1. An unmanned vehicle management system comprising:
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, the plurality of unmanned vehicles including a first unmanned vehicle and a second unmanned vehicle; and
a guidance command unit that, when occurrence of a traffic congestion is predicted, outputs a first guidance command such that the second unmanned vehicle that causes the traffic congestion enters a side path branching from the travel path;
wherein a first course data generation unit generates first course data indicating a travel condition of the first unmanned vehicle, wherein a second course data generation unit generates second course data indicating a travel condition of the second unmanned vehicle, and wherein the second course data includes a travel course indicating a target travel route of the second unmanned vehicle, and the travel course is set on each of the travel path and the side path.
