Summary of the NCHRP Report 350 Crash Test Results for the Connecticut Impact-Attenuation System (CIAS)

This report on the Connecticut Impact-Attenuation System (CIAS) documents the National Cooperative Highway Research Program (NCHRP) Report 350 compliance of a Connecticut designed and developed impact-attenuation system. Background information about the system is also included, with information on previous crash testing, as well as the performance of field installation locations. Under the NCHRP Report 350, the system was initially classified as a redirective/nongating device. However, upon failure of the first test performed, the classification was modified to redirective/gating. NCHRP Report 350 specifies seven full-scale crash tests for redirective/gating devices. Two of the seven tests were not conducted on the CIAS because they are similar to tests conducted under the NCHRP Report 230 requirements, which the CIAS passed and one test, the reverse hit performance test, was not deemed necessary due to the locations where the systems will be used. The other four tests were conducted in accordance with the guidelines of NCHRP Report 350 for the Test Level 3 devices. The CIAS passed all requirements for the test designations. In 2002, the Federal Highway Administration approved the use of the CIAS on the National Highway System at locations where opposite-direction impacts are unlikely.
