Yearly, it seems the fact that the numbers of tunnels with wide sections are on the rise as the length of tunnel and number of lanes continues increasing. According to these trends, well-schemed plans of design, construction and management related with tunnel safety has become to be crucial. It is a high possibility to be observed by the fact that the direct effects of casualties and property damages are caused by the situations of car collisions, bump to solid structures by careless driving and the outbreak on vehicles by mechanical fault. Therefore, in order to prevent these types of accidents, we would make issues md adopt appropriate mechanical and management plans of emergency exits and disaster prevention equipments inside of tunnel, based on up-to dated experiences and study of foreign cases, to structural design technology. The objectives of this study are to recognize related actual problems and suggest improvement plans.

Full embroidery industrial accidents in recent years has shown a declining trend. But disaster embroidery of domestic construction industry were more than 20,000 deaths per year is about 500 people. The government has introduced a construction site often changing the recruitment of new construction based on health and safety as an alternative to road safety education training yisuje of construction workers, daily work periods short. Certificate of Basic OSH Training in Constructions had also been evaluated as successful by reducing the accident rate problem. It is conducted in private educational institutions has occurred on the friction between workers and employers and training costs are difficult to approach workers in the education standards for such facilities due to the superintendent. Educational institutions are institutions that have been caused by excessive competition lowered levels of education. There is also a lack of evaluation that the training is limited to the basic safety knowledge. These details are brought formal safety education purposes only and is introducing the results of other self jyeotgi difficult to reap the proceeds to good effect. In this study, we propose a plan for improving operational problems and enemy status based on research data presented after the Certificate of Basic OSH Training in Construction.

The mortality and morbidity caused by injury and poisoning has been major public health problem in Korea. This study was carried out to get information indispensable in developing prevention srategies peculiar to korean rural area. In this study 1.499 people of 496 households. who are living in five rural villages of Chooncheon City. Kang-Won Province. were interviewed in accordance with structured questionaire in 1996. The results obtained are summarized as follows: 1. The age-standardized annual incidence rates of injury and poisoning per 100 persons surveyed were 4.2 in males and 1.9 in females. The difference between sex was statistically significant. 2. The places where most of injuries and poisonings occurred were road 66.7% among males. road 31.6% among females. 3. The occurrence of the injuries and poisonings were clustered in intensive farming season in both males and females. 4. The laceration and stab wound were the most frequent nature of injuries in males and the fracture was the most frequent nature of injuries in females. The fracture. sprain were more frequent among males but sprain and contusion were more frequent among females. 5. Incidence rates of injuries and poisoning by cause were higher in traffic accidents among males. though falls among females. The cause specific incidence rate by age was high in traffic accident for 30-59 year age group. and for the aged people older than 60 years. 6. In the management pattern, 78.8% of the injuries and poisoning were received medical care in hospitals and clinics, and the duration of the treatment over 4 weeks in 37.0%. The results obtained indicate that organized community effort is urgently required to prevent injuries and poisonings in rural area.

Objectives: The aim of this study was to model the avoidable burden of the risk factors of road traffic crashes in Iran and to prioritize interventions to reduce that burden. Methods: The prevalence and the effect size of the risk factors were obtained from data documented by the traffic police of Iran in 2013. The effect size was estimated using an ordinal regression model. The potential impact fraction index was applied to calculate the avoidable burden in order to prioritize interventions. This index was calculated for theoretical, plausible, and feasible minimum risk level scenarios. The joint effects of the risk factors were then estimated for all the scenarios. Results: The highest avoidable burdens in the theoretical, plausible, and feasible minimum risk level scenarios for the non-use of child restraints on urban roads were 52.25, 28.63, and 46.67, respectively. In contrast, the value of this index for speeding was 76.24, 37.00, and 62.23, respectively, for rural roads. Conclusions: On the basis of the different scenarios considered in this research, we suggest focusing on future interventions to decrease the prevalence of speeding, the non-use of child restraints, the use of cell phones while driving, and helmet disuse, and the laws related to these items should be considered seriously.

Recently, there has been active research on smart street lamps that can collect real-time traffic data and provide traffic information by attaching images and radars to road lighting facilities. Smart street light technology can detect, identify, and provide dense information compared to existing technologies. In order to effectively utilize the smart streetlight as a high-resolution information delivery medium, a branch-type operation strategy that is different from the existing centralized operation strategy is required. This study presents dynamic information delivery strategies, release strategies, and their criteria for various purposes in a spatial range, separated by the context before and after the occurrence of smart street lights-based accidents. Through this, it is expected that smart road lighting facilities can be used more effectively.

Regular or irregular situations such as traffic accidents, damage to road facilities, maintenance or repair work, and vehicle breakdowns occur frequently on highways. It is required to provide traffic services to drivers by promptly recognizing these regular or irregular situations, various techniques have been developed for rapidly collecting data and detecting abnormal traffic conditions to solve the problem. We propose a method that can be used for verification and demonstration of unexpected situation algorithms by establishing a system and developing algorithms for detecting unexpected situations on highways. For the detection of emergencies on expressways, a system was established by defining the expressway contingency and algorithm development, and a test bed was operated to suggest a method that can be used for verification and demonstration of contingency algorithms. In this study, a system was established by defining the unexpected situation and developing an algorithm to detect the unexpected situation on the highway, and a method that can be used verifying and demonstrating unexpected situations. It is expected to secure golden time for the injured by reducing the effectiveness of secondary accidents. Also predictable accidents can be reduced in case of unexpected situations and the detection time of unpredictable accidents.

After the death of Min-sik Kim in Asan, South Chungcheong Province in September 2019, awareness of the school zone has been increasing, and the traffic law is being revised continuously. However, despite these efforts, the number of traffic accidents among children has not decreased significantly. This indicates the need for a new direction considering the behavioral characteristics of children and the traffic environment. Therefore, this study identified the current status and problems of school zones through case analysis of school zones in Korea. In addition, we analyzed the Vision Zero policy, the concept of Home Zone, and engineering-oriented road design cases and operation methods in Sweden, an advanced country in traffic safety. In addition, the cases of the two countries were compared and organized focusing on the basic principles of disaster prevention design. The purpose of this study is to suggest the direction of design and policy to improve school zone problems in Korea. Through this, it is expected that the results of this study will be used as data for future research development for the reduction of school zone fatalities in Korea.

Traffic accidents can be defined as a physical collision event of vehicles occurred instantaneously when drivers do not perceive the surrounding vehicles and roadway environments properly. Therefore, detecting the high potential events that cause traffic accidents with monitoring the interactions among the surroundings continuously by driver is the prerequisite for prevention the traffic accidents. For the analysis, basic data were collected to analyze interactions using a test vehicle which is equipped the GPS(Global Positioning System)-IMU(Inertial Measurement Unit), camera, radar and RiDAR. From the collected data, highway geometric information and the surrounding traffic situation were analyzed and then safety evaluation algorithm for driving vehicle was developed. In order to detect a dangerous event of interaction with surrounding vehicles, locations and speed data of surrounding vehicles acquired from the radar sensor were used. Using the collected data, the tangent and curve section were divided and the driving safety evaluation algorithm which is considered the highway geometric characteristic were developed. This study also proposed an algorithm that can assess the possibility of collision against surrounding vehicles considering the characteristics of geometric road structure. The methodology proposed in this study is expected to be utilized in the fields of autonomous vehicles in the future since this methodology can assess the driving safety using collectible data from vehicle's sensors.

Although the accident rate is lower than the road tunnel, fire in railway tunnel can bring large damage of human life. In the high speed railway tunnel, the possibility of the railway-disaster (fire) is growing in consideration of the speedy railway and the tunnel length. For that reason, MLTM (Ministry of Land, Transport and Maritime Affairs) published "Rules about the Safety Standard of Railroad (2005.10.27)" and "The Detailed Safety Standard of Railroad (2006.9.22)". According to those, QRA(Quantitative Risk Analysis) technique is recommended to be applied to railway tunnel design which is longer than 1km for assuring the safety function and estimating the risk. However, it is difficult to perform the disaster prevention design due to lack of the detailed standards about event scenario, fire intensity, incidence rate of accidents etc. Therefore, This paper introduces the case of tunnel design for disaster prevention of the Honam high speed railway including the detailed standards of QRA and reasonable safety facilities.
