PREDICTED TRAVELING TIME DATABASE, PREDICTED ARRIVAL TIME CALCULATING UNIT, ROUTE SEARCH DEVICE, AND NAVIGATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a predicted traveling time database capable of acquiring a predicted arrival time whose precision does not greatly vary according to time conditions to be applied.;SOLUTION: A predicted traveling time database is stored in a storage unit 14 and allows information to be processed by an accessing computer 11. The database includes: an inter-second-area predicted traveling time database unit that defines information on an inter-second-area predicted traveling time that represents a predicted traveling time of a moving body from each second area to another second area within each first area obtained by statistical traffic information in terms of a time condition in correspondence to the time condition; and an inter-first-area predicted traveling time database unit that defines an inter-first-area predicted traveling time information that represents a predicted traveling time of the moving body from each first area to another first area obtained using statistical traffic information in terms of a time condition in correspondence to the time condition.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
