Abstract:Roadway lane-reduction transitions have long been reported to be problematic for drivers. Whether this problem is the result of a lack of understanding of lane-reduction signing or lane markings, a simple failure to comply with such markings, or other unidentified factors is unknown. This study, completed in 2019, explored driver behavior when exposed to four warning signs, two advance warning signs, and two lane line transition markings. The warning signs included traditional and new designs. Some of the new designs have currently been adopted by State departments of transportation. This study quantified driver behavior by investigating when drivers recognized that the lane would end, prepared to change lanes, and executed a lane change. The inclusion of advance warning signs resulted in earlier recognition of lane termination. Dotted-with-solid-white lane line transition markings resulted in earlier lane changes.
