Field Evaluation of the Connecticut Impact Attenuation Device at Four High-Hazard Locations

摘要

In the latter part of 1984, the Connecticut Department of Transportation installed an experimental impact-attenuator known as the Connecticut Impact Attenuation System (CIAS) at four high-hazard locations. Some of the advantages of the system include ease of installation, ability to sustain any number of nuisance hits (hit and run) before replacement is required, and retention of attenuation characteristics when deformed and reshaped for reuse. This interim report, which is devoted to the field evaluation period from November 1984 to May 1986, describes the various types of impacts, maintenance requirements and problems encountered. During this evaluation period, no injuries to drivers or passengers have been reported, irrespective of the severity of the impact.
