Abstract: A sinusoidal traffic line that has scalloped edges to form a sine wave that increases visibility under conditions of reduced visibility is formed of a pre-cut ribbon or applied traffic line material (e.g., sprayed thermoplastic material). The traffic lines have a wavy left edge and a wavy right edge. The edges are formed in a regular pattern, having a regular amplitude and wavelength relative to a directional vector along the axis of the traffic line. The patterns of the outer edges are arranged in an opposite arrangement such that they converge and diverge. The upper surface of the traffic line can be embossed by an embossed device so as to create a regular pattern and increase reflectivity.
