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.

Claims

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;

describing a contiguous assembly of three parallel line portions with a first portion having a concentration of glass beads per gallon of paint that is different from the concentration of glass beads per gallon of paint of a second portion;

the second portion being the outermost portions of the traffic line.

2. The system as set forth in claim 1 wherein the each of the second portions is a side margin with a width of one quarter inch.

3. The system as set forth in claim 1 wherein concentration of glass beads in the paint within the second portions is four times that of the first portion.

4. The system as set forth in claim 2 wherein the increased concentration of glass beads in the second portion is at a ratio of twenty-four pounds of glass beads per gallon of paint.

5. The system as set forth in claim 4 wherein the increased concentration of glass beads in the second portion increases the visibility of the edges of the traffic lines.

6. The system as set forth in claim 1 wherein the sinusoidal traffic line increases visibility of the traffic lines in periods of reduced visibility.

7. The system as set forth in claim 1 wherein each of the second portions has a different width relative to the other.
