A collision risk calculation device (1) may calculate a collision risk that matches an on-site feeling by calculating, by using track data of each of a first vessel and a second vessel, a base risk value related to a collision between the first vessel and the second vessel at each time point by a predetermined method, specifying a time range before a maximum base risk value from the base risk values, extracting, from the track data, an action pattern of one or both of the first vessel and the second vessel in the time range, calculating a degree of the action pattern of one or both of the first vessel and the second vessel on the basis of the action pattern, and correcting the base risk value on the basis of the degree of the action pattern and a weight set for each action pattern.
