THREE (3)-YEAR FIELD EVALUATION OF THE NARROW CONNECTICUT IMPACT-ATTENUATION SYSTEM (NCIAS). FINAL REPORT

In a continuing effort to develop and implement the use of improved vehicular crash cushions, the Connecticut Department of Transportation has designed, crash tested and field evaluated a new and unique device, known as the Narrow Connecticut Impact-Attenuation System (NCIAS). By employing eight (8) steel cylinders connected in a single row as its energy-absorbing medium, the NCIAS is designed to protect motorists from impacting narrow, rigid roadside features, such as bridge piers and ends of longitudinal barriers. This report documents a comprehensive three (3)-year field evaluation of five (5) NCIAS installations in Connecticut. During the evaluation period, one (1) major and several minor impacts occurred. The NCIAS performed successfully in all instances.
