INFORMATION GENERATION DEVICE

An information generation device generating a test case being a simulation model for reproducing a road traffic condition in an area on a road including a target point, the information generation device including: a first storage unit that stores a plurality of pieces of moving-object information being information regarding a moving object existing in the area detected by a sensor provided on a roadside; a determination unit that determines whether or not an incident in which the moving object existing in the area shows a behavior that leads to occurrence of an accident has occurred, on the basis of the plurality of pieces of moving-object information; an extraction unit that extracts, as target information, moving-object information in a target period being a predetermined time period including a time point at which the incident occurred, from the plurality of pieces of moving-object information; and a generation unit that generates the test case upon occurrence of the incident on the basis of the target information.
