“…Although relatively new, there is already a growing body of literature covering various aspects of MaaS. The majority of MaaS literature focuses on assessing user's attitudes (Ho et al, 2019;Matyas, 2020;Alonso-González et al, 2020;Fioreze et al, 2019;Tsouros et al, 2021), willingness to adopt (Hensher et al, 2021;Caiati et al, 2019;Hörcher and Graham, 2020;Fioreze et al, 2019), and willingness to pay (Polydoropoulou et al, 2020a;Liljamo et al, 2020) for MaaS, whereas several studies concentrate on developing and assessing MaaS business models (Polydoropoulou et al, 2020b;Eckhardt et al, 2018;Aapaoja et al, 2017) and mobility service bundles (Sarasini et al, 2017;Aapaoja et al, 2017;Wong and Hensher, 2020;Reck et al, 2020;Polydoropoulou et al, 2020b), as well as policy aspects (Pagoni et al, 2021;Sakai, 2019;Jittrapirom et al, 2020;Jittrapirom et al, 2018;Li and Voege, 2017). Most of the above literature has considered MaaS in an urban environment including only land transport alternatives.…”
