Car Sharers’ Interest in Integrated Multimodal Mobility Platforms: A Diffusion of Innovations Perspective

Abstract

Integrated multimodal mobility (IMM) platforms are being discussed as a promising solution to facilitate the transition to sustainable transport in both urban and rural areas. The idea behind such platforms is to provide a one-stop-shop offering information, booking and payment options for multiple means of transport. The aim of this paper, based on diffusion of innovations theory (DoI), is to investigate the interest in IMM platforms, as well as the factors in potential user groups that may influence the intention to use them. A sample of 711 car-sharing users responded to an online questionnaire containing items on DoI variables, as well as on the specific requirements concerning IMM platforms. The results show that few members of car-sharing schemes have used IMM platforms before, but that the interest in them is generally high. Perceived advantage and personal compatibility show the strongest associations with the intention to adopt IMM platforms followed by innovativeness, observability of use (social visibility of the innovation) and perceived technology security. Additionally, a target group was defined for the efficient and effective promotion of IMM platforms in an early market phase. Measures to promote IMM platforms were suggested based on this group’s perceptions and their specific requirements.
