  • Regarding the characteristics of fatal electric shock accident during the past 10 years, fatalities occurred more frequently in July & August, and AM 10-12 PM & 14-16. Also, the electric shock accident is occurred more frequently in the age group from 30 to 40. Especially, the fatal electric shock accident in construction industry covered more than half of total industry. Therefore, it is strongly requested for the protection technology of an electric shock from the low voltage electric path, grounding method and workers. The aim of this study is to propose the policy about the equipment performance standards and/or worker's safety standards to revise the standards for preventing electric shock accidents on safety workings.

  • Many long railway tunnels without emergency evacuation system or ventilation system are under construction or in-use in Korea. In the case of tunnel-fire, many fatalities are occur in current condition. Current safety level is estimated in this study, for the efficient investment on safety. But so many uncertainties in major input parameters make the safety estimation difficult. In this study, probabilistic techniques are applied for the consideration of uncertainties in major input parameters. As results of this study, accident scenarios and survival ratio under tunnel fire accident are determined for various conditions.

  • Mobile scaffold is used as a work platform in construction sites. According to industrial accident data, 10 fatalities occur annually on average due to falling from mobile scaffold in construction sites. To prevent such fatal accidents, safety standards must be improved by analyzing the causes of fatal accidents related to mobile scaffold. Accordingly, we analyzed domestic and international safety standards for mobile scaffold and analyzed the fatalities (117 persons) caused by mobile scaffold accidents in domestic construction sites during 2011-2020 and found that fall, overturn, and collapse accounted for 88% (103 persons), 10.3% (12 persons), and 1.7% (2 persons) of fatalities, respectively. The main causes of fatal accidents were found to be non-installation or insufficient installation of safety rails and outriggers and incorrect sequence of work. Based on the analysis results, we proposed strategies for improving the safety standards, such as the use of advanced guard rails and wheel-attached outriggers, to enhance the safety and field applicability of the mobile scaffold. Technology development and improvements in the safety standards for the use of mobile scaffold will aid in the prevention of fatal accidents caused by mobile scaffold.

  • PURPOSES: The operational characteristics of roundabouts are generally influenced by location as well as traffic volume. The goal of this study is to develop urban and rural roundabout accident models and to discuss safety improvement guidelines based on the model. METHODS : To analyze accidents, count data models are utilized in this study. This study used accident data from 2010 to 2013 for 56 roundabouts collected from the Traffic Accident Analysis System (TASS) of Road Traffic Authority. Poisson and negative binomial regression models were developed for this study using NLOGIT 4.0. RESULTS : The main results are as follows. First, the hypotheses that there are distributional differences in the number of accidents and injuries/fatalities among rural and urban roundabouts were accepted. Second, Poisson and negative binomial regression accident models, which were all statistically significant, were developed. Seven independent variables, which were statistically significant, were adopted. Third, the common variable of models was evaluated to be traffic volume. CONCLUSIONS : This study developed two negative binomial roundabout accident models and suggested some accident reduction strategies. The results are expected to give some implications to the safety improvement of roundabout.

  • Domestic construction industry has seen a negative image in the sense that various accident occurs frequently. Status of construction accidents in the case of domestic workers is reduced. However, if the situation of foreign workers is increasing every year. This study aims to create high-temperature exposure standard table for foreign workers and domestic workers in the analysis through the discomfort index of fatalities and using the WBGT index for reducing fatalities foreign workers to improve the image of the construction industry.

  • 철도여객 안전에 초점을 둔 안전관리활동의 결과로 철도여객 사망자는 크게 감소하여 2009년 이후 선진국 수준의 높은 안전성을 달성하였다. 반면, 철도종사자의 작업중 사고는 지속적으로 발생하여 선진국 사고율의 5배 이상 높은 실정이다. 철도종사자의 작업중 사고율이 높으나, 이에 대한 기초연구가 부족하고 사고 원인 중 상당수가 작업자 개인의 부주의로 보고되고 있어 현재까지 종합적인 종사자의 사고예방을 위한 안전대책이 없는 실정이다. 본 연구에서는 국내 철도사고통계를 분석하여 종사자의 작업중 사고원인을 분석하였다. 종사자의 작업중 사고중 피해가 가장 큰 운행중인 열차와 작업자의 충돌로 인한 철도교통사고에 초점을 두었으며, 사고 피해예방 대책 현황 및 국내의 문제점 분석, 국내외 안전성 비교 등을 수행하여, 종사자의 직무사고 예방을 위한 새로운 대책 개발에 활용하고자 하였다.

  • Korea have 3 kinds of national railway safety target, which are accident fatalities, train accident rate, and passenger fatality per passenger kilometer. Increase of railway passenger and train operator force to setting up new safety target. Current safety target can not reflect train operator's safety activities because it include suicide and trespass related accident, which are hard to control by the operators. In order to reflect to the 2nd National Integrated Railway Safety Plan, new safety targets are roposed in this study.

  • This article proposes a method to assess construction safety risk during the construction phase based on accident loss costs. Risk assessments for hazardous construction work are required by law, but they lack quantitative criteria. To address this, a survey estimated loss costs due to fatalities in the construction industry, finding labor loss cost and delay reimbursement cost to be the largest factors. The proposed method uses algorithm to calculate expected accidents and risk levels based on project characteristics, work methods, personnel, and environment data. This method is expected to enhance the reliability and usability of risk assessments during the construction phase of construction projects.

  • 2010년 서울의 교통사고 사망자는 424명이며, 이들 중 227명(54%)이 보행자 사고이다. 또한 보행자 사망사고 중 보행자 사망사고의 40%가 무단횡단에 의한 사고로 나타났다. 따라서 본 연구에서는 보행자 사고에서 큰 비중을 차지하는 무단횡단을 예방하는 방법을 제안하며 문헌 고찰, 인적 요인 및 차량 특성, 사고지점의 기하학적 특성을 반영하여 연구를 수행하였다. 방법 제시에 앞서 사고 요인을 밝히기 위해 무단횡단 사고의 실험 및 통계 분석을 수행하였다. 첫째, 인적요인 분석을 통해 고속으로 주행하는 운전자가 무단횡단 사망사고에 큰 비중을 차지하고 있는 것으로 나타났다. 둘째, 보행자 측면에서는 고령자들이 무단횡단 사망사고에 취약했으며 버스나 택시와의 사고에서 사고 심각도가 높았다. 마지막으로 도로 및 환경 측면에서 차로수와 노면상태에 관련하여 분석했을 때, 일반적인 예상과 다른 결과를 보이기도 했다. 본 연구는 보행자 사망사고를 예방하는 방법을 증진시키고, 보행자 안전에 대한 논의에 이용될 수 있을 것이다.

  • This paper addresses a GIS (Geographic Information System) based system in order to reduce the rate of public transportation accidents occurring in Iranian roads network. Over the years, the road accidents are a major issue throughout the world. Today, particular consideration is given to those technologies which can lead to diminish on the number of critical incidents. One of the main factors resulting in accidents and fatalities rates growth is the speed violation of buses in Iranian road network. The conventional speed controlling approach in Iran based on the Tachograph which records vehicle's speed, time, and stoppage in the mechanical processing has many problems. Hence, this research is intended to design and implement a GIS-based system to manage road accident of Bus transportation system using offline tracking system. This was accomplished using a GIS-based technique that encompasses three steps. The first step is developing a GIS-based accident system. The second step includes designing and applying a tracking system inside 90 buses for recording Bus information for speed controlling. Lastly, by using mentioned system in police center, the illegal drivers' punishment would be considered properly. Overall, this system has been successfully applied in this work. Therefore, the police and transportation office are able to control and make policy to diminish the number of accident. It is anticipated that online tracking system through the Web GIS would be utilized In this system in the near future.
