Bibliography

Deals with the development of vehicle highway safety barriers in the United Kingdom. The term "safety barrier" includes those barriers installed using discrete post footings (post and rail types) as well as those on continuous ground footings (concrete or soil). Designs are concerned with the containment of vehicles ranging in mass from about 825kg to 38000kg. Controlled tests are specified for private car impacts at speeds up to 110km/h (70 mile/h) and commercial vehicle impacts at speeds up to 80km/h (50 mile/h).
