ROUTE SEARCH DEVICE, ROUTE SEARCH SYSTEM, AND SIGNAL STOP TIME COMPENSATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To search a route while stop time at signal intersections is considered sufficiently.SOLUTION: A server 3 compensates for stop time information on signal intersections for which stop time is insufficiently collected and the stop time information is not created since probe cars do not actually pass through the signal intersections or the number of probe cars passing through the signal intersections is relatively small, on the basis of stop time information on the other signal intersections for which the stop time information is created since the number of probe cars actually passing through the signal intersections is relatively large, and transmits traffic information containing the stop time information to a navigation device 4. The navigation device 4 searches a route from a departure to a destination using the traffic information received from the server 3.
