Elements of median design in relation to accident occurrence. Paper presented at the 52nd Annual Meeting of the Highway Research Board, Washington D.C., January 1973.

The findings of a study on accident histories as related to median widths, slopes, and configurations are reported. The authors conclude, that wider medians are safer medians, that raised medians have a number of undesirable characteristics, and that medians with irregular width should be designed only with adequate clear zones. Median shoulder requirements are also discussed. (See also B 2722 for preprint of paper).
