Transportation systems are vulnerable to natural and human-caused hazards, such as climate change, terrorism, economic and demographic changes, cyberattacks, and other events—all in the context of limited financial resources. These events and trends can result in unanticipated transportation system disruptions and increasing constraints on existing infrastructure, impeding access to reliable mobility for people and goods. Given the increasing risk, it is critical to design or modify transportation systems to be adaptive, investing in strategic resilience planning and implementation in advance of events (shocks or stressors).
While state departments of transportation (DOTs) understand the importance of incorporating resilience planning into transportation decision-making, the state of the practice varies. For example, studies from Oregon, Colorado, and Utah illustrate how corridor-based resilience planning provided direction to project design, continued operations, and maintenance. Other state DOTs, such as the Michigan DOT and Florida DOT, are examining how resilience concepts could be included in statewide transportation planning. A few others, such as Caltrans, are conducting resilience studies through their planning divisions.
Efforts to address strategies for improving resilience planning are increasing as documented in multiple NCHRP studies, such as NCHRP Project 20-117: Deploying Transportation Resilience Practices in State DOTs and NCHRP Synthesis 527: Resilience in Transportation Planning, Engineering, Management, Policy, and Administration. In addition, FHWA has sponsored efforts that examine the relationship between resilience and transportation planning, illustrating the importance of advancing the practice of integrated planning (FHWA Resilience Resources).
Guidelines are needed to help state DOTs and other transportation agencies integrate resilience concepts strategically and systematically into the transportation planning process.
The objective of this research is to develop a guidebook on how state DOTs and other transportation agencies can integrate resilience concepts into transportation planning efforts at all scales of application. |
