SSCs have been introduced in various cities and are steadily expanding in use both in the U.S. and internationally. The extensive literature review of domestic and international documents and research papers reveals that the U.S. has been comparatively slow to adopt SSCs, with some other countries implementing these systems more extensively and earlier. Many local agencies are eager to learn SSC best practices and implementation lessons within the U.S. context. In this research, key issues related to SSC implementation are explored through semi-structured interviews with the agencies possessing extensive SSC-related experience in the U.S. The interviews were highly valuable in understanding differences across agencies and provided a greater depth of information than that found through publicly available websites and reports. Interview results indicate that these agencies are addressing similar issues with regard to equity, fines, evaluation, and technological advancements. However, the approach to these issues and the strategies employed to tackle them vary widely in scope, administration, and requirements. This research summarizes best SSC practices in the U.S. and finds that U.S. cities are innovating in the realm of new approaches to enhance traffic law compliance, performance measures, targeting dangerous drivers, providing open data, and integrating equity criteria and considerations into their programs.]]></description><pubDate>Tue, 05 May 2026 10:16:53 GMT</pubDate><guid>http://pubsindex.trb.org/view/2697865</guid></item><item><title>Creating a Guide to Advance the Art and Science of Decision-Making</title><link>http://pubsindex.trb.org/view/2666822</link><description><![CDATA[This conduct of research report, along with NCHRP Research Report 1162: Advancing the Art and Science of Decision-Making: A Guide, is based on the idea that the leaders of transportation agencies serve an essential role as decision-makers. Fulfilling this role effectively relies on their ability to do so quickly, accurately, and with agility in the face of changing circumstances. A host of factors make this especially challenging: incomplete information, complex organization, social, and political dynamics, limited timeframes, and flawed shortcuts and mental biases. This research combined the latest evidence-based theories from decision science with the direct insights and advice of some of the country’s most experienced agency leaders. The result is a guidebook with actionable strategies to identify, understand, and overcome the most common and serious challenges to reaching good decisions while reducing the overall mental and time burden required. The guide has three primary components that form the core research findings and results: Foundations of Decision-Making – A succinct review of what the latest cognitive science teaches us about how we make decisions; Strategies for Better Decisions – Actionable strategies and tactics for each of the identified challenges that can disrupt good decisions; and Case Studies of Decisions in Action – Stories of real-world high-stakes decision situations as told by the agency leaders who experienced them.]]></description><pubDate>Sat, 14 Feb 2026 19:11:43 GMT</pubDate><guid>http://pubsindex.trb.org/view/2666822</guid></item><item><title>Improving Virtual Public Involvement in Transportation Agencies</title><link>http://pubsindex.trb.org/view/2669189</link><description><![CDATA[Virtual public involvement (VPI), defined by the Federal Highway Administration as “the use of digital technology to engage individuals or to visualize projects or plans,” is now an essential part of public participation in transportation planning and project development. VPI has reduced participation barriers for many people while creating challenges for others. Although VPI was growing before the COVID-19 pandemic brought it into the mainstream, its rapid adoption has left agencies with limited guidance on selecting, customizing, and effectively using VPI tools. NCHRP Research Report 1178: Improving Virtual Public Involvement in Transportation Agencies, produced by TRB’s National Cooperative Highway Research Program, presents key principles and practical tips for VPI use by both beginning and experienced public involvement practitioners, project managers, and other professionals. The report is designed to help practitioners select, create, use, and evaluate VPI tools and techniques for transportation plans and projects. It covers federal policy, guidance on planning for VPI, effective information for use in VPI, user experience design, addressing the digital divide, and preparing for and conducting effective VPI meetings. The report also includes a virtual toolbox with examples, best-practice recommendations, and practical tips for maximizing the benefits of each tool.]]></description><pubDate>Thu, 12 Feb 2026 15:29:13 GMT</pubDate><guid>http://pubsindex.trb.org/view/2669189</guid></item><item><title>Implementing the Agency Capability Building Framework to Activate Organizational Change</title><link>http://pubsindex.trb.org/view/2628404</link><description><![CDATA[In 2019, NCHRP Project 20-24(95) developed the Agency Capability Building (ACB) Portal and digital guidebook. The guidebook presents a framework, supporting tools, and resources for building transportation agency capabilities. This NCHRP Project 20-44(40) facilitates the use of the ACB by transportation agencies. The research approach includes validating the persistence of the framework, disseminating information about the value and content of the previous project, and supporting transportation agencies’ use of the ACB guidance delivered through the ACB Portal and online guidebook by continuing to enhance the resource base.]]></description><pubDate>Tue, 02 Dec 2025 13:46:35 GMT</pubDate><guid>http://pubsindex.trb.org/view/2628404</guid></item><item><title>What Do Local and Global Sensitivity Analyses Tell Agencies about Asset Management Decision Support Tools?</title><link>http://pubsindex.trb.org/view/2620631</link><description><![CDATA[Decision support models are widely used to make efficient decisions about the maintenance, repair, and renewal of aging transportation infrastructure. These decision support models often involve selecting several parameters to realistically represent the system while constraining the computational cost, which increases as the number of parameters increases. However, these input parameters are characterized by uncertainty in their properties and values, thus making it difficult to determine the correct parameters for the models confidently. Traditional or local sensitivity analysis provides insights into selecting appropriate values, but does not account for parameter interactions. Global sensitivity analysis helps identify the most influential parameters. Local and global sensitivity analyses were conducted using simulated input–output data from a life-cycle cost assessment model for planning highway infrastructure maintenance and rehabilitation. The sensitivity analysis helps explain changes in the magnitude of the output and the selected maintenance policy from changes in the model parameters. Local sensitivity analysis indicated that the optimal policy selected using default parameters provided results close to the optimal policy if any parameter changed. Using Sobol’s method, global sensitivity analysis showed the relative importance of all parameters in a model. The analyses provided insight into the selection of actual optimal policies under various scenarios characterized by the model parameters and the need to explore alternative inputs, such as the congestion level in the network. The findings underscore the need for adequate sensitivity analysis for model calibration and evaluation. Based on the findings, the paper includes a guide for using sensitivity analysis in practice.]]></description><pubDate>Sat, 08 Nov 2025 12:03:19 GMT</pubDate><guid>http://pubsindex.trb.org/view/2620631</guid></item><item><title>Development of the Human Factors Guidelines for Road Systems: Third Edition</title><link>http://pubsindex.trb.org/view/2618512</link><description><![CDATA[The objectives of this current project (NCHRP 22-46) are to: (1) prepare a Human Factors Guidelines for Road Systems, Fourth Edition (HFG4), which can be used by State Department of Transportations (DOTs) and other transportation agencies to integrate Human Factors (HF) principles into design and operations across roadway systems for all road users, (2) provide a supplement to the AASHTO Highway Safety Manual (HSM) with other safety tools and processes such as Road Safety Audits (RSAs), operational reviews, performance planning, and crash data analysis for road system design and operations, and (3) document (very broadly) the best available HF and road/user interaction research and practices in road safety analyses and design to optimize data-driven safety analysis and decision making. For this research, road users include, but are not limited to, drivers, pedestrians, bicyclists, motorcyclists, and electric scooter users. This final report summarizes the activities and results associated with the 22-46 project. The body of this report contains three technical sections: Section 1 provides an introduction to this report and the overall project. Section 2 summarizes the objectives, methods, and results of Tasks 1 through 6 (Assess Existing Human Factors Literature, Develop Draft Practitioner Survey, Conduct Practitioner Survey, Develop Recommendations to Update the Content of the HFG, Develop and Submit Interim Report, and Develop Updated Content for the HFG4).

The guidelines build on previous editions of Human Factors Guidelines for Road Systems by updating chapters as needed and according to priority, adding chapters on new HF topics, and including tutorial materials to promote understanding and use of the guidelines. The guidelines should be of value to state departments of transportation (DOTs) and other transportation agencies seeking to provide safer roadway systems for all users by effectively integrating HF principles into roadway systems decisions.]]></description><pubDate>Sat, 08 Nov 2025 12:03:19 GMT</pubDate><guid>http://pubsindex.trb.org/view/2618541</guid></item><item><title>Enhancing Disaster Resilience and Authentic Public Partnership in Transportation Practice: Negotiated Resilience Capability Maturity Model</title><link>http://pubsindex.trb.org/view/2606775</link><description><![CDATA[The status quo for infrastructure and community preparedness for climate disasters is not adequate for the intensifying climate-hazard landscape in many contexts, and this deficiency can be exacerbated by ineffective public involvement practices. Negotiated resilience is an emerging concept that acknowledges the evolving nature of resilience goals and the relationship between community engagement and climate-resilience outcomes. This study aims to enhance negotiated resilience outcomes for transportation agencies in the U.S. by codeveloping, with transportation practitioners, practical tools integrating disaster management capabilities (i.e., preparedness, rapidity, flexibility) with authentic public involvement practices. To achieve this objective, the study develops a capability maturity model (CMM) with indicators that transportation agencies may use to benchmark the effectiveness of negotiated resilience practices in achieving disaster preparedness in transportation systems. Additionally, this study develops a self-assessment tool that maps to the various capabilities in the CMM. Based on four rounds of targeted transportation expert interviews, the Negotiated Resilience Capability Maturity Model (NR-CMM) and tool are refined to reflect stakeholder feedback across multiple types of transportation agencies. The NR-CMM and self-assessment tool offer a practical method for state and local departments of transportation, metropolitan planning organizations, and other transportation agencies to assess their effectiveness across multiple areas affecting disruption absorption and community preparedness, including stakeholder involvement, internal and external education efforts, and disaster management.]]></description><pubDate>Thu, 09 Oct 2025 11:01:48 GMT</pubDate><guid>http://pubsindex.trb.org/view/2606775</guid></item><item><title>Advancing the Art and Science of Decision-Making: A Guide</title><link>http://pubsindex.trb.org/view/2602541</link><description><![CDATA[This document combines practical advice and experiences from transportation agency executives with the latest findings from cognitive science research to supplement leaders’ toolboxes for good decision making. This begins with defining the foundations of “good” decisions and understanding the human forces that influence how we all make decisions. It ends with case studies of real-world decision situations faced by agency leaders and a closer look at how they handled them. In between there are several sections of strategies for navigating common challenges and unique situations. These strategies serve as tools to deploy in select instances as circumstances require, rather than steps in a defined process to follow at all times.]]></description><pubDate>Sun, 28 Sep 2025 18:05:10 GMT</pubDate><guid>http://pubsindex.trb.org/view/2602541</guid></item><item><title>Developing Snapshots for Transportation Planning</title><link>http://pubsindex.trb.org/view/2591957</link><description><![CDATA[Transportation planning agencies and officials face a rapidly evolving technical, policy, legislative, and procedural environment. Agency professionals often seek the guidance of peers and experts to help them effectively address these challenges. Challenges include managing the demand for new transportation technologies and services within the confinements of existing streets, navigating the effects of growing e-commerce on travel patterns, managing resilience and risks, and implementing transportation planning in compliance with federal and state laws and regulations. This report, from the Transportation Research Board's (TRB's) National Cooperative Highway Research Program, documents the process of developing four Snapshots of Planning Practices, concise and visually appealing documents that report on current planning practices in use by transportation agencies in four practice areas: Complete Streets, Data Sharing for Performance Management, Collaboration on Local Freight Delivery, and Economic Analysis to Support Decision-Making.]]></description><pubDate>Wed, 20 Aug 2025 13:34:39 GMT</pubDate><guid>http://pubsindex.trb.org/view/2591957</guid></item><item><title>A Guide to Applying the Safe System Approach to Transportation Planning, Design, and Operations</title><link>http://pubsindex.trb.org/view/2591955</link><description><![CDATA[The Safe System approach is a holistic approach that provides a framework for making the U.S. national transportation system safer. It is based on building and reinforcing multiple layers of protection to prevent crashes from happening and minimize the harm caused when crashes occur. This safety approach differs from conventional ones because it focuses on human vulnerability and creates a system with many redundancies to protect all transportation users. This report from the Transportation Research Board's (TRB's) National Cooperative Highway Research Program, presents information for applying the Safe System approach among state departments of transportation and other transportation agencies.]]></description><pubDate>Wed, 20 Aug 2025 13:34:39 GMT</pubDate><guid>http://pubsindex.trb.org/view/2591955</guid></item><item><title>Data Integration, Sharing, and Management for Transportation Planning and Traffic Operations</title><link>http://pubsindex.trb.org/view/2562308</link><description><![CDATA[This report presents tools, methods, and guidelines for improving data integration, sharing, and management practices through case studies, proof-of-concept product development, and deployment assistance.

To increase future regional truck freight planning, this paper reports the survey results from 22 Virginia RPA freight planning practices. Some RPAs were interested in practices not yet undertaken: provision of parking during emergencies (of interest to half the respondents), incorporation of parking needs as part of zoning ordinances (one-third), and provision of locally funded parking areas (a quarter). RPAs were heterogeneous: none of the 50 practices interested all RPAs and, on average, a given practice interested just 23% of respondents. Practices rarely undertaken but of high interest included identifying critical gaps in the truck freight network, identifying load-restricted bridges affecting business deliveries, and incorporation of parking needs into zoning ordinances. Accordingly, one such practice was piloted with one RPA, demonstrating that having adequate off-site locations to situate trucks for unloading is a pressing problem. The survey and pilot revealed that truck freight planning can be encouraged by tailoring practices to tightly defined regional interests. One pilot question concerned how future land use might stimulate off-site parking demand near pickup or delivery points. The ability to give a rough answer quickly led to a resulting action item proposed by the locality: explicit consideration of truck parking within the county comprehensive plan. The results showed that although additional data can yield a more exact answer, sketch-level planning information was sufficient to initiate a collaborative effort between a state and a willing regional participant.]]></description><pubDate>Mon, 19 May 2025 16:38:38 GMT</pubDate><guid>http://pubsindex.trb.org/view/2553854</guid></item><item><title>Implementing Data Governance at Transportation Agencies: Volume 1: Implementation Guide</title><link>http://pubsindex.trb.org/view/2464335</link><description><![CDATA[This Guide was developed to help transportation agencies to implement data governance structures and practices – and advance the maturity of these practices over time. It recognizes that each agency may choose to implement data governance in a different way – based on its size, culture, priorities, external requirements, data management infrastructure and resources. The Guide is organized into four major sections: I. Introduction – provides an overview of data governance and reviews the benefits of implementing data governance at a transportation agency. II. Implementing Data Governance – presents a nine step process for initiating a data governance effort, and outlines options for establishing data governance roles and responsibilities. Provides several options for consideration based on agency size, goals and culture. III. Data Governance in Action – presents guidance for implementing nine common data governance practices, including tips for success and references to relevant examples. Highlights seven common implementation challenges and provides ideas for tackling them. IV. Resources – provides sources that can be consulted for further information as well as sample materials supporting data governance implementation. Appendix A – Provides a maturity model for assessing transportation agency data governance practices and identifying actions to advance maturity to a target level. This appendix provides cross-references to guidance sections about the actions recommended in the model to advance maturity.
