Building success: Top-level governance strategies for transport megaprojects

Abstract

Transport megaprojects often face underperformance, prompting policymakers to seek effective governance strategies. Existing governance theories fall short in addressing the complexities of these projects and lack consensus on an effective framework. This study, rooted in Transaction Cost Economics (TCE), examines top-level governance in transport megaprojects, emphasising the importance of government involvement and structured governance models throughout the project lifecycle. Through descriptive case studies, we develop a theoretical framework that transitions from stewardship to hybrid and agency models, detailing the dynamic governmentality, governance structures and mechanisms required at each phase. Our findings highlight the critical role of top-level governance in simplifying decision-making and optimising resource integration. This framework broadens the scope of governance to include planning stages, enhancing strategic alignment, resource allocation, and stakeholder collaboration. The study provides valuable insights into the current and future state of top-level governance in transport megaprojects, positioning it as a key domain in “governance as practice.”
