Abstract:
[Problem] To provide a collision alert device capable of generating display data which indicates the risk of collision between mobile bodies more appropriately. [Solution] A navigation assistance device 1 comprises a vessel data acquisition part 11, an other ship risk evaluation part 21, and a display data generation part 61. The vessel data acquisition part 11 acquires information relating to the positions and speeds of other ships. Using the information obtained by the vessel data acquisition part 11, the other ship risk evaluation part 21 calculates collision risk values indicating the risk that the other ships may collide with other vessels in the future. The display data generation part 61 generates display data which shows those other ships for which the calculated collision risk values indicate a prescribed risk or greater distinguishably from the rest of the other ships.
