Electric Vehicles and Urban Tourism in Smart Cities: A Bibliometric Review of Sustainable Mobility Trends and Infrastructure Development

This study presents a bibliometric review of global research trends on electric vehicles (EVs) and urban tourism within the context of smart cities, emphasizing the economic and policy dimensions of sustainable mobility and infrastructure investment. Drawing from 593 publications indexed in the Web of Science from 2005 to April 2025, the analysis explores document types, leading research areas, alignment with Sustainable Development Goals (SDGs), influential authors, and highly cited works. A keyword co-occurrence analysis reveals six major thematic clusters, highlighting key topics such as EV adoption behavior, renewable energy policy, wireless charging technology, and semiconductor innovation. Engineering and physics emerged as dominant research areas, with SDG 7 (Affordable and Clean Energy) and SDG 11 (Sustainable Cities and Communities) most frequently represented. The findings underline a growing interdisciplinary effort to integrate EV technologies with urban tourism through smart, carbon-neutral transport systems, supported by policy frameworks, green investment incentives, and digital infrastructure. This review identifies research gaps and opportunities to advance energy-efficient, economically viable, and tourism-oriented mobility solutions in smart cities by mapping the current knowledge landscape.
