Pedestrian Injuries Induced by the Bonnet Leading Edge in Current Car-Pedestrian Accidents

The objective of this research is to clarify the significant factors causing AIS 2+ femur or pelvis pedestrian injury, and to understand whether the current EEVC upper legform test reflects real world pedestrian accidents. An in-depth case study was conducted using the selected 82 pedestrian accident cases from 1987 to 1997 in the data base of Japan Automobile Research Institute (JARI) and Institute for Traffic Accident Research and Data Analysis (ITARDA).

The results indicate the significant factors were the bonnet leading edge height, the vehicle registration year and the pedestrian age. The bumper lead was not a significant factor. However, the test condition of the EEVC upper legform test depends on the bumper lead and the bonnet leading edge height. The current test condition of the EEVC upper legform test should be reconsidered excluding the bumper lead.
