To provide a method by which an index that assists in analyzing train delays by utilizing actual operation data and is useful for investigating a counter measure against the delays, is quantitatively calculated.SOLUTION: A device for calculating an influence degree of delays in this invention extracts delay events causing delays from events of arrival and departure, based on actual operation data, devises a delay propagating network indicating connections between delay events by relating delay events with each other which satisfy a prescribed causal relationship condition determined as a causal relation condition of delays, and calculates an influence degree of delays given to other events of arrival and departure by the noteworthy delay events, based on the number of delay events connected in a direction of causal relation from noteworthy delay events that are arbitrary delay events in the delay propagating network.SELECTED DRAWING: Figure 1

    【課題】運行実績データを利用した列車遅延の分析の一助となる、遅延対策の検討に有用な指標を定量的に算出する技術を提案すること。【解決手段】運行実績データに基づき、着発事象のうちから遅延が生じた遅延事象を抽出し、遅延に関する因果関係の条件として定められた所定の因果関係条件を満たす遅延事象同士を関連付けることで遅延事象間の繋がりを表す遅延伝搬ネットワークを策定し、遅延伝搬ネットワークにおいて任意の遅延事象である着目遅延事象から因果関係の方向に繋がる遅延事象の数に基づいて、当該着目遅延事象が他の着発事象に与える遅延の影響度を算出する。【選択図】図1
