Outline of Final Research Achievements	The Tokyo metropolitan area has developed rapidly after 70 years after the war, 50 years after the Tokyo Olympics, and a period of high economic growth. Major changes are expected in the future, such as various transportation infrastructure developments and the hosting of the Tokyo Olympics. In this study, the Tokyo Metropolitan Area, which has developed rapidly since the postwar period, was examined for future policy by empirical analysis using time series data and simulation analysis. Specifically, travel behavior characteristic analysis based on time-series PT survey data and a new web survey data were conducted to grasp changes in lifestyles of elderly people, women, young people, etc. In addition, an activity-based model was built using PT data, and prediction simulations based on future scenarios were performed.

Academic Significance and Societal Importance of the Research Achievements	長期間蓄積された時系列のPT調査による大規模データを活用し、過去から現在に至る交通行動の変化を分析したうえで、多様に変化するライフスタイルの変化をモデルに反映した研究は国内外においても先駆的な試みであり、その成果の学術的意義は大きい。また、過去から現在に至る交通行動の変化を踏まえたうえで、今後大きく変貌することが予想される東京都市圏における政策提案を科学的・実証的に行うことは、土木分野に限らず、社会・経済、都市、保健・福祉等、数多くの分野に知見を与え、その成果の社会的意義は大きい。
