Emerging technologies are redefining the transport sector in its entirety, bringing both opportunities and challenges for sustainability. This chapter explores the role of these technologies on sustainable transportation. This research seeks to provide an answer by relating how emerging technologies influence transport for sustainability, evaluating the challenges in adopting emerging technologies for sustainable transport, the policy and regulatory factors in the support of emerging technologies for sustainable transport, how big data and the IoT are helping develop intelligent transport systems, and analyzing the social effects of emerging technologies in sustainable transport. This study seeks to provide a thorough and multidimensional approach to the subject, deriving theoretical and practical knowledge on the challenges and opportunities of sustainable transport through a combination of a critical review of the literature and content analysis.
