摘要

PROBLEM TO BE SOLVED: To provide a collision danger notification device capable of avoiding a collision between a moving body crossing a road and an approaching vehicle while avoiding an increase in load of communication and control due to unnecessary collision danger notification. A server (collision danger notification device), when detecting a moving body that is about to cross a road, travels along the road with information about the road, moving body information including a current moving body position and moving speed. The approaching vehicle moves by identifying the approaching vehicle approaching the crossing prediction area where the moving body is predicted to pass from the start of the crossing to the end of the crossing based on the current position of the vehicle and the vehicle information including the moving speed. Predicts whether the vehicle will collide or not, and notifies the danger of collision if the approaching vehicle is expected to collide with the moving body, and notifies the danger of collision if it is predicted that the approaching vehicle does not collide with the moving body. Control notifications not to. [Selection diagram] Figure 1
