  • 국토교통부에 따르면 2014년, 대한민국의 자동차 1대당 인구수가 2.56명으로 기록되었다고 한다. 또한, 교통안전공단에 의하면, 2015년 총 교통사고는 23만 2035건이 발생하였고 이로 인한 사망자는 4621명이라고 한다. 그 중 약 53%인 12만 3760건이 폭이 9m 미만인 이면도로에서 발생하였고 이로 인한 사망자는 전체 사망자의 약 56%인 2586명이라고 한다. 이는 상당히 수의 사고들이 이면도로에서 일어나고 있음을 알려준다. 국민 안전의 측면에서 많은 사고의 위험이 있는 이면도로에 사고를 예방할 수 있는 대책이 시급하다. 이에 본 논문에서 IoT(사물인터넷)을 기반으로 한 이면도로에서의 사고 예방 장치를 제시하여 '차량과 차량'뿐만 아니라 '차량과 보행자', '차량과 자전거' 충돌사고 문제해결에 접목하였다.

  • Necessarily traffic policies have been biased in car than pedestrian, so pedestrian's environment is getting worse. Result of this situation our accident rate is high as 36.4%, compared to OECD member countries with average rate of 17.8%(in 2009). Increasing interest for pedestrians environment improvement, and it make an effort to build environment to guarantee walk and safety of pedestrians. Analysis on the binary logistic regression(BLR) was used. The dependent variable is occurring from the road width of less than 9m accident, and independent variable extracted can be obtained from the traffic accident data. Traffic accident on roads having width of less than 9 meters affecting variables is when the driver is straight, when the driver is female, when the pedestrian is walk driveway, and so on. To prevent it, efforts is demanded to protect handicapped, to build safe pedestrians environment using C-ITS and to decrease speed of going straight vehicle on roads having width of less than 9 meters.

  • This study develops a methodology on how to assess the traffic safety benefit of advanced vehicular technology for Protecting pedestrian in pedestrian-vehicle collision. Safety benefit is defined here as the reduction of Pedestrian fatality by employing advanced vehicular technology. As an application of the proposed methodology the safety benefit of active hood lift system (AHLS) is assessed. Both actual accident data analysis and simulation experiment are conducted to establish statistical models that are used for estimating the reduction of pedestrian fatality It is believed that the developed methodology and outcomes would be greatly useful in developing various advanced vehicular technologies and establishing more effective traffic safety policies.

  • This paper try to identify the minimum speed of vehicles in collision between pedestrian head and windshield at vehicle-pedestrian accidents. The MADYMO program was used with NF Sonata vehicle and pedestrian in height of 160cm, 170cm, and 180cm. From the simulation results, it was found that the minimum speed of vehicle was different for each pedestrian height : 49km/h for 160cm, 41km/h for 170cm, and 29km/h for 180cm. The results could be used in speed estimating process when there is a collision trace between pedestrian head and windshield at vehicle- pedestrian accident investigation.

  • 탈거리의 발달은 급기야 전 세계를 하루 생활권으로 만들었다. 비행기, 기차, 자동차, 선박 같은 교통수단의 발달은 이른바 글로벌시대를 열어 전 세계가 하나의 가족이 되어 가는데 가장 큰 역할을 했고, 특히 자동차는 사람이나 화물을 운송하는 주요 수단으로서 현대인들에게 의식주 못지않게 중요한 필수품이 되었으며, 전 세계적으로 그 수요가 급속히 증가하고 있는 실정이다. 자동차는 시간과 공간을 효율적으로 사용할 수 있게 하는 등 많은 이익을 주는 반면 교통사고 및 교통체증에 의한 인적, 물적, 경제적 손실 등과 같은 많은 사회적 문제들을 유발시키고 있는 것도 사실이다. 일반적으로 교통사고는 인간적, 차량적, 도로적 요인 등 개개별 요인과 이들의 교호작용에 의해서 발생하기 때문에 차량의 안전운행을 위한 대책은 이들 요인들의 종합적인 분석을 통하여 해결할 수 있다. 이에 따라 운전자와 보행자를 동시에 보호할 수 있고, 운행 시 운전자의 편의를 제공할 수 있는 차량안전시스템 및 이를 위한 제어기술, 정보통신기술, ITS기술, 차량동역학기술 및 차체설계기술 등이 개발 되고 있고, 과거 자동차에서는 볼 수 없었던 시트벨트, 에어백, 범퍼, 차체충격흡수장치, 도어 임팩트 빔 등이 개발되어 교통사고 시 피해를 극소화하는데 기여하고 있다.

  • This study developed a methodology for estimating the fatality reduction by introducing technical regulation on pedestrian protection in pedestrian-vehicle collisions. Modeling a probabilistic pedestrian fatality model with logistic regression approach was one of keen interests, which employed in estimating the fatality reduction. Collision speed obtained from the accident reconstruction was used in the model development. The effects of fatality reduction, in case various Head Injury Criterion (HIC) and collision speeds are applied for the regulation. were presented as the major outcome of this study. It is expected that the outcome of this study would be an invaluable tool to assist in developing various technologies and policies for pedestrian protection.

  • Pedestrian traffic needs to be accurately quantified to predict effectively pedestrian traffic accidents, however, pedestrian traffic is more difficult to measure than vehicle traffic. In this study, we suggest the time-and cost-effective application of mobile closed-circuit television (CCTV) using a smartphone as an alternative that can collect and analyze real-time data with little. In the present investigation, the pedestrian-vehicle conflict that can develop into an accident was defined as the pedestrian accident exposure. After installing mobile CCTV in 40 sections of Dongseong-ro, Daegu, the pedestrian accident exposure was estimated through negative binomial regression analysis using the collected data. The results of the analysis showed statistically significant changes in the pedestrian accident exposure variables. Based on the present results, a pedestrian accident exposure estimation model was developed which can be used in sections where pedestrian accidents may occur.

  • The purpose of this study is to find out the characteristics of elderly pedestrian accidents and to suggest policy implications to enhance the level of elderly pedestrian safety. Although much efforts has made to enhance traffic safety environment, pedestrian traffic accidents among elderly population are not significantly decreased. This is mainly because current traffic safety measures do not much consider the characteristics of elderly pedestrians in the aspects of physical and psychological conditions. Main findings from vehicle-pedestrian traffic accident data and survey are as follows. First elderly pedestrians have high probability of traffic accident near crosswalks or cross streets rather than on crosswalk or cross streets. Second they need more green light time for crossing the streets. Third, they feel motor cycles running on the side walk and parked vehicles on the side walk are the most dangerous factors. Forth, general drivers do not have reasonable understanding for the walking behaviors of elderly pedestrians. Fifth, elderly pedestrians frequently need to rest while walking. Sixth, elderly people do not see clearly or understand traffic signs. Finally, many elderly pedestrians experience accidents or inconvenience while walking on the sidewalk.

  • As the elderly are increasing, traffic accidents which are related to the elderly are one of major issues in aged society. In this paper, we analyze traffic accident statistics for the elderly. Based on the analyzed data, safety message transmission system for the elderly pedestrians is introduced. The proposed system is based on the P2V(Pedestrian-to-Vehicle) communication which combines ICT(Information and Communication Technology) with vehicles and pedestrians. We introduce the concept and principle of the proposed system and discuss implementation issues for realizing the proposed system.

  • Efforts are being made to prevent traffic accidents in the school zone in advance. However, traffic accidents in school zones continue to occur. If the driver can know the situation information in the child protection area in advance, accidents can be reduced. In this paper, we design a camera that eliminates blind spots in school zones and a number recognition camera system that can collect pre-traffic information. It is designed by improving the LIDAR system that recognizes vehicle speed and pedestrians. It collects and processes pedestrian and vehicle image information recognized by cameras and LIDAR, and applies artificial intelligence time series analysis and artificial intelligence algorithms. The artificial intelligence traffic accident prevention system learned by deep learning proposed in this paper provides a forced push service that delivers school zone information to the driver to the mobile device in the vehicle before entering the school zone. In addition, school zone traffic information is provided as an alarm on the LED signboard.
