To effectively reduce PM10 generated in concourses and platforms of subway stations, a research is being conducted to find the PM10 source. The main source of PM10 in subway stations was PM10 generated in the main line tunnels, which was generated in proportion to the frequency of the train operation. Each amount of the PM10 generated when the train was operated once, was constant regardless of the time. On the assumption that the PM10 level in a tunnel of a line is a sum of newly generated amount of dust when the subway passes and the amount carried from the adjacent stations by the wind generated from the subway rolling stocks, the method which estimates the intensive PM10 occurring section was developed and applied to the 12 stations between Cheongdam and Jangseungbaegi in Seoul Subway Line 7.

In this paper, a distributed evacuation system based on the positioning information of subway passengers is proposed. Recently, the subway station is becoming complicated by combining with shopping malls, and movie theaters. Compared to the increasing complexity of subway stations, evacuation systems are less complex. Subway passengers in each cell were estimated to use the access point in the subway cells and statistics information. The evacuation route is provided through a direction indicator and push alarm of a smart phone based on estimated the number of passengers and exit information of the subway station. Based on this schemes, a quick and safe evacuation system of subway passengers was proposed. The number of connection passengers was estimated using AP with OpenWrt embedded OS installed. The average error rate of the number of passenger was confirmed to be 15%, 17% and 23% at the confidence parameter of $1{\sigma}$, $2{\sigma}$, and $3{\sigma}$, respectively, through a simulation. The possibility of the system through a simple experiment was examined.

Detour of metro (subway) in metropolitan area has been regarded as one of inherent elements that make entire metro system less competitive than passenger cars. However, factors affecting detour of metro line is not specified clearly when a new subway system is planned or an existing system is improved. Previous detour-related studies was reviewed for developing 'distance efficeincy evaluation model' for metro as well as its counterpart (i.e. road). Metro line 3 (orange line) of Seoul metropolitan area was applied as a case study. As a results, the most detoured OD segment is Daechi - Apgujeong and its detour factor is 1.93 which means that the distance of the metro is 1.93 times longer distance compared to the distance of the road. The metro line 3 has averagely 20% longer distance compared to road for the identical O/D pairs.

In accordance with low carbon and green growth paradigm, a subway is one of major public transit systems for resolving traffic congestion and decreasing traffic accidents. In addition, as subway networks expand, passengers' travel pattern in the subway network change and consequently affect the urban structure. Generally, new subway route has been planned and developed, mainly considering a travel demand forecast. However, it is desired to conduct an empirical analysis on the forecast model regarding change of travel accessibility and passenger demand pattern according to new subway line. Therefore, in this paper, an alternative method, developed based upon a spatial syntax model, is proposed for evaluating new subway route in terms of passenger's mobility and network accessibility. In a case study, we constructed subway network data, mainly targeting the no 9 subway line opened in 2009. With an axial-map analysis, we calculated spatial characteristics to describe topological movement interface. We then analyzed actual modal shift and change on demand of passengers through the number of subway passenger between subway stations and the number of passenger according to comparative bus line from Smart Card to validate suggested methods. Results show that the proposed method provides quantitative means of visualizing passenger flow in subway route planning and of analyzing the time-space characteristics of network. Also, it is expected that the proposed method can be utilized for predicting a passengers' pattern and its impact on public transportation.

서울의 지하철은 하루 450만 명이 이용하는 중요한 대중교통수단임에도 불구하고 역구내의 먼지에 대한 단순 측정ㆍ분석만이 이뤄지고 있을 뿐 그 먼지의 생물학적 영향에 대한 연구는 미흡한 실정이다. 본 연구에서는 지하철역 구내에서 포집한 먼지가 돌연변이원을 함유하고 있는 지를 평가하였다. 신촌역 지하철입구, 대합실, 승강장에서 포집한 총부유분진 (TSP; total suspended particulates)을 용매에 용출시켜 공시재료로 사용하였다.(중략)

지난 4월 22일 발생한 북한의 룡천역 폭발사고로 인하여 사망자수 150여명, 부상자수 1,300여명에 달하는 엄청난 재해가 발생하였다고 전해지고 있다. 룡천역을 중심으로 반경 500m 파일이 완파되었으며, 폭발 영향권도 4km에 달하였고 반경 500m 안에는 역사와 학교 및 4-5층 규모의 아파트가 다수 있었기에 피해 규모가 더욱 컸다고 알려 졌다. 1990년대 들어 우리나라도 심대한 대형 재난사고를 당하였다. 성수대교 붕괴(1994), 대구지하철 공사장 가스폭발(1995), 삼풍백화점 붕괴(1995), 대구지하철 화재(2003) 등 잇따른 대형 참사는 우리의 위기관리 현실을 되돌아보게 하였고, 국민들은 언제 발생할지 모를 재난에 대한 불안감으로 그 어느 때보다 안전한 나라에 대한 열망이 강한 것이 사실이다.(중략)

The population is increased in the area of a subway station because the accessibility of passengers is improved. Therefore, facilities for commercial purpose are concentrated in this area. To develop the station area as the center among the most urbanized area, overall mater plan should be constructed far the station area. This study was to construct web server for management a variety of 3D spatial object database of station areas using GIS and web 3D technology. These results will be used to manage efficiently a urban space by the connection of a subway station and a adjacent facilities.
