A collection request inputted at a consignor destination system is recorded on
an electronic tag attached to freight and sent to a collection management system
so as to be received. During collection of freight, information concerning collection
is recorded on the electronic tag by means of a terminal unit and the collection
information is sent to the collection management system. Anin-base station freight
information management system informs a freight information overall management
system of the collection information and information concerning freight passing
through the base station. The freight information overall management system acquires
a transport history of the freight on the basis of the information sent from the
in-base station freight information management system, calculates a delivery schedule
of the freight and informs it to each in-base station freight information management system.
