To enable systems to adapt to changing future conditions, ensuring adaptive capacity in resilience planning is critical. This paper presents an approach to evaluate the long-term benefits of adaptive resilience in infrastructure systems under future uncertainty. The methodology uses long timeframe assessment methods based on NPV and approaches to quantifying different levels of uncertainty along with multi-criteria assessment methods. The approach is demonstrated using three case studies, where investments have focused on different aspects of adaptive resilience in various infrastructure systems. The results demonstrate the increasing benefits of adaptive strategies over time with ongoing learning and the evolving nature of resilience needs. The presented approach can be used by decision-makers in multiple infrastructure sectors. A flexible approach to evaluate the long-term benefits of building adaptive capacity to enhance resilience, this methodology can be a useful tool for practitioners and policymakers to present a business case for long-term adaptive resilience investments..

A critical component of transportation asset management, asset valuation has been applied historically largely to provide condition-based value assessments of transportation infrastructure. There are emerging opportunities for innovations in asset valuation methodology with applications in the MAP-21/FAST performance-based era, and the Fourth Industrial Revolution (4IR). Opportunities exist to incorporate a wider range of value factors to capture multiple objectives in planning, design, and rehabilitation, such as safety, mobility, economic advancement, resilience, sustainability, and equity, to reflect the growing importance of intangible assets, as well as consider more explicitly value-adding technologies in this era of smarter infrastructure and rapid technological change. The paper first examines existing methods in transportation asset valuation practice and trends in asset valuation thinking through a literature review on asset valuation methodology with transportation applications. It then outlines innovation pathways and future research directions in asset valuation that can enhance existing capabilities to capture an expanding notion of transportation infrastructure value in the 21st century. For transportation professionals with continuing interest in valuation approaches to enhance asset management, this paper offers a catalog for identifying appropriate valuation approaches. For researchers and practitioners interested in pursuing innovations to secure increasingly smart, effective, and efficient transportation systems, the paper outlines innovation pathways and research directions enabled by growing computing power and data collection capabilities in the 4IR.

Incorporating adaptive resilience as a core value of transportation systems will equip transportation agencies to better address the increasing pace of future changes—both in climate and transportation system performance demands. Quantifiable measures are instrumental in incorporating adaptive resilience in agency organizational frameworks. This paper presents a dashboard tool that evaluates the maturity of adaptive resilience capabilities of a transportation agency, using an Adaptive Resilience (AR) Capability Maturity Model. A demonstrative example is presented to show the potential application of the dashboard tool and its implications for transportation system resilience planning. The example shows how the tool can facilitate identification of adaptive resilience capabilities that are at low maturity and thus may need prioritization for future resilience investments, and capabilities that are at a high maturity level and thus can be leveraged to enhance the lower-level capabilities. The AR performance dashboard tool may be used by transportation agencies to communicate their adaptive resilience efforts and maturity to stakeholders. It can also be used by practitioners to streamline and prioritize process improvements in adaptive resilience efforts.
