 This paper examines the potential of sleeping assets, neglected routes, idle real estate, and underutilized resources to provide solutions to the strain on urban resources. It suggests that cities should take advantage of these assets to reduce the pressure on existing infrastructure and improve efficiency. The paper also identifies seven key barriers to implementing sleeping assets, including political and legislative barriers. Finally, it offers advice on how to overcome these obstacles and make use of sleeping assets. This article was authored by Larissa Schachenhofer, Yvonne Kummer, and Patrick Hirsch.
