INACCESSIBLE ROAD SECTION ESTIMATION SYSTEM AND INACCESSIBLE ROAD SECTION ESTIMATION PROGRAM

摘要

Inaccessible road section estimation systems and programs extract regional road sections. Each of the regional road sections is a road section in a target region, and the target region is an area where a factor causing a road section to become inaccessible has occurred. The systems and programs estimate, as an inaccessible road section, a road section around which a mobile unit has detoured after occurrence of the factor, among the regional road sections.
