1. The population of Tokyo increases in an arithmetic series, while the traffic volume in a geometrical series. The discrepancy between them is getting more and more remarkable especially after the war (Fig. 1).
2. The areal unbalance of, traffic volume. between the city center and the circumference of the city, and the unbalance between the rush hours and rush-off hours are recognized.
3. Such unbalance of traffic volume is caused by the city center. After the war, the city center has made a rapid growth by its cubicalization and the modernization of its function (Table 1). It is a problem that. almost all passengers direct of the only terminal, the city center.
4. After the war new reenforced concrete buildings have been promptly constructed in Tokyo (Fig. 4), and 46% of the total number of the buildings and 63% of the total floor space are concentrated in the city center (Chiyo da-ku, Ghuu-ku, Minato-ku).
5. The business center in the city center is located in Marunouchi, the area between the Tokyo Station and the Palace. Table 2 shows the total floor space of all the buildings in Marunouchi, the total number of employees at work in Marunouchi (a) and that of visitors (b). The of (a) and (b) makes the total population in all the buildings, namely the actual day-pop-dlation of the area. Such population as this is to be the. potential traffic population which should be carefully considered for the establishment of a transportation plan.
6. Between the traffic volume in demand and the capacity of the transportation facilities a remarkable discrepancy can be seen (Fig. 6). Under the present circumstances, the cubicalization of transportation facilities is far more difficult than that of buildings. In order to get rid of this discrepancy, there will be no way but the restriction of excessive growth of the city center.
7. The control of the areal unbalance must be settled first for the purpose of taking off the unbalance of the traffic volume in the city. The dispersion of city center, the bringing up of satellite city centers is the key point for it. The writer has an opinion that the bringing up of satellite city centers should take precedence of the -establishment of satellite residence cities. The rationalization of city center is the essential for the, solution of the city problem.
