Particulate matter (PM) is one of the major indoor air pollutants especially in the subway station in Korea. In order to remove PM in the subway station, several kinds of PM removal system such as roll-filter, auto-washable air filter, demister, and electrostatic precipitator re used in the air handling unit (AHU) of subway station. However, those systems are faced to operation and maintenance problems since the filter-regeneration unit consisting of electrical or water jet parts is malfunctioned due to the high load of particulates and the filter material needs periodic replacement. In this study, we surveyed the particle removal systems in order to develop the new system of particle removing can be adopted in the current AHU of subway station.

A fire disaster is very serious in the closing space like subway station. In this study, the simulation on fire diffusion is performed to get the temperature history curve, which is used for the fire resisting structural analysis. Most of subway stations are built by the reinforced concrete structure, but recently steel structures are selected for the larger space or beauty. Steel structures relatively have more weaknesses against fire, so it is necessary to develop the method for evaluating fire-resisting capacity in this kind of structures. The developed method is applied to the subway station in Daegu city. It shows that the developed method can be used to simulate the fire disaster and to get the temperature history curve and evaluate the safety of steel structures against the fire.

This study analyzed whether a subway accessibility impact on house price is constant since its operation over time or not. The study was approached specifically to answer two research questions. One is "Are there significant temporal variations in the relationship between subway accessibility and housing price transacted after its opening?" The other one is "How the pattern of its temporal variation in housing price is formed as a function of the distance from the nearest station?" The study area is the subway station areas in the Daejeon metropolitan city, South Korea. Its first subway line has started to be opened in 2006 with 12 stations and then opened its additional 10 stations in 2007. It can be more appropriate to observe its impacts of subway accessibility on housing price because it has only one transit line with more than 10-year reaction term to its operation. The study employed alternative models to estimate yearly variation of subway accessibility on house price for the station areas with 500-meter and 1-kilometer radius respectively. While the study originally considered both a hedonic price model with interaction terms of its access distance to yearly transacted housing and a time-variant random coefficient model, the former model was finally selected because it is better fitted. Based on our analysis results, the reaction of house price to its transit line had significant temporal variation over time after opening. In addition, the pattern in its variation from our analysis results indicates that its capitalization impact on house price is over-estimated in its first several years after the opening. In addition, its positive capitalization impact is more effective in the 1000-meter station area than in the 500-meter one.

본 연구는 합리적인 역세권 범위를 설정하고 이에 미치는 요인을 규명하기 위해 CART(Categorical Analysis Regression Tree) 분석을 이용하여 4대 신도시(분당, 평촌, 일산, 산본)에 대해 SIA 모형을 개발하였으며, 그 결과를 요약하면 다음과 같다. 첫째, 지하철 역세권에 영향을 마치는 변수를 중심으로 상관관계를 분석한 결과, 역세권 지가에 영향을 미치는 주요요인이 도보거리로 나타났으며, 두 관계를 이용하여 SIA 모형을 개발하였다. 둘째, SIA모형식(선형식, 다항식)을 비교분석한 결과, 신도시별 역세권의 범위는 철도역사로부터 도보거리기준으로 분당 신도시가 856m, 일산 산본 신도시가 508m, 평촌신도시가 495m로 각각 다르게 나타났다. 셋째, SIA 모형간 계수를 비교분석한 결과, 철도역사로부터 도보거리가 가까울수록 지가에 대한 영향이 커지는 것으로 나타났다. 또한 신도시별로는, 분당 평촌신도시가 일산 산본 선도시 보다 도보거리에 대한 지가의 영향이 크고 지가 또한 높은 것으로 나타났다. 따라서 현행 도시철도법상 역세권 범위인 반경 500m 이내로 획일적으로 정한 역세권 범위기준은 불합리하며 신도시지역의 토지이용 및 보행접근성(도보거리) 특성을 반영하여 재설정하는 것이 바람직하다고 판단된다.
