A comparison of the safety potential of the raised versus depressed median design. Paper presented at the 53rd Annual Meeting of the Highway Research Board, Washington, January 1974.

The safety benefits of raised medians versus depressed medians in similar sections of Interstate highways are studied. The depressed design offered more opportunity for operators to regain control and return to their roadway than did the raised design, and that both designs were comparable in relation to vehicle roll-over, severity of accidents, and primary path of the vehicle. A discussion is added.
