    摘要: The present invention provides a system capable of generating a highly accurate, highly up-to-date map database by increasing the efficiency of operations to generate and update the map database.
    The system includes a feature database 2 for storing feature information F relating to features existing on a road and on the periphery of the road, each feature being associated with a unique identification symbol IDf, the feature information including disposition information F1 expressing a spatial disposition of each feature independently of a road network R including a plurality of nodes N having position information and a link L connecting two of the nodes N, form information F2 expressing a form of each feature, accuracy information F3a expressing an accuracy of the information, and acquisition timing information F3b expressing an acquisition timing of the information; output means 8 for outputting the feature information F stored in the feature database 2; and input means 5 for inputting map information M constituting the map database 3, which is generated on the basis of the feature information F output by the output means 8.

    摘要: A travel time data processor extracts a link that is present in the neighborhood of a target link, as a reference link. The travel time data processor selects an identical time zone of the reference link that is identical with the time zone of the target link in which the number of sample data is less than a reference number, and searches for another time zone having similar statistical data to that of the selected time zone. The travel time data processor adds the number of sample data in a time zone of the target link corresponding to the searched another time zone of the reference link to the number of sample data in the time zone of the target link that is equal to or less than the reference number, and generates statistical data from the summed-up sample data.
