PROBLEM TO BE SOLVED: To provide a technique which estimates an origin and destination (OD) with high granularity in a wide area by using landmark information comparatively easy to acquire in a wide area to generalize probe data in a limited region.SOLUTION: An origin and destination of an unknown route is predicted by a computer. First, input of second landmark information including types and positions of known landmarks included in a second area is accepted, and a second feature vector at each point included in the second area is generated on the basis of the second landmark information, and the probability that each point included in the second area is the origin and destination is predicted on the basis of a prediction model obtained on the basis of first landmark information including types and positions of known landmarks included in a first area and information on known origins and destinations included in the first area, and the second feature vector. The prediction model is preliminarily learnt. |
