The objective of the present study is to predict brain injuries and injury severities from realworld traffic accidents via in-depth investigation of head impact responses, injuries and brain injury tolerances. Firstly, a total of 43 passenger car versus adult pedestrian accidents were selected from .Reconstruction of PCDS (Pedestrian Crash Data Study) cases with laboratory impact tests and computer simulations for parameter sensitivity evaluation of proposed ISO and EEVC head impact test procedures.Pedestrian research and testing at the NHTSA Vehicle Research and Test Center has recently focused on assessment of proposed ISO and EEVC head impact test procedures, and extension of these .
severity versus impact velocity were all evaluated for the final PCDS and compared with the interim PCDS. FATALITY ANALYSIS The influence of vehicle body type, impact velocity, pedestrian orientation relative to the vehicle, and pre-impact pedestrian motion on the occurrence and nature of pedestrian fatalities was examined and compared withgiven vehicle class in PCDS than GIDAS, based on these impact speed and pedestrian age distributions (see Table I). For cars, the AIS2+ injury rate in PCDS is 2.1 times that in GIDAS, and higher again for the head (3.1 times).Research & Test Center (VRTC) for developmental testing with the HYGE Impact Simulator (Transportation Research Center, Inc.). Two PCDS (Pedestrian Crash Data Study) cases, involving a low (1999 Honda Civic) and high (1991 Chevrolet Silverado) front-end profile, were selected from this database for reconstruction using the Polar II dummy.
