While barriers are normally designed to minimize injury to vehicle occupants, injuries do occur in collisions with traffic barriers.They should only be installed where a collision with the barrier is likely to be less severe than a collision with the hazard behind it.
While traffic barriers(which is also known as”แผงกั้นจราจร” as in the Thai language) are typically designed to minimize problems for vehicle occupants, injuries usually happen in crashes with traffic hurdles.Where possible, it’s better to remove, relocate or change a hazard, rather than simply shield it with a barrier.
They should only be installed at which an accident with the obstruction is likely to be severe than the usual collision with all the danger supporting it.Additional country highways followed lawsuit to embrace such measures, which stayed the typical specification for hurdles for centuries.
But although the range of accidents paid off, they happened when trucks scaled those hurdles.After experimentation with different specifications of width and height over the median hurdles, new jersey highway engineers observed that the decrease in accident costs, with all taller hurdles.
They finally settled on the 3 2 inches high and 24 inches wide parabolic median definite hurdles in 1959, as well as These very first experimental models had been pre cast, concrete parabolic median hurdles, 26 inches high and 28 inches wide and weighed against 3000 pounds.
