A) This is a report related to the study of influential area of Rapid Transit Stations. Especially main emphasis is placed upon the trip generation's ratio of commuters within those influential area. B) The study area is put along a privately owned rapid transit line within Tokyo Metropolitan area. From this study we get such results as follows; 1) A borderline of station's influential are will be defined at the place where the ratio of cummulative commuter's distribution is to be reached to 90 per cent. 2) Firstly a ratio of commuter's trip to the total population within its area was examined, and the ratio of those trip to the total number of households was sought. A better result was gained from the latter analysis, because the fittness of correlation coefficient of the latter study was higher. 3) The station's influential area should be divided to two parts, the first of which must be called the main station's influential area where most parts of its commuters will be included. 4) In order to estimate the number of commuters within residential district along its Rapid Transit Line, we get those formulas. T_1=0.324x T_2=1.068y T_3=-0.1495x+1.145y where : T=number of commuters x=population size y=number of households
