Outline of Final Research Achievements	Various transportation systems have been developed in recent years. In this study, combinations of transportation modes are analyzed using a multi-agent system. The study focused on the southeastern part of Osaka City, where BRT and on-demand buses are operated. It was found that the share of walking among the access transportation modes is high, and the introduction of BRT increases walking, which is effective in promoting health. In addition, as a measure to promote the use of BRT, the development of bicycle parking stations and share cycle ports near BRT stops are examined, and found that while the provision of bicycle parking stations leads to increased use of BRT, the provision of share cycle ports leads to increased use of bicycles to railway stations. Furthermore, in the southern part of the BRT route, even if bicycle parking stations are provided, there is little hope of increasing BRT usage.
Free Research Field	都市交通システム
Academic Significance and Societal Importance of the Research Achievements	交通機関の多様化が進むとともに、公共交通は利用者数の減少・採算性に加え、ドライバー不足の問題も深刻になり、減便などが行われている。適切な交通機関の整備水準は、都市構造・人口構成などに依存するため、都市に合わせた適切な交通機関の組み合わせの検討が必要である。また、たとえばシェアサイクルはポートに自転車がなければ利用できないなど、交通機関の選択行動は複雑になっている。本研究では、マルチエージェントモデルを用いて相互作用などを考慮したモデル化を行ったことに意義がある。結果として、分析対象地域では、シェアサイクルの整備はBRT利用が減少する可能性があることが明らかとなった。
