Abstract: A road surface abnormality detection apparatus includes a data acquisition unit, a prediction unit, and an abnormality detection unit. The data acquisition unit acquires road surface observation data obtained by observing a road surface in a chronological order. The prediction unit predicts road surface data at a first timing from a plurality of road surface observation data at a plurality of respective timings earlier than the first timing by using a trained model generated in advance through machine learning. The abnormality detection unit detects, when a difference between road surface observation data at the first timing and the predicted road surface data at the first timing is equal to or larger than a predetermined threshold, an abnormality of the road surface.
