Abstract
A pavement marking tape has raised, irregular polygonal relief features with retroreflective elements covering a portion of the surface of the tape. The form of the relief features minimizes shadowing effects. Raised relief features are shaped to increase the visible number of vertical faces and edges of the relief features, which are the most reflective structures, and are oriented toward incident light from an approaching observer to maximize retroreflectivity.
