  • Travel information recording system, method, and program
    Patent number: 9846044
    Abstract: A travel information recording system for associating travel information on a vehicle obtained immediately after travel through a branch location with an appropriate road segment includes: travel segment specifying unit for specifying a travel segment that is a road segment in which a vehicle is traveling; and travel information recorder for recording travel information on the vehicle obtained during travel in the travel segment in association with the travel segment in a storage medium. In the case where there occurs a segment variation in which the travel segment is varied from one of several road segments branched off from a branch location, the travel information recorder acquires the travel information to be recorded in association with a post-variation segment, which is the travel segment after the segment variation, on the basis of the travel information obtained before the segment variation.
