This discussion paper summarizes the literature relating to the use of medians on major roadways. The primary focus is on safety due to the sizable amount of literature in this area and the very limited number of studies relating to such topics as the effect on business, the effect on traffic operations and public attitudes toward medians. The summary includes data drawn from the significant, but limited number of studies, conducted in the 1950's and 1960's as well as from the relatively large body of research conducted in recent years. While there are a few before-and-after studies, most of the literature consists of comparisons of the average crash rates of roadways having different cross-sections.
