内容記述 | 関東大地震時の状況や,現在の複雑な都市機構に過密人口を有する東京の状況から,来るべき大地震には,群集事故が多発するであろうと予想する。今日までに発生した群集事故の概観から,極めて高密度な群集塊の生因と,将棋倒しの力学的機構を明らかにする必要が生じ,それらのモデルを提案した。提案された第1のモデルは,群集が流出入する空間の面積,出入口の幅,および流出入量で群集密度の時間変化を表現している。第2の将棋倒しモデルによる計算に従えば,群集列における人間の間隔が60cmあれば,将棋倒しは生起しない。後ろから人が倒れ込んできた侍,先頭の人が支えられる人数は,せいぜい平地で7人,階段では4人であることがわかった。 | |||||

内容記述 | In the event of a strong earthquake in a large city like Tokyo,it is possible to predict that overcrowded conditions would cause heavy loss of life and personal injuries at places where crowds would stampede to escape the devastated area. In the present paper two mathematical models are proposed in relation to crowd flows. One of the models enadles us to know the temporal change in numer of people in an area where crowds are coming and going. Therefore,by means of this model,it is possible to obtain numerical solutions of,for example,the maximum possible inflow of persons per unit of time short of overcrowded conditions into a given area or the minimum effective width of an entrance through which flow a given in-flow of people would pass. According to the results of calculations provided by another proposed model for the successive toppling of people,it became known that the maximum number of persons whom one person could support without falling down himself,might be less than 7 on a flat surface and 4 on stairs. | |||||
