Research on Application of Pedestrian Throw Distance Formula in GA/T643-2006

摘要

Based on CIDAS's resources of accident video data recording vehicles and pedestrians, this paper focuses on utilizing video image based calculating methods to research on application of pedestrian throw distance formula in GA/T643-2006. Our study shows that the results calculated from the pedestrian throw distance formula are partly inaccurate compared with actual car speed in cases that pedestrians are thrown after first collision with cars, and barely accurate to reflect the actual car speed in cases that pedestrians are thrown after second collision with cars. Therefore, it requires further adjustments on parameters identification and application scope of the pedestrian throw distance formula.
