심각한 노인교통사고를 줄이기 위하여 가장 높은 점유율을 보이는 노인보행자의 횡단사고 유형, 특성 및 사고원인을 분석했다. 횡단사고의 약 60%가 횡단보도 및 그 부근에서 발생했고, 70%이상이 노인여성이었으며, 절반정도가 야간에 발생했고 피해정도는 치사율이 12%, 부상은 평균 6주의 중상이었다. 사고원인은 특히 횡단보도 및 그 부근에서의 운전미확인이 가장 많았고, 노인보행자측의 원인은 고의위반 또는 법의 부지가 가장 많았다. 노인보행자의 횡단사고를 줄이기 위해서 운전자에게 횡단보도 정지선 엄수, 횡단보도 부근뿐 아니라 생활도로 및 상업지역 도로에서의 철저한 안전확인 등의 교육, 홍보, 훈련이 필요하다. 노인보행자를 위한 훈련프로그램은 성별로는 특히 노인여성에게 집중적 훈련이 요구되며, 훈련내용으로는 야간횡단의 위험성 인식 및 반사재 부착, 안전한 횡단장소 선택 및 횡단절차의 훈련, 상대방은 운전자와의 의사소통 훈련 등이 중점적으로 개발되어야 한다.

자동차를 설계할 때에는 예술적, 기술적으로 뛰어나다 하더라도 공학적으로 실현이 가능하여야 한다. 또한 비용이라든가 품질도 중요한 고려사항이다. 하지만 이것들 보다 자동차 설계에서 더욱더 중요시되는 것은 안전이다. 사고 시 사람의 생명을 최대한 안전하게 보호할 수 있는가이다. 이번 연구는 'Design for Safety' 중에서도 보행자 안전을 고려한 자동차 설계에 관해 연구하고자 한다. 2005년 교통사고 통계에 따르면 차대사람의 사고발생건수는 총 46,594건에 사망자 2,457명 부상자 47,282명이다. 이는 한 해 전체 교통사고 발생건수에 21.8%를 차지하고 있다. 본 연구는 자동차 사고 중 보행자와 차량의 사고 유형과 상해부위를 파악하여 사례를 중심으로 살펴본 후 이를 자동차 설계에 반영하는 방법에 대한 연구이다.

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.

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.

A pedestrian accident is generally less fully understood than the 'typical' car-to-car collision. For this reason, the analysis of the pedestrian accident is, in many respects, more complicated and demanding. The purpose of this study is to identify clearly the impact point that is the main subject of struggle in pedestrian accidents. In order to develop the model, it is very significant to classify actual accident data including impact velocity. vehicle damage and injury scale of pedestrian. These data were collected from three local branches of RTSA(Road Traffic Safely Authority). The number of collected data were 34 cases and 61.7% of them were fatal accidents. In consequence of analyzing the data by statistical method, it revealed that there is correlation between impact velocity and throw distance. It, also shows that the impact velocity has strong linear correlation to vehicle damage and injury scale. Consequently, reconstruction analysis models of pedestrian accidents considering in local circumstances(such as the physical characteristics of pedestrians and vehicles) was developed However. it is difficult to apply the result of this study to all sorts of pedestrian accidents, because the actual accident data which were used to develop the model were limited. To overcome this limitation, it is necessary to develop an analysis model applicable to diverse circumstances with a wide range of pedestrian accident data on a national basis.

This Paper presents the severity analysis result of the year 2006 national pedestrian crashes using the data base of 37,589 records prepared for the National Police Bureau. A set of attributing factors considered to affect pedestrian crash patterns were selected, and their contributing effects were investigated by applying the Ordered Logit Model. This model was selected because this model has been able to afford satisfactory results when the dependent variable involved ordered severity levels; fatal, injury, and property- damage-only in this investigation. The investigation has unveiled the followings; First, the pedestrian crash patterns were dependent upon human -drivel and pedestrian- characteristics including gender, age, and drinking conditions. Second, other contributing factors included vehicle, roadway geometric, weather, and hour of day characteristics. Third, seasonal effect was not contributive to crash patterns. Finally, the application of the Ordered Logit Model facilitated the ordered severity level analysis of the pedestrian crash data. This paper concludes that conventional wisdom on the pedestrian crash characteristics is largely truthful. However, this conclusion is limited only to the data used in this analysis, and further research is required for its generalization.

This study presents comparison results for pedestrian accident reconstruction models representing the relationship between collision speed and horizontal distance that a body travels while falling and sliding. A set of 49 reliable pedestrian accident cases are applied to compare the existing reconstruction models. In addition, the authors investigate the effects of a set of parameters associated with the effects of the frontal shape of a vehicle on the horizontal distance a pedestrian travels while falling and sliding. It has been revealed that the length of the bumper is the most dominant factor to affect the horizontal distance of pedestrian travel after collision. Further analyses utilizing more accident data need to conducted to develop a more accurate and reliable reconstruction model.
