Better crash cushions

A study in Italy has shown that short crash cushions can be safer and less expensive. Crash cushions are usually placed in front of metallic junctions near highways, tollbooths, or Jersey barriers. They are designed to mitigate the damage to passenger vehicles, reducing speed in case of impact. The standards of design and dimensions for crash cushions are classified by their speed level and capacity to redirect vehicles after impact. Crash cushions can either be sacrificial, which means they cannot be recovered after an impact and must be replaced, or reusable, which means they are designed to be recovered after impact. Reusable crash cushions can reduce costs, and a series of shorter crash cushions reduces the likelihood of impact for each cushion, which will extend the crash cushion's life cycle.
