  • This study deal with the traffic accident. The purpose of this study is to develop the accident density models reflecting the transportation and socioeconomic characteristics based on 230 zones of Korea. In this study, The models which are tested to be statistically significant are developed through multiple linear regression analysis. The main research results are as follows. First, in the transportation-based model, road length, avenue ratio, number of intersections and tunnels are analyzed to be positive to the model, however, school zone is analyzed to be negative to the model. Second, in the socioeconomic-based model, population density, transportation vulnerable ratio, children and truck ratio are analyzed to be positive to the model. Finally, in the integrated models, road ratio, population density, transportation vulnerable ratio, children ratio, truck ratio and number of companies are analyzed to be positive, however, school zone is analyzed to be negative to the model. This results could be expected to give good implications to accident-reduction policy-making.

  • Logistics cost of domestic company has been improved continuously and annually, it is still higher than other main comparative countries. So, in this study, as optimizing the logistic network of distribution, it was trying to find methods decreasing logistics cost and storage cost, which occupies 86% of logistics cost of companies. through the efficiency of transportation and delivery routing, it could be also possible to decrease the logistics cost. And, it is also checked to find the logistics cost could be decreased by 10% by optimizing the routes of transportation and delivery, improving the transportation mode, etc.

  • Regulation for the testing and operation of autonomous vehicles on public roadways has been recently developed all over the world. For example, the licensing standards and the evaluation technology for autonomous vehicles have been proposed in California, Nevada and EU. But specific safety evaluation scenarios for autonomous vehicles have not been proposed yet. This paper presents safety evaluation scenarios for extraordinary service permission of autonomous vehicles on highways. A total of five scenarios are selected in consideration of safety priority and real traffic situation. These scenarios are developed based on existing ADAS evaluation and simulation of autonomous vehicle algorithm. Also, Safety evaluation factors are developed based on ISO requirements, other papers and the current traffic regulations. These scenarios are investigated via computer simulation.

  • While the vessel become bigger and high speed, navigational passages become narrow due to an enlargement of all sorts of new ports, sea-crossing bridges and anchorages, leading to the high probability of marine accidents. Furthermore, a constant increase in the maritime transportation and the traffic volume on the sea led to a variety of sea traffic environments and it is a trend for the demand for the sea transportation environment to increase steadily. At this point of time, the Ministry of Land, Transport, and Maritime Affairs introduced the Korea Maritime Safety Laws evaluating the degree that The Safety Audit System for maritime transport, which evaluates the degree that all kinds of port facilities installed temporarily or installed into navigational passages, and the installations and repair constructions of S.O.C. facilities affect ships' traffic safety, was introduced through Korea Maritime Safety Laws and went into effect from November 28th, 2009. This study was performed to introduce an outline including the concept and purpose of the Maritime Safety Audit(MSA) system for maritime transport and the technological guidelines for scientific and standardized enforcement, thereby analyzing the system.

  • 유럽 및 미국에서는 안전하며 환경친화적인 연안운송이 활성화되어 있으나 국내의 경우 연안운송에 의한 화물운송은 극히 저조한 실정이다. 본 연구에서는 목포-제주 사이의 해상화물 분석 결과에 기초하여 육상/해상 복합운송시스템을 제안한다. 먼저 목포 및 제주의 반출입 화물 현황을 조사하고 연안항로 및 여객 화물에 대하여 분석한다. 그리고 철도-선박, 트럭-선박의 복합운송과 RORO선 연안운송 등에 대하여 고찰하였다. 마지막으로 목포-제주 항로에 대하여 RORO선을 활용한 연안운송시스템을 제안하고 그 기술적 타당성을 확인하였다.

  • When temporary spent fuel storage pools at nuclear power plants reach their capacity limit, the spent fuel must be moved to an alternative storage facility. However, radioactive materials must be handled and stored carefully to avoid severe consequences to the environment. In this study, the risks of three potential accident scenarios (i.e., maritime transportation, an aircraft crashing into an interim storage facility, and on-site transportation) associated with the spent fuel transportation process were analyzed using a probabilistic approach. For each scenario, the probabilities and the consequences were calculated separately to assess the risks: the probabilities were calculated using existing data and statistical models, and the consequences were calculated using computation models. Risk assessment software was developed to conveniently integrate the three scenarios. The risks were analyzed using the developed software according to the shipment route, building characteristics, and spent fuel handling environment. As a result of the risk analysis with varying accident conditions, transportation and storage strategies with relatively low risk were developed for regulators and licensees. The focus of this study was the risk assessment methodology; however, the applied model and input data have some uncertainties. Further research to reduce these uncertainties will improve the accuracy of this model.

  • Cooperative-Intelligent Transport System(C-ITS)는 차량 대 차량 및 차량 대 인프라 무선 통신을 기반으로 교통사고예방을 목적으로 운전자에게 전방위험상황에 대한 정보를 제공한다. 또한 C-ITS 인프라에서 수집되는 차량의 주행행태 정보는 사고발생 개연성 분석을 통해 실시간 도로교통안전성 평가에 활용될 수 있다. 본 연구에서는 차량의 주행정보를 이용하여 도로의 교통안전성을 평가할 수 있는 방법론을 제시하였으며, 시뮬레이션 분석을 통해 방법론의 활용성을 검증하였다. 교통안전대체지표인 Jerk와 Stopping Distance Index(SDI)를 이용하여 개별차량의 주행 위험성을 분석하였으며, 위험성 분석결과를 집계하여 도로 구간별 안전성을 계량화하는 방법을 제시하였다. Jerk 기반의 안전성 평가 결과, 5% 이상의 차량 정보 샘플이 확보되면 본 연구의 방법론이 도로 구간의 교통안전성 평가에 적용 가능한 것으로 분석되었다. 한편, SDI의 경우에는 20% 이상의 샘플이 요구됨을 확인하였다. 이러한 결과는 일정 수준 이상의 사업용차량 센서 자료로 수집된 Jerk와 SDI가 도로 구간의 안전성을 대표할 수 있음을 의미한다. 본 연구의 결과물은 도로의 교통안전성을 실시간으로 평가하고 모니터링하는 시스템 개발의 핵심요소로 활용될 것으로 기대된다.
