N2  - A cost-effectiveness analysis was used to study safety-treatment options for embankments and culverts on resurfacing, restoration, and rehabilitation (3R) projects. An examination of the need for cable and W-beam guardrails to shield traffic from roadside embankments and roadside culverts, respectively, was made. Average embankment and culvert accident severities were estimated using Highway Safety Information System data from Utah and Michigan. Average accident severities were calibrated through computer simulations of ran-off-road accidents. Simplified design charts were developed to allow highway engineers to quickly determine the need for cable guardrail on 3R projects.<p /> <p>Language: en</p>
