For the commercialization of automated vehicles, it is necessary to create various scenarios that can evaluate driving safety and establish a data system that can verify them. Depending on the vehicle's ODD (Operational Design Domain), there are numerous scenarios with various parameters indicating vehicle driving conditions, but no systematic methodology has been proposed to create and combine scenarios to test them. Therefore, projects are actively underway abroad to establish a scenario library for real-world testing or simulation of autonomous vehicles. However, since it is difficult to obtain data, research is being conducted based on simulations that simulate real road. Therefore, in this study, parameters calculated through individual vehicle trajectory data extracted based on roadside CCTV image-based driving environment DB was proposed through the extracted data. This study can be used as basic data for safety standards for scenarios representing various driving behaviors.

In order to express the luxurious and various colors of cloisonne enamel, it designed with a flower motif. As for the idea development process, it made the flower design by CAD for the development of frame, and substituted the various colors for the developed frame in order to plan the looking after cloisonne frame works, and researched the design processor which can be used variously with the developed frame. After the production of works, it studied about the advantages and disadvantages through the analysis of design and color expression. This research is to develop the luxurious colors of cloisonne enamel and its frame for the popularization of cloisonne enamel craft in order to show the various modern designs in the formal and monotonous design market, and furthermore, it is to be helpful for the popularization of cloisonne enamel, the use of techniques and the modern design industry by the increase of interest in cloisonne enamel.

Before increasing highway design speed, it is necessary to understand the effect of road geometry on safety under super high-speed driving conditions. This will enable roads to be designed to ensure safety. This study uses data collected using a driving simulator that simulates a super high-speed driving environment. Subsequently, the study identifies a safety indicator that can identify the safety with the road geometry and clarify the relationship between road geometry elements and safety indicators using structural equations. The analysis results suggest a specific geometry that reduces safety during high-speed driving. The results of this study are expected to provide basic data for preparing geometric design specifications for increasing design speed.

The rapid aging of drivers and changes in the traffic environment necessitate the improvement of driving education programs. This study aims to suggest improvement plans for driving education programs in Korean safety driving training centers through the analysis of traffic accident characteristics of trainees. The accident data of commercial vehicle drivers that occurred within a year after training was used in this study. The analysis included statistics of the accidents for the drivers and companies with high accident counts. According to the analyzed results, it can be concluded that improvement of training programs for elderly drivers and safe driving awareness is needed. Through domestic and foreign case studies, programs that can identify an individual’s cognitive ability and personalized education program to identify driving characteristics and tendencies were suggested. The training programs presented in this study will contribute to the improvement of driver awareness and the prevention of traffic accidents.

Each ADS must have a validation and evaluation scenario for ODD. This requires a large number of scenarios, so a scenario library must be developed. In order to effectively utilize the scenario library, a system that supports testing in the ODD of the user's choice is required. In other words, in order to develop a scenario library, it is necessary to build a database on actual driving road conditions (geometry, etc.). Accordingly, in this study, we establish a domestic driving environment database based on HD-Map for driving safety testing, design a system that can search test target sections in connection with the ODD of the scenario, and present the implementation results. In the future, it is expected that the domestic driving environment database will be able to create scenarios through linking with the scenario library and directly utilize them for scenario-based evaluation of various demand sources.

Established in 2009, Safe Driving Training Programs Center has been associated with raising awareness regarding the importance of safe driving and has contributed to the reduction of traffic accidents through experience education that is focused on field practice. However, no new experience education courses have been developed since the development of “control the test vehicle training course” in 2013. Therefore, education satisfaction level of the students is continuously decreasing. This study thereby suggested ways to improve experience education program of the Safe Driving Training Programs Center, currently operating in Sangju and Hwaseong. Problems were identified by analyzing the current status of the Safe Driving Training Programs Center program that is currently in operation. This study suggested measures to improve the programs by benchmarking overseas cases. In addition, program improvement was supplemented by referring to the survey results conducted on students of the Safe Driving Training Program Center.
