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.

In order to present basic data for the balancing improvement of safety management level in domestic construction companies the improvement index and characteristic of safety management level are offered by comparing the year 2006's safety level with the year 2001's one. The companies under concern are classified into 51 large scale companies and 61 middle and small scale ones. The safety management level of both head office and construction sites is improved for all companies without regard to the scale. Specially, the improvement index of middle and small scale companies shows the higher rate than large ones and head office higher than construction sites.

In the chemical process industries, accidents have a high potential and large effects on catastrophic results. Therefore the safety management for accident prevention plays a crucial role to guarantee the process safety. For these reasons, many systematic methods for safety management system have been widely employed in the fields of chemical processes. PSM (Process safety management) is one of most representative methods. The audit system, which is one of PSM system components, evaluates the performance of PMS system. However, most existing safety audit systems are not systematic and these are performed based on knowledges and experiences of various specialist. Moreover, the safety audit is only performed based on each independent technical component. So, the results of safety audit are not a quantitative index but only a series of commentaries. Finally, it is very difficult to obtain the comparison with other plants or industries. In this study, the novel systematic method and index-based accident database of auditing safety management systems for quantitative assessment are proposed. First, the elements of safety audit replace technical methods to categories of accident database. The F-N curve of each category for accident database is employed to derive the index for quantitative assessment. The Accidental Factor Risk Index (AFRI) is suggested for evaluating the effect of each element in accident database and safety audit system. The safety audit can be modified according to the proposed index.

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.

본 연구는 '해운선사 안전관리 평가지표 개발에 관한 연구'의 후속연구로서 선행연구에서 도출한 '안전관리 평가지표'의 '안전가점' 지수에 해당하는 안전경영 지표의 평가항목을 개발하고, 적정성을 평가하는데 목적이 있다. 이를 위해 해상화물운송사업장에서 일하는 안전관리 담당자를 대상으로 의견을 수렴하여 안전경영 지표별 11개의 평가항목을 개발하였다. 식별된 11개 평가항목에 대한 적정성 검토를 위해 설문조사를 실시하고, 사업형태별(내항해상화물운송, 외항해상화물운송), 사업규모별(보유선박수)로 응답자의 적정성 인식의 차이를 통계적 기법을 활용하여 분석하였다. 그 결과, 평가항목에 대한 적정성 인식의 차이는 사업형태와는 무관하였다. 그러나 사업규모에 따라서는 소(小) 중(中) 대(大) 3개의 그룹 간 평가항목의 적정성에 인식의 차이가 존재했다. 따라서 향후 안전경영 지표를 활용하여 선사를 평가할 경우, 사업형태별로 동일하게 평가하되 사업규모별로는 보유선박수에 따라 그룹화하여 평가하는 것이 타당하다는 결론을 얻었다.

Domestic industrial accidents continue to increase, with 2,142 deaths in 2018, up by 185 (9.5%) from 1,957 deaths in 2017. Industrial accidents that cause loss of human lives pose a serious risk to businesses because of the strengthening of safety regulations and the changing public perception of social responsibility. Accordingly, to prevent industrial accidents, companies regularly conduct onsite safety activities and conduct education and training to raise awareness among employees. However, many such corporate activities are not conducted voluntarily and practically by employees but mostly by formal implementation. To discontinue this customary and passive behavior of employees and establish a mature safety culture, strengthening the execution power of safety management at the site is of paramount importance, and to this end, we aim to utilize the safety practice index (SPI). In this study, the SPI calculated on the basis of the results of the 2018 and 2019 risk management and safety activities of a site was compared with the reported safety accidents. The results confirmed that the SPI index can be used as a valid indicator for safety activities for accident prevention, such as strengthening leadership and safety policies to grade and manage safety management levels for a certain period of time or by a department or to convert weaknesses into strengths.

A performance measurement system for safety management was suggested with which performance of a company's safety activities can be expressed rationally, and analysis of impact with performance improvement. A key of the measurement system is performance index of the safety management activities, which consists of 3 perspectives; an external perspective, an internal perspective, and a innovation & learning perspective. Every perspective consists of 18 performance indices and each indices consist of activity unit a such planning, support, implementation, evaluation and review.

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.

In this study, a GIS-based park safety assessment index was developed to enable objective park vulnerability assessment through data-based GIS analysis, a safety assessment was conducted by selecting a target site where various parks are operated and applying the park safety assessment index. In addition, a facility management system was developed for efficient management of the park safety assessment to update the park safety and provide a foothold for indirect PPGIS. In the case of the assessment index of the safety rating of the park, it was possible to conclude that the accurate quantitative performance was given to the calculation of the safety grade of the park based on the fact that the facilities are different depending on the environment and the size of the park. In addition, the marking the safety grade of parks, as well as the function to show the safety facilities of parks, a common living area for citizens, the management system is expected to have an impact on promoting the use of parks. In the future, in functions such as reporting of facility failures and verifying civil information are implemented by applying civic group participation programs and crowd-sourcing technologies, it is believed that all facilities as well as parks managed by the local government can be managed more efficiently.

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.
