PROBLEM TO BE SOLVED: To appropriately complement travel time pertaining to missing when some of past travel time is missing.SOLUTION: A computer program according to one embodiment of the present invention causes a computer to function as a travel time complementation device, the computer program causing the computer to function as a data processing unit for executing an accumulation process of accumulating travel time at each time of day that proceeds every control cycle in a road section in a travel time database, and a complementation process which, when some of the accumulated travel time is missing, extracts a transition pattern of past travel time similar to a transition pattern to be complemented that includes a travel time before and after the missing time, and determines travel time at a time of day sandwiched between the extracted past transition patterns as travel time at the missing time of day.SELECTED DRAWING: Figure 7

    【課題】 過去の旅行時間の一部に欠測がある場合に、欠測に係る旅行時間を適切に補完する。【解決手段】 本発明の一態様に係るコンピュータプログラムは、旅行時間の補完装置としてコンピュータを機能させるためのコンピュータプログラムであって、前記コンピュータを、道路区間における制御周期ごとに進行する各時刻の旅行時間を、旅行時間データベースに蓄積する蓄積処理と、蓄積された旅行時間に欠測がある場合に、欠測時刻の前後の旅行時間を含む補完対象推移パターンと類似する過去の旅行時間の推移パターンを抽出し、抽出した過去の推移パターンに挟まれる時刻の旅行時間を、欠測時刻の旅行時間とする補完処理と、を実行する、データ処理部として機能させる。【選択図】 図7
