Although demand-responsive transport (DRT) has been proposed as an innovative mobility solution to enhance accessibility in rural areas, its adoption and utilization remain low. To facilitate broader acceptance, it is essential to identify the factors influencing individuals’ willingness to use such services. This study examined preferences for DRT based on stated preference data collected from 610 respondents in a rural region of Japan. The analysis showed low willingness to use the service, with 75.4% of respondents indicating that they would not utilize it for any trip purpose, regardless of service attributes. To explicitly account for this non-compensatory behavior, an integrated probabilistic choice set and latent variable (IPCSLV) model was developed. Compared with traditional choice models, the IPCSLV model demonstrated a superior fit and yielded more interpretable results. The findings indicated that older adults aged ≥ 75 years, non-drivers, and individuals who were aware of the nearest bus stop were more likely to consider DRT as a transport alternative. Positive perceptions of DRT were also linked to higher levels of acceptance, with participation in the demonstration trial contributing to the development of these favorable views. Among those who considered DRT, service was most preferred for trips to the railway station, and cost emerged as the most influential service-related factor affecting usage. These insights support the design of tailored services that target the specific user groups identified in the analysis. While individuals with high car dependency were more likely to exclude DRT, offering free trial opportunities may encourage them to consider adopting DRT.

<p>Subjective evaluation of individuals is crucial for adopting new mobility services. This study aims to understand the acceptability of two newly emerged personal e-mobility services—shared e-motorcycle and e-scooter services―and the subjective evaluations underlying their acceptability. A questionnaire survey was administered across Japan in December 2023 to understand the factors underlying acceptability. The survey included questions about the acceptance of shared e-motorcycles and e-scooters and questions related to measuring subjective factors, trust, perceived usability, positive and negative perceptions, and positive and negative affect. An ordered probit model was used to identify factors influencing acceptability. The results showed that subjective factors, such as experience with similar existing services, trust in the new mobility service, perceived usability, system usability scale, and positive and negative perceptions of the new mobility service, significantly affected an individual’s acceptability. For instance, an individual’s experience with bicycle sharing increases their intention to use e-motorcycles and share scooters. In addition, individuals who trust mobility and sharing services are more likely to use shared personal e-mobility services. The use of shared e-motorcycles and e-scooters was significantly driven by perceived usability—related to easy access to shared mobility. Finally, positive perceptions of personal e-mobility sharing significantly increased acceptability, whereas negative perceptions had the opposite effect.</p>
