The purpose of this study is to analyze the relationships between the traffic accidents of elderly pedestrians and barrier-free facilities in the case of Cheongju. First, many accidents of elderly pedestrians were determined to occur in the road and during crossing. Second, the correlation analysis shows that the paving conditions, guiding blocks and embossed blocks have impacts on elderly safety. Finally, the logistic regression model, which is statistically significant (chi-square =0.000, Nagelkerke =0.198), was developed, and includes the paving conditions, bollards, audible signals and remaining time signs as the independent variables. The variables, with the exception of the existence of bollards, are all analyzed to have positive impacts to elderly safety.

This study aims to identify the throw distance in terms of truck weight, bumper height, and speed in a truck and pedestrian collision, and to propose a model for throw distance estimates. For this purpose, a simulation analysis is performed using the PC-crash program with the following experiment conditions: Truck weight of 5t, 15t, and 25t, Bumper height from 0.3m to 0.6m by 0.1m, and speed from 10km/h to 100km/h by 10 km/h. Experimental results show that the truck speed and bumper height are found to be significant factors for pedestrian throw distance, but truck weight is not a significant factor. Also, a regression model is developed for pedestrian throw distance estimate from the multiple regression analysis. The adjusted $R^2$ value of the model is 93.3%, which is very good explanatory power.

There are no specific criteria deciding what type of crosswalk installs although 4 typed crosswalks at signalized intersections classify according to number of stop line, spacing from the border of intersections and existence of traffic islands or not. Accidents involving pedestrians at signalized intersections are classified by type of crosswalks by traffic volume, pedestrian volume at crosswalk, intersection geometry and phase in view of pedestrians' safety at 50 intersections in Gwangju. The Multiple regression models are applied to express the pedestrian accident rate. In addition, process deciding what type of crosswalk installs which includes accident rate involved pedestrian is changed into number of accident is represented to reduce number of accidents. This paper presents what type of crosswalk installs in order to reduce pedestrian involved accidents at new or existing crosswalk.

The characteristics of elderly traffic accidents were identified by reflecting the situation of the elderly population in Korea, which is entering an ultra-aging society, and the relationship between independent and dependent variables was analyzed by classifying traffic accidents of serious or higher and traffic accidents of minor or lower in elderly pedestrian traffic accidents using binomial variables. Data collection, processing, and variable selection were performed by acquiring data from the elderly pedestrian traffic accident analysis system (TAAS) for the past 10 years (from 13 to 22 years), and basic statistics and analysis by accident factors were performed. A total of 15 influencing variables were derived by applying the logistic regression model, and the influencing variables that have the greatest influence on the probability of a traffic accident involving severe or higher elderly pedestrians were derived. After that, statistical tests were performed to analyze the suitability of the logistic model, and a method for predicting the probability of a traffic accident according to the construction of a prediction model was presented.

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.

Purpose: The purpose of this study is to analyze the walking characteristics of jaywalking pedestrians, which account for a large proportion of deaths in pedestrian traffic accidents. Method: As for the analysis method, after collecting data of jaywalking pedestrians using imaging equipment, frequency analysis and statistical verification were performed on the jaywalking characteristics of elderly and non-elderly people. Result: It was found that there was a difference in the characteristics of jaywalking between the elderly and non-elders, but in the case of walking speed, insignificant results were derived. However, it was found that among the elderly, the group having difficulty walking in general had a lower walking speed than the group that did not. Conclusion: It is judged that one of the causes of jaywalking is the perception of illegal activities and insensitivity to the risk of accidents, not the age and walking ability. Therefore, in addition to safety education, it is judged that it is necessary to provide pedestrian safety information that requires the driver's attention in multiple jaywalking sections.

Korea had the highest accident rate among OECD countries in 2018, with 8.4 per 100,000 population, ranking 4th among 35 countries. In addition, the accident rate of traffic with children and the elderly was also high. This study reviewed the relevant literature and analyzed the traffic-accident analysis system. Customized traffic safety facilities were developed. In addition, by measuring the visibility of the traffic safety facilities by installing a test bed, this study measured the forward driving frequency and vehicle driving speed while driving. As a result of applying the "pedestrian pedestrian model" collision test model, the possibility of serious injury after installing the facility was reduced greatly to 4.6%. In this study, the visibility of traffic safety facilities and the effect of reducing the traffic speed were verified through test beds. Recognizing traffic safety facilities will reduce traffic accidents.

최근 교통에 대한 관심도 환경보호와 건강의식이 강화됨에 따라 차량 중요성이 강조되던 시대에서 보행자의 안전과 편리중심으로 바뀌고 있다. 그러나 최근 수년간 발생한 교통사고 사망자 중 40%가 보행자이고, 이 수치는 OECD에서 가장 높은 수준이다. 본 연구는 방재디자인기반의 보행자 안전사고 예방을 위한 횡단보도 안전표지디자인 가이드라인 연구로 디자인 전문가 10명을 대상으로 심층면접을 통해 디자인 문제점을 발견하고 현재의 횡단보도안전표지를 개선방안을 제시하였다.

최근 전체 교통사고 보행 사상자 중 우회전 차량에 의한 보행 사상자의 비율이 2018년 9.6%, 2019년 10%, 2020년 10.4%로 증가세에 있다. 현재는 이러한 상황을 해결하기 위해 국토교통부에서는 2022년부터 보행자 보호 의무 위반 운전자에게 최대 10%의 보험료 할증을 부과하고, 경찰청은 '교차로서 일단정지'를 골자로 하는 도로교통법 개정안을 공포하고 2022년 7월 12일부터 시행한다고 밝혔다. 본 논문은 이러한 상황에서 운전자나 보행자 모두가 안심할 수 있도록 하는 '보행자 안전을 위한 횡단보도의 구현' 기술을 제안한다. 법체계가 아닌 바리케이드와 초음파 거리센서, 압력센서 등을 활용한 물리적인 시스템으로 운전자들의 혼란을 해소하고 보행자들이 안심하고 건널 수 있는 횡단보도를 구현하여 최근 증가하고 있는 우회전 보행자 사고를 예방 할 것이다.

To establish objective criteria for high pedestrian accident zones, we combined Getis-ord Gi* and Kernel Density Estimation to select high pedestrian accident zones for 54,208 pedestrian accidents in Seoul from 2009 to 2013. By applying Getis-ord Gi* and considering spatial patterns where pedestrian accident hot spots were clustered, this study identified high pedestrian accident zones. The research examined the microscopic distribution of accidents in high pedestrian accident zones, identified the critical hot spots through Kernel Density Estimation, and analyzed the inner distribution of hot spots by identifying the areas with high density levels.
