The Connecticut Impact-Attenuation System (CIAS) was developed by the Connecticut Department of Transportation (ConnDOT) in cooperation with the Federal Highway Administration (FHWA) to provide roadside safety in areas deemed high-hazard locations. These locations are along interstate highways, freeways and expressways in the gore area between the mainline and an exit ramp. The initial four locations were part of an experimental research project initiated in 1984 after the successful deployment of the Connecticut Truck Mounted Attenuator (CTMA). The CTMA was developed in 1975 to address the concerns ConnDOT maintenance personnel had of errant vehicles entering work zones along the roadside. Like the CTMA, the CIAS is based on the principle of dissipating kinetic energy by plastically deforming thin-walled steel cylinders that are loaded laterally upon impact. The steel cylinders are designed such that controlled energy dissipation could be achieved under impact with both light weight and heavy vehicles. This report gives a description of the system, presents the previous full-scale crash testing, as well as the requirements for evaluating the performance of these systems and their efficacy in terms of safety as addressed in the National Cooperative Highway Research Program (NCHRP) Report 350-Recommended Procedures for the Safety Performance Evaluation of Highway Features. Descriptions of the specific crash tests performed on the CIAS under the NCHRP Report 350 crash test criteria are also given.
