Introduction
摘要
Even before the COVID-19 pandemic, the transport sector—particularly urban mobility—was facing some complicated challenges: constantly increasing traffic, limited green spaces available to citizens and the massive use of private vehicles over public and sustainable modes of transport. The advent of aforementioned contagion has, in fact, prompted local administrations to rethink their urban public transport system. While the negative externalities of this contingency are well known, during this historical period, many growth opportunities have also arisen that policymakers and institutions should seize.
