Claim 4:
5. A non-transitory computer-readable storage medium storing a program for calculating a dangerous spot and time that causes at least one computer to execute a process, the process comprising:
detecting a first avoidance action of a first mobile body and a second avoidance action of a second mobile body by determining whether a mobile body closest to the second mobile body at a time point at which the second avoidance action is detected is the first mobile body of which the first avoidance action is detected based on locus data when the first mobile body and the second mobile body belong to a certain area, the first avoidance action and the second avoidance action being an action for avoiding a possibility of a collision detected by an intersection of the first mobile body and a second mobile body;
calculating an evaluation value that indicates a possibility of a third avoidance action by a third mobile body under an influence of the first avoidance action based on a speed and an orientation of the third mobile body when that the mobile body closest to the second mobile body at the time point is the first mobile body is determined, the evaluation value including information that indicates whether loci of the first mobile body and the second mobile body are in a crossing relationship; and
calculating, based on the evaluation value, a collision risk in the certain area.
