GLARE BARRIER CUTS ACCIDENT RATES

Today's glare barrier is the end product of years of development which has now produced a design of galvanized steel, slit into diamond-shaped patterns angled at 22 degrees to the plane of the original sheet. When viewed from the angle of the approaching motorist the mesh appears to be a solid sheet that totally blocks out headlight glare from a vehicle in the opposite lane. Installation is now a simplified sequence of five steps, using a two-man crew and, once installed, the barrier provides years of maintenance- free service. The real test is its ability to bring down the rate of accidents. On a horizontal curve of I-71 in Columbus, Ohio, where 13 accidents had occurred, only five were reported during the same period after glare barrier installation. On I-76 near Philadelphia, night accidents dropped 23 percent after installation on a test stretch by the Penn DOT Bureau of Traffic Engineering.
