Abstract:

The objective of this research was to design a simple low-cost guardrail terminal at Manual for Assessing Safety Hardware (MASH) Test Level 2 (TL-2) (44 mi/h) that assumed use of a current generic MGS W-beam guardrail, which is the most widely used guardrail in the country. The terminal design was tested and evaluated according to the safety-performance evaluation guidelines included in the second edition of MASH (1). The crash tests were performed in accordance with MASH TL-2. This report provides details on the development and simulations of different designs for the TL-2 W-beam end terminal, the crash tests and results, and the performance assessment of the TL-2 W-beam end terminal for MASH TL-2 gating terminal evaluation criteria. The final TL-2 W-beam end terminal design met the performance criteria for MASH Tests 2-35, 2-30, 2-31, and 2-37b for gating terminals.
