40 Safety Analysis In this report, researchers documented the results of multiple analyses focused on developing an improved understanding of WWD crash characteristics on divided highways as well as wrong-way countermeasure effectiveness on divided highways and freeways. An in-depth safety analysis of wrongway crashes using a multistate dataset assessed the impact of median width and traffic control devices upon wrong-way crashes on high-speed divided highways.

41 – Wrong-way arrow markings for the through lanes on the divided highway, – Presence of a centerline in the median opening, and – Use of stop or yield lines when interior right-of-way treatments are provided. Separate analysis of WWD event data support the use of flashing red LEDs within the border of WRONG WAY signs at freeway exit ramps.
