The present authors had conducted several researches(parking violation, traffic signal violation, speed violation, drunk-driving) on driving behaviors of the Korean people focused on cultural psychological perspective. This paper was designed to summarize these previous results. Although each research had dealt with different violation behaviors on driving, there were lots of similarities on the basis of violation. The results reveal the following rationale for incurring violation behaviors. First, most people reported that they violated the rule to pursuit short-term benefit. Second, the violators' psychological characteristics are described in terms of self-centered and self-justification. In addition, the respondents have justified their violated behaviors since the outcome is disadvantageous for the drivers. Furthermore, the violators' are found to possess a permissive attitude toward the other violators'. Finally, the implications of these studies were proposed. All of these findings were discussed in relation to the Korean culture.

우리나라에서는 매년 2천여 건 이상의 해양사고가 발생하고 있으며, 정부는 해양사고의 발생 현황 및 원인분석을 통해 사고 저감을 위한 정책을 수립하고 있다. 중앙해양안전심판원에서는 '해양사고심판법'에 따라 해양사고의 원인을 조사하여 이를 재결서의 형태로 공개하고 있다. 이번 연구에서는 재결서의 원인판단 주제어를 기반으로 텍스트 마이닝을 수행하여 사고 종류별 해양사고 위험요인을 식별하였다. 도출된 키워드는 해양사고의 발생 원인과 밀접한 관계가 있는 키워드로 볼 수 있으므로, 해양사고의 원인분석 및 사고 예방대책 수립에 활용될 수 있을 것으로 전망된다.

This study deals with development of Integrated Transportation Analysis System for Large-scale event. Based on case studies, the requirements of the system were defined and the direction of development was established. The large-scale events that require fast and accurate transportation policy were selected. The data warehouse and data mart were developed by integrating the large-scale event data and the traffic data. Business intelligence system was designed and developed users to allow timely decisions.

This study analyzes presentation methods of traffic guide maps to guide drivers easily and correctly to their destinations on complex road networks. The problems of Korea's guidance systems were analyzed and domestic and international road guide maps were compared. This study includes the problems of road number discernment, such as the sizes, colors and marking intervals on the map. The widths and colors of different hierarchical roads were evaluated. The indices, enlarged downtown maps and uncertainty of grade separation on the map were analyzed and the solutions were also provided.

지난 8월 31일부터 9월 2일까지 대전 엑스포 대전무역전시관에서 "깨끗한 환경과 안전한 축산물"이란 주제로 열렸다. 3일간 열린 박람회 기간동안 14만 여명의 관람객을 유치하여 중부권에서 개최한 박람회로 지리적 효과를 충분히 발휘했고 전반적으로 성공적인 박람회라는 평가 했으나 전시시설 및 대중교통 연계, 숙박시설 인프라 부족, 해외 바이어 서비스 부문에서 개선되어야 할 과제로 남게 되었다.

The amount of energy consumed by a transportation system in a city is influenced not just by a transportation system itself but also by city's spatial character. Yet there have been very limited studies on this subject. This study investigates the factors that influence the energy consumption by a transportation system and city's spatial character. The model of an urban area confined within a definite boundary is assumed in order to develop the relationships between the energy consumption and the transportation system. Various assumptions on the character of a city and activities are made. An equation for computation of the energy consumption is derived with such factors as modal split, densities of residents and workers, as well as technological development. Using the equation, sensitivity analyses are performed in order to identify the relationships between energy consumption and influencing factors. It is found that the modal split is the most powerful factor that determines the energy consumption by the transportation system. Yet it is also found that the densities of residents and workers and the technological factors are very important in determining the amount of energy consumption as well.

Failures on network components of a public transportation system can give rise to the severe degradation of entire system functionality. This paper aims at exploring how potential failures can affect the system flows and reliability of subway network systems in Metropolitan Seoul. To evaluate the range of impacts of disruptions, this research employs a probabilistic approach, network reliability. Network reliability measures the network resiliency and probability of flow loss under a variety of simulated disruptions of critical network components, transfer stations in subway system. By identifying the best and worst scenarios associated with geographical impact, as well as evaluating the criticality of transfer stations, this research presents some insights for protecting current subways systems.

The Traffic controller currently used in Korea is a switch control system that directly transfers 220V of high voltage to traffic lights one to one. This method requires a lot of cables, and there are concerns about electric shock. Accordingly, Korea Road Traffic Authority added the digital communication signal controller standard using digital communication method to the standard specification of the communication signal controller of the National Police Agency. Based on these specifications, this paper intended to develop digital communication call controllers. In addition, it was verified that even if the digital communication signal controller and analogue communication call controller were mixed, they could operate in the signal control system currently in operation.
