Shared e-mopeds and equity implications: Insights from trip-level data in Fukuoka, Japan

This study examines the role of shared e-mopeds in improving transport accessibility and equity in Fukuoka, Japan, particularly in comparison to public transit. Using monthly-level aggregated port-level trip data, we analyze overall travel patterns, first-mile trips to, and last-mile trips from train stations and city centers. Our findings show that shared e-mopeds reduce travel time and distance compared to buses and rail, with the most pronounced benefits in low-land-price areas where public transit access is limited. However, despite these advantages, high travel costs in low-land-price areas, especially for first-mile trips, pose a financial burden on users due to longer travel distances and time-based pricing structures. These results highlight the potential of shared e-mopeds as a flexible mobility solution, particularly in underserved regions, and emphasize the need for policy measures such as expanding port networks and introducing fare subsidies to enhance their role in fostering equitable urban mobility.
