Based on the proposed changes to the National Cooperative Highway Research Program (NCHRP) Report No. 350 guidelines, NCHRP Project 22-14(2) researchers deemed it appropriate to evaluate permanent safety shape barrier systems prior to finalizing the new crash testing procedures and guidelines. For this effort, the permanent New Jersey Safety Shape barrier was selected for evaluation. One full-scale vehicle crash test was performed on the longitudinal barrier system in accordance with the Test Level 4 (TL-4) requirements presented in the Update to NCHRP Report No. 350. For the permanent barrier testing program, a 10000S single unit truck was used. The permanent safety shape barrier provided an unacceptable safety performance when impacted by the single unit truck, thus failing to meet the proposed TL-4 requirements presented in the Update to NCHRP Report No. 350.
