• Abstract:
  When a roadway intersects a highway with ; restrictive features, such as a bridge rail, it becomes ; difficult to fit a guardrail with the proper length, ; transitions, and end treatment along the highway. ; Possible solutions include relocating the constraint ; blocking the placement of the guardrail or designing ; a short radius guardrail. ; Short radius guardrails typically present the most ; viable solution. However, no previously designed ; short radius guardrails meet National Cooperative ; Highway Research Program (NCHRP) Report 350 Test ; Level 3 (TL-3) guidelines. Crash-testing criteria have ; been updated by the American Association of State ; Highway and Transportation Officials Manual for ; Assessing Safety Hardware (MASH). MASH uses ; heavier test vehicles than NCHRP Report 350. ; Therefore, meeting new impact standards for short ; radius guardrails has become even more challenging
