• Abstract:
  A detailed statistical analysis of Texas roadside barrier accidents in comparison with another state which uses the nationally accepted guard fence standard was conducted. Snagging on the unblocked out system used in Texas was not an obvious problem based on this data set, although vehicles under 2500 pounds in curb weight did have a 9 percent greater probability of rollover. The w-beam barrier redirects about 65 percent of the impacting vehicles and the expected increased severity with decreasing vehicle curb weight upon impact with a concrete safety shape could not be tested due to the very small number of concrete safety shape impacts in the Texas data set.
