Location Selection And Maintenance Of Highway Guardrails And Median Barriers

Guardrail and median barrier design information is presented which will permit the safest highways consistent with current state-of-the-art barrier technology. Since guardrail and median barrier installations are hazardous in themselves, emphasis is placed on reducing the number of installations to those which can be clearly justified. The design procedure presented involves two steps: (1) determination of points and length of need for the installation, and (2) selection and layout of appropriate guardrail or median barrier system.
