PROBLEM TO BE SOLVED: To provide a vehicle information recording system and a vehicle information recording program capable of associating vehicle information with any of a plurality of road sections even when the road sections similar in shape are present.SOLUTION: A vehicle information recording system comprises: a first recording unit 21a recording vehicle information during a high self-confidence-degree period which is a period in which a self-confidence degree of a current position is equal to or higher than a predetermined criterion in map matching and a road section where the current position is present in the high self-confidence-degree period so as to associate the vehicle information with the road section; a second recording unit 21b recording vehicle information in a low self-confidence-degree period which is a period in which the self-confidence degree is lower than the predetermined criterion; a candidate-section acquisition unit 21d acquiring candidate sections for a road section where the vehicle has traveled in the low self-confidence-degree period; and a third recording unit 21c identifying the road section where the vehicle has traveled in the low self-confidence-degree period from among the plurality of candidate sections, and recording the identified road section and the vehicle information in the low self-confidence-degree period so as to associate the identified road section with the vehicle information.SELECTED DRAWING: Figure 1

    【課題】形状が類似している複数の道路区間が存在しても、いずれかの道路区間に車両情報を対応付ける車両情報記録システム及びプログラムを提供する。【解決手段】マップマッチングにおける現在位置の自信度が所定基準以上の期間である高自信度期間中における車両情報と、高自信度期間において現在位置が存在していた道路区間とを応付けて記録する第1記録部21aと、自信度が所定基準未満の期間である低自信度期間中における車両情報を記録する第2記録部21bと、低自信度期間から高自信度期間に転じた時点において現在位置が存在する道路区間に基づいて、低自信度期間において車両が走行していた道路区間の候補区間を取得する候補区間取得部21dと、複数の候補区間のなかから低自信度期間において車両が走行していた道路区間を特定し、特定した道路区間と、低自信度期間中における車両情報とを対応付けて記録する第3記録部21cと、を備える。【選択図】図1
