Document Type and Number:
WIPO Patent Application WO/2017/170144
Kind Code:
A1
Abstract:
Provided are: a movement guidance device which enables guidance information which will be required for future movement guidance to be preferentially retained; and a computer program. Specifically, movement guidance information 26 which is for guiding the movement of a moving body, and which is delivered from a server device 3, is used to guide the movement of the moving body, and the movement guidance information 26 delivered from the server device 3 is stored in a cache 47. The movement guidance information 26 stored in the cache 47 is partitioned in area block units of map information, and retention priority levels are set. The movement guidance information 26 for areas for which the retention priority level was set low, in the movement guidance information 26 stored in the cache 47, is more preferentially deleted from the cache 47 than that for areas for which the retention priority level was set high.
