ABSTRACT:
A pre-fabricated ferromagnetic loop having a footprint characterized by a continuous wire shaped according to a predetermined planar pattern. In some embodiments, the predetermined planar pattern can be multiple contiguous polygons within a larger footprint used for establishing a sensor for the detection of moving vehicles. The footprint may include one of a triangle, a square, a rectangle, a rhombus, a parallelogram, an ellipse, or a circle, and/or other shapes or configurations. Similarly, each of the multiple contiguous polygons may include one of a triangle, a square, a rectangle, a rhombus, a parallelogram, and/or other shapes or configurations. A loop sensor housing is arranged to enclose a continuous loop sensor wire configured in the predetermined planar pattern. The prefabricated loop sensor is inserted in a groove web pre-cut in a receiving medium to match the predetermined planar pattern.
