1. An operation management apparatus of autonomous travel vehicles, which manages operations of a plurality of vehicles which autonomously travel on a circuit, the operation management apparatus comprising:
an operation schedule provider that provides a normal operation schedule, in which an arrival target time and a departure target time to and from each of a plurality of stops provided on the circuit are determined, to each of a plurality of operating vehicles which are autonomously traveling on the circuit;
an introduction judgment unit that judges whether or not an additional vehicle is to be introduced to the circuit based on a boarding demand on the circuit; and
a schedule changer that changes an operation schedule to be provided to each of the plurality of operating vehicles from the normal operation schedule when the introduction judgment unit decides introduction of the additional vehicle, wherein
the schedule changer can execute, as a schedule change process for changing the normal operation schedule:
an advancing change process in which a predetermined reference vehicle among the plurality of operating vehicles is set as a leading vehicle, and the departure target time of each of the operating vehicles which follow the reference vehicle is advanced from the departure target time determined based on the normal operation schedule so that an inter-vehicle space between a last operating vehicle among the operating vehicles following the reference vehicle and the reference vehicle on a next lap is enlarged for the additional vehicle;
a delay change process in which the departure target time of each of the operating vehicles which follow the reference vehicle is delayed from the departure target time determined based on the normal operation schedule so that an inter-vehicle space between the reference vehicle and an operating vehicle following the reference vehicle as a next vehicle is enlarged for the additional vehicle; and
a cut-in change process in which the plurality of operating vehicles are divided into an advanced vehicle line group for which the departure target time is advanced from the departure target time determined based on the normal operation schedule, and a delayed vehicle line group for which the departure target time is delayed from the departure target time determined based on the normal operation schedule, and an inter-vehicle space between the advanced vehicle line group and the delayed vehicle line group is enlarged for the additional vehicle, and
the schedule changer executes one of the advancing change process, the delay change process, or the cut-in change process based on the boarding demand.
