A fleet management server is connected to onboard terminal equipments mounted on plural haulage vehicles. The server includes an operation mode determination unit and operation mode switching unit. The determination unit determines whether or not an operation mode, in which segment setting processing is performed to set travel-permitted segments for the vehicles, respectively, needs switching between a bidirectional mode and a push mode. In the bidirectional mode, the processing is performed to send response information upon reception of request information from each onboard terminal equipment. In the push mode, a travel-permitted segment setting unit, without reception of such request information, performs the processing for one of the vehicles to set a new travel-permitted segment, and produces and transmits travel permission information indicating the new travel-permitted segment. The switching unit performs switching processing of the operation mode according to the results of the determination.
