A Study on the Industrial and Spatial Change of the Tokyo Metropolitan Area Through the Shift in Business Trips

Recently, the industrial and spatial structure of the Tokyo Metropolitan Region has considerably changed with the shift of business centers and the change in individual work pattern. This study aims at clarifying the relationship between the macroscopic structure of the region and its effect on the characteristics of travel behavior of individual workers, such as frequency, trip pattern and the dependence on car use. Based on the analysis of time-series data from the Person Trip Survey, it is confirmed that: a) the amount of business trips generated by administrative workers and professional workers has increased mainly in the suburban core areas, b) the modal share of private car use has increased in most areas and c) an annular trip network between the core areas has been promoted.
