Automated, secure inter authority settlement method and system for electronic toll collection

摘要

Electronic toll collection will eventually become standardized on the nation's toll roads making possible non-stop toll payments to many different toll Authorities from a single in-vehicle-device. Such a development should go hand-in-hand with electronic inter Authority settlements from prepaid accounts held by any one Authority, paying any other Authority for a vehicle's use of its facilities. This invention describes a method, and a system, that conducts automated, inter Authority settlements from prepaid accounts in a manner suited to a large number of participating, autonomous Authorities also including the ability to detect and pinpoint fraud affecting each Authority's cash flow anywhere in the greater system.
