This study focuses on the social value of local public transportation, defined as its spillover effects across various sectors. We attempt to build a model for logically and quantitatively understanding the social value. Specifically, based on findings from previous studies, the effects of local public transportation on sectors such as healthcare and welfare, community development, commerce and tourism, industry and the regional economy, childcare and education, and traffic safety, environment, and infrastructure management were organized into a logic model. Furthermore, issues related to implementing public transportation policies that consider social value were identified through interviews with local governments, and actions to address these challenges were proposed.
