  • The automotive industry is developing day by day. Among them, it is very important to prevent accidents while driving. However, despite the importance of developing automobile industry technology, accidents due to road defects increase every year, especially in the rainy season. To this end, we proposed a road defect detection system for road management by converging deep learning and raspberry pi, which show various possibilities. In this paper, we developed a system that visually displays through a map after analyzing the images captured by the Raspberry Pi and the route GPS. The deep learning model trained for this system achieved 96% accuracy. Through this system, it is expected to manage road defects efficiently at a low cost.

  • Based on the survey analysis of safety accidents at construction sites that occur every year, most of them are caused by temporary structures. While analyzing in detail, it is confirmed that the main factors for such accidents are the quality problem of temporary equipment, unstable construction, and arbitrary change. As temporary structure is installed only for the construction of main structure, the reality is that no attention is paid to the construction of temporary structures.

  • Construction accidents result from a combination of factors, including both the actions of workers and the safety conditions on site. Despite advancements in enhancing construction site safety, there remains a gap in comprehending the cognitive processes underlying workers' unsafe behavior. This paper investigates and validates a qualitative model that delves into the potential causes of workers' unsafe actions by examining their cognitive processes, employing a system dynamics approach. By analyzing the interplay of various loops within this model, it offers both short- and long-term safety strategies for managers intent on minimizing unsafe behavior among workers. Specifically, safety managers should prioritize increasing workers' awareness of hazards through education and fostering a positive safety mindset. Moreover, they should task frontline supervisors with directly addressing and rectifying instances of unsafe behavior by workers. Lastly, construction safety managers ought to formulate safety strategies that take into account the cognitive states of workers to mitigate any adverse consequences of biased safety management. The outcomes of this research contribute to our comprehension of methods to enhance hazard perception among workers, curtail unsafe actions, and ultimately reduce construction accidents from a cognitive standpoint.

  • The purpose of this research is to propose an effective traffic safety countermeasure to reduce both violations of road traffic acts and accident rates related to the driver's characteristics by measuring them using Q analysis method, a microscopic statistics analysis method. As a result, violators of the road traffic act could be divided into five driving characteristics and causers of traffic accident could be classified into six driving characteristics. By understanding these characteristics, We could establish a proper traffic safety countermeasure for each driving characteristic. The accomplishments of this research are as follows: The first, We could classify the decisive driving characteristics, which cause road traffic acts and traffic accidents, into internal and external causes. The relationship between each driver's characteristic and the occurrence of the road traffic act and traffic accident could be recognized more clearly. We could find the dangerous driver samples who have Accidents proneness. The second, As a result of analyzing the characteristics of these factors, We could sort out and suggest countermeasure for reducing violation of road traffic acts and traffic accidents as a priority countermeasure and complementary countermeasure. Finally, transportation companies most closely related to automobile accidents can judge new personnels on the basis of their driving characteristics before hiring, and also apply this principle to the traffic safety education vigorously.

  • Objectives: This study was conducted to assess the trend of work-related accident rate in the past 10 years (2002~2011) in Gusan district, Ministry of Employment and Labor, Korea. Methods: To analyze the change of work-related accident rate in the past 10 years in Gunsan District, we analyzed the work-related accident and disease by the type of business, business scale and analyzing the victim's age and job period using workplace information management system(PKMS) in the Ministry of Employment and Labor. Results: The average rate of work-related accidents in Gunsan district was 0.96% in the past 10 years and it was a little higher than that of national average 0.75%. The rates of work-related accidents tended to decrease from 1.11% in 2002, to 1.09% in 2006, and to 0.79% in 2011. Mortality (per 10,000) rates also tended to decrease in the years 2002, 2006, and 2011 as 3.07, 2.46, and 1.53. By the type of business, the average rate of work-related accidents in the past 10 years was the highest in agriculture as 1.77%, followed by forestry farming at 1.76%. By the business scale, the average rate of work-related accidents was the highest in the group of under 5 employees as 2.05% and it was the lowest in the group of more than 300 employees as 0.50%. The ratio of work-related accidents in the 30's age group was decreased from 41.7% in 2002 to 25.2% in 2011 and the ratio for the 50's age group was increased from 28.6% in 2002 to 49.5% in 2011. Conclusions: Although the rate of work-related accident was decreased in the past 10 years, the polarization of work-related accidents rated by the business scale and age groups show a significant difference. So it is needed that the planning and implementing of work-related accidents prevention policies.

  • The construction industry has the highest death rate related to safety accidents of any industry. Furthermore, in contrast to other industries, where the death rate related to safety accidents has been steadily declining, both the death toll and the number of accidents in the construction industry have been on the rise. Construction accidents occur when various risks increase in an intertwined way to reach a tipping point; a moment when such factors cannot be tolerated any longer Conventional safety management methods have restrictions in terms of their ability to fully prevent all types of safety accidents. This research considers ways in which USN technology can be applied to safety management on a construction site, and derives a method of applying USN technology for safety management monitoring. The tasks related to safety management on construction sites, as well as the occurrence of accidents, are first analyzed. By analyzing the characteristics of construction accidents, the factors that must be a priority and the factors that can be a lower priority are derived. Finally, the configuration of a monitoring system for safety management on a construction site to which USN technology is applied is presented. It is expected that safety accidents can be prevented from occurring on construction sites by applying this cutting-edge USN technology.

  • This study is a basic study to prepare safety measures for the tram that is being introduced into Korea by reviewing accident analysis and accident compensation system of the tram. Analysis of accident characteristics of the tram was analyzed based on overseas data. Five years after the inauguration of the tram, accidents were halved and stabilized. Deaths accounted for 0.5 % of all casualties, most accidents were minor. Accidents with other mean transportation were high 84.1 %, among them accidents with passenger cars was found to be highest. The frequent points of accidents were analyzed as intersections and tram stop, and measures for pedestrian accidents were found to be important. Those are proposed safety measures through analyzing tram accident characteristics: Monitoring accidents which occur within five years of its inauguration, developing accident database input system, installation of fences for preventing people from jaywalking, operating traffic signal for preventing people from jaywalking through connection of pedestrian signals and tram signals, clamping down on illegal U-turn cars and jaywalking pedestrian, Also, those are proposed accident treatment measures based on general driver receptively and overseas data: property damage liability coverage (PI) of car insurance, comparative negligence when the accident occurs between car and tram.

  • This study examines the characteristics of traffic accidents involving elderly pedestrians by analyzing relevant data vis-à-vis fatal pedestrian accidents and proposes solutions to reduce such accidents. We analyzed 3,853 cases of fatal accidents involving elderly pedestrians and 1,786 cases involving younger pedestrian (these cases reflect accidents that occurred from 2005 to 2008). The results show that accidents involving the elderly occur more frequently in rural areas than urban areas, especially in autumn; this condition applies even in situations where the elderly exhibit compensation behaviors such as walking on safer roads. We found that elderly pedestrians exhibit a defective behavior in crossing roads, especially in complicated road conditions where intersections and turning/reversing vehicles represent a menacing threat. These characteristics could be explained by the degenerated physical/mental ability of the elderly and by psychological factors such as reduced level of self-confidence.

  • According to the recent statistics of Korean National Police which analyze the present status on the rate of the traffic accidents and their effects in Korea, the number of casualties by traffic accidents of 2004 amounted to 6,563, which means that the average number of casualties per 10,000 vehicles is 3.99. The figure of 3.99 is much larger than 1.85 of U.S.A, 1.10 of Japan, 1.14 of U.K., and 1.23 of Germany. The number of registered vehicles of Korea is steeply increasing since 1997 when it reached 10,000,000. Since then, the number of annual increase is estimated at 860,000 except for the year 1998 when the Korean economy was under the control of IMF, and over 14 million vehicles are registered as of the end of the year 2004. With the increase of vehicles, the violations of traffic rules, crimes using vehicles, car thefts, etc have been imposing a lot of serious problems on our society. On this thesis, we are aiming at analyzing some characteristics of traffic accidents reported to the police and suggesting some kinds of the police activities for securing the safety of the transportation.
