  The objective of this study is to propose a system-level framework with
quantitative measures to assess the resilience of road networks. The framework
proposed in this paper can help transportation agencies incorporate resilience
considerations into project development proactively and to understand the
resilience performance of current road networks effectively. This study
identified and implemented four quantitative metrics to classify the
criticality of road segments based on critical dimensions of road network
resilience, and two integrated metrics were proposed to combine all metrics to
show the overall resilience performance of road segments. A case study was
conducted on the Texas road networks to demonstrate the effectiveness of
implementing this framework in a practical scenario. Since the data used in
this study is available to other states and countries, the framework presented
in this study can be adopted by other transportation agencies across the globe
for regional transportation resilience assessments.
