On the Staggered Crosswalks, pedestrians cross the crosswalks two times. This method can reduce the cycle, the vehicle delay and the walking distance by increasing the major direction of green time. The safety of pedestrians is also effective. This study suggests the warrant of the facilities of island width and length etc. by considering the road structure and pedestrians. Also this study suggests the standard of the safety through the accident analysis of Staggered crosswalks and General Crosswalks. In the results, accident rate of the Staggered Crosswalks 18.3(100 million vehicle-km) was lower than the accident rate of the General Crosswalks 28.3(100million vehicle-km). By understanding the start point of crossing of the Staggered Crosswalks, the analysis of the location and types of accident suggests the safety zone(spare space). The setting warrants of Staggered Crosswalks are 4 lane over the road and the 2 meter over sidewalk width of island. The minimum length of the Pedestrian island was doubled compared to the crosswalks width. And the maximum length was set by considering the wait time of the pedestrians.

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.

The objective of this study is to develop a methodology for evaluating the effectiveness of in-vehicle pedestrian warning systems. Driving Simulator-based experiments were conducted to collect data to represent driver's responsive behavior. The braking frequency, lane change duration, and collision speed were used as measure of effectiveness (MOE) to evaluate the effectiveness. Collision speed data obtained from the simulation experiments were further used to predict pedestrian injury severity. Results demonstrated the effectiveness of warning information systems by reducing the pedestrian injury severity. It is expected that the proposed evaluation methodology and outcomes will be useful in developing various vehicular technologies and relevant policies to enhance pedestrian safety.

Pedestrians are the most vulnerable road users. According to one analysis of traffic accidents over a five year period, pedestrians accounted for about 40% of all road traffic deaths in South Korea. Although some policy and engineering approaches have been taken to reduce and prevent traffic accidents, the annual accident change rate is -0.7%, which is insufficient. This study verifies the effectiveness of presenting visual messages to pedestrians and the effect from adding auditory messages to the visual messages. The experiment was conducted on crosswalks adjacent to an intersection, and safety behaviors were recorded for a total of 898 pedestrians and considered sufficient. As a result of the study, overall pedestrian safety behavior improved when both visual and auditory messages were presented, rather than just visual messages. Therefore, the results indicate it is more effective to provide a mixed visual/auditory form of messages, rather than providing single stimulus messages.

In recent urban policies, the importance of 'health' has increased significantly. In Korea, the deterioration of physical health due to environmental problems caused by rapid urbanization and the deterioration of mental health due to the disconnection of social relations in a competitive society are constantly occurring. this study aims to examine the effect of the satisfaction and safety recognition on pedestrian environment on the subjective health status focused on gender difference of the intermediating effect of social capital. I used 2018 Seoul Survey and employed Structural Equation Model multi-group analysis. According to the empirical analysis, in male groups, the satisfaction and safety recognition on the pedestrian environment affect social capital. Also, satisfaction and social capital affect subjective health status. On the other hand, in female group, perception of pedestrian environment affect social capital. In addition, satisfaction, safety recognition and social capital affect subjective health status. Therefore, interdisciplinary study in the field of health and urban policy and discriminatory policy for strategic urban policy for citizen's health is necessary.

대한민국은 곧 초고령사회에 진입할 것으로 전망된다. 국내 신호 교통체계에서 교통약자에 해당하는 고령자의 보행 안전성은 취약한 상태이다. 이에 본 논문에서는 고령자와 기타 교통약자의 보행 안전성을 높이기 위해 초음파 센서와 적외선 센서를 사용한 스마트 신호등을 제안한다. 제안하는 시스템은 교통약자가 인식되면 보행신호 시간을 연장하여 횡단보도에서의 보행자 사고율을 감소시킬 수 있다.

보행의 제한은 시각장애인의 자립적인 생활을 어렵게 하며 안전에도 큰 영향을 끼친다. 본 논문은 YOLOv5(You Only Look Once version 5)를 활용하여 안전한 보행을 돕는 방법을 제시한다. 제시하는 방법은 자동차나 자전거, 전동킥보드 등의 움직이는 사물과 사람을 실시간으로 인식하여 시각장애인에게 알림으로써 보행에 도움을 줄 수 있으며 시각장애인의 안전한 보행에 도움을 줄 것이라 기대한다.

유모차 사고는 추락/넘어짐/미끄러움으로 인해 발생하는 사고가 가장 큰 비율을 차지한다. 또한 보행이 불편한 고령자가 유모차 또는 보행기를 보조기구로 사용할 때에도 유모차와 유사한 사고 발생 확률이 높다. 기존의 유모차, 전동 휠체어, 보행기 등 출시 제품들은 넘어짐과 관련된 사고예방 기능은 구현되지 않았으므로 사고를 예방하기 힘들다. 이를 해결하기 위해 본 연구는 기울기에 따라 보행 중 안전을 보조하고, 속도에 따른 넘어짐 관련 사고를 예측하여 보호자 및 주변 사람들에게 위험을 알리는 사고예방을 위한 보행보조시스템을 설계하고 구현하였다. 이 시스템을 통해 유아 및 고령자가 이용하는 보행보조기를 더욱 안전하게 사용하여 2차 사고를 예방할 수 있는 효과를 기대할 수 있다.

The aim of this study was to suggest an enhancement of pedestrian safety through a service design process regarding urban design in new-town area. For this study, the concept, process and touchpoint, and survey design area, of the service design are reviewed as a theoretical study. According to this study, traffic signals, pedestrian environment, pedestrian overpass, and access traffic road were surveyed as touchpoints and a problem search, concept design, design building, institutional implement were analyzed as a service design process. As a result of these studies, the planning method for pedestrian safety based on service design process in terms of the external space design in a new-town area are suggested.

Traffic islands were introduced for drivers and pedestrians to use the road in a safe and orderly way and were also a specified zone between traffic lanes to divide conflicting traffic flows and to provide pedestrian refuge. However, existing research and relevant standards described its purpose and effects only but not a safety standard to decide whether the traffic island warranted. This study was to introduce a parameter which had a high relationship with accidents by analyzing road and traffic conditions and traffic accident data at urban intersections. Based on the relationship between the parameter and the traffic accidents at the intersection, a pedestrian accident probability model was made by using a logit model. In addition, the study reviewed a pedestrian accident probability corresponding to traffic volume and size of the intersection during design of the intersection and then suggested the effectiveness of the traffic island in terms of traffic safety. In conclusion, when a large-scale intersection has significant traffic volumes, a high probability of traffic island-induced pedestrian accidents appears, while in the case of small volumes, the probability is low. Targeted design and operations of a traffic islands is necessary, because its introduction itself does not enhance pedestrian safety in all cases at all intersections. This study can be a useful reference for further development to set up a scheme of the traffic islands in terms of traffic safety.
