Abstract
Currently it is necessary for the local government to develop local transport plan. In early stage of planning, the potential ridership of public transport service is needed to assess the sustainability and the adequateness of the service level. For the practitioners in the local governments, simple methods based on four arithmetic operations to estimate the potential ridership are helpful. In this study, the unit value of the potential ridership for is estimated. The estimated value is tested with many cities and municipalities so as to verify its usefulness and validness.
