Title: COLLISION PREDICTION SYSTEM, COLLISION PREDICTION DEVICE, COLLISION DETECTION METHOD, AND PROGRAM
Abstract:
With the purpose of obtaining a correct collision prediction result if a grade-separated crossing cannot be recognized from an image, a collision prediction device mounted on a mobile body detects a mark provided at a position on either an upper road or a lower road which is located at a lower position than the upper road, in the grade-separated crossing. The collision prediction device transmits information indicating that the mark has been detected, to another collision prediction device mounted on another mobile body other than the specific mobile body on which the collision prediction device is mounted. Also, the collision prediction device predicts a collision on the basis of whether or not the information indicating the detection of the mark has been transmitted from another collision prediction device, and whether or not the device itself has detected the mark.
