      <title>Development of a Research Roadmap for ITD’s Bridge Section</title>
      <link>https://trid.trb.org/View/2693722</link>
      <description><![CDATA[The Idaho Transportation Department (ITD) Bridge Section has been at the forefront of advancing bridge materials, design, construction, preservation, and inspection in Idaho through sponsored research. However, the department acknowledges the necessity of evolving from past ad hoc research requests to a more proactive and systematic approach. The aim is to align research efforts, ensuring they complement and build on each other for more impactful outcomes. To achieve this, the following steps were taken: (1) a detailed assessment of ITD's deficiently rated bridge inventory including individual element condition states, (2) a nation-wide department of transportation (DOT) funding and research survey, and (3) a comprehensive analysis of both past and ongoing DOT-financed research projects over the past 5 years. This information was used to supplement ITD’s technical advisory committee expertise to generate a new list of high impact research queries tailored to Idaho’s specific needs and interests. This list was then organized by priority with the top six being chosen for additional investigation. By adopting this proactive strategy, ITD aims to enhance the efficiency and effectiveness of its bridge-related research endeavors, ultimately contributing to safer and more resilient transportation infrastructure.]]></description>

      <title>Developing a Roadmap for Ultra-High Performance Concrete (UHPC)</title>
      <link>https://trid.trb.org/View/2684169</link>
      <description><![CDATA[The objectives of this pooled fund study are to: (1) Facilitate communication and information sharing among member states on the project topic, as well as with participants of the Fourth International Interactive Symposium on Ultra High Performance Concrete (UHPC). (2) Establish a forum for technology and knowledge exchange to enhance the practical understanding of UHPC implementation among member states. (3) Develop a strategic roadmap for future UHPC use and advancements, including the identification of research needs and the formulation of research ideas to be pursued through NCHRP, Pooled Funds, grants and other funding mechanisms.

The anticipated benefits of this pooled fund are: (1) Minimized disruption to the traveling public by reducing the frequency and duration of bridge deck repairs. (2) Lower maintenance costs resulting from the enhanced durability and performance of UHPC wearing surfaces. (3) Improved worker safety through reduced exposure to on-site repair activities due to less frequent maintenance needs.

The participating state departments of transportation (DOTs) will provide input throughout the project and benefit from shared insights into technologies used to date, as well as lessons learned from past projects across various regions. Additionally, they will gain exposure to the latest advancements to be presented at the Fourth International Interactive Symposium on UHPC, which will cover topics including UHPC material innovations, recent applications, and the long-term performance of UHPC-designed structures. Pooled fund participants will attend the symposium free of charge.

      <title>Research, Development &amp; Technology Strategic Plan FY 2018-2022</title>
      <link>https://trid.trb.org/View/2675146</link>
      <description><![CDATA[This U.S. Department of Transportation (DOT) Research, Development, and Technology (RD&T) Strategic Plan presents DOT’s transportation research priorities and strategies to support the goals defined in the Department’s Strategic Plan for FY 2018–2022. This RD&T Strategic Plan is an update to the original plan published in 2017. This plan meets the requirement set forth in section 6503 of the Fixing America’s Surface Transportation (FAST) Act for the development of a five-year strategic plan to guide future Federal transportation RD&T activities. Although the scope of the FAST Act is limited to research and development (R&D) activities, the Department includes a “technology” component in its reporting and budgeting. The technology component represents the Departmental resources and activities allocated to the deployment of R&D outputs. The Department considers this to be an important part of its role, ensuring that research results are fully leveraged in the transportation system. Thus, this plan includes the Department’s strategic approach to technology deployment and is titled the “DOT Research, Development, and Technology (RD&T) Strategic Plan. The purpose of this plan is to improve the coordination of transportation RD&T, minimize redundancy, and guide the development of Annual Modal Research Plans (AMRPs) by each of the Department’s Operating Administrations (OAs). It also describes the processes used for planning, reporting, conducting, and evaluating RD&T across the Department. The Office of the Assistant Secretary for Research and Technology (OST-R) coordinated the development of this RD&T Strategic Plan and solicited input from the Department’s OAs.]]></description>

      <title>Electronic Institutional Review Board (eIRB) Usability Evaluation</title>
      <link>https://trid.trb.org/View/2658096</link>
      <description><![CDATA[The process of submitting an application for research involving human participants to the Institutional Review Board (IRB) at the Federal Aviation Administration (FAA) William J. Hughes Technical Center for Advanced Aerospace needs modernization. We conducted an evaluation of the first iteration of a newly proposed electronic Institutional Review Board (eIRB) system to assess its usability, provide insights and recommendations for improvements, and guide the eIRB system’s development to improve user experience. We used nine federal employees from the Technical Center, the Department of Transportation (DOT) at the Volpe Center, and Civil Aerospace Medical Institute (CAMI). We evaluated three pages within the system: the Registration page, the IRB Submission Form Fill page, and the Submit Protocol for IRB Review page. We also guided participants through four tasks: registering a protocol with the local Technical Center IRB, completing an IRB submission form, submitting a protocol, and submitting a protocol revision. Participants also completed the System Usability Scale (SUS) and answered additional survey questions pertaining to their experience using the eIRB system. We found that the overall eIRB system had above average usability although there are elements that need improvement. Several considerations must be made in the design and implementation of the eIRB system, especially considering the importance of remaining in compliance with federal regulations regarding the protection of participant Personally Identifiable Information (PII) and data management. The design of a system that allows users to easily and efficiently accomplish their goals is only half the battle; enforcement of compliance with the Common Rule and FAA Order 9500.25C for those engaging in research or test and evaluation activities involving human subjects must occur in order for eIRB system to serve its true purpose.]]></description>

      <title>R&amp;D investment strategies of robotaxi services: The role of cost variation and consumers’ trust</title>
      <link>https://trid.trb.org/View/2655809</link>
      <description><![CDATA[The promotion of robotaxi services can improve the efficiency and sustainability of urban transportation while requires substantial research and development (R&D) investment in relevant technologies. This study intends to investigate the strategies of R&D investment for robotaxi services by considering a supply chain that includes an automobile manufacturer, a robotaxi platform, and consumers. Two scenarios are considered, where either the automobile manufacturer or the robotaxi platform undertakes the investment. In addition, this study analyzes the effects of unit investment cost variations, consumer trust, and government subsidy. Further, this study extends the main models to incorporate the effects of market size variations, consumer-targeted subsidies, fleet size, and simultaneous investment. The results are presented as follows. (1) In both scenarios, the level of R&D investment is negatively affected by unit cost while positively impacted by government subsidy and consumers’ trust. (2) If the unit cost of R&D investment for the robotaxi platform exceeds that of the automobile manufacturer, the automobile manufacturer will undertake R&D investment. Otherwise, the robotaxi platform will undertake R&D investment. (3) Lower R&D investment unit cost, higher degree of government subsidy, and greater degree of consumers’ trust jointly promote the formation of equilibrium strategies. Nevertheless, whether the automobile manufacturer or the robotaxi platform undertakes R&D investment also depends on relative investment costs of both stakeholders. Therefore, this study offers both theoretical and practical implications for R&D investment in robotaxi services.]]></description>

      <title>Research Implementation Management System for the Oklahoma Department of Transportation</title>
      <link>https://trid.trb.org/View/2635933</link>
      <description><![CDATA[In the past, implementation of research project findings has been an informal process at the Oklahoma Department of Transportation. New federal requirements and Department needs have prompted the Office of Research to establish a formal set of standard procedures for implementation. The resulting Research Implementation Management System (RIMS) is a systematic process designed to improve the implementation of research project findings. This report presents a review of the literature, survey of states, and needs analysis performed to define the requirements of the system, then describes the procedures which comprise the RIMS. The RIMS procedures are categorized according to planning, execution, and evaluation phases. In the planning stage, proposals are evaluated for potential to produce practical, useful results, and acceptable projects have an estimated benefit/cost ratio calculated. After project completion, an implementation planning meeting is held where the strategies/tasks needed to achieve implementation are determined. A formal implementation plan is developed which includes the strategies, assigns responsibilities for tasks, and projects the time/resources needed to achieve the objectives. As the implementation plan is carried out (execution phase), activity is documented by responsible parties and progress is monitored/reported by the Project Manager and Implementation Manager. After three years, a Research Project Cost and Savings Report is prepared to summarize how the research findings were used, the total costs of the project and the implementation effort, and the estimated tangible benefits. The final benefit/cost ratio is compared to a preliminary estimate. The effectiveness of the implementation effort is evaluated annually by the Implementation Manager and recommendations for improvement made.]]></description>

      <title>Integrated Transportation and Health Impact Modeling Tool for U.S. Cities </title>
      <link>https://trid.trb.org/View/2652180</link>
      <description><![CDATA[The health of the American people is a national priority, and ensuring that transportation policies support strong communities, economic prosperity, and public well-being is a critical challenge that requires holistic solutions. This project will deliver groundbreaking research that directly informs transportation policies to improve traffic safety, air quality, and physical activity among transportation users in major American cities. These policies will help reduce preventable health burdens, cut healthcare costs, and enhance both community well-being and the cost-efficiency of our transportation systems. In the first stage of this project, we will review and update the underlying literature to refine and potentially extend the framework. We will develop updated visualizations to help transportation and public health agencies identify and communicate the various pathways linking transportation and health. By incorporating new evidence and addressing critical gaps, we will ensure the framework remains relevant for shaping future transportation policies at local, state, and national levels. During this stage, we will engage key stakeholders—such as transportation and public health agencies—by presenting our updated model, gathering their feedback, and enhancing our understanding of how transportation choices impact health outcomes. 
In the second stage, we will systematically collect, clean, quality-assess, harmonize, and integrate data from diverse sources to underpin subsequent quantitative modeling. This modeling exercise will examine pathways related to vehicle crashes/traffic safety, transportation-related air pollution, transportation-related physical activity, and any additional pathways deemed feasible for quantitative modeling based on data availability and strength of evidence. The data sources will include census population counts, geographic information system layers, transportation network layers and average vehicle speed data, household travel surveys, physical activity surveys, police crash records for fatal and non-fatal incidents, baseline health outcome rates, and associations between transportation factors and health outcomes as derived from systematic reviews and meta-analyses (i.e., dose- and exposure-response functions). This will allow us to construct a detailed and representative model of American mobility patterns, their health impacts through safety, air quality, and physical activity, and how targeted policies can mitigate risks and enhance benefits holistically across these pathways. We will focus on practical solutions that include policy instruments such as shifting a portion of trips to electric vehicles, electric buses, and electric bikes—while ensuring alignment with existing travel survey data for realism.

      <title>Can We Finally Address the Safety Crisis on U.S. Highways?</title>
      <link>https://trid.trb.org/View/2627330</link>
      <description><![CDATA[Motor vehicle death rates in the United States are about five times higher than in Australia, Canada, and Japan, as well as the safest nations in Europe. Do those countries have a secret formula to reduce their traffic fatalities? Does their road safety research tell them things that transportation professionals in the United States don’t know? These questions, posed by the Federal Highway Administration (FHWA) in collaboration with the American Association of State Highway and Transportation Officials (AASHTO) and the Insurance Institute for Highway Safety (IIHS), led to the appointment of the Transportation Research Board (TRB) Committee on Transitioning Evidence-Based Road Safety Research into Practice and precipitated their consensus study work. That work resulted in TRB Special Report 354: Tackling the Road Safety Crisis: Saving Lives Through Research and Action. This article discusses what the Committee found when analyzing U.S. road safety research selection, prioritization, and dissemination. The Committee found that the process for generating and converting road safety findings into practitioner guidance is complicated, slow, and episodic with guidance issued in multiple sources making it confusing and complicated to access and apply research findings. The article presents five recommendations made by the Committee to the U.S. Department of Transportation to improve the functioning of the road safety research supply chain including supporting ongoing evaluations of the effectiveness of crash countermeasures.]]></description>

      <title>Synthesis of Information Related to Highway Practices</title>
      <link>https://trid.trb.org/View/2617649</link>
      <description><![CDATA[Administrators, practicing engineers, and researchers continually face highway problems on which much information already exists, either in documented form or in terms of undocumented experience and practice. Unfortunately, this information is often fragmented, scattered, and under evaluated. Often it is unknown to the person normally responsible for initiating changes related to the topic (changes in specifications, procedures, etc.). As a consequence, full information on what has been learned about a valuable experience may be overlooked, and due consideration may not be given to recommended practices for solving or alleviating the problem.

OBJECTIVE: In this project, particular highway problems, or sets of closely related problems, are designated as topics for information synthesis. For each topic the project objectives are as follows: (1) locate and assemble documented information; (2) learn what engineering practice has been used for solving or alleviating the problem; (3) identify all ongoing research; (4) learn what problems remain largely unsolved; (5) organize, evaluate, and document the useful information that is acquired; and (6) evaluate the effectiveness of the synthesis after it has been in the hands of its users for a period of time.

      <title>Highway Research and Technology -- International Information Sharing</title>
      <link>https://trid.trb.org/View/2617648</link>
      <description><![CDATA[Highway authorities world-wide share many common concerns in the planning, design, construction, operation, and maintenance of highway systems. Most developed nations also support programs of research and development (R&D) on highway issues. The potential for information sharing and technology transfer is great. Coordination of research in the United States has focused primarily on technology transfer and information dissemination among the large and diverse community of state and local highway agencies within this country. There is a need to utilize a systematic exchange mechanism to learn from counterparts abroad, where many new developments have been tested and successfully used for highways. OBJECTIVE: The National Cooperative Research Program (NCHRP) 20-36 Project provides a coordinated approach to international information sharing and technology exchange. The project activities have a much broader scope than the typical NCHRP project in encompassing exchanges on all facets of highway technology, policy and management with our international partners. The project’s overall objective is to improve highway safety, development, maintenance and operations through dissemination of innovative technology and successful practices from around the globe. Such process enhances the roles of the American Association of State Highway and Transportation Officials (AASHTO), the Transportation Research Board (TRB) and the Federal Highway Administration (FHWA) in providing coordinated leadership for the exchange of international highway research and development, and provides state departments of transportation with information on practices and technologies that could help accrue technical and economic benefits. ]]></description>

      <link>https://trid.trb.org/View/2611084</link>
      <description><![CDATA[The Strategic Highway Research Program (SHRP) is a highly targeted, specially funded program focusing on six critical highway research areas: asphalt characteristics, long-term pavement performance, maintenance cost-effectiveness, protection of concrete bridge components, cement and concrete, and snow and ice control. SHRP will concentrate highly innovative research approaches on a few specific areas of highway technology that cannot be meaningfully addressed through incremental, separate projects. It is intended to supplement, not supplant, existing highway research programs. This 5-year, $150 million program has moved into a new phase with the publication of detailed research plans, the signing of a formal Memorandum of Understanding by the cooperating agencies, the appointment of a SHRP Executive Committee, and the appointment of an executive director. Further details are discussed in this article.]]></description>
