A Survey of Smart Parking Solutions T. Lin, H. Rivano, and F. Le Mouël Smart parking is a major and costly issue in the largest cities. This survey covers the parking literature over the period 2000–2016 by focusing on research approaches, technological evolutions, and engineering developments of smart parking solutions. It introduces the smart parking ecosystem and proposes a comprehensive and thoughtful classification by identifying different functionalities and problematic interests. Three macrothemes are elaborated: information collection, system deployment, and service dissemination. In each macrotheme, the main methodologies used in existing works are synthesized to bring out their common goals and visions. Authors give engineering insights to highlight current smart parking challenges and open issues and, finally, extend the scope and provide recommendations for future research on Smart Cities and the Internet architecture.
