都市問題の根本的な解決のためには, 地域計画の概念にもとついて都市圏の将来の理想像を描き, それに接近するための総合的な再開発計画を通じて都市構造を望ましい姿に誘導するという施策が必要である。
そのための基礎的な分析を目的として, 都市近郊の発展と交通の関係を明らかにするために人口, 人口密度と都心への時間距離との関係について考察し, 都市交通手段, とくに高速鉄道網の整備条件が今後の近郊地域の人口, 人口密度におよぼす影響, ならびに各高速鉄道路線の将来の輸送需要を予測するための手法についてのべる。

In almost all cases, phenomena we usually treat accompany with them a property of random variation. At the same time a majority of them is possesed of a characteristic of continuity. A simple way of simulation of random phenomena frequently used is a method of random walk or more generally the Monte Carlo method. In order to fulfill the second characteristic of continuity, the author proposes a modified method of simulation consisting essentially of the weighted sum of several groups of random number series, each of which has the different time length of duration and the R.M.S. intensity. Practical procedures are described to put the technique into operation by a digital computer. Mathematical representations of the correlation and spectrum functions for the proposed model are derived.
Statistical analyses by the method of Tukey and Blackman of a thus composed random phenomenon are given to show the correctness and availability of the technique.
