The objectives of this research are to (1) determine the type(s), number, and location(s) of traffic control devices required on freeway and expressway ramps, cross streets, frontage roads, intersection approaches, and emergency cross-overs in order to improve safety and deter wrong-way movements; (2) evaluate the impact of varying median widths on wrong-way movement signing and marking requirements on low- and high-speed rural and urban divided highways; (3) identify inconsistencies in the Control Devises (MUTCD) pertaining to median widths used to determine whether medians are treated as one or two intersections for traffic control purposes; and (4) propose edits and revisions of relevant sections of the MUTCD.
