Abstract: The present invention relates to a secure method and enabling processes to: (1) through the use of personal nomadic communicators (PNCs) to automatically declare passenger occupancy in transport conveyances including but not limited to road vehicles, aircraft, trains, marine vessels, (2) monitor and assess the pattern of physical movements of passenger PNCs prior to, during, and after their use of such transport conveyances, (3) verify and record passenger occupancy based on such assessments and any suspicious patterns suggesting fraudulent declarations through the improper use and placement of PNCs not belonging to passengers, and (4) transfer occupancy data to management systems which utilise passenger occupancy as a factor in decision making including but not limited to determining occupancy related entitlements to the operators/owners/managers of transport conveyances.
