Book excerpt: National Cooperative Highway Research Program (NCHRP) Report 350 test designation 3-34 on the Connecticut Impact Attenuation System (CIAS) was performed under an ongoing Federal Highway Administration (FHWA) contract in which the Narrow Connecticut Impact Attenuation System (NCIAS) was being evaluated to NCHRP Report 350. The contract for this study called for up to seven full-scale crash tests to be performed on the NCIAS. In lieu of the last test under this contract, Connecticut DOT and FHWA agreed to replace the test on the NCIAS with a test on the CIAS. This report summarizes the results of NCHRP Report 350 test designation 3-34, with the 820-kg vehicle impacting the CIAS at the critical impact point (between the end of the cushion and the beginning of the length of need). The CIAS performed acceptably for all specified criteria except the longitudinal ridedown was marginal, 20.5 g's compared with the limit of 20 g's specified in NCHRP Report 350.
