Abstract:
A method for detecting and monitoring noncompliant transportation of a material, the method comprising the steps of:(a) providing a detection and monitoring network whereby multiple ports-of-entry are each equipped with a detection system that is in communication with a central computer; (b) using the detection systems to detect levels of the material in vehicles passing through each of the ports-of-entry, and when the detected material levels exceed a predetermined threshold, issuing an alarm to indicate a noncompliant load; (c) associating the levels of material detected for each vehicle with the respective vehicle; and (d) uploading the vehicle material levels detected at each port-of-entry to the central computer for monitoring and review, such that if the vehicle passes through a first port-of-entry in a first state without triggering the alarm, and then enters a second state and triggers the alarm, the central computer can be accessed to determine that the vehicle picked up the noncompliant load in the first state.
