      <title>Health and Safety Impacts of Aircraft Cabin Temperatures</title>
      <link>https://trid.trb.org/View/2709677</link>
      <description><![CDATA[Commercial aircraft cabins expose passengers and flight attendants to a range of environmental conditions, including at times excessively hot or cold temperatures that may affect health, safety, and comfort. While aircraft systems are generally effective at maintaining acceptable cabin conditions, challenges are more likely to arise during ground operations, particularly in extreme outdoor temperatures or when equipment used for thermal control in aircraft cabins is unavailable or not functioning properly. Because passengers and flight attendants have limited ability to leave or substantially modify the cabin environment, understanding and managing temperature-related risks is an important component of safe air travel. This report examines the available evidence on how cabin temperatures and humidity conditions may influence physiological, cognitive, and behavioral outcomes for passengers and flight attendants. The report finds that serious health impacts are uncommon, but conditions causing thermal discomfort may occur more frequently and can affect factors critical to the conduct of flight attendant duties (e.g., concentration, decision-making) and passenger behavior in ways that create safety concerns. The report highlights differences in how passengers and flight attendants experience cabin temperatures because of variations in activity levels, clothing constraints, exposure frequency, age, and underlying health conditions. It also concludes that available data on cabin temperature and humidity conditions are fragmented and insufficient to reliably estimate the frequency of related health and safety events. The report provides recommendations to strengthen management of cabin temperature risks, including integrating temperature and humidity hazards into airline safety management systems, improving collection and use of aviation safety and health event data, strengthening operational practices for thermal control in aircraft cabins, supporting flight attendants in responding to unsafe conditions, and providing passengers with information about temperature-related risks. The report also recommends that the Federal Aviation Administration establish a research program to systematically collect representative data on cabin temperature and humidity conditions to better inform future mitigation strategies and safety oversight.]]></description>

      <title>Managing Highway Stormwater Quality: Driving Progress</title>
      <link>https://trid.trb.org/View/2706309</link>
      <description><![CDATA[Our roads are both a source of and a conveyance system for pollutants to bodies of water via stormwater runoff. This report focuses on engineering and infrastructure strategies to support state departments of transportation (DOT) decision-making regarding stormwater management approaches to comply with regulations. Administered by the U.S. Environmental Protection Agency (EPA), state permitting authorities identify each water body that does not meet a water quality standard due to pollutants. Updated modeling options that account for different land uses can better enable state DOT decision makers. Acknowledging the difference in pollutants that originate from highways (such as tire and brake wear contaminants) and pollutants that do not but are conveyed to water bodies (such as nutrients and bacteria from adjacent land) may improve source control. The report also identifies areas for collaboration between state DOTs, EPA, and Federal Highway Administration officials along with state environmental authorities. These partnerships could result in improved design, construction, and maintenance procedures and guidance. Participation in alternative watershed-scale approaches for managing highway stormwater may also result in practical and desirable outcomes.]]></description>

      <title>Clinical Follow-up and Care for Those Impacted by the JP-5 Releases at Red Hill</title>
      <link>https://trid.trb.org/View/2683257</link>
      <description><![CDATA[Communities served by the Joint Base Pearl Harbor–Hickam water distribution system were directly impacted following two major releases of jet propellant 5 (JP-5) aviation fuel from the Red Hill Bulk Fuel Storage Facility in May 2021 and November 2021. While human error initially contributed to these incidents, the responses to these leaks could also be seen as a sequence of potentially avoidable errors that led to ongoing confusion and mistrust about the safety of the water supply and the impact on the health of communities affected by the fuel leaks. An ad hoc committee of the National Academies of Sciences, Engineering, and Medicine was convened to recommend further guidance on clinical actions to monitor the long-term health of community members exposed to JP-5 aviation fuel releases. Informed by its community engagement and use of core public health functions, the committee adapted two complementary frameworks developed for prior National Academies studies, the evidence to decision framework from "Guidance on PFAS Exposure, Testing, and Clinical Follow-up" (2022) and the ethical framework from "Evidence-Based Practices for Public Health Emergency Preparedness and Response: Assessment of and Recommendations for the Field" (2020), to guide its development of recommendations. Additionally, the committee drew from Native Hawaiian values, including kuleana (delegated authority and corresponding responsibility) and mālama ‘āina (care for the land). Through these complementary ethical lenses, the committee aimed to provide recommendations that are evidence based, equitable, culturally grounded, and responsive to the needs of affected communities. Although there has been substantial progress toward remediating the spilled fuel and closing and defueling the Red Hill fuel tank facility, sustained environmental monitoring, clinical follow-up, and deliberate efforts to rebuild trust remain essential to achieve optimal health outcomes for affected individuals and communities and to strengthen the systems that safeguard public health and environmental stewardship. The committee’s recommendations are organized according to the three core public health functions of assurance, policy development, and assessment. Together, these functions represent a pathway toward appropriate clinical care, healing, and resilience for communities affected by the Red Hill fuel releases.]]></description>

      <title>Reforming the Coast Guard's Certificate of Compliance Program for Liquefied Gas Carriers: Promoting Efficient Implementation and Safety Effectiveness</title>
      <link>https://trid.trb.org/View/2672508</link>
      <description><![CDATA[As liquefied gas exports from U.S. ports have grown rapidly in recent years, reforms are needed to a U.S. Coast Guard program that examines liquefied gas carriers (LGCs). Going forward, this growth in LGC exports and arrivals is likely to increase the demand for gas carrier exams by Coast Guard marine inspectors, of which there is a chronic shortage. This Special Report was requested by Congress out of concern for the Coast Guard's ability to examine the increasing number of foreign tank ships that load liquefied gas for transport overseas. The National Academies' committee concluded that the time is right for Congress to revisit the Certificate of Compliance program's requirements mandating the frequency of exams and to allow the Coast Guard greater flexibility to decide when and how to examine individual LGCs using indicators of risk.]]></description>

      <title>Innovative Materials in Water Resources Infrastructure: Opportunities for the Corps of Engineers</title>
      <link>https://trid.trb.org/View/2644576</link>
      <description><![CDATA[Through its Civil Works program, the U.S. Army Corps of Engineers (USACE) is responsible for planning, building, maintaining, and operating much of the nation’s water resources infrastructure for navigation and flood risk management. In particular, the maintenance, repair, rehabilitation, and modernization of water resource assets present demanding and costly challenges for USACE. The infrastructure assets and their components can be unique, built and manufactured at different periods for certain site-specific needs and conditions. In addition, these assets are subject to the stresses of water environments and to mechanical damage from vessels. Most of the navigation and flood risk management structures were built during the middle decades of the 20th century, meaning that a large majority of them have exceeded or will soon exceed their estimated design service lives of 60 to 75 years. In the Water Resources and Development Act of 2016, Congress called for a study by an expert committee of the National Academies of Sciences, Engineering, and Medicine to consider the key demands and challenges facing USACE related to the condition and performance of its navigation and flood risk management assets; examine how innovative materials can support capabilities critical to meeting these demands and challenges; and make recommendations to inform strategies that USACE can pursue to further the development, demonstration, and deployment of promising materials in new and existing infrastructure. The results of this requested study are documented in this report.]]></description>

      <title>Peer Review of the Federal Aviation Administration's Study of the Effects of Passenger Seat Width and Pitch on Airplane Evacuation Performance</title>
      <link>https://trid.trb.org/View/2570651</link>
      <description><![CDATA[TRB Special Report 358 presents a peer review of a research project conducted by the Federal Aviation Administration’s (FAA's) Civil Aerospace Medical Institute (CAMI) to assess whether airplane evacuation times can be affected by variations in passenger seating space, and particularly the dimensions of seat width and seat pitch. CAMI requested the review because of FAA’s interest in knowing whether the project’s results may be informative to pending decisions about whether to regulate the width and pitch of passenger seats. Of concern is that constrained seat space may interfere with cabin evacuations during an emergency, especially because the average body size (e.g., girth, weight) of Americans has been increasing. In this regard, the findings from the review suggest that CAMI’s research project does not provide the information needed for the proposed purpose. The project’s fundamental shortcoming is that it does not directly assess how seat width and pitch interact with passenger body size variables to affect evacuation performance, and especially for plausible scenarios in which the number and concentration of people with large body sizes on a flight may differ from the pattern for the flying public generally.]]></description>

      <title>The Air Traffic Controller Workforce Imperative: Staffing Models and Their Implementation to Ensure Safe and Efficient Airspace Operations</title>
      <link>https://trid.trb.org/View/2569142</link>
      <description><![CDATA[Air traffic controller staffing is essential for aviation safety in the United States. Therefore, the Federal Aviation Administration (FAA) should continue to increase air traffic controller hiring, improve training success rates, incentivize transfers from overstaffed to understaffed airports, and implement robust fatigue management systems and efficient shift-scheduling tools. FAA should also rebuild its controller staffing based on its traditional modeling approach—as refined by needed updates and with local input—rather than adopting newer facility staffing models the agency developed collaboratively with members of the National Air Traffic Controllers Association. FAA should also conduct recommended research to improve understanding about the relationship between facility staffing levels and safety and validate its facility models using risk indicators, some of which are confidential and therefore not available to the committee that prepared the report. These are among the recommendations in this report (TRB Special Report 357) from the Transportation Research Board of the National Academies of Sciences, Engineering, and Medicine. The report, called for by Congress, notes that about 30 percent of the FAA facilities are staffed at more than 10 percent below their staffing targets and about 30 percent of facilities are staffed at 10 percent or more above their staffing targets. FAA experienced a series of externally imposed constraints on hiring since 2013, including two government shutdowns over budget and fiscal policy and the COVID-19 pandemic, that have notably affected several of the largest facilities that serve many of the country’s largest airports and have had an outsized effect on passenger delays.]]></description>

      <title>An Assessment of Data, Tools, and Metrics for Equity in Decisions About Surface Transportation Investments</title>
      <link>https://trid.trb.org/View/2487449</link>
      <description><![CDATA[In 2022, Congress directed the U.S. Department of Transportation (USDOT) to sponsor a consensus study by the National Academies of Sciences, Engineering, and Medicine (the National Academies) to advise on ways to further the use of metrics to inform choices about surface transportation programs and projects that will advance equity. This report is the product of an expert committee of researchers and practitioners convened to fulfill the request to identify promising metrics and analytical tools for decisions that will lead to safer and more reliable access to essential destinations for life outcomes and to consider resulting impacts on people’s health and well-being. The advice in this report is intended, in part, to inform a subsequent National Academies’ study called for in the legislation to pilot test promising approaches to equity analysis under the auspices of the Transportation Research Board’s (TRB’s) Cooperative Research Program (CRP). To inform its recommendations, the committee reviewed practices used by state governments and metropolitan planning organizations for transportation equity analysis with emphasis on outcomes stressed in the study charge—safe and reliable access to housing, employment, health care, and education, as well as health impacts and other environmental justice interests. The committee looked for innovative approaches that could be applied more widely to improve the state of practice in equity analysis. As directed by its charge, the committee consulted a preceding TRB report that advised on actions the USDOT should take to elevate equity in its competitive grant programs, and that pointed to a high degree of variability in the capacity of states and localities to undertake equity analyses. The study committee’s recommendations are applicable to states, local governments, regional planning organizations, tribes, and other organizations that receive federal aid for transportation projects. The report is organized in five chapters. Chapter 1 provides an introduction. Chapter 2 offers a causal chain analysis framework for understanding the causal pathways through which transportation investments may affect societal outcomes amid other nontransportation influences on these outcomes. The chapter summarizes literature on the contribution of transportation to societal outcomes in domains of life important to equity. Chapter 3 summarizes current practices, including indicators and metrics, used to assess equity by state departments of transportation and regional and local governments. Chapter 4 considers new and innovative approaches for advancing equity assessment in three areas: proximity to destinations as a measure of accessibility, transportation insecurity as a measure of transportation need, and environmental justice concerns, including disparities in health and safety. Chapter 5 presents the committee’s recommendations and suggestions for piloting equity metrics and supporting their widespread adoption to inform transportation decisions by states, localities, regional planning organizations, tribes, and other recipients of federal surface transportation funds.]]></description>

      <title>Pay and Working Conditions in the Long-Distance Truck and Bus Industries: Assessing for Effects on Driver Safety and Retention</title>
      <link>https://trid.trb.org/View/2441686</link>
      <description><![CDATA[This Consensus Study Report considers how compensation methods and working conditions in the long-distance for-hire trucking and intercity bus industries may affect the safety performance and retention of industry drivers. To conduct the study, the National Academies appointed an interdisciplinary committee whose members possess expertise in commercial motor carrier operations, safety regulation, transportation economics, statistics, freight planning, and transportation logistics. The report is organized into seven chapters. Chapter 1 provides an introduction. Chapter 2 provides background on the long-distance for-hire truckload (TL) sector and its operations and describes the truck driver workforce. It also describes the regulatory environment for the long-distance trucking industry by providing an overview of the main bodies of pertinent federal regulations governing safety and labor standards. Chapter 3 also provides background by describing the types of compensation used in the long-distance TL sector, distinguishing between piece rate forms of compensation and non-piece rate forms. The chapter also describes the work requirements and conditions experienced by drivers in the long-distance TL sector. Chapter 4 focuses on driver retention in the long-distance TL sector and explains the role that compensation methods, working conditions, and complex economic forces can have on the rates of driver retention and turnover. Chapter 5 reviews the research and empirical evidence about how compensation methods, non-wage rewards, and work conditions can affect safety in the long-distance TL sector. Issues associated with driver compensation, safety, and retention in the intercity bus industry are considered in Chapter 6, albeit to only a limited degree because of a dearth of information. Chapter 7 summarizes the key conclusions from the study and contains the committee’s recommendations pertaining to follow-on research. This chapter concludes with ideas for research and data collection that the Federal Motor Carrier Safety Administration (FMCSA) could pursue to further the recommendations.]]></description>

      <title>Long Freight Trains: Ensuring Safe Operations, Mitigating Adverse Impacts</title>
      <link>https://trid.trb.org/View/2433881</link>
      <description><![CDATA[In response to a congressional mandate, this consensus study report examines the safety challenges arising from the operation of longer freight trains, and particularly from the increased use of longer manifest trains that transport a mix of freight in many different types of rail cars. The report also examines the impacts of increasing freight train length on the frequency and duration of blocked highway-rail grade crossings and the scheduling and efficient operations of Amtrak intercity passenger trains. The report is organized in 7 chapters. Chapter 1 provides an introduction to the study. Chapter 2 describes the operational and safety challenges of long trains and examines why these challenges are particularly acute for long manifest trains. Chapter 3 examines the technologies used to control long trains and ensure operational safety, including engineer-assist systems, braking systems, and distributed power locomotives. Chapter 4 examines issues related to crew and railroad employees and their preparedness and experience in operating, inspecting, and maintaining long trains. Chapter 5 examines the safety impacts of long trains on the public, namely on the functioning of highway-rail grade crossings and on Amtrak intercity passenger rail service. Chapter 6 reviews the ways long trains can affect greenhouse gas emissions from rail transportation and from other modes and have other environmental impacts. Chapter 7 is a summary assessment of the report’s findings and contains the committee’s recommendations and their rationale.]]></description>

      <title>Tackling the Road Safety Crisis: Saving Lives Through Research and Action</title>
      <link>https://trid.trb.org/View/2434144</link>
      <description><![CDATA[To assess the effectiveness of road safety research and its implementation, the Federal Highway Administration (FHWA), the American Association of State Highway and Transportation Officials (AASHTO), and the Insurance Institute for Highway Safety (IIHS) asked the Transportation Research Board (TRB) to assemble an expert committee to study the process for transitioning evidence-based road safety research into practice and to recommend process improvements. The study committee expanded its interpretation of the statement of task to include the entire road safety research and development process, consisting of research project selection and funding as well as the conduct of research, the development and dissemination of guidance for practitioners, and the incorporation of feedback from the field to inform future research. The committee explored in detail the science of research translation in other fields. This consensus study report is presented in 6 chapters. Chapter 1 covers the study origins and Statement of Task and explains how the committee interpreted the Statement of Task. Chapter 2 describes the road safety crisis in the United States, provides an overview of the challenge of moving safety research from the perspective of practitioners, and introduces political and cultural factors unique to the United States that can make it difficult to put the best, proven crash countermeasures into practice. This chapter contrasts U.S. practice with approaches used with success in other nations, and it ends with an outline of the federal policy responses to road safety problems. Chapter 3 describes the current U.S. process of translating safety research through the use of a logic model with phases: (1) road safety research, (2) crash countermeasure implementation, and (3) before-after evaluation. Chapter 4 takes a deep dive into the challenges that can interrupt the flow of evidence-based research into the field. The chapter describes the standards and guidance used for road projects and examines the countermeasure deployment process in detail for planning and implementing  road safety countermeasures and countermeasure research. Chapter 5 reviews the general process of research translation, focusing on the medical field, where it is highly developed, and compares this to what is done in road safety, in search of strategies that might ensure that the most useful evidence-based research results will reach the users, both practitioners and road users themselves. Two other examples of research translation are examined for comparison: policy research on early childhood education and safety research in the motor vehicle industry. Chapter 6 summarizes the committee’s analysis and then provides its recommendations. Throughout the report, selected sidebars describe examples and case studies for context.]]></description>

      <title>Intermodal Chassis Provisioning and Supply Chain Efficiency: Equipment Availability, Choice, and Quality</title>
      <link>https://trid.trb.org/View/2427792</link>
      <description><![CDATA[This study by an independent committee was conducted at the request of Congress and sponsored by the Federal Maritime Commission (FMC) to review existing approaches in the United States for provisioning intermodal chassis for the drayage or short-distance movement of shipping containers. Most general cargo in international commerce moves in standardized, 20-ft, 40-ft, or 45-ft steel box containers. Designed and sized specifically for transporting these containers on the highways, chassis are truck trailers consisting of a frame, two or three axles, and mechanisms for locking the container in place. Chassis are used by motor carriers to transport imported containers arriving at seaports and rail terminals to their final destinations. They are also used to transport containers used for exporting containerized cargo from their origins to railroad terminals and international gateway ports. This report synthesizes the views on chassis provisioning practices offered by dozens of consulted participants in the intermodal container shipping enterprise, including ocean carriers, railroads, motor carriers, IEPs, pool managers, and shippers of containerized cargo, known as beneficial cargo owners (BCOs). The purpose of the consultations was to inform the study committee’s identification of key advantages and disadvantages of alternative approaches for chassis provisioning and fleet management when taking into account different drayage market  circumstance and conditions, such as port size, geography, traffic activity, and operational complexity. The goal was to evaluate whether the approaches have aligned incentives with regard to equipment ownership, management, maintenance, and provisioning that promote supply chain efficiencies.]]></description>

      <title>Emerging Hazards in Commercial Aviation—Report 2: Ensuring Safety During Transformative Changes</title>
      <link>https://trid.trb.org/View/2417195</link>
      <description><![CDATA[At the request of Congress, the National Academies of Sciences, Engineering, and Medicine has initiated a series of reports that this 10-year project will produce. Over a 10-year period, the project aims to review and advise on data and methods for identifying emerging hazards in the evolving U.S. commercial air transportation system. This is the second of six reports and focuses on safety management for new entrants and for transformative changes to technologies and operations that cannot simply just apply current methods. “Transformative changes” are defined here as changes that are sufficiently novel that their impact on safety and risk cannot be extrapolated from current data and analysis methods. Such changes are highlighted in the potential systemic stressors noted in the first report with “new entrants” and “new technologies and operations.” This report frames its analysis using the established principles applied in aviation safety management. Safety management occurs across the entire lifecycle of technologies and concepts of operation, from their design, through their implementation via production, operations, and maintenance. First, the committee examined how to identify and address emerging safety concerns via safety risk management with transformative changes to technology and operations. Second, examining safety assurance, the committee noted that, while extensive data gathering activities support monitoring of current concerns, gaps exist in data and analysis methods for predicting new hazards that may emerge with transformative technologies and operations; similarly, methods for predicting and then continuing to monitor for safety concerns are vital to the safe implementation of transformative changes to technology and operations. Third, examining safety policies and promotion across the organization, the committee noted in its first report how the Federal Aviation Administration's (FAA’s) assessment of its internal safety culture was then in a formative state requiring further development and review. In this report the committee follows up on the present status of FAA’s safety culture assessment and extends this discussion to the question of how to foster and monitor the safety cultures of organizations across the industry.]]></description>

      <title>Ensuring Timely Pipeline Shutdowns in Emergencies: When to Install Rupture Mitigation Valves</title>
      <link>https://trid.trb.org/View/2339970</link>
      <description><![CDATA[As of April 2022, the Pipeline and Hazardous Materials Safety Administration (PHMSA) requires installation of rupture mitigation valves (RMVs) on newly constructed and replaced segments of hazardous liquid and gas transmission pipelines. This study assesses regulatory standards and criteria for deciding when automatic and remote-control shutoff valves (i.e., RMVs) should be installed on existing pipelines in high consequence areas. The report includes coverage of pipeline incidents, an overview of the regulatory framework, and criteria for making decisions for when to install valves on existing pipelines. Lastly, observations about the current regulatory direction and guidance are provided to pipeline operators for deciding when to install RMVs on existing pipelines and for inspectors to verify that all obligations for deliberate and informed decisions are being met. Conclusions based on this assessment are presented along with recommendations for strengthening the guidance provided and verification methods used for ensuring sound decisions.]]></description>

      <title>Elevating Equity in Transportation Decision Making: Recommendations for Federal Competitive Grant Programs</title>
      <link>https://trid.trb.org/View/2308324</link>
      <description><![CDATA[Transportation systems in the United States have created safety and environmental burdens, conferred mobility benefits, and had positive and negative economic and social effects that have not been distributed equitably across communities and populations. While laws and policies put in place over several decades to remedy and prevent inequities have had mixed success, recent legislation and White House executive orders have placed increased emphasis on furthering transportation equity. Many of the U.S. Department of Transportation’s (U.S. DOT’s) competitive grant programs, which now account for about one-third of total federal funding assistance for surface transportation, have prioritized equity as a core goal and U.S. DOT is committed to ensuring that all of its programs are resolute and purposeful in taking equity into account. Recognizing the opportunities to advance equity directly through transportation project funds awarded competitively, and cognizant of the potential to leverage the federal competitive grant programs to spur equity-oriented transportation planning and decision making generally, the Transportation Research Board (TRB) and U.S. DOT’s Office of the Assistant Secretary for Research and Technology (OST-R) co-sponsored this study to advise on ways to achieve these desired outcomes. The study is the first in a series of three equity-related TRB studies. This report is the product of an expert committee convened to fulfill the original study’s charge to advise U.S. DOT on opportunities to elevate equity in its competitive grants programs. The study’s charge calls for the identification of data, metrics, and analytic methods that can be used by grant applicants to assess and report on the equity implications of their projects and that should be considered by U.S. DOT in making decisions about grant awards that enhance equity for overburdened and underserved communities.]]></description>
