• Abstract:
  Posted speed limits on Texas roadways have increased in recent years. Texas now has many miles of roadways posted at speeds of 75 mph and above. Barrier systems (e.g., guard fence, median barriers, and bridge rails) are currently tested and evaluated at a design impact speed of 62 mph. The performance limits of existing barriers are not known. Some barrier systems may have little or no factor of safety for accommodating more severe impacts beyond their design condition. The objectives of this project included determining appropriate impact conditions for roadways with posted speed limits of 75 mph and above, and exploring the capability of existing or modified barriers to accommodate these impact conditions.
