PROBLEM TO BE SOLVED: To provide a collision risk determination device which can adequately determine the risk of collision. SOLUTION: An acquisition part 10 acquires traveling data on surrounding vehicles. An acquisition part 12 acquires data similar to the traveling data on the surrounding vehicles from its own sensor or the like. The acquisition parts 10 and 12 acquire the driving characteristics of each of the drivers. An acquisition part 14 acquires road environment data, such as link data, node data, signal data and so on, from the map data of its own vehicle. A forecasting part 16 inputs the road environment data, the traveling data on the surrounding vehicles, the traveling data on its own vehicle and the driver characteristics, determines the behavior of each vehicle from the environment of a road, traveling states of the surrounding vehicles and each of the driver characteristics, and forecasts a future traffic state. A determination part 18 determines that the case, in which the distance between its own vehicle and another vehicle ahead is a prescribed threshold value or less, is a dangerous case, based on the future behavior of each vehicle (traffic state) which is forecasted by the forecasting part 16. An outputting part 20 outputs the determination. COPYRIGHT: (C)2006,JPO&NCIPI
