대도시권에서 지하철의 우회는 승용차 통행에 비해 지하철의 경쟁력을 떨어뜨리는 요인으로 지적되어 왔다. 그러나 새로운 지하철 시스템을 계획하거나, 기존의 운행 노선을 개선할 때 다른 가치들 (영업이익, 수요, 노선의 균등 분배 등)과의 관계에서 우회에 대한 최소기준 정도만 존재할 뿐 다른 가치들과의 가중에 대한 기준이 모호한 실정이다. 이 연구는 우회의 개념을 사용하여 수도권 지하철의 거리 효율 평가 모형을 다루고 있다. 연구의 목적은 지금까지의 우회율과 관련된 선행연구들에 대해 요약을 하고 새로운 거리 효율 평가 모형을 만들어보며, 이 모형을 수도권 지하철 3호선에 적용하는데 있다. 주요 결과는 두 가지로 나눠볼 수 있다. 첫째, 가장 크게 우회하는 OD는 '대치'역부터 '압구정'역까지였으며 우회계수는 1.93으로 나타났다. 이는 도로의 네트워크보다 약 1.93배 더 길게 우회하는 것을 의미한다. 한편, 수도권 지하철 3호선을 전체적으로 분석을 해본 결과, 도로의 네트워크보다 평균적으로 약 20% 더 우회하는 것으로 나타났다.

본 연구는 동적 시각화 방법을 토대로 서울 대도시권 지하철 통행흐름의 요일 간 변동성을 분석한다. 이를 위하여 본 연구에서는 수도권의 1주일치 교통카드 자료에서 요일별로 1분 간격으로 지하철 승객흐름을 추출한다. 지하철망상의 통행흐름의 시공간적 분포를 나타낼 수 있도록 동적 시각화 방법을 고안하여 지하철 승객의 시공간적 분포에 나타나는 요일 간 변동성을 직관적으로 분석한다. 그 결과로 주중과 주말 지하철 승객흐름의 시공간적 분포 패턴은 확연한 차이를 보인다. 주중과 주말에도 요일에 따라 다소 다른 양상을 보인다. 서울의 주요 중심업무지역들과 유흥지역들의 승객흐름에도 요일별 승객흐름 양상에 뚜렷한 차이가 있음을 확인할 수 있다. 이러한 분석결과는 도시계획과 교통계획의 토대가 될 뿐 만 아니라 도시 재해 재난이 발생할 경우 피해에 노출되는 인구규모를 파악하고 신속한 대피대책마련에 유용한 정보를 제공할 수 있다.

본 연구를 아우르는 질문은 "지하철 역사내부를 이동하는 개별승객은 언제 어디서 어떤수단을 이용해서 출발해서 언제 어디로 어떤 수단을 이용해서 갔는가 ?"이다. 이 물음에 답하기 위해서는 지하철 역사를 이동하는 개별승객이 이용한 정류장, 경로, 수단에 대한 파악이 선행되어야 한다. 수도권 통합대중교통요금체계에서는 AFC(자동요금징수체계)자료를 활용하면 개별대중교통이용승객의 통행수단, 정류장, 경로가 파악된다. 본 연구는 AFC자료를 이용하여 수도권의 대중교통역사의 승객이동을 지하철 환승역사의 관점에서 관찰하는 SSA(선별역사분석) 기법을 제안한다. SSA는 환승역사내 개별승객이동을 세분화하고 연계통행관점에서 최초출발역/시간과 최종도착역/시간 정보를 분석한다.

The purpose of present study is to find design parameters and operating conditions of the HVAC system in a subway platform. The simulation was carried out for the flow, heat and mass transfer for heating, ventilating and air-conditioning(HVAC) environments in the subway platform. The steady-state. incompressible flow assumption and standard $k-{\varepsilon}$ turbulence model are adopted. The location of HVAC air inlet above platform and the volume flow rate of curtain air released from inlet B are chosen as main parameters in this study. The results of present study are following: In the case of existence of train, the heat and contaminant released under the train have no effect on the average temperature and mass fraction of contaminant in the platform, but heat released on the train has influence on the average temperature in the platform. Train acts as an obstacle to exhaust the contaminant in the platform, but has good effect on the average temperature in the platform.

A study on fire phenomena in a subway transit mass station has been carried out as a part of disaster prevention plan at the subway station. The ventilation facilities installed in both the platform and the trackway are designed to convert into a smoke exhaust system in emergency situation, creating an environment necessary for evacuation. 3 dimensional Numerical Simulations based on the CFD are carried out using a simulation tool, Fire Dynamic Simulator. Total of six different cases are made and performances are compared each other to find optimal vents operation to ensure safer environment for evacuation at the platform area considering the installation of platform screen door.

In this research, we investigate the method to support decision making of researcher when they estimate the safety on the subway using AHP of Saaty. To apply this technique, we apply to subway system. The AHP suggested by Saaty in 1971 is a tool to support a decision-making including the personal opinion and intuition, and it is easier than other method. Then, it has an advantage that control the complex object having multiple criteria simply. And we suggest the eight stage of accident type and the five criteria that must meet. Based on AHP, we concluded a safety in subway is more important factor than any other factors including economic points of view.

Indoor air quality is an important determinant of human health and comfort. However, the complexity of pollution sources and the multitude of parties responsible for creating indoor exposures makes the improvement of air quality difficult. The HVAC(Heating, Ventilating and Air-Conditioning) system is important facility to provide comfortable environment passenger service. The Ministry of Environment is established "Indoor Air Quality Management guidelines in Public Facilities"in December 2006. Hereupon, the train and the subway are included. In this research air quality in the Subway compartment has been measured. As a result, the concentrations of PM10 and $CO_2$ were reached to 93% and 61% of the regulation values, respectively. Thus, the indoor air qualities of subway have been proved that they satisfy the recommended guidelines by the Ministry of Environment.

In our modern society, such electric facilities as lighting, elevators, water supplies, drainages, waste water treatments and landscape lighting are being more enlarged, diversified and technology-intensive owing to outstanding technological development, while they require reliable and safe electricity. On the other hand, as more electric energy is consumed with more complicated systems operated, any accident from a personal electric system is likely to have wider spreading effects. In particular, the electric receivers and transformers installed for such public facilities as subway stations require highest safety, reliability and economy, but such requirements tend to be less considered than such financial requirements as budget conditions, much less their safety and reliability. In such a circumstance, this study was aimed at suggesting some standards for safe, reliable and economic subway electric systems in terms of their scale, location and uses. Specifically, this study put forwards the ways to optimize and standardize the electric systems including receivers and transformers for subway stations in order to make them safer, more reliable and economic.

The rail, which supports the train road, distributes the wheel loads to the tie by rail stiffness. Subway sleeper on concrete ballast is construction of PC or RC sleeper. The present, PC sleeper is constructed of line 1, 2, 3, 4 Seoul Subway and RC sleeper is planing construction for the STEDEF system on concrete ballast of the line 5, Seoul, Taegu, and Kwangju Subway. The major purpose of this study is to check influence of the angle with analysising the behavior of sleeper according to the existent or non-existent of angle. And the study is carried to check static analysis by manufacture of same model.

The subway with the initial constructive expense which is enormous together is the public transportation means where the many expense is expended in the operation and maintenance civil official. Seoul Metro until initial opening to traffic after present time cannot escape every year deficit to be, the cause is a possibility of seeking from the fare system which is short in transportation prime cost. Currently Seoul Metro is operating with the distance proportional fare system the passenger ticket system which is simple (usual volume, group volume and fixed amount volume, affection renunciation, charge free volume). When the biased characteristic of the user it plans considering from the goods development side for the variety for and a deficit solution, against the fare system systematic it researches and solution plan politically. Financial of the subway operation agency young the investigation against the present condition of the hazard subway fare system which is solved the bud with problem point a fare system from the research which it sees consequently and improvement program under analyzing the man with underdeveloped genital organ. Base on the reporter to analyze the introduction plan which with the character which will reach it follows with the necessity of introduction of the 1st passenger ticket (24 hour volume).
