Transportation infrastructure resilience and safety under climate risks: A global bibliometric and thematic analysis (1995–2025)

• A 30-year global synthesis of transportation infrastructure resilience is presented. • Four core domains and their temporal evolution are identified. • Gaps in governance, interdisciplinarity, and sustainability integration are revealed. • Policy directions to strengthen safety and climate resilience are proposed. • A framework for strengthening disaster risk reduction through interdependence and governance is proposed. In the context of intensifying climate risks and rapid urbanization, maintaining the safety and resilience of transport infrastructure has become a central challenge for sustainable mobility systems. Although research on transport infrastructure resilience (TIR) has expanded rapidly, it remains conceptually fragmented and insufficiently linked to broader environmental and policy agendas. This study provides a systematic and quantitative overview of global TIR research from 1995 to 2025, based on more than 2,000 peer-reviewed publications. Through bibliometric and content analyses, four major research domains are identified: climate adaptation and resilience planning, risk and vulnerability assessment, infrastructure performance and safety enhancement, and governance mechanisms for resilience management. The evolution of TIR scholarship is examined across three developmental phases, revealing a gradual transition from technical assessments toward integrated frameworks that combine safety, sustainability, and digital innovation. Persistent gaps are observed in institutional coordination, cross-system collaboration, and proactive adaptation strategies. Policy implications are outlined with emphasis on nature-based solutions, multi-hazard risk management, and long-term resilience planning. The findings contribute to a more coherent understanding of TIR and offer evidence-based insights for building safer, climate-adaptive, and inclusive transport systems. Taken together, these results provide an evidence-based overview that supports both scholarly positioning and practice-oriented agenda setting for climate adaptive and safety-oriented transport infrastructure resilience.
