This study aims to analyze safety indicators for various types of pedestrian accidents (traffic accidents, crimes, crowd crush incidents, and falls) in urban community roads. The need for this research arises from the complexity and narrowness of these streets, which significantly threaten pedestrian safety. The study employed literature reviews, case studies, and field surveys to identify risk factors for pedestrian accidents. These risk factors were then systematically evaluated using the Analytic Hierarchy Process (AHP) to determine the relative importance of each safety indicator. The analysis revealed that for traffic accidents, factors such as the separation of pedestrian and vehicle paths and the effective sidewalk width are critical. For crime-related incidents, lighting and CCTV coverage were found to be the most important. In crowd crush incidents, pedestrian traffic volume and effective sidewalk width were identified as key indicators, while slope and effective sidewalk width were crucial for preventing falls. These findings contribute to the development of targeted safety improvement measures for urban community roads.

Walking is an eco-friendly and sustainable means of transportation that promotes health and endurance. Despite the positive health benefits of walking, pedestrian safety is a serious problem in Korea. Therefore, it is necessary to investigate with various studies to reduce pedestrian-vehicle crashes. In this study, the cognitive characteristics affecting pedestrian-vehicle crashes were considered by applying deep learning semantic segmentation. The main results are as follows. First, it was found that the risk of pedestrian-vehicle crashes increased when the ratio of buildings among cognitive factors increased and when the ratio of vegetation and the ratio of sky decreased. Second, the humps were shown to reduce the risk of pedestrian-related collisions. Third, the risk of pedestrian-vehicle crashes was found to increase in areas with many neighborhood roads with lower hierarchy. Fourth, traffic lights, crosswalks, and traffic signs do not have a practical effect on reducing pedestrian-vehicle crashes. This study considered existing physical neighborhood environmental factors as well as factors in cognitive aspects that comprise the visual elements of the streetscape. In fact, the cognitive characteristics were shown to have an effect on the occurrence of pedestrian- related collisions. Therefore, it is expected that this study will be used as fundamental research to create a pedestrian-friendly urban environment considering cognitive characteristics in the future.

In order to secure pedestrians' right to walk, we have up-cycled second hand mobile phones to overcome limitations of the existing survey methods, analysis methods, and diagnosis to reduce pedestrian traffic accidents. Second hand mobile phones were up-cycled to produce mobile CCTVs and installed in areas where pedestrian deaths rate is high to secure image data sets for the period of more than 24 hours. It was analyzed by applying image visualization technology and clouding reporting technology, and more precise and accurate results were derived through modeling based on artificial intelligence learning and GIS-based diagnostic guidance. As a result, it was possible to analyze the risk factors and number of pedestrian safety, and even factors that were not known in the existing method could be derived. In addition, the traffic accident risk index was derived by converting data into one year to verify whether second hand mobile phone up-cycling mobile CCTV will be an objective tool for finding pedestrian risk factors. Up-cycling mobile CCTV of second hand mobile phones newly applied through research can be used as a new tool to find pedestrian risk factors, and it can be used as a service to protect the safety of the traffic vulnerable other than pedestrians.

일반적으로 교차로에서의 보행자 사고는 대부분이 횡단보도에서나 횡단보도 주변에서 발생하는 것이 많다. 이것은 운전자의 안전의식부족뿐만 아니라 보행자들이 교통법규를 지키지 않기 때문이다. 교통사고는 운전자나 보행자를 막론하고 안전의식 수준 및 안전시설의 질적 수준과 밀접한 관련이 있다. 특히 횡단보도 위치와 관련한 정지선에 대한 기준이 없어서 횡단보도 전후에 정지선이 2개가 설치된 곳이 많아 차량간의 사고를 유발하고, 보행자는 보행동선을 단축하기 위해 횡단보도 주변횡단이라는 위험한 행태를 유발하지만 이에 대한 연구나 대안제시가 이루어지지 않고 있다. 본 연구는 요인분석법이란 다변량 통계기법을 통해서 사고기록과 형태자료를 분석하였다. 사고기록은 정지선이 2개에서 1개로 변경된 25개 교차로에 대한 보행자와 차량의 유형별, 위치별, 피해정도별 사고기록을 조사 분석하고 행태분석은 현재 정지선이 2개인 곳과 기하구조가 유사한 정지선 1개인 곳을 하나의 쌍으로 해서 모두 8쌍(16개의 교차로 횡단보도)를 조사 분석하였으며, 마지막으로 설문조사를 통해서 보행자의 교통법규 준수와 인식정도에 대한 조사를 통해 보행자들의 인식과 행태조사를 통한 교통법규 준수 정도를 알아보았다. 사고자료의 분석을 통해서 첫째, 정지선이 2개인 교차로는 교차로내 차량사고, 접근부의 후면 추돌사고, 횡단보도에서 보행자사고가, 둘째, 정지선이 1개인 교차로는 유출부 차량사고가 많은 것으로 나타났으며, 행태자료의 분석을 통해서는 첫째, 정지선이 2개인 곳은 횡단보도를 이탈 또는 진입하면서 횡단하는 보행자, 점멸신호에 횡단 시작하는 보행자의 행태와 보행자 신호에 횡단보도를 통과하는 차량, 둘째, 정지선이 1개일 때는 횡단보도를 침범해서 정지하는 차량, 도로에 내려서서 기다리는 보행자가 많은 것으로 나타났다. 마지막으로 설문조사와 행태조사를 종합하면, 보행자들의 인식으로는 약 71%의 응답자와 점멸신호의 의미를 알고, 전체 응답자의 약 58%가 점멸신호에 건너지 않고 기다린다는 응답(교통법규준수)을 했으며, 실제 행태에서는 약 12.4%가 위반하는 것(87.6% 법규준수)으로 나타났다. 보행자들이 응답한 것보다 실제 행태에서는 더 많은 보행자가 교통법규를 준수하는 것으로 나타났으며, 횡단보도를 이용하는데 있어서 횡단보도를 침범하는 차량과 신호시간이 적다는 의견이 많았다.

On roads vehicles are the bossy, while pedestrians are the frangible. The current paper has a purpose for contributing to pedestrian's safety. First, it studies the association between demographic parameters and TPB(Theory of Planned Behavior)'s variables(pedestrian's attitude toward crossing behavior in roads, personal norm, etc.) and his/her crossing intention, perceived risk while crossing, and the experience of past traffic accidents. Its sample comes from a specific population(college students). Further, the present study endeavors to explain the portion of human cognitive failure/error, impulsiveness, time perspective, and probabilistic/math-logical judgment ability in pedestrian's riky crossings on roads. Research results found that TPB variables and such a few human characteristics have some significant association with the risky crossing intention on the road. Considering the human psychological portion in pedestrian accidents would help us prevent the accidents and reduce unhappiness of the accidents and, further, economic loss and insurance expenditure related with the accidents.

It is very important to build a safe walking environment for children because children are more likely to be exposed to traffic accidents than adults due to their behavioral and physical characteristics. Therefore, this study analyzed the characteristics of road and transportation safety facilities that affect pedestrian traffic accidents around school zones using spatial poisson regression. The pedestrian-vehicle crash data in Seoul 2016-2018 was provided by the Traffic Accident Analysis System(TAAS). The main analysis results are as follow; First, the more intersections and the higher percentage of neighborhood roads in the school zone, the higher the risk of pedestrian traffic accidents. Second, the pedestrian push button was found to reduce the occurrence of pedestrian traffic accidents. Third, except for the pedestrian push button, none of the transportation safety facilities considered in this study were effective in reducing the risk of pedestrian traffic accidents. On the other hand, if not only the improvement of physical facilities but also non-physical factors such traffic safety education are supported, the effect for reducing traffic pedestrian traffic accidents in the school zone is expected to be further maximized.

Community roads pose risks for traffic accidents, falls, crimes, and disasters, threatening pedestrian safety. However, current road management and safety systems primarily focus on arterial roads, and fail to adequately consider the unique characteristics of community roads. This study presents a methodology to more effectively predict various pedestrian accidents on community roads by categorizing risk zones based on a distribution of risk factors. Through field surveys, key risk factors for each type of accident were identified, and the frequency of these factors was used to classify risk zones, which were then visually represented using GIS. Applying this methodology to Seoul's Seocho 1-dong, a comparison with actual accident data revealed a partial correlation between the predicted risk zones and actual locations of traffic and disaster-related incidents, thereby validating the methodology. This study is expected to serve as a policy tool for preventing accidents and enhancing safety on community roads.

Police agency is indicated that the number of children's traffic accident is tending downwards, however about one child is dead every day due to traffic accident. Major parts of the accidents happen during walking; among the rest, jaywalking is the biggest reason. Many accidents take plate on the road to school or near the home so government legislate children safeguard zone at 1995. According to the legislation, drivers have to reduce speed and there are safety facilities for children at children safeguard zone. This study finds the problems of children safeguard zone and suggest more effective and quantitative method for children safeguard zone. Firstly this study grasps the characters of children's pattern movement and children's traffic accident at children safeguard zone and then divides specific danger factors of children's traffic accident at children safeguard zone. Secondly, each factor is given danger level depending on danger degree and suggests effective method for assignment standard of children safeguard zone using all of these things.

This study analyzed traffic accident characteristics in Chungcheong Region through the factor analysis, cluster analysis and questionnaire survey using traffic accident analysis data for Chungcheong Region in order to improve Korea's traffic safety level. Based on the analysis results, this study suggests traffic safety technologies suitable for the situation of Chungcheong Region. According to the results of the questionnaire survey carried out for transporters in Chungcheong Region, 'the passage of pedestrians and aged people' and 'a problem of lacking visibility' were the biggest threatening factors of major traffic accidents in Chungcheong Region. The facilities required the most were 'lighting equipment in driving at night', and the expected effect by the equipment installation was high. As a result of the factor analysis and cluster analysis using the traffic accident analysis data, traffic accident risk by city type in Chungcheong Region was higher in rural areas, compared to urban areas. Especially, this study confirmed the risks of pedestrian and agricultural machine traffic accidents were high. Therefore, this study suggests three technologies to improve traffic safety level in Chungcheong Region, based on the analysis results.
