There have been recently introduced new types of urban metro vehicles called LRT (Light Rail Transit) running on elevated guideway such as Uijeongbu VAL(which stands for V$\acute{e}$hicule Automatique L$\acute{e}$ger: Automatic Light Rail Vehicle) system, Yong-In LIM(Linear Induction Motor) system, Incheon international airport MAGLEV(Magnetic Levitated Vehicle) system and Daegu monorail system. Most of accidents by the vehicles are bound to happen on elevated guideway. Therefore, it is of vital importance to analyze hazards related to vehicles running on elevated guideway and study emergency evacuation scenarios applicable in case of accidents on elevated guideway so as to secure the safety of the new types of urban metro vehicles. In this study, FTA(Fault Tree Analysis) model was developed to identify all possible hazards, and all possible evacuation scenarios were studied. It was also confirmed that each hazard can be corresponded to one or more evacuation scenarios. This result shows that passengers can be evacuated according to one of the scenarios identified in this study in case of an accident of "Train Stranded on Elevated Guideway".

The structures for road safety are guard rails that protect the cars and passengers. If an accident occurs on the roads after a long period of installation, it may escalate into a major disaster. In order to repair many guard rails, the existing repair method of replacing them with new ones requires enormous financial resources. To solve this problem, the G-SAVE method was developed to repair the guard rail without replacing them. This method removes the rust on the surface of the guard rail and then performs ambient-dip galvanizing coating on it without replacing the new ones. No studies or reports have yet been made on the risk assessment of harmful substances, vehicles for these entire processes. Therefore, this paper focuses on risk assessment using the PHA (Preliminary Hazard Analysis) technique and conducts risk assessment for concept design stage of the coating vehicles.

비상대응계획은 사고의 예방보다는 신속한 대응을 통하여 인적 물적 피해를 최소화 하기 위한 목적으로 설계된다. 그러나 매뉴얼 작성 및 운용을 위하여 많은 노력과 비용을 지출함에도 불구하고 이의 효용성에 대한 논란은 계속되고 있다. 매뉴얼의 다양한 종류, 복잡함으로 인한 활용도 저하, 이해의 어려움, 비 현실성, 의사 판단의 제약, 상시 협력 부족 등과 관련된 많은 논란의 시작은 법에서 정하는 다양한 매뉴얼의 종류와 그 구성 내용의 상이함에서 비롯된다. 국내외 철도와 관련된 법률에서 철도운영기관 입장에서 마련하여야 하는 매뉴얼의 종류와 그 내용을 분석한 결과 2개의 법률인 '재난 및 안전관리 기본법'과 '철도안전법'에 따라 서로 다른 형태의 매뉴얼을 각각 마련해야 하는 문제가 있다. 이러한 법에 따라 철도운영기관이 모든 매뉴얼을 각각 작성 운영하는 것보다 한 개의 법(철도안전법) 적용으로만 한정하여 중복된 매뉴얼 생성 및 관리의 책임을 경감시킬 필요가 있다. 내용의 구성에서도 사고유형별, 위기수준별, 위치 별로 구분하여 비상 대응 내용에서의 불필요한 중복을 줄일 필요가 있고, 실제 사고에서 우선적으로 활용되는 내용들을 토대로 시간 순서에 따라 재구성 하는 방안을 제시함으로써 매뉴얼의 활용 성을 높일 수 있을 것이다.

The accident fatality rate has decreased by more than 90% compared to 2006, due to the safety management and safety investment based on the Rail Safety Act. Most railway safety indicators, including fatality rates, have improved significantly from 60% to 80%, reaching the level of developed countries in terms of most railway safety indicators. However, the only staff fatality rate at work is not improved, and it is 3 to 5 times higher than that of developed countries. Most of the fatality occurred during employee's work recently occurred due to accidents hit by train while track work. In principle, when operating track need to check or maintenance, the operation of the train should be stopped and the work carried out. However, in Korea, due to the highest passenger density and train operating density in the world, it is caused by a structural problem that requires workers to enter the track while the train is running and perform various tasks such as maintenance and inspection. In this study, we analyzed the risk of accidents caused by hit by trains on the track, which is the biggest cause of staff fatality, using the main statistics of the last 10 years. In detail, the scenarios of the main causes of hit by trains and workers were formed to suggest the effectiveness of the current preventive measures and supplementary.

NATM as method of tunneling has been applied to construction of domestic subway, roads, rail way, water way etc. Accordingly, we have NATM's many drafts and constructional results, but many problems and accidents have occurred under construction of tunnel using NATM for shortage of technical data. Poorness of constructional improvement, systemic inconsistency etc. Especially, everyone was shocked at Gupo's train wrecking accident lately. The purpose of this thesis is presentation of means for setting technical problems, by looking into Gupo's train wrecking accident and home records that applying NATM in tunneling failed, to minimize future safety accidents we find that the general problems of home fifteen sites having occured accidents is badly geological survey, nonconfirmationi of base rock's state, formal measuring management, shortage of specialists, systemical discrepancy and that disregarding NATM's rules makes general problems. The results of this study are Summarised as follows : 1. We advise repletion of design standards to practice crosshole test for confirming connected rock base on vertical section of tunnel. 2. We advise to practice pre0boring and pre-grouting for a weak layer difficult in applying NATM. 3. We advise systemic improvements that field servicer can construct tunnel of his own free will considering base rock's state at tunnel . 4. We advise that specialist, who can make a conduct and supervise above mentioned items as well as measuring management, should be posted at field.

Recently heavy traffic is getting worse because increasing population of transportation in urban area. In order to solve this problem. subway is realized with high speed, high density, highly efficiency. When fire accident happened in Dae-Gu subway in February 2003, there happened loss of people and lots of damage because of not being able to control even though fire alarm which was set up in the station rang. This thesis has constructed a simulation integrating operation system using a Database construction, operating program analysis in order to build up the most efficient train operation system. The result of simulation integrating operation system with emergency virtual situation like station and train fire, train failure, power line failure, all trains running on the rail were secured safety by train operation control system. With integrating operation of each train control system, train system, power system, machine facility system, the most efficient integrating operation system should have been constructed at the time the subway fire and power failure broke out.

1974. 8.15 SeoulMetro, beginning with the first electric railway established at six cities, so it is managing mass transportation of traffic. Especially, in case of seoul, It is managing that from one to eight lines, 286.9km, 265 stations have installed and now it is carrying about 5.5million of passengers everyday, and 2,000million passengers a year. So accident is increasing from the station every year. For this measure, SeoulMetro prepares safety fence for passengers crash but, as suicides or people who watch the accident took place, for at the bottom of passengers crash protection, PSD installing is needed. Even though, PSD is managing ATO section but, in controlling SeoulMetro, one to four lines sections are (ATS, ATC)section. Between as ATS, ATC section, ATO section, subway gate and PSD must have opened and crossed always at the time. And the interlock control corrosion protection gate, managing skills with installation, method, using in history, apply to 10rail cars one train sets, and maximum applying 224% sections of passengers congested that consideration is to be needed. So 2004, SeoulMetro improved technology and basic design of PSD at ATS section. Based on this, from 2005.4 to 2006.6, using subway 2lines per 12stations set the model installation(full type 11stations, half type 1station) After installing in case of success, it is going about to suggest that effective analysis and hereafter subject.

본 연구는 (예비)타당성조사의 교통사고 감소편익 산정방안에 관한 개선연구이다. 기존 방법론의 문제점은 크게 네 가지로 살펴볼 수 있다. 첫째, 인적피해사고 구분이 사상과 부상으로 단순화되어 있다. 본 연구에서는 현행 법 규정에 충실하게 도로는 사망, 중상, 경상 및 부상신고 사고로 구분하고, 철도는 사망, 중상 및 경상사고로 세분화한다. 둘째, 인명피해가 없는 단순 대물피해사고에 대한 고려가 미흡하다. 본 고에서는 대물피해사고를 사고유형의 하나로 명시적으로 고려하고 관련 사고비용원단위를 추정한다. 셋째, 사고비용 원단위가 단일 총액으로만 제시되고 있다. 사고비용을 구성하는 항목은 다양하므로 개별 항목은 특정 정책 수립 시 유용하게 활용될 수 있다. 본 연구에서는 사고비용을 생산손실비용, 의료비용, 물적피해비용 및 행정비용으로 세분화한다. 넷째, 도로와 철도의 사고비용 추정방안에 일관성이 결여되어 있다. 도로는 고속국도, 일반국도, 지방도 등 시설의 서비스 등급별 사고비용을 산정하는 반면 철도는 여객과 공중으로 구분하고 있다. 본 연구에서는 철도 서비스 등급별 사고건수 및 사고비용 원단위를 제시한다. 본 연구의 결과로 보다 합리적인 경제성 분석을 수행할 수 있음은 물론 궁극적으로 보다 신중한 사회기반시설 투자 정책 수립에 일조할 수 있기를 기대한다.
