Many agencies discourage access within the functional area of a signalized intersection, as recommended in current access management guidelines, which also suggests that unsignalized median openings be bidirectional openings designed for only left turns from the roadway (and possibly U-turns). This report details transportation agency efforts to better quantify the operational and safety performance associated with unsignalized full median openings located near upstream and downstream traffic signals that have at least one turning bay.
