• Abstract:
  Cable barrier systems designed to be used in median ditches have been traditionally full-scale crash tested placed either ; within 4 ft from the slope break point (SBP) of a 4H:1V front slope or near the bottom of the ditch. Recently, there has been ; some discussion about proposing specific standard test conditions for cable barrier systems which are designed to be placed ; in a median ditch. ; The objective of this research was to propose a matrix of critical tests for cable barriers placed in median V-ditches. Critical ; tests were proposed based on the identification of those locations where the potential for override/underride is more likely, ; as indicated by an analysis of the simulated bumper trajectory of small cars, passenger sedans, and pickup trucks when ; trespassing a median V-ditch. The bumper trajectories as well as the vehicle kinematics were obtained using LS-DYNA ; computer simulations considering different ditch widths and slopes. Results from previous full-scale crash tests of cable ; systems placed in V-ditches were also considered in the assessment of the test matrices.
