Samenvatting
This paper gives an overview of the crash cushions and terminals currently being used in the United States. This State-of-the-Practice paper discusses their crash test performance, construction and maintenance costs, and selection considerations. The emphasis is on practical information, selecting, locating and designing these safety devices. Both operational and experimental devices are covered. Most of the newer crash cushions and terminals are patented, proprietary devices. Therefore, some low-cost, non-proprietary systems such as breakway curved guardrails are also discussed. (A)
