Abstract
Recently, demand responsive bus attracts attention because of the merit of flexibility on operation. In order to clarify usefulness of demand responsive bus in suburbs, this study calculates the optimal operation minimizing the social cost, which consists of operation cost and user disutility. In this study, two rules of reservation for demand responsive bus are compared. One is on-spot reservation at bus stop just before using the bus, the other is previous reservation system. In numerical example, even though operation cost for the former rule became less, it gain larger social cost, became of large user cost due to large uncertainty of bus operation.
