| Outline of Final Research Achievements |
This research conducted a series of theoretical and empirical studies on the emergence of decentralized urban and transport systems through co-evolution of social environment and actions, such as the voluntary supply of transportation services in depopulated areas. As a result of research, we found that (1) social interaction models can be a strong basis for exploring the emergence of decentralized urban and transport systems. This is particularly true when the model is extended to deal with interactions that explicitly reflect decision making of multiple actors. On the other hand, the emergence of decentralized urban and transport systems may be influenced not only by actors’ decisions but also by the bundle of "constitutional choice rules", "collective choice rules", and "operational rules" surrounding them.

| Academic Significance and Societal Importance of the Research Achievements |
都市・交通システムは，公共主体が行う計画行為と，市場が価格を通じて行う需給調整に加え，住民や地域が自発的に行う種々のサービス供給に依存している．こういった自発的供給の重要性は，コミュニティのレジリエンス等の議論を通じて広く認識されつつあるものの，それを下支えする理論研究とその存在と影響を示す一連の実証分析が十分に行われてこなかった．このギャップを埋めるのが本研究の学術的・社会的意義と考える．
