Weather-related natural disasters are becoming an increasingly serious problem in the United States. As cities worldwide facing the growing risk of disaster, it is important to have measurable steps that can be taken to attempt to prevent and mitigate natural disasters. This report identifies the increasing severity of natural disasters and the role transportation systems play. It explores how transportation systems can be designed to help cities be more disaster resilient and mitigate future disasters. It does this by exploring transportation-specific disaster resiliency and mitigation strategies and identifying small-to-large-scale projects that cities can implement. The report selects best practices from the literature and provides a list and description of recommended strategies. This report concludes by providing funding mechanisms by which cities can implement projects
This Texas Department of Transportation (TxDOT) implementation project involved the development of workshop material aimed at disseminating research findings and training participants in hands-on use of the MS Excel-based calculator [sustainability enhancement tool (SET)] through a series of workshops in Fiscal Years 2009 and 2010. The specific project tasks were: Task 1 - Development of Draft Workshop Materials; Task 2 - Perform Workshop Walkthrough; Task 3 - Conduct Regional Workshops; Task 4 - Develop Final Workshop Materials; Task 5 - Update the Analysis Tool; Task 6 - Develop District-MPO-Local Agency Consortium Implementation Plan; and Task 7 - Develop Plan to Integrate into TxDOT Practice. The work done on these tasks is discussed in subsequent sections of this report. Chapter 2 describes the development of workshop materials, Chapter 3 summarizes the workshops conducted, Chapter 4 discusses local agency implementation and plans to integrate into TxDOT practice, and Chapter 5 provides the conclusion and future research. Overall, the research dealt with developing performance measures for sustainability at the highway corridor level.
The contents of this report contribute to the foundational research for megaregional transportation resilience planning. Megaregions contain the majority of America's population and economic centers, and experience various levels of devastating impacts as a result of gradual climate change impacts and natural disaster threats. This work defines transportation resilience and outlines existing funding sources available for resilience planning and projects. It also includes a spatial resilience case study that evaluates three megaregions bordering the Gulf of Mexico, a series of three-pager resilience profiles that outline major disaster threats to each U.S. megaregion, and examples of transportation resilience planning efforts to date. With federal financial assistance, state and regional transportation agencies have spearheaded the effort to collaborate on formal and informal forms of resilience planning at the regional and megaregional scale.
The report documents resilience efforts and how they are organized, understood, and implemented within transportation agencies' core functions and services. Core functions and services include planning, engineering, construction, maintenance, operations, and administration. The information gathered details the motivations behind the policies that promote highway resilience, definitions of risk and resilience, and the relationship between these two fields. The report also explores how agencies are incorporating resilience practices through project development, policy, and design.
No person or place is immune from disasters or disaster-related losses. Infectious disease outbreaks, acts of terrorism, social unrest, or financial disasters in addition to natural hazards can all lead to large-scale consequences for the nation and its communities. Communities and the nation thus face difficult fiscal, social, cultural, and environmental choices about the best ways to ensure basic security and quality of life against hazards, deliberate attacks, and disasters. Beyond the unquantifiable costs of injury and loss of life from disasters, statistics for 2011 alone indicate economic damages from natural disasters in the United States exceeded $55 billion, with 14 events costing more than a billion dollars in damages each. One way to reduce the impacts of disasters on the nation and its communities is to invest in enhancing resilience-the ability to prepare and plan for, absorb, recover from and more successfully adapt to adverse events. Disaster Resilience: A National Imperative addresses the broad issue of increasing the nation's resilience to disasters. This book defines "national resilience", describes the state of knowledge about resilience to hazards and disasters, and frames the main issues related to increasing resilience in the United States. It also provide goals, baseline conditions, or performance metrics for national resilience and outlines additional information, data, gaps, and/or obstacles that need to be addressed to increase the nation's resilience to disasters. Additionally, the book's authoring committee makes recommendations about the necessary approaches to elevate national resilience to disasters in the United States. Enhanced resilience allows better anticipation of disasters and better planning to reduce disaster losses-rather than waiting for an event to occur and paying for it afterward. Disaster Resilience confronts the topic of how to increase the nation's resilience to disasters through a vision of the characteristics of a resilient nation in the year 2030. Increasing disaster resilience is an imperative that requires the collective will of the nation and its communities. Although disasters will continue to occur, actions that move the nation from reactive approaches to disasters to a proactive stance where communities actively engage in enhancing resilience will reduce many of the broad societal and economic burdens that disasters can cause.
A multi-disciplinary approach to transportation planning fundamentals The Transportation Planning Handbook is a comprehensive, practice-oriented reference that presents the fundamental concepts of transportation planning alongside proven techniques. This new fourth edition is more strongly focused on serving the needs of all users, the role of safety in the planning process, and transportation planning in the context of societal concerns, including the development of more sustainable transportation solutions. The content structure has been redesigned with a new format that promotes a more functionally driven multimodal approach to planning, design, and implementation, including guidance toward the latest tools and technology. The material has been updated to reflect the latest changes to major transportation resources such as the HCM, MUTCD, HSM, and more, including the most current ADA accessibility regulations. Transportation planning has historically followed the rational planning model of defining objectives, identifying problems, generating and evaluating alternatives, and developing plans. Planners are increasingly expected to adopt a more multi-disciplinary approach, especially in light of the rising importance of sustainability and environmental concerns. This book presents the fundamentals of transportation planning in a multidisciplinary context, giving readers a practical reference for day-to-day answers. Serve the needs of all users Incorporate safety into the planning process Examine the latest transportation planning software packages Get up to date on the latest standards, recommendations, and codes Developed by The Institute of Transportation Engineers, this book is the culmination of over seventy years of transportation planning solutions, fully updated to reflect the needs of a changing society. For a comprehensive guide with practical answers, The Transportation Planning Handbook is an essential reference.
Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.
Infrastructure—electricity, telecommunications, roads, water, and sanitation—are central to people’s lives. Without it, they cannot make a living, stay healthy, and maintain a good quality of life. Access to basic infrastructure is also a key driver of economic development. This report lays out a framework for understanding infrastructure resilience - the ability of infrastructure systems to function and meet users’ needs during and after a natural hazard. It focuses on four infrastructure systems that are essential to economic activity and people’s well-being: power systems, including the generation, transmission, and distribution of electricity; water and sanitation—especially water utilities; transport systems—multiple modes such as road, rail, waterway, and airports, and multiple scales, including urban transit and rural access; and telecommunications, including telephone and Internet connections.
