Pedestrian involved accidents constitute a significant proportion of all traffic accidents, and the number of injuries per accident in pedestrian accidents is approximately three times the number of other types of traffic accidents. As with other types of accidents, pedestrian accident countermeasures can be applied to the human body, the vehicle and the environment, during the pre-crash, crash and post-crash phases. This paper is primarily concerned with reducing injuries to pedestrians through a study of the vehicle during the crash phase of pedestrian accidents.
