Abstract:
PROBLEM TO BE SOLVED: To provide a re-retrieval system and re-retrieval program that, upon re-retrieval, can prevent drivers from travelling a non-prioritized guidance road such as a narrow street road not suitable for travelling, for example, the non-prioritized guidance road including a road where vehicles are hard to travel, a risky road with a little traffic of the vehicle, or the like.SOLUTION: A re-retrieval system is the re-retrieval system that re-retrieves a travelling route of a retrieval object vehicle, and the re-retrieval system comprises: an initial retrieval unit 7a that retrieves the travelling route of the retrieval object vehicle passing only a priority guide road; a travelling history DB 8b that stores a travelling history of a collection object vehicle; a determination unit 7c that determines whether a re-retrieval timing of the travelling route of the retrieval object vehicle arrives; and a re-retrieval unit 7d that, when it is determined in the determination unit 7c that the re-retrieval timing arrives, re-retrieves the travelling route of the retrieval object vehicle on the basis of the travelling history stored in the travelling history DB 8b, and including the travelling history of a non-priority guide road by the collection object vehicle.SELECTED DRAWING: Figure 1
