The previous studies on analyzing the effects of traffic safety policies are very limited. Implementing traffic safety policies in view of their own urban traffic characteristics would be fairly desirable to handle properly the traffic safety problems. The relationships between traffic accidents and traffic safety policies have been researched by classifying the eighty one cities in Korea into four groups in terms of the size of the city population. Statistical analysis have been conducted for traffic accidents data and traffic safety policies, respectively. In order to mearsure the effectiveness of the traffic policies in the real world, regression models have been developed by handling the accident data and policy data. As a result of analysing the data, the traffic policies have showed different effects according to the size of the cities. While budget investment policies had provided enormous influences to reduce traffic accidents in the big cities more than a half million polulation, traffic enforcement and traffic education have been so efficient to control traffic accident problems in the smaller cities less than a half million poluation.

This article evaluates the effects of eight traffic safety policies such as traffic accident reduction campaign, the seat belt law, three strike out driving while intoxicated, rewarding for reporting traffic offenders on the number of accidents and fatalities. Intervention analysis of time series is used to compare the monthly accident and fatalities with the before and after reinforcement. The results indicate that no significant impact of the traffic enforcement measures on reducing the number of accidents and fatalities.

해양사고는 매년 증가 추세이고 충돌사고 비율은 낮지만, 발생 시 대규모 피해로 있다. 특히, 3톤 미만 소형어선의 경우 바다네비게이션 서비스 등의 지능형해상교통서비스 관련 법규에서 제외되어 해양디지털화 및 해양사고의 사각지대에 놓여있다. 이에 따라, 본 연구에서는 3톤 미만의 소형선박의 환경에서 제공가능하도록 충돌예방에 기여할 수 있는 선박안전 충돌경보 이동형 단말장치 개발을 위하여 시제품을 개발하고, 소형선박 환경에서의 WAVE 기반 통신영역 실증 테스트를 수행함으로써 WAVE 통신기반 단말장치 활용 가능성을 확인하고 개선방안을 도출하였다.

There is a need to provide appropriate transportation safety services to foreigners residing in Korea. The main purpose of this study is to enhance transportation safety services for foreigners. In order to identify the risk of traffic accidents, analysis of traffic accidents was conducted using a survey of foreigner travel behavior. According to the results of this model, the study suggests directions to achieve improvement of traffic safety services for foreigners who are unfamiliar with the transportation systems. The study results show that the risk of traffic accidents is influenced by two factors: comprehension of transport geography and of traffic laws. Necessity of policy is influenced by two factors: comprehension of transportation system and the risk of traffic accidents. Intention of using policy is influenced by two factors: the risk of traffic accidents and necessity of policy. Effect of policy is affected by the intention of using policy. The results also demonstrate that the traffic safety services for foreigner can be described as endogenous variables which are approximately 88% of the traffic safety education, 85% of the demanded multicultural district, and 75% of the portal traffic information. Compared with existing research, this study provides a systematic methodology to evaluate effects and the order of priority in establishing traffic safety policies for foreigners.

An autonomous car(driverless car, self-driving car, robotic car) is a vehicle that is capable of sensing its environment and navigating without human input. Autonomous cars can detect surroundings using a variety of techniques such as radar, lidar, GPS, odometry, and computer vision. Advanced control systems interpret sensory information to identify appropriate navigation paths, as well as obstacles and relevant signage. Autonomous cars have control systems that are capable of analyzing sensory data to distinguish between different cars on the road, which is very useful in planning a path to the desired destination. An issue tree, also called a logic tree, is a graphical breakdown of a question that dissects it into its different components vertically and that progresses into details as it reads to the right.Issue trees are useful in problem solving to identify the root causes of a problem as well as to identify its potential solutions. They also provide a reference point to see how each piece fits into the whole picture of a problem. Using Issue-Tree menthods, transportation safety policies were developed with autonompus vehicle in mind.

교통안전에 대한 지속적인 강화정책에도 불구하고 국내 교통안전수준이 뚜렷한 개선효과를 보이지 못하고 있는 현 시점에서 차량, 도로, 이용자(운전자, 보행자) 간 끊김 없는 정보제공을 가능케 하는 새로운 ITS 융합기술(C-ITS)의 필요성이 어느 때 보다 크다. 본 지에서는 국내 교통사고자료를 바탕으로 국내외에서 검토되고 있는 C-ITS 서비스의 교통안전 기대효과를 살펴보고, 향후 교통안전 혁신을 위한 추가 안전서비스(안)를 제시하고 있다.
