The study investigated the impact performance of inertial barrel and GREAT impact attenuator systems using full scale crash testing of small and large test vehicles. In all, 20 tests were performed: 16 with inertial barrels and 4 with GREAT system. The 16 inertial barrel tests studied large car versus small car, angled versus head-on positions, pea gravel versus sand fill material, frozen versus nonfrozen crash tests, loose sand versus bagged sand and two different brand attenuator barrels. The four GREAT tests using a six-bay system studied head-on versus angled positions and large car versus small car impacts. Results of the program showed small car performance to be generally acceptable when using NCHRP 230 and dummy analysis procedures. The large car produced higher decelerations and in some cases the values exceeded the limits specified.
