Abstract
Working efficiency is improved without wasted activity of vehicles by enabling prompt change of a travel route at a time when it becomes necessary to change the travel route of a vehicle. A monitor station changes a worksite towards which a vehicle should travel from a worksite 60a to a worksite 60a′ on the basis of a result of monitoring current positions of a plurality of vehicles and current status of a plurality of worksites. At the same time, the monitor station provides data for the travel route from the current positions of the vehicles to the changed worksite 60a to the vehicles. Upon receiving the data for the travel route from the monitor station, the vehicles then travel along the travel route from their current positions to the changed worksite 60a′.
