“…The methodology presented here is generalizable to other similar contexts, which is a significant advantage and a relevant benefit for policy purposes. Future research could involve the use of optimization models to improve operational efficiency of the transport service ( Iliopoulou & Kepaptsoglou, 2019 ; Verma, Kumari, Tahlyan, & Hosapujari, 2017 ; Wei et al, 2017 ) or to tackle service and energy costs more specifically ( Batarce & Galilea, 2018 ; Brown, 2018 ; Cavallaro, Danielis, Nocera, & Rotaris, 2018 ; Tong, Hendrickson, Biehler, Jaramillo, & Seki, 2017 ). Future work could also examine additional customer-oriented smart services because interconnected transit solutions foster the possibility of offering further specific services to organizations and transit users ( Nocera, Fabio, & Cavallaro, 2020 ).…”
