는 공기는 <TEX>$47,316m^3/h$</TEX>, 배기되는 공기량은 <TEX>$33,980m^3/h$</TEX>이며, 승강장에서 급기되는 공기는 <TEX>$33,968m^3/h$</TEX>, 배기되는 공기량은 <TEX>$76,190m^3/h$</TEX>로 현장의 풍량을 반영하였다. 승강장에서 스크린도어(PSD)는 닫힌 경우와 열린 경우 각각을 조사하였다. 총 750만개의 격자가 사용되었으며, 전체 영역을 22개의 다중 블록으로 나누어서 계산하고, MPI를 이용하여 각각의 블록에서 계산된 결과를 교환하였다. LES 기법을 이용하여 운동량 방정식 및 에너지 방정식을 계산하였다. Numerical prediction methods were applied to investigate the turbulent air currents and air-conditioning efficiency in an underground subway station, and the results compared to experimental data. The Shin-gumho Station(<TEX>$8^{th}$</TEX> floor underground and 43.6m in depth) in Seoul was selected for the analysis. The entire station was covered for simulation and the ventilation mode was ordinary. The ventilation diffusers were modeled as 95 square shapes of <TEX>$0.6m{\times}0.6m$</TEX> in the lobby and as 222 square shapes in the platform. Cooling air of <TEX>$47,316m^3/h$</TEX> was supplied and the returned air of <TEX>$33,980m^3/h$</TEX> is exhausted in the lobby and the cooling air of <TEX>$33,968m^3/h$</TEX> is supplied and the returned air of <TEX>$76,190m^3/h$</TEX> was exhausted in the platform which is the same as the experimental data. The cases of the screen-door-closed and open were respectively investigated. A total of 7.5million grids were generated and the whole domain divided into 22 blocks for MPI efficiency of calculation. Large eddy simulation (LES) was applied to solve the momentum and energy equation.

빗물펌프장 조기가동에 따른 도시 내수침수 저감효과 분석

In low-lying districts of urban areas, drainage pumping stations were built to protect urban inundation by the heavy rain and, in the station, the pump operation is performed by only reservoir depth. But the effect of pump operation can be improved by various pump- ing rules. This study would like to analysis the reduction effects of urban inundation by early operation of pumps. The various design rainfall events were applied to Gasan 1 pumping station in Seoul and then, the most effective period of early operation was 10 min- utes. Also, the maximum water levels of reservoir simulated by early pump operation were 10~70 cm lower than results by the exist- ing operation rule and the overflow volumes in upstream sewer network were reduece by about 50%. Therefore, in urban areas, the flood control stability can be improved by efficient operation of the existing pumping station.

Effect of platform screen doors on the indoor air environment of an underground subway station

Contaminant concentrations in a subway station in Seoul, Korea before (March 2008) and after (March 2009) the installation of platform screen doors (PSDs) were measured to investigate the effect of the PSD system on the subway indoor environment. PM10, CO2 and NO2 concentrations were measured at the platform, concourse and tunnel areas, using an indoor air quality tele-monitoring system (IAQ-TMS) operated by the Korean Ministry of Environment. Spatial correlations of contaminant concentrations at different locations were analysed, to investigate the effect of PSD installation on the movement of contaminants through air passages between zones. The results indicate that PM10 concentrations at the platform were reduced significantly after PSD installation and were within the guideline limit. The R2 value for the platform–tunnel correlation was reduced, indicating that in the absence of PSD, a significant amount of particulate matter was introduced to the platform from the tunnel. Conversely, the CO2 level in the platform was increased slightly after PSD installation, exhibiting a strong correlation with the number of passengers in the station. NO2 was predominantly introduced to the platform from the outdoor environment, on the basis of the source characteristics and their movement through air passages. This paper provides the data to develop a pollution management guide to control air quality contaminants in subway stations.

Behavior of particulate matter during high concentration episodes in Seoul

The behavior of particulate matter (PM) during high-concentration episodes was investigated using monitoring data from Guui station, a comprehensive air monitoring station in Seoul, Korea, from January 2008 to March 2010. Five non-Asian dust (ND) episodes and two Asian dust (AD) episodes of high PM concentrations were selected for the study. During the ND episode, primary air pollutants accumulated due to low wind speeds, and PM2.5 increased along with most other air pollutants. Particles larger than PM2.5 were also high since these particles were generated by vehicular traffic rather than wind erosion. During strong AD episodes, PM10-2.5 primarily increased and gaseous primary air pollutants decreased under high wind speeds. However, even during the AD episode, PM2.5 and gaseous primary air pollutants increased when the effects of AD were weak and wind speeds were low. This study corroborates that accumulation of air pollutants due to a drop in surface wind speed plays an important role in short-term high-concentration occurrences. However, low wind speeds could not be directly linked to local emissions because a significant portion of accumulated air pollutants resulted from long-range transport.

A Study on the Characterization of Deposited Dust on HVAC Ducts in Subway Stations

This study used various methods to evaluate duct cleanliness and identify the levels of deposited dust in the HVAC systems of subway stations, as well as identifying the characteristics of the pollution sources at the stations. Levels of deposited dust were determined in two subway stations in Seoul from September 2011 to January 2012. The levels of dust deposited on ducts of the stations were measured by visual inspection, the quantitative vacuum test (VT), and the deposit thickness test (DTT). The VT results confirmed that no subway station exceeded a dust deposit of 1.0 g/㎡, which is the recommended surface contamination limit when using the VT method. However, in some supply ducts, the thickness of the dust layer exceeded 60.0㎛, the recommended surface contamination limit when using the DTT method. The visual inspection indicated that platform pollution in subway station A was higher than in the HVAC and waiting rooms, but the difference was insignificant (p = 0.852). At subway station B, the waiting room had a slightly higher level of deposited dust, but the difference was insignificant (p = 0.438). The inspected areas were divided into HVAC rooms, return lines, and supply lines according to ventilation type. Although all three inspections revealed that return lines had the highest levels of deposited dust, the difference was insignificant. The correlation between the results of the visual inspection and VT methods, and between the results of visual inspection and DTT methods were both significant (p >0.01) with r = 0.815 and 0.818, respectively. It was confirmed that the results of a qualitative visual inspection method corresponded relatively well with the results of the quantitative VT and DTT methods. Analyses of eight heavy metals in the HVAC systems of the subway stations indicated that the inclusion ratios of iron (Fe), zinc (Zn), and magnesium (Mg) were 80.75–93.6%, 2.94–15.64%, and 1.63–1.82%, respectively. Traces of other heavy metals (As, Cd, Cu, Pb, and Cr) were also detected.

자동기상관측소의 국지기후대에 근거한 서울 도시 열섬의 공간 분포

Urban Heat Island (UHI) intensity is one of vital parameters in studying urban boundary layer meteorology as well as urban planning. Because the UHI intensity is defined as air temperature difference between urban and rural sites, an objective sites selection criterion is necessary for proper quantification of the spatial variations of the UHI intensity. This study quantified the UHI intensity and its spatial pattern, and then analyzed their connections with urban structure and metabolism in Seoul metropolitan area where many kinds of land use and land cover types coexist. In this study, screen-level temperature data in non-precipitation day conditions observed from 29 automatic weather stations (AWS) in Seoul were analyzed to delineate the characteristics of UHI. For quality control of the data, gap test, limit test, and step test based on guideline of World Meteorological Organization were conducted. After classifying all stations by their own local climatological properties, UHI intensity and diurnal temperature range (DTR) are calculated, and then their seasonal patterns are discussed. Maximum UHI intensity was <TEX>$4.3^{\circ}C$</TEX> in autumn and minimum was <TEX>$3.6^{\circ}C$</TEX> in spring. Maximum DTR appeared in autumn as <TEX>$3.8^{\circ}C$</TEX>, but minimum was <TEX>$2.3^{\circ}C$</TEX> in summer. UHI intensity and DTR showed large variations with different local climate zones. Despite limited information on accuracy and exposure errors of the automatic weather stations, the observed data from AWS network represented theoretical UHI intensities with difference local climate zone in Seoul.

The size of the station influence area in Seoul, Korea: based on the survey of users of seven stations

This study aims to identify the size of the station influence area (SIA) in Seoul, Korea. For this study, a survey of 100 passers-by per station was conducted after choosing seven railway stations in Seoul. The general size and walking distance of an SIA are identified as 462 and 376 m, respectively. The time required from stations to destinations is identified between 7 and 10 min. The results appear similar to a series of findings in the advanced countries but are fairly decreased, particularly in terms of walking distance, compared with the results found in existing Korean studies. Meanwhile, walking accounts for about 80% in terms of the travel mode employed to destinations. In choosing the travel mode to destinations, station users consistently value many of ‘utility factors’ such as economic feasibility and time required over ‘livability factors’ such as environment and amenities, regardless of trip purpose, age, gender, occupation, and income level, although the margin is not great. There is no noticeable difference in the size of SIA and the time required from stations to destinations between three-tier centres classified by spatial hierarchy.

Axes of urban growth: urbanization and railway stations in Seoul, 1900–1945

The urban space of Seoul that had kept the structure of the Fortress and the Seongjeo Shibri for more than 500 years began to be transformed with the introduction of modern transport facilities, the railway and tram, in the early twentieth century when Seoul became the colonial capital of Gyeongsung-bu. The railway station buildings that were constructed in the main areas of Gyeongsung-bu mirrored international developments through taking charge of the city's passenger traffic and cargo distribution. They also influenced greatly the course of the city's urban growth. This article investigates the features of the urban growth of Gyeongsung-bu through looking into changes in the station buildings' role and into the construction of railways, which became the public transportation system throughout the whole Korean Peninsula.

승객 수요 패턴과 역세권의 토지이용 특성을 반영한 도시철도역 첨두시간 집중률 산정 - 서울시를 대상으로 -

본 연구는 역사의 승객수요 패턴과 토지이용 특성을 반영하여 도시철도역 승객의 첨두시간 집중률을 산정하는 방법론을 제시하는 것을 목적으로 한다. 이를 위하여 요인분석과 군집분석을 기반으로 서울시 도시철도 역사를 3개의 그룹으로 분류한다. 각 그룹별로 이용수요의 첨두시간 집중률과 함께 도시철도 승객수요 패턴과 역사의 토지이용과 관련한 5가지 변수와 4가지 변수를 각각 산출한다. 통계 검정을 기반으로, 이 변수들 중 일평균 승객수와 업무 LQ지수가 역사의 그룹을 구분하는 기준으로 선정된다. 두 변수들을 활용하여 새로 건설되는 도시철도역의 첨두시간 집중률을 추정하기 위한 그룹할당과정을 제시한다. 13개의 도시철도역 자료를 이용한 검증을 통해 본 연구의 방법론은 현재 이용되는 지침에 비하여 더 적은 오차를 산출할 수 있다는 것을 확인하였다. 본 연구의 방법론은 신규 철도역사의 효율적인 건설 및 운영계획 수립에 기여할 수 있을 것으로 사료된다. The aim of this study is to suggest a methodology for calculating the peak-hour ratio of passengers at urban railway stations by reflecting the characteristics of passenger demand patterns and the land use inventory of stations. To achieve this, urban railway stations in Seoul are divided into three groups by using factor analysis and cluster analysis. For each station group, we calculate five and four variables related to the passenger demand patterns and the land use inventory of stations, respectively, as well as the peak-hour ratios of passengers. Among these nine variables, average daily passengers and the location quotient (LQ) index for business services are selected as the classification criteria for station groups based on statistical tests. Using the two variables, a group allocation process is suggested to estimate the peak-hour ratio of passengers for a newly-constructed station. Evaluation results based on thirteen stations show that the proposed methodology produces lower errors than the currently-used guideline does. The results of this study contribute to establishing efficiently construction and operation plans for newly-constructed stations.

Simultaneous monitoring of total gaseous mercury at four urban monitoring stations in Seoul, Korea

The monitoring of total gaseous mercury (TGM) concentrations together with other trace gases and meteorological parameters was made at hourly intervals over 2-year period (1 January 2010 to 31 December 2011) at four urban monitoring sites: Guro-gu (G), Nowon-gu (N), Songpa-gu (S), and Yongsan-gu (Y) in Seoul, Korea. The mean concentrations of TGM at these sites were found to span the range of 3.28 (Y) to 3.47ngm−3 (N). Inspection of the seasonal patterns indicates that the maximum concentrations (ngm−3) occur at different times of year across the four sites: winter at N (3.67±1.77), fall at S (3.64±1.12), summer at G (3.61±1.51), and spring at Y (3.40±1.26). The long-term trend in Hg concentrations, when also considering data sets from previous studies, suggests modest reductions in concentrations at all four sites, from 2.89 to 4.49ngm−3 in 2004 and from 2.49 to 3.42ngm−3 in 2011.

A New Approach for the Evaluation of the Walking Environment

ABSTRACT Space, flow rate, speed, and the volume-to-capacity ratio have been taken into account in the existing evaluations of pedestrian environments, such as those focusing on traffic facilities. However, these measures are insufficient when assessing pedestrian environments in favored places where many pedestrians congregate. Therefore, this study attempts to develop a “walk score” to evaluate the spatial characteristics of pedestrian environments and the facility characteristics of pedestrian networks in relation to major subway stations in Seoul, Korea. In particular, the walk score that we have developed focuses on qualitative convenience factors using GIS (Geographic Information System) and quantitative network connectivity indices of the Space Syntax technique. The scores of the amenities have been calculated as avenue-oriented type, destination-oriented type, or general amenities, considering the individual distances and the number of facilities available. The convenience and connectivity of the pedestrian networks have been measured quantitatively using the Space Syntax model (Hillier 1996; Penn et al. 1998). Furthermore, our walk score has been calculated by integrating amenity and pedestrian network scores using the Analytical Hierarchy Process (AHP). With the walk score proposed in this study, it is easily possible to evaluate pedestrian environments around subway-adjacent areas, and to compare and analyze the types and number of facilities and the connectivity of the pedestrian networks. This will be helpful in suggesting future improvements, as well as evaluating the level of quality of current pedestrian environments.
