CASE STUDIES OF WRONG-WAY ENTRIES AT HIGHWAY INTERCHANGES IN VIRGINIA

An evaluation of a 2-year survey of wrong-way driving led to on-site investigations of a number of intersections and interchanges. The investigations showed a consistent pattern in wrong-way entry incidents that related to road geometrics, markings, and signs. Based on the findings of the investigations, five case studies were developed to show the effects of these variables. This paper discusses the results of the survey, some case studies, and measures for preventing wrong-way entries at selected interchanges. Some of the recommendations made are as follows: Channelize the left lane of the exit ramp and remove the left end flare; investigate the effectiveness of stop lines, the continuation of pavement edge lines across exit ramps, and the use of continuous double yellow lines; through the use of signs, provide intersection geometry information for drivers entering a 4-lane divided highway; and provide additional pavement marking and spotlighting to supplement signs.
