Abstract
In this research, we first categorized transport surveys of passenger flow in Japan and found out their situations. Large-scale transport statistic surveys have been conducted and they provide information for planning or just for statistics purposes. Next, we analyze current situations of urban transport using the results from Nationwide PT Survey, and found the following. a) The number of trips has declined in Japanese cities as the society ages. The vehicle ownership and driver’s license holders increased further. Thus, automobile use has increased overall. This could exacerbate environmental burdens in the future. b) Compared to younger age groups, the elderly use car less often and makes fewer trips. As aging progresses, the number of elderly without mobility is anticipated to increase. c) In Japanese cities, modal split varies by the size of urban area and population density. Lately, with the declining trend of population density, it may contribute significant increase in car use.
