The ageing of the world's population is a growing phenomenon. Numerous studies have shown that mobility is a key factor for active and healthy ageing. In this context, demand-responsive transport (DRT) plays a key role, as it offers better accessibility and inclusiveness to the over-65s compared to traditional public transport, which is often under-used by the elderly. The aim of this article is to compare two DRT services for older people operating in distinct geographical and cultural contexts , such as Genoa (Italy) and Toyoake City (Japan). Two questionnaires were administered to the users in order to identify the factors influencing the increase in DRT usage. It is then possible to suggest to decision makers what improvements should be made to increase DRT in both areas. The results show that availability of DRT and accessibility to DRT stops are key factors in both contexts.
