A comparison of the safety potential of the raised versus depressed median design. Paper prepared for the 53rd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1974

This study examines the safety benefits of the raised median design as compared to the depressed design for interstate highway medians having an 84 foot design width. The effect of each median design on the frequency and severity of median-involved accidents, on the path of the encroaching vehicle, and the vehicle's tendency to overturn was studied.
