Aging society may approached to our society during snatch very, and enter in super aging society for more span. Investment that we which live 21th century are many in people's quality of life elevation meantime did not consist, but stand in visual point that must improve many portions forward. For front, repletions for many equipments that consider aged on our society must consist, and much researches may have to be gone for this. According to traffic accident result, percentage of older pedestrian deaths was 46.5% as much in Korea. In particular, the crossing accidents by 59% or more of the older pedestrian traffic safety measures that target is an urgent situation. Therefore, in this study was to identify the domestic status and problem on no-sidewalk region for older pedestrians. In addition, side walk the installation and maintenance plan presented to prepare for aging society.

본 연구에서는 우리나라 교통안전수준의 제고를 위해 충청권을 대상으로 교통사고분석자료를 이용한 요인분석 및 군집분석과 설문조사를 실시하여 충청권 교통사고 특성을 분석하였으며, 분석결과를 토대로 충청권 실정에 맞는 교통안전기술을 개발하였다. 충청권 운송업자들을 대상으로 실시된 설문조사결과, 충청권의 주요사고 위협요인으로 '보행자 및 고령자 통행'과 '시인성 부족문제'가 가장 큰 것으로 나타났고, 가장 많이 필요로 하는 시설물로서는 '야간 운전시 조명시설'인 것으로 나타났으며, 시설물 설치로 인한 기대효과는 비교적 높을 것으로 나타났다. 또한, 교통사고분석자료를 활용하여 요인분석과 군집분석을 수행한 결과, 충청권의 도시유형별 사고특성은 도시형지역보다는 농촌형지역일수록 교통사고위험도가 높아짐을 확인했으며, 특히 보행자사고 및 농기계사고의 위험도가 높음을 확인했다. 따라서 본 연구에서는 분석결과를 토대로 충청권 교통안전수준의 향상을 위해 보행자 건널목 인식등, 교통약자 노견용 인식등, 농기계 운행 안전 LED전광판 등의 기술을 제안한다.

어린이는 행동적, 신체적 특성상 성인보다 교통사고에 노출될 가능성이 높기 때문에 안전한 보행환경을 조성하는 것은 매우 중요하다. 이에 이 연구에서는 교통사고분석시스템(TAAS)에서 제공하는 2016-2018년 서울시 보행자 교통사고 자료로 공간포아송 모형을 활용하여 어린이보호구역 주변 보행자 교통사고에 영향을 미치는 도로 및 교통안전시설의 특성을 분석했다. 주요 분석 결과는 다음과 같다. 첫째, 어린이보호구역 내 교차로가 많고 근린도로 비율이 높을수록 보행자 교통사고 발생 위험이 높아진다. 둘째, 보행자 작동신호기는 보행자 교통사고 발생을 줄이는 것으로 나타났다. 셋째, 이 연구에서 고려한 교통안전시설 중 보행자 작동신호기를 제외하고는 어떠한 교통안전시설도 보행자 교통사고 위험을 줄이는 데 효과가 없는 것으로 나타났다. 한편, 물리적 시설의 개선뿐만 아니라 교통안전교육 등 비물리적 요인이 뒷받침 된다면 어린이보호구역 내 보행자 교통사고 감소 효과는 더욱 극대화될 것으로 기대된다.

Traffic accidents due to excessive speed frequently occur in places where traffic signal controllers are installed, places where sharp curves exist, or places where the traffic signal cycle does not match the current time. These traffic accidents cause economic loss due to the destruction of road facilities and structures, and cause a big problem of increasing the number of traffic accident deaths. When a traffic accident occurs, leaving a tire mark before or after a car crash, pre-collision speed of the car is calculated using the law of conservation of momentum or the skid mark formula. In the skip skid mark generated in ABS brake vehicles and the combshaped yaw mark generated by tire trace caused by lateral sliding, there is a difference of 30-40% in the reliability of the vehicle speed calculated by the smite mark. In this paper, we propose an algorithm that can improve the calculation reliability in vehicle speed by using skid marks in order to compensate for this problem. In addition, we present an intelligent speed calculation algorithm for traffic safety and a computer simulation in order to prevent traffic accidents by estimating the speed of a vehicle, using Skid marks, Yaw marks, and ABS brake characteristics and fuzzy rules.

PURPOSES : The effects on traffic accidents change with the changing environment. Accordingly, this study analyzes the characteristics of traffic accidents based on the personal characteristics (gender and age) of drivers, and those of 25 autonomous districts in Seoul, and suggests improvements. METHODS : Based on data pertaining to traffic accidents in Seoul, the analysis of accident characteristics was conducted by categorizing the types of traffic accidents according to the drivers' gender and age, and characteristics of 25 autonomous districts in Seoul. Further, for statistical verification, the SPSS software was used to derive influence variables through a multinomial logistic regression analysis, and a method for reducing traffic accidents was proposed. RESULTS : Analysis results show that males tend to be more involved in speed-related accidents and females in low-experience driving-related accidents such as those during parking and alleyway driving. In addition, variables such as age, automobile type, district, and day of the week are found to influence accident types. CONCLUSIONS : This study analyzed the accident characteristics based on personal and city characteristics to reflect the sociological characteristics that influence traffic accidents. The number of traffic accidents in Korea could be decreased drastically by implementing the results of this study in customized safety education and traffic maps.

Purpose: A traffic signal controller needs to control and coordinate to ensure that traffic and pedestrians move as smoothly as possible. Since a traffic signal controller has a significant impact on the safety of vehicles and pedestrians, it is important to monitor the failure and deterioration of the traffic signal controller. The purpose of this paper is to propose an IoT (Internet of Things)-based monitoring system for a traffic signal controller. Methods: Every traffic signal controller has a nominal system trajectory specified when it is deployed. The proposed IoT-based monitoring system collects the system trajectory information through real-time monitoring. By comparing the nominal system trajectory and the monitored system trajectory, we are able to detect the failure and deterioration of the traffic signal controller. Conclusion: The proposed IoT-based monitoring system can contribute to the safety of vehicles and pedestrians by maximizing the availability of a traffic signal controller.

The vehicle motion in urban environment is determined by surrounding traffic flow, which cause understanding the flow to be a factor that dominantly affects the motion planning of the vehicle. The traffic flow in this urban environment is accessed using various urban infrastructure information. This paper represents a color recognition algorithm for traffic lights to perceive traffic condition which is a main information among various urban infrastructure information. Deep learning based vision open source realizes positions of traffic lights around the host vehicle. The data are processed to input data based on whether it exists on the route of ego vehicle. The colors of traffic lights are estimated through pixel values from the camera image. The proposed algorithm is validated in intersection situations with traffic lights on the test track. The results show that the proposed algorithm guarantees precise recognition on traffic lights associated with the ego vehicle path in urban intersection scenarios.

A rapid increase in traffic accidents involving senior vehicle occupants has been an issue in Korea because of the aging of the population occurring at one of the fastest rates in the world; unfortunately, few studies beyond several looking at the effect of senior occupants on the level of accident injury severity can be found in the literature. A Multinomial logit model was estimated with Newton-Raphson algorithm to perform bias-reducing penalized likelihood optimization. Model covariates integral to developing the model were included, but the main focus was on the interaction of seating position and injury to senior vehicle occupants. It was found that the likelihood of an accident resulting in a fatality increased: 2.2 times for the driver seat, 2.7 times for the front passenger seat, and even 6.7 times for the rear seat. A mandatory seatbelt law to be extended to the rear seat needs to pass the assembly as soon as possible, and government, industry, and safety groups should be encouraged to join forces to strongly carry out targeted campaigns for the wearing of seatbelts in all vehicle seats to enhance the safety of senior occupants as well as other occupants who are vulnerable to road traffic accidents.
