To start support control with a margin under a small processing load.SOLUTION: A prediction unit 62 of a traffic safety support system includes: a movement state information acquisition section 620 that acquires movement state information of a prediction target; a surrounding state information acquisition section 621 that acquires surrounding state information of surrounding traffic participants; a driver state information acquisition section 623 that acquires driver state information of a driver of the prediction target; a first movement state prediction section 624 that predicts a first predicted movement state of the prediction target on the basis of the movement state information; a second movement state prediction section 625 that predicts a second predicted movement state of the prediction target on the basis of the driver state information; a collision risk calculation section 626 that calculates a first collision risk value for the first predicted movement state and a second collision risk value for the second predicted movement state; and a support control unit 65 that executes support control fro the prediction target in a case where at least any one of the first and second collision risk values is greater than a collision determination threshold value.SELECTED DRAWING: Figure 3
