In previous research, we analyzed traffic accident characteristics in the Chungcheong region through factor analysis, cluster analysis, and a questionnaire using traffic accident analysis system data to enhance Korea's traffic safety. Based on the analysis results, we investigated the design and application of traffic safety technology in non-urban areas in this study. Three technologies are proposed to improve traffic safety facilities for the region: a recognition light at pedestrian crossing works, a recognition light on the road for the underprivileged in traffic works, and a safety LED sign for operation of agricultural machine works. Each technology complements the light pollution problem about snow removal and road safety when applied to existing facilities in the non-urban areas. Solar-based indigenous technology is expected to contribute to road safety in rural areas.

The adoption of hydrogen-powered Elec is expanding globally. Hydrogen is recognized as a potentially hazardous energy source, and safety assessment is crucial for the development of plans to supply hydrogen-powered electric buses. Hydrogen gas leakage can have a significant impact during bus operations, and continuous hydrogen leakage in hydrogen-powered vehicles can result in fatal accidents. In this study, information about hydrogen leakage is collected through sensors installed within the vehicles and is measured when the sensor detects a leak. The study also proposes the use of Pseudo Fuel Leakage (PFL, %) as an additional indicator for evaluating and monitoring hydrogen safety and leakage.

The purpose of this study was two-fold; first, to develop safety performance functions (SPF) using transportation-related big data for all types of roads in Korea were developed, Second, to provide basic information to develop measures for relatively dangerous roads by evaluating the safety grade for various roads based on it. The coordinates of traffic accident data are used to match roads across the country based on the national standard node and link system. As independent variables, this study effort uses link length, the number of traffic volume data from ViewT established by the Korea Transport Research Institute, and the number of dangerous driving behaviors based on the digital tachograph system installed on commercial vehicles. Based on the methodology and result of analysis used in this study, it is expected that the transportation safety improvement projects can be properly selected, and the effects can be clearly monitored and quantified.

While the number of crashes and fatalities has decreased for the last few decades, the proportion of elderly-involved crashes has continuously increased from 19.5% in 2001 to 29.6% in 2008. This paper aims to evaluate the effectiveness of traffic safety education to seniors, which has been conducted for the purpose of providing more systematic knowledge such as safety regulations and making the elderly more aware of the risks of crashes, and eventually to reduce elderly-involved crashes. First, we investigated the levels of traffic safety knowledge of the elder people who attend senior community centers and social welfare centers in Seoul and provided traffic safety education. Then, the effectiveness of traffic safety education was evaluated by using the before-and-after analysis. We set up two different groups to improve the reliability of evaluation: one for control group and the other for comparison group. The results showed that the average scores of the control group after education were significantly improved at the 95% significance level compared to the average scores before education, whereas the comparison group did not show a significant differences in the average scores before and after education except for two questions. This indicates that the levels of traffic safety knowledge of the control group have been improved through education and therefore, the safety education seem to be effective to some extent.
