UNMANNED VEHICLE MANAGEMENT SYSTEM AND UNMANNED VEHICLE MANAGEMENT METHOD

An unmanned vehicle management system includes: a traffic congestion prediction unit that predicts occurrence of a traffic congestion from travel situations of a plurality of unmanned vehicles traveling on a travel path at a work site; and a guidance command unit that, when occurrence of a traffic congestion is predicted, outputs a first guidance command so that an unmanned vehicle that causes the traffic congestion enters a side path branching from the travel path.
