Outline of Final Research Achievements	While the use of public transportation is declining in local cities and cabs are more efficient than buses, it is difficult to secure drivers and sales offices are withdrawing from the market. There is demand for door-to-door transportation for the aging population, but high fares are a bottleneck. In order to sustain local cab services, it is necessary to improve operating efficiency and lower prices. In this study, GPS data from cab companies in Nagaoka City were used to examine the possibility of improving operational efficiency and reducing costs through advance reservations. As a result, it was confirmed that when advance reservations are made 100% of the time, costs are reduced by about 1/3, and by about half with joint taxi dispatch. In addition, a questionnaire survey confirmed that discounting user fees increased demand and increased profits through operational efficiency.

Academic Significance and Societal Importance of the Research Achievements	地方都市の郊外部においては，タクシードライバーの確保は難しく，タクシー営業所等の撤退が進みつつあり，住民の足の確保が大きな問題となっていが，地方タクシーを持続させるには，実車時間の割合が低いといわれているタクシー運行効率の向上と，値下げによる利用者の増加が必要である．長岡市内のタクシーのGPSデータを使用し，タクシー会社が共同で配車するという前提で，どの程度費用が削減されるかを検討した．結果として，事前予約が100％という非常に理想的な状態では費用が約1/3削減され，さらに共同配車事業が導入された場合は費用が約半分に削減される可能性を確認し，事業の継続性の可能性を示すことができた．
