Traffic Control Devices Pooled Fund Study: Signing for Intersection Geometrics That Require U-Turns

This research project aimed to explore and evaluate the effects of directional signing alternatives for intersections requiring U-turns on drivers’ comprehension of the signs, time required to comprehend each alternative, and preferences among the alternatives. The researchers used a combination of still images of signs and short computer animation video clips created using their driving simulator. In general, the guide and regulatory signs in the Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) provisions that were tested performed well for the minor leg approaches to intersections that require U-turns. For the major leg approaches, signs that contained the word “U-turn” or included a U-turn-shaped arrow produced more accurate and more confident responses.
