[Pedestrian traffic injuries--estimation of the speed of the colliding vehicle based on the extent of injuries in the pedestrian].

The authors assembled and analyzed a group of 101 fatal traffic injuries of pedestrians where the speed of collision was known and where a direct central collision occurred. Using criteria suggested by Fialka (1), the author quantified the injuries of pedestrians. A coefficient was revealed which lowers the score of fractures in old people. The author found a relationship between the quantity of the injury and the momentum of impact and calculated the relationship between the quantity of the injury and the momentum of impact. The author suggests a procedure for assessment of the probable speed of collision of the vehicle based on the injury of the pedestrian (p = 95%).
