Title:
ANOMALOUS TRAVEL LOCATION DETECTION DEVICE AND ANOMALOUS TRAVEL LOCATION DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/111344
Kind Code:
A1
Abstract:
An anomalous travel location detection device that detects anomalous travel locations. An anomalous travel location is a location where anomalous travel in the width direction of the road occurs. A history information acquisition unit obtains, from a vehicle, travel history information that includes a turning value. The turning value indicates a physical amount related to the position of the vehicle and the turning of the vehicle. A turning value correction unit corrects the turning values contained in multiple items of the travel history information. The turning values are corrected to turning values associated with each instance of a predetermined calculation subject location. A standard turning value calculation unit uses multiple turning values that have been associated with the same calculation subject location to calculate a standard turning value. The standard turning value is an average turning value. An anomalous travel location detection unit calculates the deviation from the standard turning value for travel history information for which detection of an anomalous travel location is to be performed. Locations for which the deviation from the standard turning value is large are detected as anomalous travel locations.
