Fifty accidents were analyzed. The primary data base consisted of Kentucky accident records for the years 1980-82. Results showed that the breakaway-cable-terminal end treatment performed properly in most accidents (72 percent). If trucks are excluded from the analysis, the BCT performed properly in 63 percent of the collisions. The median-breakaway-cable-terminal end treatment performed properly in 50 percent of the accidents. Problems related to stiffness of the end treatment are most apparent when impact angles are shallow. A recommendation was made to remove any existing MBCT designs from gore area locations and replace them with a crash cushion. A new turned-down end treatment design was proposed for consideration at median installations.
