This paper describes the safety effectiveness of replacing a two-way left-turn lane with a raised median on a high-volume, six-lane arterial in Atlanta. In the year after completion, the Memorial Drive median project prevented about 300 accidents and 150 injuries. There was a 37 percent reduction in total accident rate and a 48 percent drop in the injury rate. Left-turn accidents between intersections were virtually eliminated. Over the 4.34-mile section, a number of less-significant public-road intersections were not given median breaks. On similar retrofit projects, wehre narrow raised medians are used, all remaining median openings should be strongly considered for signalization. Also, adequately designed U-turn capability should be provided at each opening, if possible, with right-turn-on-red prohibition considered on cross-street approaches. Well designed, double left-turn lanes should be included where needed. A mountable curb allows the median to be driven on by emergency vehicles and reduces the possibility of an errant vehicle losing control upon striking it.
