The objective of the study described in this paper is to experimentally assess the pedestrian injury reduction potential of the front end of the Calspan RSV. A series of 16 experimental pedestrian impacts were conducted using an experimental set up and procedure developed in an earlier program. The test series consisted of impacts with two representative U.S. production vehicles (a 1974 Impala and a 1974 Vega) and the Calspan RSV—performance with both adult and 6-year-old child dummies was evaluated over a 20-25 mi/h speed range. Preliminary results indicate that acceleration levels of the head, chest, pelvis, and knee for both the adult and child dummies are significantly reduced (on the order of 50 percent) in impacts with the RSV. Major gains are indcated in reducing the acceleration of the pelvis and leg areas due to the inherent compliance of the RSV bumper. Based on the tentative results of this study, it appears that the injury attenuation performance of the RSV might increase the permissible impact velocity for a given level of injury by as much as 5 to 10 mi/h.
