- ItemIntegration of resilience and risk to natural hazards into transportation asset management of road networks: a systematic review(Taylor & Francis Ltd., 2023) Allen, Eduardo; Costello, Seosamh B.; Henning, Theunis F. P.; Chamorro Giné, Marcela Alondra; Echaveguren, TomásTransportation asset management is a systematic process for the operation, maintenance, and upgrade of physical transportation assets over their life cycle. Although transportation asset management has continued to evolve over the years, the integration of transportation resilience into the process is an ongoing challenge for transportation agencies. Given that natural hazard events can result in significant damage to assets as well as cascading effects on other critical networks that depend on transportation systems to operate, the importance of this challenge cannot be overstated. Consequently, this paper presents a systematic literature review on the integration of resilience and risk into transportation asset management, with a focus on road networks, in order to understand the current state of the art and practice and to identify the ongoing challenges in the field. The review specifically focuses on the integration guidelines adopted by different countries and departments of transportation, as well as the different consequence modeling approaches used, resilience metrics, and methods to integrate transportation resilience into transportation asset management. A number of research gaps in the current state of the art and practice are then highlighted, and potential future research directions are presented.

- ItemRisk Management of Rural Road Networks Exposed to Natural Hazards: Integrating Social Vulnerability and Critical Infrastructure Access in Decision Making(2025) Contreras Moya, Marta; Chamorro Giné, Marcela Alondra; Guerrero Mancilla, Nikole Fernanda; Martínez Reyes, Carolina del Pilar; Echaveguren, Tomás; Allen, Eduardo; Bronfman Cáceres, NicolásRoad networks play a crucial role in accessing, sourcing, and evacuating populations during extreme natural events. These issues are especially critical in rural settings, where redundancy of networks is uncommon and where the population may present significant social disparities. Traditional risk management systems have studied the risk of the road network from a physical perspective, where the probability of damage is estimated in terms of its fragility (vulnerability) and exposure given certain hazard intensity measures. However, the specialized literature increasingly suggests the development of more comprehensive risk management systems, where not only physical aspects associated with infrastructure are considered but also the social and economic characteristics of the beneficiary population. This study proposes a Vulnerability Access Index for road network decision-making that integrates social vulnerability of rural communities exposed to extreme natural events and their accessibility to nearby critical infrastructure. The proposed methodology considers three stages: Stage 1, Social Vulnerability Index based on socioeconomic variables, to which a principal component analysis is applied to identify the most determining dimensions of social vulnerability; Stage 2, Importance Index to evaluate access to critical infrastructure, and; Stage 3, Vulnerability Access Index, which is obtained as a combination of the indices estimated in the previous stages. A case study is presented in a highly exposed region to volcanic hazards in Chile. The proposed index identified links of the road network that require special attention as they provide access to highly vulnerable population and present critical access issues.
