<p>The present invention aims at obtaining a correct collision prediction result even if a grade separated crossing cannot be recognized based on images. A collision prediction device provided in a moving object detects a mark placed on either an overpass road or on an underpass road at the grade separated crossing. Then, the collision prediction device transmits information that denotes that the mark has been detected to a collision prediction device provided in a moving object other than a concerned moving object that is provided with its collision prediction device. In addition, the collision prediction device predicts a collision depending on whether the information that denotes that the mark has been detected has been transmitted from the other collision prediction device and whether its collision prediction device has detected the mark.</p> |
