Abstract
Regional public transport in mature society has been playing an important role of supporting civil life. However, citizen's mobility level has been decreased, because bus services in Japan have run on a self-paying basis, and the number of its passengers tend to be decreasing.
In this paper, we suggested the evaluation methods for regional public transport especially bus services considering on citizen's mobility level. In addition, we carried out some case studies in Japanese municipalities in order to make sure if we can apply quantified citizen's mobility level defined in this study to the regional public transport planning. In other words, we tried to be specified features of limited mobility groups and unprofitable bus routes which was essential in order to achieve a minimum level of citizen's mobility.
