Abstract
Pedestrian accident account for approximately 30% of fatal accident of traffic accident. Therefore, it is important to develop countermeasures of active safety or passive safety, for improving pedestrian safety, by clarifying reality of situation of damage. In this paper, author tried to clarify the relationship between collision velocity and injury level of[pedestrian by damaged region as statistical data by processing traffic accident data stored ITARDA(Institute for Traffic Accident Research and Data Analysis). In collision velocity less than 30km/h, frequency of slight injury by bruise, laceration or abrasion of legs is high. And in collision velocity over 50km/h, frequency of fatal or serious injury by fracture of head is high.
