In 2014 Flex-PLIfor the pedestrian protection will be applied to NCAP test. The most significant feature of Flex-PLI is constructed with segmental bone cores for the femur and tibia regions. So it can be more reproducible by representing pedestrian injuries such as knee ligament and tibia injury during the pedestrian crash against vehicle. In this paper, Analyzed the characteristics of Flex-PLI through the structural analysis and the test results by using Flex-PLI for our compact vehicles. Finally countermeasures into compact vehicle were proposed to fulfill the injury criteria of Flex-PLI.

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.

A school zone means a certain section designated among facilities, such as schools, childcare facilities, academies, etc., to protect children from the risk of traffic accidents. Since the school zone was established in September 1995, school zone accidents have not decreased even though it has been strengthened through a total of nine revisions until January 2021. This paper aims to present a standard model for child protection zones based on disaster prevention design. Methods of research included literature research, empirical research, and cognition research. Awareness survey was conducted on children, parents and drivers. Environmental surveys included crosswalks, motorways, pedestrian roads, and traffic lights. The investigation found that visual recognition of school zones by vehicle drivers was difficult, and found that motorcycles using pedestrian roads were a very threat to children. Accordingly, improved school zone standard model design centered on disaster prevention design was presented.

Since hundreds thousands of pedestrians are killed or injured in car accidents every year, a variety of research efforts have been performed to protect pedestrians in pedestrian-vehicle crashes. The IHRA reports that injuries on the child head, the adult head, and the adult lower leg/knee are the most critical in the crashes. Identifying the current status of international activities on pedestrian protection, this study, in particular, carries out headform impact test using selected domestic vehicles categorized by three groups - Sedan, SUV (Sport Utility Vehicle), and 1 Box (One Box) Vehicle. According to the valuable findings from the test results, this paper proposes a methodology under which the Korean Technical Regulation for protecting pedestrians in pedestrian-vehicle crashes will be developed.

This study proposes a methodology to assess the traffic safety benefits of technical regulation for pedestrian leg. Traffic safety benefit is defined as the injury reduction in this study. Actual accident analysis and simulation experiments using LS-Dyna3d are conducted to establish statistical models for developing the methodology. The relationship between collision speed and parameters of the regulation is explored. An application example of the proposed methodology is also presented for more comprehensive understanding. It is believed that the proposed methodology would be greatly utilized in developing various technologies and policies to protect pedestrian.

Since the mid 1990s, policies have been actively promoted to improve safety and pedestrian environment around the school such as the improvement of School zone. However, the prevention of accidents was not effective because it did not extend to the school road where the main transportation route for children's commuting takes place. In addition, due to the rapid increase of automobiles, trunk road traffic in the peak time bypasses the back roads, which threatens children's safety and the environment by invading the school area, which is the main living space of children. In this study, the characteristics of domestic children's traffic accidents were investigated and the problems were analyzed by conducting a field survey on Yeouido Secondary School in Seoul and Unjung Elementary School in Gyeonggi Province. In addition, Variable speed limit signs and Beacons were installed in the pedestrian road of comunity including School zone, and the effects of facilities on the speed of vehicles were analyzed. As a result of the analysis, the Variable speed limit sign showed a deceleration effect of about 8.3km/h, and the Beacon showed a phenomenon in which the traveling speed of 0.8km/h increased only slightly. In addition, the traffic violation rate of passenger cars, buses, and lorries decreased by about 3% as a result of investigating the number of traffic violation vehicles before and after installation.

서울시내의 간선도로의 조명은 현재는 거의 국제수준에 준할 정도로 밝게 설비되어 있으나, 약 5년전만해도, 한나라 수도의 밤거리라고 하기에는 부끄러울 정도로 어둡고 컴컴한 거리었다. 도로조명은 시력의 감퇴를 초래하는 야간에 차량운전자나 보행자가 정확, 신속하고 평이한 시작업을 하므로서, 생명의 안전, 각종 교통화재방지가 사회생활에 편의을 도웁는데 있으므로 도로조명을 실시하는 경우에는 도시미관의 조성, 재산의 보호, 도로사용상의 결적성의 향상, 범죄의 예방등의 도시계획의 관점에서 고려되어야 한다. 본 측정, 평가 및 설계에는 미국조명학회(I.E.S.)에서 발행된 I.E.S guide for out door illumination test와 American standard practice for street and high way lighting을 많이 참고하였다.

기존의 엔진제어기(ECU)는 주요 mapping data(ECU에 대응되는 값)들에 대해서 기밀성과 무결성을 제공하는 보호 기법의 부재로 인해 임의적인 튜닝이 가능하다는 특징이 존재하였다. 이로 인해 자칫 잘못된 튜닝이나 악의적인 조작이 발생할 수 있는 여지가 있으며, 이는 차량 엔진 및 조작의 안정성을 떨어뜨림과 동시에 운전자 및 보행자들의 안전을 위협할 수 있다는 문제가 있다. 이에 본 논문에서는 ECU에 적용되는 Firmware의 주요 mapping data를 안전하게 암호화하는 방식을 제안하며, 이 과정에서는 차량의 식별 및 ECU에 mapping 되는 data의 무결성 검증을 위해 인증서를 사용하는 방식을 제안한다. 본 논문의 제안을 통해 주요 mapping data를 안전하게 보호하는 기술을 통해 차량의 안전성을 유지할 수 있다.

교통사고를 예방하고자 정부에서는 지속적인 정책을 펼치고 있으나 발생률이 크게 줄지 않는 실정이다. 본 논문에서는 이러한 한계점을 보완하고자 영상처리를 이용하여 교통사고를 줄일 방법을 제안하고자 한다. 우선 어린이 보호 구역 내에 설치된 카메라를 이용하여 교통사고 발생 위험을 판단하고, 보행자 및 차량 운전자에게 알려 줌으로써 교통사고 발생을 감소하고자 하는 시스템을 설계하였다. 또한 실시간 영상처리를 위해 관심 영역 지정, 멀티 스레드 등 다양한 방법을 적용해 보았으며, 위험 상황 탐지 시 탐지 결과를 주변 운전자에게 전송하려는 방법을 제시하고 실제 구현하여 확인해 보았다.
