Outline of Final Research Achievements

We analyzed the influence of public transportation services on visitors’ activity spaces in the central area of Kobe City, using GPS trajectory data. Public transportation services contributed to expand visitors’ activity spaces in the central area and loop bus service was particularly effective to the elderly. We developed pedestrian activity-travel behavior models considering alteration of visitors’ initial activity plans. The proposed models consist of choice of the number of activity locations initially planned, choice regarding whether continuing activity, activity type choice, activity location choice and activity duration choice. The results showed that it is possible to reproduce visitors’ activity-travel behavior with good accuracy using the models, and the increase in the attractiveness of city center can encourage of alteration of visitors’ activity plans, causing the number of activity locations and activity duration in the city center.

Academic Significance and Societal Importance of the Research Achievements

都心の賑わいを創出するためには，来街者の回遊行動を促進させるような施策が求められる．本研究で構築した回遊行動モデルは，来街者が回遊中にふらっと新たな活動を追加する行動を再現できる．これによって，都心空間の整備による来街者の回遊行動の誘発度を定量的に評価できる．また，個々人の選択行動をモデル化しているため，若者，高齢者や子育て世代などの様々な属性に適応した土地利用・交通施策パッケージも評価可能である．
