我々は、仮想市場法を用い東京圏で市民が必要とする交通環境の障壁除去施策の内容とその必要技術量を貨幣尺度で客観的に計測した。筆者らは、東京圏の交通環境の特徴を適度に反映しつつも平均所得に差がある東京都国立市と神奈川県相模原市で社会調査を行なったが、ほとんどの施策で平均所得が高い国立市民の支払意思額が相模原市民の支払意思額より高く「応能負担」の優位性が実証された。 It is important to remove barriers in the transportation environment. However, engineering studies are inclined to focus on the developers 'financial restrictions and citizens' position. In addition, in many regional policy studies customer satisfaction is dealt with by a survey. Therefore the authors apply "CVM" to measure the amount of technique which citizens require in terms of money, taking the promotion of widespread normalization and the developers' financial limitations into account. As a result, the authors recognized that the larger the citizens' income is, the higher the citizens' "WTP" becomes for improving non-barrier transportation systems becomes. That is, the developers should collect the cost of establishing the non-barrier transportation system according to the scale of household economy.
