Abstract:

The development of a new crash cushion is described. This impact-attenuation device is composed of steel tubular members formed from straight plate sections, which are bolted together to form a cluster. This device is unique in that it will trap an errant vehicle under most impact conditions. The vehicle will be redirected back out into the roadway only when the impact location is so close to the rear of the system that it is impossible to obtain acceptable energy-dissipation and deceleration-trapping responses because of the proximity of the site hazard. No other attenuation system in use today possesses this capability. In addition, the Connecticut impact-attenuation system exhibits the following characteristics: (a) it satisfies the impact performance standards outlined in Transportation Research Circular 191 and NCHRP Report 230, (b) it is inexpensive to fabricate, (c) the energy-dissipating tubes can be refurbished after impact and reused, (d) there is no flying debris associated with the crash event, and (e) it is constructed of readily available materials.
