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.

Abstract: The Wrong Way Detection System includes detection stations deployed at each egress point along a tollway in addition to various locations along the tollway's mainline. The detection hardware communicates preferably via fiber optic network to a customized software platform housed at a centrally located Incident Management Center (IMC) of the system, where each site is monitored 24/7 in real time for wrong way vehicles. Once a vehicle is detected, operators at the IMC are able to immediately dispatch law enforcement officers and monitor the vehicle's whereabouts via CCTV cameras.

Abstract: A system for automatic collection of tolls includes an in-vehicle toll processor having memory for storing a toll-money-available quantity purchased by the user, and a toll-facility-identification site that transmits a toll-facility-identifier signal indicating the identity of the upcoming toll facility. As the vehicle approaches the identification site, the in-vehicle processor receives the identifier signal and calculates the toll to be debited. When the vehicle passes through the toll facility, the in-vehicle processor transmits its identity, its net balance and the toll, which it debits from an account balance. The in-vehicle processor may increment a low balance, in which case it transmits information which is relayed to a central system for billing. Various means for shutting down delinquent in-vehicle components or identifying offender vehicles are described.
