1. An alert output apparatus comprising:
at least one memory; and
at least one processor communicably coupled to the memory,
wherein the processor is configured to:
receive, from each of a plurality of in-vehicle units mounted individually in a plurality of vehicles, a travel behavior data indicating a travel behavior of the vehicle in which each of the in-vehicle units is mounted, to record the travel behavior data in a travel history database;
read a travel behavior data indicating a travel behavior of each of the vehicles to detect an avoidance action arising in each of the vehicles based on the read travel behavior data;
extract, from the avoidance actions of the vehicles, peripheral avoidance actions that arise within a predetermined position range within a predetermined time range based on an occurrence position and an occurrence point of time of each of the avoidance actions of the vehicles;
map the extracted peripheral avoidance actions on a road map to extract a group of avoidance actions that arise on an identical road based on the peripheral avoidance actions mapped on the road map as a related avoidance action group being a plurality of avoidance actions arising due to an identical object at different positions at different points of times in different target vehicles included in the plurality of vehicles; and
record information on a position change of the identical object that serves as a cause of the extracted related avoidance action group, as an alert target data indicating a position change of an alert target object in an alert target database.
