Two kinds of parapets of British Aluminium Co are specified -- P1 barrier for roadway underbridges which is able to contain 30 cwt vehicle striking it at 70 mph at angle of 20°, and P2 system for roadway overbridges where demands are similar except that speed limit is reduced to 50 mph; design of systems is so arranged that at predetermined load posts fail, thus allowing rails to absorb impact energy from vehicle by stretching or elongating.
