Description

The research project provided a low-cost option for guardrail terminals that fit within the low-speed context of many roadways that the Federal Land Management Agency (FLMA) owns and operates. The research project developed a W-beam guardrail terminal for use on low-speed roadways (45 MPH and under). The guardrail terminal is a simple design, composed of readily available, off-the-shelf components. The design is visually unobtrusive and compatible with aesthetic coatings. To minimize environmental and right-of-way impacts, the W-beam guardrail terminal is as short as possible and does not require excessive offset from the roadway centerline.

The research used advanced computer simulation methodology to analyze the design concept before it conducted a series of full-scale crash tests of the design concepts using the critical test conditions.
