This benefit summary describes the efficiency and security of an internet-based electronic supply chain manifest system (ECMS) against a traditional manual paper-based system. ECMS was designed to save time and money by automating the transfer of cargo information from one mode of transportation to another. The American Trucking Associations Foundation (ATAF) deployed the system at O’Hare and JFK International Airports, and the Federal Highway Administration (FHWA) monitored the performance of the system for 2.5 years. The project was carried out in three phases with the primary objective being to improve the efficiency of cargo data transfer between manufacturers, truckers, and airline carriers.
