SINUOUS TRAFFIC LINE
First Claim
1. A system of sinusoidal traffic lines comprising:
- applied traffic lines that are arranged to have a wavy left edge and a corresponding wavy right edge so as to create a sinusoidal line in a directional vector along the axis of the traffic, a pattern of the wavy left edge being identical and corresponding to a pattern of the wavy right edge.

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. In another embodiment, 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.

12. A method for application of sinusoidal traffic lines comprising the steps of:
-
preparing a mixture of traffic line material in an applicator device; pre-heating the mixture of traffic line material to a first temperature and mixing the material with a quantity of glass beads; pressurizing the preheated traffic line material to a first pressure such that the preheated traffic line material enters and flows through one or more feed lines to an applicator head of the applicator device that is provided with a nozzle; moving the applicator head laterally at a regular rate to create a sinusoidal of a first amplitude; and moving the applicator device along a directional axis of travel such that the lateral movement of the applicator head moving laterally on a device that is moving along the axis of directional travel creates a sinusoidal line of a first wavelength.
