ABSTRACT
The purpose of the test reported herein was to assess the performance of the Median Guardrail Transition to Median F-shape barrier, according to the safety performance evaluation guidelines included in the second addition of the American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH). The crash test was performed in accordance with MASH Test 3–21 (TL-3):
MASH Test 3-21: A 12270P vehicle weighing 5000 LBS impacting the longitudinal barrier transiton at 25° while travelling at 62 mi/h.
This report provides details on the design development using computer simulations, median guardrail transition to median f-shaped barrier test insulation, the crash test and results, and the performancea ssessment of the median guardrail transition to median f-shaped barrier for MASH Tl-3 evaluation criteria.
The median guardrail transition to median F- shape barrier did not meet the performance evaluation for MASH TL-3.
