This study examined the factors influencing the number of enforcement cases on traffic signal violation. The study collected enforcement data on traffic signal violation by multi-functional unmanned cameras across the Daegu metropolitan area, and analyzed the data to determine correlations among various factors including physical dimensions and engineering characteristics of the roadway as to how they would influence the number of violations. The resulting analysis provided a general model that assesses applicability for multi-functional unmanned cameras, and further shed helpful insights on efficient utilization of such traffic signal enforcement equipments in terms of installation thresholds and location. By identifying violation-prone features and characteristics and subsequent enforcement considerations, this research also supports safety efforts in reducing the number of traffic accidents as well.

93% of road traffic accidents result from drivers' fault and Korea has the largest number of deaths from traffic accidents among the OECD members. For this reason, the country is measuring Traffic Culture Index (TCI) in each city, gun and gu annually to improve traffic safety policies and promote safety consciousness, but the influencing relation between TCI and actual traffic accidents is only based on the assumptions and no verification has been carried out, yet. Therefore, this study aims to verify if in reality, TCI represents the traffic culture level and has an influencing relation with traffic accidents and to suggest an improvement plan of research on the present state of TCI, based on the result. For this purpose, bases on data of the report about the present state of TCI from 2010 to 2012, and the influencing relation between the number of traffic accidents and the number of deaths from traffic accidents was analyzed through structural equation model. For influencing relation analysis through structural equation, research 1 to analyze the relation among TCI in each city, gun and gu, the number of traffic accidents and the number of deaths, and research 2 to analyze the influencing relation of the increase in TCI, the number of traffic accidents and the number of deaths were carried out. When verifying the influencing relation with traffic accidents through structural equation, the goodness of fit of the model was low in research 1 and as TCI increased, the number of accidents and deaths decreased in research 2 and thus the effect of TCI was verified.

This paper proposed an accident prediction model in order to prevent accidents in mountain areas using a big data analysis. Data of accidents in mountain areas are shown as graphs. We have analyzed cases: the number of accidents per year, day of week, time of day to find patterns of the negligent accident in mountain areas. The proposed prediction model consists of weighted variables of the accident in mountain through visualized big data analysis. The model of danger index performance is demonstrated by showing accident-prone areas with weighted variables.

The purpose of this study is to analyze the characteristics of traffic accidents and to develop the models by day and night-time in the case of the arterial link sections. In pursuing the above, this study uses the 224 accident data occurred at the 24 arterial link sections in Cheongju. The main results analyzed are as follows. First, it was analyzed that the number of accidents during day was more than night, but the accidents rate during night was higher than day. Second, four models which were all statistically significant were developed. Finally, the differences between the day and night models were comparatively analyzed using independent variables.

산업의 발달과 함께 대량의 가연성 가스가 가정용 및 산업용 연료로 사용되고 있으며 이 가스 연료의 사용량 증가와 함께 가스와 관련된 사고들이 크게 증가하고 있다. 특히 가연성 가스에 의한 화재 및 폭발사고가 사고건수의 절반정도를 차지하고 있으며 사고 액수로는 약80% 정도를 차지하고 있다. (중략)

In the past 10 years, the accidents caused by drowsy driving have occupied about 23% of all traffic accidents in Korea expressway network and this rate is the highest one among all accident causes. Unlike other types of accidents caused by speeding and distraction to the road, the accidents by drowsy driving should be managed differently because the drowsiness might not be controlled by human's will. To reduce the number of accidents caused by drowsy driving, researchers previously focused on the spot based analysis. However, what we actually need is a segment (link) and occurring time based analysis, rather than spot based analysis. Hence, this research performs initial effort by adapting link concept in terms of drowsy driving on highway. First of all, we analyze the accidents caused by drowsy in historical accident data along with their road environments. Then, links associate with driving time are analyzed using digital tachograph (DTG) data. To carry this out, negative binomial regression models, which are broadly used in the field, including highway safety manual, are used to define the relationship between the number of traffic accidents on expressway and drivers' behavior derived from DTG. From the results, empirical Bayes (EB) and potential for safety improvement (PSI) analysis are performed for potential risk segments of accident caused by drowsy driving on the future. As the result of traffic accidents caused by drowsy driving, the number of the traffic accidents increases with increase in annual average daily traffic (AADT), the proportion of trucks, the amount of DTG data, the average proportion of speeding over 20km/h, the average proportion of deceleration, and the average proportion of sudden lane-changing.

The objective of this study was to estimate the roadkill occurrence of water deer (Hydropotes inermis), a representative roadkill species in South Korea. For this estimation, I analyzed national road statistics and roadkill statistics, and then reviewed case studies that estimated the number of deer roadkill in other countries to apply the estimating methods to our case. As a result, the estimated number of water deer vehicle collision was at least 60,000 per year in South Korea.

In those day, Incheon and Busan local government are arguing about establishment of a maritime court. This study aims to develop a model that evaluates the priority orders for the establishment of maritime courts using maritime casualties counts based on the integrated ELECTRE-CRITIC-ISM technique, as well as to verify its usefulness in the establishment of maritime courts in Korea. For this purpose, a total of 22 ports, excluding nine ports where maritime accident data were integrated and managed among the 31 international trade ports, were matched with the jurisdiction of six alternative high courts. Second, the CRITIC method was used to calculate the weights of the number of maritime casualties during a 5-year period that were evaluation factors and combine with the ELECTRE method. Finally, the ELECTRE&ISM method was used to analyze the concordance and discordance between high courts and evaluate the priority orders considering the fluctuations of maritime casualties counts. As the final evaluation result considering the mean values in fluctuations of maritime casualties counts, the Busan High Court ranked first, the Gwangju high court second, the Seoul high court third, the Daejeon and the Daegu high court forth (equal), and the Suwon high court sith. Therefore, it is necessary to preferentially establish a maritime court in the jurisdiction of the Busan High Court.
