To predict the fire and smoke hazards of rail car with a evacuation model is essential for achieving life safety of all passengers in the event of fire. Currently, more than 30 different evacuation models are available and expected increasing demand in high population density areas as a metro train station. This paper includes brief history of evacuation models and review some key factors of design egress scenario, these are pre-movement time, egress route, location of fire, overturned carriage, and configuration of rail car. Applying the egress model for rail passenger car, users need to confirm the model's ability of physiological, psychological responses effecting to pre-movement time of individual or crowd unit, representation of complexity of carriage layout, and evaluation of effects of smoke.

차량과 바퀴하단까지의 높이가 국내 차량의 경우 0.625m와 1.15m였으며, 외국의 경우는 지면까지의 거리를 1.3m 높이로 한 경우도 있다. 이 높이는 정상 성인의 경우에는 뛰어내리는 것이 가능하지만, 아동, 노인, 장애인에게는 어려우며 추가적인 시간 소요가 발생하게 된다. 일본 신건축방재지침에서 제안된 피난계산식을 통해 분석해본 결과 CAR A의 경우 유동계수 0.5에서는 123.1초, 1.0에서는 61.5초, 1.5에서는 41초를 나타내고 있다. 정상상태의 유동계수 1.5로 한 후 추가적인 시간을 더하면 298.6초의 시간이 소요되는 것으로 예측되었다.

본 논문에서는 교통카드 데이터를 활용하여 지역 간 철도역(서울역)을 중심으로 유입과 유출통행에 이용된 대중교통 수단을 중심으로 지역별 통행패턴을 분석하고 이들 통행에 대한 대중교통 수단선택의 문제를 도시철도와 버스로 구분하여 분석하였다. 서울역으로의 유출입 통행특성을 분석한 결과, 서울역으로의 유출입통행은 1번 이내의 환승으로 통행한 경우가 99%로 나타났다. 유출입 통행수단으로는 버스보다 도시철도를 이용한 비율이 높았으며 서울역에서 가까운 지역에서 버스의 이용율이 높게 나타났다. 버스와 도시철도의 수단선택 행태분석을 위해 이항로짓모형을 구축했으며, 그 결과 지역간 철도역유출입통행 수단선택에 있어 통행요금보다는 통행시간의 영향이 더 큰 것으로 나타났으며 특히 유출통행에서 매우 큰 영향을 가지는 것으로 분석되었다.

철도 차량에서의 화재 발생 시 피난에서 차량에서 승강장이나 터널 같은 외부 환경은 매우 중요하다. 많은 인원이 탑승하게 되는 지하철과 그 승강장의 영향을 알아보기 위해, SIMULEX, PATHFINDER, STEPS를 시나리오에 적용 비교해 보았다. 대상차량은 서울에서 운행되는 차량을 기준으로 하였으며, 대상 승강장은 [도시철도 정거장 및 환승 편의시설 보완설계지침]을 기준으로 제작한 모델을 적용하였다.

This study analyzed passenger's access modes that connect to regional railway station and developed a model of access mode choice based on transit smart card data of Seoul station as a case study. The study boundary includes sixteen bus stops around the station. The results show that most passengers access to station have less than two transfers. Of total 15000, eighty percent of passengers use metro and the rest of people take a bus. Interestingly, it is found that almost same proportions of passengers use metro and bus for egress the station. Consequently, metro is found to be most likely used mode compared to bus for both access and egress trips.

In case of rolling stock, SEMS is generally applied in the advanced countries, but is start stage in our country. SEMS is defined the system engineering management system in order to achieve the optimized train performance among the several client requirements aspect of technical engineering management during the design life cycle. And the fire engineering activities in hong kong EMU project are introduced aspect of SEMS in this paper. The fire engineering at rolling stock in view of SEMS controls to apply the satisfied interior material by the fire safety standards (regulation of the commute urban subway safety guideline by the MOCT, BS 6853, NFPA 130, NF F 16-101) and to minimize the fire load in order that passengers egress safe from the fired rolling stock. The rolling stock in the advanced countries is designed to stand for 15-20 minutes in considering the rolling stock to be fired in tunnel. For passenger fire safety, the passenger evacuation provision and progress is set up.

The Korean high-speed rail (HSR) began its commercial service in 2004. This service has been created significant changes in the system of intercity passenger travels of Korea. However, the actual ridership was approximately half of the estimated one in the planning stage. In this background, this paper presents the difference between the stated preference (SP) before the HSR service and the revealed preference (RP) after it using the intercity travel mode choice models. Several meaningful differences are found in terms of the factors affecting the travel mode choice, the estimation results of model, the monetary values of time, and elasticities. While the access/egress travel time of high-speed rail is less important than in-vehicle travel time in the SP sample, they have same weight in the RP sample. Also the RP models show that the probability of choosing HSR can be decreased by the increase of the number of vehicles in household contrary to the results from the SP models. The monetary values of travel time are relatively high and the direct and cross elasticities in response to changes in level-of-service of HSR are relatively low in the RP sample. This Korean case is expected to offer referable material for preparing high-speed rail services in other countries by showing the difference between the SP and RP before/after the actual service, identifying the importance of access/egress travel time and lower direct elasticities of HSR demand.

Heat/smoke detectors are installed in most subway platforms in Korea to detect fire. Subway platform is divided by smoke-control zones for efficient smoke-control. Once the detectors detect heat or smoke, the smoke-control ventilation system in the platform and concourse is activated according to the smoke-control ventilation mode. Smoke-control mode during fires in Korean subway platforms is that the smoke zones operate by exhausting smoke while other zones in the platform and in the concourse which is the upper floor of the platform operate by supplying air or stopping any ventilation. This study is conducted to evaluate performance of passengers' evacuation for various smoke control modes in the subway station. Distribution of smoke and heat due to fire on the platform is analyzed by using Fire Dynamics Simulator(FDS V 4.06) of NIST. Various smoke-control ventilation modes and locations of fire are considered. Evacuation and movement of passengers within the platform is simulated by building EXODUS V.4.0.
