1. A turning probability prediction apparatus, comprising:
a map data storage device configured to store map data including road data, the road data including links representing a prestored road and nodes representing intersections of the pre-stored road; a non-transitory storage medium configured to store turning information on an intersection-by-intersection basis of the prestored road, the turning information comprising probabilities of making respective turns at an at least one intermediate intersection of the prestored road; a controller, with a processor, configured to update the map data stored in the map data storage device to include a new road based on update data received from a center and to determine whether the new road is added to the map data; a route search device that, when the controller determines that the new road is added to the map data, retrieves a route comprising the prestored road and the new road, the new road including a first intersection at a first end and a second intersection at a second end, each of the first intersection and the second intersection intersecting the prestored road; and a prediction device that predicts a probability of turning at the first end of the new road, based on the probabilities of making respective turns at the at least one intermediate intersection specified by the turning information stored in the non-transitory storage medium, wherein the at least one intermediate intersection is different than the first intersection and the second intersection of the new road, and is arranged in the route comprising the prestored road retrieved by the route search device, and the controller, with the processor, is configured to store the predicted probabilities in a database. |
