Abstract
A passive elongated flexible roadway marking device attaches and conforms to a curved roadway median. The device includes an integrally formed plastic extruded spline and a protrusion having a D-shaped profile. Notches with stress relief vertices are provided in a flange of the spline to facilitate bending. Attachment holes are provided in each flange of the spline, in an alternating arrangement. Spaced apart retro-reflective tape strips are applied to the curved outer surface of the protrusion. A pressure sensitive adhesive on the bottom of the spline facilitate installation. A coupling connects several units.
