Abstract
A turning value corrector corrects turning values contained in multiple pieces of travel history information. A reference turning value calculator uses multiple turning values that have been associated with the same calculation point to calculate a reference turning value. An anomalous travel location detector calculates the divergence from the reference turning value for each piece of travel history information subjected to detection of an anomalous travel location. Locations for which the deviation from the reference turning value is large are detected as anomalous travel locations.
