THE CONCRRETE SAFETY SHAPE BARRIER AND SMALL CAR ROLLOVER

Although concrete safety shaped barriers are a valuable safety tool, a number of studies have been undertaken to determine the danger to vehicle occupants of small cars, especially those which weigh under 2,250 pounds. The Texas Transportation Institute conducted a study to determine the extent and severity of overturn collisions with these type barriers, identify the root causes of rollover of vheicles in impacts with these barriers, and identify potential countermeasures to reduce rollovers. Four data files were used by researchers along with a computer simulation and the HVOSM-RD2 program which was modified for use with rigid barrier impacts. The HVOSM could not provide valid data for very low angle impacts of 5 degrees or less. Injury and severity statistics as well as rollover versus nonrollover statistics are given. Simulations were also done on F-shape, constant sloped and vertical wall barriers in comparison with the concrete safety shaped barrier. These comparisons did not make any of the other barriers an overwhelming favorite over the concrete safety shaped barrier, thus further research is needed.
