Identification and prioritization of multidimensional resilience factors for incorporation in coastal state transportation infrastructure planning

Effective integration of resilience in transportation planning requires the identification and prioritization of multifaceted resilience factors. In this study, an extensive review of the academic literature and state planning documents was conducted to identify measurable technical, socioeconomic, and environmental resilience factors for wind- and water-related hazards. Transportation experts across the state of Florida were then surveyed to gain insight into the significance, relevance, and comparability of the identified factors. By statistically analyzing the survey responses, the resilience factors were prioritized to allow transportation agencies to optimize their resource allocation toward critical resilience aspects and effectively improve resilience within their limited budgets. Overall, the age of infrastructure, emergency response, and network exposure were identified as the top technical, socioeconomic, and environmental factors, respectively. This study also presents five key recommendations, informed by insights from a workshop involving transportation practitioners throughout Florida, to overcome current barriers to incorporating resilience in transportation planning. These recommendations cover the topics of proper communication, funding availability and public engagement, plans alignment, data collection processes, and the development of comprehensive resilience assessment frameworks. This study contributes to the body of knowledge and state of practice by providing valuable insights and actionable strategies to facilitate the practical integration of resilience considerations in transportation planning, ultimately assisting in the overall resilience enhancement of transportation systems.
