(Urban Traffic)


    Concentration of the population to large cities is still continuing, although a trend of slowdown has been observed recently.
    In the large cities, a doughnut phenomenon of the distribution of population has been noticeable, with the midtown area having an increasing number of offices and the suburban area having a rapidly increasing population.
    As the result, the passenger transport in each of the three large urban areas is continuing to increase as shown in Fig. 2-1-3. By the transport means, the railway transport is increasing upon the increasing trend of the subway and commercial railway transport, while the transport by means of bus and taxi is in a decreasing trend. Noteworthy is the slowdown of the growth of the transport by private automobiles which showed a rapid growth in the latter half of 1960s.
    Now looking the cargo transport in the three large urban areas (Fig. 2-1-4), it had continued to increase until the latter half of 1960s at a rate well exceeding the growth of passenger transport, but recently it has been tending to top out. In 1974, it showed a substantial decrease, and the decline of the private trucks was particularly noted.
