This article discusses the various types of safety barriers existing and emphasises their inability to protect structures behind them, in certain circumstances. The use of rigid concrete barriers is discussed and reference is made to the tests carried out by the Transport and Road Research Laboratory with barriers of this type. The costing of the extra damage caused to vehicles and their passengers by concrete barriers is considered. Mention is made of the before and after study of barrier installation on stretches of motorway M1, resulting in the adoption and installation of the tensioned beam steel barrier. It is suggested that an improved design of concrete barrier might achieve the desired protection for vehicles and structures on motorways. (TRRL)
