Depopulation and aging are currently problems in many regional cities in Japan. In these areas, it becomes difficult to
maintain public transport services and ensure mobility for residents. This leads to reduced communication among
residents and a lower quality of life. It is important to provide sustainable mobility for residents to avoid the collapse
of the community in these areas. To solve these local problems, the author’s group has developed low-speed electric
community buses (LSECBs) and researched their effects on social implementation. The LSECBs are electric vehicles
that can travel on public roads at speeds less than 20 km/h (5.56 m/s). The LSECBs were jointly developed with the
participation of local companies, local government, university, and residents. The LSECBs are suitable for short-
distance operations within small regional areas. LSECB can promote communication and strengthen bonds between
people, and also improve quality of life. This study examines the effectiveness of LSECBs in enhancing the
sustainability of local communities.
