Modeling of interaction of population movement, regional economic and transportation based on stochastic user equilibrium network analysis.

本研究旨在建立人口迁移模型，明确人口迁移的原因。人口迁移有两种类型：一种是城区间的迁移，另一种是非城区间的迁移。在本研究中，笔者构建了城市区位变动的模型。城市区域最初是以通勤标准来设定的，首先建立了一个没有明确处理其原因的模型。该模型采用了四步流量估计法。以长度表示的流动阻力表现为两个城市之间的长度，无论它们是否属于同一个县，从每个城市到东京的长度。在第二种模型中，明确地处理了上班、上学、结婚、更迭和其他。选择每个原因的系数，并对第一个模型使用相同的长度阻力。将搬家总量表示为每个原因搬家次数的总和，建立了一个较好的城市区位变动搬家模型，明确处理了搬家的原因，体现了搬家的性质。

This study aims to build the model of population moving explicitly dealing with the reason for moving. The population moving has two types : one is city-area-change moving and another is non-city-area-change moving. The author build the model of city-area-change moving in this study. City area is originally set by standard of commuting.A model which is NOT explicitly deal with the reason is built at first. Four step flow estimation method is applied to this model. The resistance of movement by length is represented by the length between two cities, whether they belong to the same prefecture, the length from each city to Tokyo.Getting work, going up to school, marrying, changing office and the other is explicitly dealt with in second model. The factor of each reason is selected and the same resistance by length is used with the first model. The total amount of moving is expressed to the sum of the number of moving by each reason.As the result, we build a good model of city-area-change moving explicitly dealing with the reason of moving express the character of moving.
