The Connecticut Impact Attenuation System (CIAS) is a crash cushion that is re-directive, gating. The CIAS is tested under NCHRP Test Level 3 standards. The impact-attenuation device is composed of steel tubular members formed from straight plate sections, which are bolted together to form a cluster. The CIAS systems used in Ontario consist of 14 steel barrels with varying wall thickness. This system is ideally suited for gore hazards, where opposite direction impacts are not a concern.
