  • This study propose a model for railway safety evaluation with which the safety of whole railway system can be evaluated. The evaluation model is to generate a safety index which quantitatively represent the degree of railway safety. Safety index is proposed a function of three indexes; an accident index, safety management index, and safety culture index. This paper describes the first result from the study on the safety target which will be a key starting point toward the development of safety evaluation model. It is recommended that the safety target be composed of several sub-targets that are apportioned to constituent components. It is concluded that the classification of safety target influence on deciding components or attributes that constitute each sub-indexes; an accident index, safety management index, and safety culture index. Based on this study, a railway safety evaluation model will be developed in the next study.

  • 국가에서는 철도운영 및 시설기관에 산재되어 있는 철도안전정보를 수집하여 분석할 수 있는 철도안전정보 종합관리시스템을 구축하야 철도안전관리를 효율적으로 수행하기 위하여 노력하고 있다. 매년 철도안전도를 평가하기 위하여 철도사고 자료를 분석하여 사망자 및 부상자 수를 산출하고 있으며 사고 원인 및 위험발생 경위를 규명하여 사고를 최소화 할 수 있도록 여러 안잔정책 및 안전관리방안을 시행하고 있다. 따라서 보다 선진적인 안전정책 수립 및 안전관리를 위해 철도안전도를 입체적으로 그리고 정량적으로 표현할 수 있는 방안이 필요하며 이를 위해서는 안전에 대한 주요 영향요소가 무엇인지를 파악해야 하며 선정된 개발적 요소들에 대한 정량적 철도안전지수(Railway Safety Index)를 개발해야 한다. 본 연구에서는 철도안전도를 정량적으로 평가할 수 있는 안전도 평가지표를 개발하여 안전목표 수립 및 관리 등 철도안전향상를 위한 전략적 방향 및 정책수립 과정에서 활용할 수 있는 모델을 제공하고자 한다.

  • Traffic Accident Merging Index (TAMI) is developed for TMACS (Traffic Safety Information Management Complex System). TAMI is calculated by combining 'Severity Index' and 'Frequency'. The existing indexes are Traffic deaths per 100,000 population, Traffic deaths per 100,000 inhabitants/per billion veh-km, etc. However, there is no consistency in using them among local governments, so it can create confusion. Moreover, the index level is too complicated to understand. Therefore, this study suggests new traffic safety index, TAMI. It will work to improve the weaknesses and present accurate status of traffic safety in local governments.

  • Traffic Accident Merging Index(TAMI) is developed for TMACS(Traffic Safety Information Management Complex System). TAMI is calculated by combining 'Severity Index' and 'Frequency'. This paper suggest the accurate TAMI prediction model by time series forecasting. Preventing the traffic accident by accurately predicting it in advance can greatly improve road traffic safety. Searches the model which minimizes the error of 230 local self-governing groups. TAMI of 2007~2009 years data predicts TAMI of 2010. And TAMI of 2010 compares an actual index and a prediction index. And the error is minimized the constant where selects. Exponential Smoothing model was selected. And smoothing constant was decided with 0.59. TAMI Forecasting model provides traffic next year safety information of the local government.

  • 본 논문은 생활안전지수 보정 방안에 대한 연구를 소개한다. 생활안전지수는 생활안전 예방서비스 시스템에서 제공되는 서비스로써, 개인의 일상생활 안전수준을 종합적으로 평가하여 개개인의 안전상태를 수시로 파악하고, 안전사고를 사전에 예방하기 위해 종합지수 형태로 나타낸다. 이전의 선행 연구에서는 생활안전 예방서비스를 평가하기 위한 평가 기준(항목)을 기반으로 하여 AHP(Analysis Hierarchy Process)와 Likert Scale 기법을 혼용하여 개발되었다. 이에 본 연구에서는 이러한 기존의 생활안전지수를 기반으로, 개인의 특성에 따른 보정 인자를 생활안전지수에 적용하는 방안을 탐구하고자 한다. 기존의 국가 통계를 활용한 보정 인자를 개발하여 개인 프로파일에 맞는 개별화된 서비스를 제공하는 방법을 제시한다. 따라서 본 논문은 생활안전지수 개발 및 보정 방법론에 대한 응용을 통해 사용자 맞춤형 서비스를 제공하는 방법에 대하여 제안하고자 한다.

  • In order to establish railway long-tenn safety policy, various railway safety indexes are required. But these indexes are not use efficiently due to the limitation of safety information. Recently m any safety related information have been obtained based on Railway Safety Act 2004. In this study, various safety index, which can be applied both preventive safety activities and safety measure development, are proposed. These safety indexes are based on common safety index in European Railway Agency, but also include special index in Korea. Proposed safety index include accident results, precursors to accident, infrastructure, accident cost and safety management system. These indexes will be applied in railway industry from 2009.

  • This paper examines the effects on safety index analysis with Level II Second-Moment Method. The general two variable problem is examined by means of Cornell safety index ${\beta}c$ Rosenblueth-Esteva safety index ${\beta}_{RE}$ Rackwitz-Fiessler safety index by iterative method and Practical FOSM safety index ${\beta}_p$, which based partly on the concepts given by Paloheimo and Hannus, proposed the algorithm in this paper. The calculated examples have shown that safety index by Practical FOSM Method proposed in this paper would be similar to those in the method by Rosenblueth-Esteva or Rackwitz-Fissler and be simpler in calculation than the Rackwitz's Advanced FOSM Method, in which the iterative procedure has to be used.

  • As natural disasters are increasing due to the unusual weather and the modern society is getting complicated, the rapid change of the urban environment has increased human disasters. Thus, citizens are becoming more anxious about social safety. The importance of preparation for safety has been suggested by providing the disaster safety services such as regional safety index, life safety map, and disaster safety portal application. In this paper, we propose an application framework to predict the urban safety index based on user's location with realtime weather/atmosphere data after creating a predication model based on the machine learning using number of occurrence cases and weather/atmosphere history data. Also, we implement an application to provide traffic safety index with executing preprocessing occurrence cases of traffic and weather/atmosphere data. The existing regional safety index, which is displayed on the Si-gun-gu area, has been mainly utilized to establish safety plans for districts vulnerable to national policies on safety. The proposed system has an advantage to service useful information to citizens by providing urban safety index based on location of interests and current position with realtime related data.

  • Many railway safety measures reduce railway fatalities into half for last 10 years. But more improvement in railway safety is required to meet the social need after railway fire accident in Daegue. Reasonable railway safety index is needed to find out the weak point and efficiencies of various safety measures. But we still have only 2 kinds of safety index which are set for 10 years ago. In order to derive guideline for setting up safety index, we analyze accident cause, previous studies for railway safety improvement in Korea, and other countries safety plan. As a result some proposal for safety index was driven in this study.

  • A disaster can be defined in many ways based on perspectives, in addition, its types are able to classify differently by various standards. Considering the different perspectives, the disaster can be occurred by natural phenomenon that is like typhoon, earthquake, flood, and drought, and by the accident that is like collapse of facilities, traffic accidents, and environmental pollution, etc. Into the modern society, moreover, the disaster includes the damages by diffusion of epidemic and infectious disease in domestic animals. The disaster was defined by natural and man-made hazards in the past. As societies grew with changes of paradigm, social factors have been included in the concept of the disaster according to new types unexpected by new disease and scientific technology. Change the concept of social disasters, Ministry of Public Safety and Security (MPSS) has provided the regional safety index, which measures the safety level of a local government. However, this regional safety index has some limitation to use because this index provides the information for city unit which is a unit of administrative districts of urban. Since these administrative districts units are on a different level with urban and rural areas, the regional safety index provided by MPSS is not be able to direct apply to the rural areas. The purpose of this study is to determine the regional safety index targeting rural areas. To estimate the safety index, we was used for 3 indicators of the MPSS, a fire, a crime, and an infectious disease which are evaluable the regional safety index using an accessibility analysis. For determining the regional safety index using accessibility from community centers to public facilities, the safety index of fire, crime, and infectious disease used access time to fire station, police office, and medical facility, respectively. An integrated Cheongju, targeting areas in this study, is mixed region with urban and rural areas. The results of regional safety index about urban and rural areas, the safety index in rural area is relatively higher than in the urban. Neverthless the investment would be needed to improve the safety in the rural areas.
