User’s Activities when Using Mobility as a Service- Results of the Smart Mobility Challenge Project 2020 and 2021

摘要

Mobility as a Service (MaaS) is expected to spread globally and in Japan asa solution for social issues related to transportation. Researchers haveconducted MaaS trials in several cities. However, only a few trials havereached full-scale practical use. Therefore, it is essential to clarify issuessuch as the business model and user acceptability and seek solutions tosocial problems rather than simply conducting trials. This paper describesthe introduction of a MaaS project supported by the Japanese governmentknown as the “Smart Mobility Challenge” project, conducted in 2020 and2021. We employed five themes necessary for social implementation fromthe first trial of this MaaS project. As a consortium, we also promotedregional demonstrations by soliciting regional applications based on thesefive themes. In addition, we conducted fundamental research using datafrom the MaaS projects to clarify local transportation issues in detail,collect residents’ mobile behavior data, and assess the project's effects onthe participant’s happiness. We employed the life-space assessment methodto investigate the spread of the residents’ behavioral life-space resultingfrom using mobility services. The spread of the life-space mobility beforeand after using mobility services confirmed an expansion of the life-spacebecause of specific services. Moreover, we conducted questionnairesurveys and clarified the relationships between life-space assessment,human characteristics, and subjective happiness using path analysis. Wealso conducted a persona-based approach in addition to objective datacollection using GPS and wearable monitors and a web-based questionnaire.We found differences between the actual participants and participantsassumed by local governments. We conducted interviews and developedtips for improving mobility service. We propose that qualitative data helpclarify the image of mobility services that meet the residents’ needs.
