The collection target data represents a feature in the road section on a map to be generated or updated. The apparatus also includes a processor configured to notify the vehicle of the type information with the communication device, and update the type information for each of the road sections, in the case that collection of the collection target data of the type designated for the road section has been completed, so as to stop collection of the collection target data in the road section.

Abstract: An apparatus for collecting data for map generation includes a processor configured to determine whether the current state of a vehicle is suitable for collection of collection target data to be used for generating or updating a map, based on suitability data received from the vehicle with a communication device. The suitability data indicates suitability of the vehicle or surroundings thereof for the collection. The processor is also configured to instruct, with the communication device, the vehicle to collect the collection target data when determining that the current state of the vehicle is suitable for the collection.

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.
