This study evaluates the functionality of current maritime resolution systems and the limited uptake of the Rotterdam Rules—despite their objective to provide legal certainty and uniformity for multimodal carriage since 2009—highlighting their relevance to digital processes. It situates online dispute resolution (ODR) within maritime law by examining doctrinal compatibility with admiralty jurisprudence and established arbitration frameworks, including high-court interpretations of party autonomy, fairness, and evidence standards. The research adopts an institutional–organizational perspective to position the proposed political-institutional paradigm within broader public, private, and compliance-governance structures that guide system integrity and mitigate risks of noncompliance and embedded bias. It clarifies jurisdictional limits and liability transitions along end-to-end transport chains to support structured, platform-ready ODR pathways for multimodal disputes. The analysis also notes that existing treaty frameworks do not preclude the use of electronic processes, offering interpretive space for digital adjudication. The model emphasizes coordinated standard-setting by the International Maritime Organization, the Baltic and International Maritime Council, and the United Nations Commission on International Trade Law to ensure neutral, legally harmonized, and technically reliable ODR protocols. In line with cooperative principles reflected in instruments such as the Law of the Sea Convention, this study affirms ODR as a complementary and forward-looking mechanism. Analysis of 194 maritime cases shows ODR can yield nonarbitrary, efficient, and cost-effective outcomes, complementing the gradual evolution of instruments such as the Rotterdam Rules.]]></description><pubDate>Wed, 27 May 2026 10:48:02 GMT</pubDate><guid>http://pubsindex.trb.org/view/2706171</guid></item><item><title>Managing Highway Stormwater Quality: Driving Progress</title><link>http://pubsindex.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><pubDate>Tue, 26 May 2026 13:17:37 GMT</pubDate><guid>http://pubsindex.trb.org/view/2706309</guid></item><item><title>Developing a Guide for Local Truck Parking Regulations</title><link>http://pubsindex.trb.org/view/2703936</link><description><![CDATA[This report presents a report on local truck parking regulations that includes model ordinances, zoning code provisions, and strategies to support decisionmaking and implementation at the local level.

Concerns and considerations around truck parking are influenced by growth in population and economic activity, and amplified by recent events and trends like the Coronavirus (COVID-19) pandemic and the rise of e-commerce and global trade. A greater need for truck activity highlights the very human need for safe and secure parking for truck drivers. Although there are now more trucks on roads than ever before, there has not been a corresponding expansion in available truck parking. Studies report 11 truck drivers for every one parking space, and most drivers reported issues with finding safe truck parking. Building truck parking is often at conflict with land use goals in densely populated areas and constrained by local ordinances that may not reflect current parking demand. Effective local truck and trailer parking ordinances help keep truckers and other drivers safe, improve highway performance, reduce road maintenance costs, support economic growth, and promote community health and livability. This Guide presents a solutions toolbox and a range of model truck parking and staging ordinances, rules, and regulations suitable for consideration and adoption by local municipalities. The information documented in this Guide stems from a scan of available literature and local government policies, as well as stakeholder engagement with local agencies, truck drivers, and freight facility operators. This Guide is centered around truck parking needs for short-haul, long-haul, and drayage truck drivers in relation to the following key topic areas: staging, queuing, emergency road closure, vehicle breakdown, rest, human needs, and off-duty parking. Appendices present detailed information regarding case studies, infographics describing various truck types, and model ordinances, regulations and policies.]]></description><pubDate>Sat, 23 May 2026 18:35:19 GMT</pubDate><guid>http://pubsindex.trb.org/view/2703937</guid></item><item><title>Interdependence of Federal, State, and Local Transportation Funding and Ownership</title><link>http://pubsindex.trb.org/view/2701281</link><description><![CDATA[This report presents a guide to help state departments of transportation (DOTs) navigate funding and financing interdependence.

BABA stipulates that manufactured products and construction materials must be produced in the United States when federal funds are used to finance infrastructure projects. BABA expands previous legislation that required airfield infrastructure projects that used federal money, mostly Airport Improvement Program grants, to use products and materials produced domestically. However, the new BABA makes federal funds available for airport terminal projects beyond runway or taxiway projects. Under ACRP Project 11-01/Topic 16-01, “Buy America Requirements for Federally Obligated Airports,” Dempsey Aviation Consulting was asked to update the information in ACRP Legal Research Digest 18: Buy America Requirements for Federally Funded Airports (2013) to include new requirements under the Act. This includes the application of the domestic content thresholds; available waivers, other exceptions, and their practical implications; and considerations for management to achieve BABA compliance. The digest includes an appendix with a table that compares Buy America provisions in BABA in relation to prior legislation applicable to federal aviation projects and grant programs.]]></description><pubDate>Sat, 02 May 2026 15:47:05 GMT</pubDate><guid>http://pubsindex.trb.org/view/2696859</guid></item><item><title>Data Protection and Privacy Management at U.S. Airports: Guidelines</title><link>http://pubsindex.trb.org/view/2697804</link><description><![CDATA[This report provides U.S. airports with real-world use cases of data collection activities. Additionally, the report provides a thorough review of new technologies and processes, legal and regulatory trends, and the specific challenges that U.S. airports face when collecting, processing, and using data at an enterprise level. A detailed literature review includes a review of publicly available information on data management efforts of several airports. More than 20 airports were interviewed on their data collection efforts. That feedback was distilled into the use cases in this report. This report will be of interest to the staff at U.S. airports of all sizes, most notably airport leadership, legal staff, and airport information technology specialists.]]></description><pubDate>Sat, 02 May 2026 15:47:05 GMT</pubDate><guid>http://pubsindex.trb.org/view/2697804</guid></item><item><title>Midblock Pedestrian Crossing Volumes and Crash Rates in Milwaukee, WI</title><link>http://pubsindex.trb.org/view/2691798</link><description><![CDATA[Despite the majority of US fatal and severe pedestrian injuries occurring at midblock locations, few communities have collected counts to understand pedestrian midblock exposure and crash rates. This study developed a midblock pedestrian crossing count protocol and applied it to 61 street segments in the City of Milwaukee, WI. We counted midblock and adjacent intersection pedestrian crossings manually from 24-h video recordings. Midblock pedestrian crossings were common: 46 of the segments (75%) averaged more than one per hour. Among 48 segments with complete counts for both the midblock and an adjacent intersection crossing zone, 15 (31%) had more crossings in the midblock zone. We estimate that 17% of all pedestrian crossings along these 48 segments were midblock. Using these counts, we developed a negative binomial direct demand model of midblock pedestrian crossing volumes in Milwaukee. Midblock volumes were positively associated with nearby job density, commercial retail properties, and bus stops and negatively associated with posted speed limit and nearby parks. We demonstrated the value of this model by calculating pedestrian crash rates for all of our study segments and by estimating pedestrian crossing volumes for 133 additional street segments along seven roadway corridors. Expanding these methods beyond Milwaukee could lead to improved understanding of midblock pedestrian volumes and crash rates, ultimately helping communities reduce midblock pedestrian injuries and fatalities.]]></description><pubDate>Tue, 14 Apr 2026 10:08:40 GMT</pubDate><guid>http://pubsindex.trb.org/view/2691798</guid></item><item><title>Ripple Effects of Slot Deregulation: Evidence from Newark Liberty’s 2016 FAA Reclassification</title><link>http://pubsindex.trb.org/view/2691004</link><description><![CDATA[This study is an evaluation of the effect of the FAA’s 2016 decision to remove slot controls at Newark Liberty International Airport by reclassifying it from Level 3 to Level 2. Using flight-level data from 2014–2018, synthetic difference-in-differences, difference-in-differences, and synthetic control are applied in the analysis to estimate the policy’s effects on absorbed, propagated, and generated delays. Results show a clear trade-off. Absorbed delays increased by 6–8 min relative to the counterfactual, while propagated delays rose by 3–4 min, indicating greater tolerance of inbound disruptions and heightened transmission to subsequent flights. In contrast, generated delays declined modestly, by 0.5–1 min, suggesting some improvement in turnaround efficiency. Overall, deregulation reduced the creation of new inefficiencies but amplified existing disruptions across the network. The findings indicate the importance of balancing regulatory flexibility with measures to preserve resilience in congested airport systems.]]></description><pubDate>Fri, 10 Apr 2026 16:00:15 GMT</pubDate><guid>http://pubsindex.trb.org/view/2691004</guid></item><item><title>Commoning Cycling: Grassroot Initiatives for Inclusive Mobility Transitions Among People Facing Barriers to Cycling</title><link>http://pubsindex.trb.org/view/2686281</link><description><![CDATA[Improving the conditions for sustainable mobilities is the focus of considerable political and public attention. This paper identifies various ways that civil society initiatives promote cycling inclusion for marginalized groups facing barriers to cycling. An emphasis on commoning of cycling and cycling inclusion highlights how grassroot initiatives and their “commoners” take action to achieve an ambition to make cycling more inclusive in a bottom-up approach. In total, 12 initiatives have been studied, broadly categorized as bike kitchens, bike schools, bike to school, and bike promotion initiatives, located in Belgium, Greece, Italy, Portugal, Romania, and Sweden, respectively. These initiatives address groups that experience marginalization in the current mobility system (i.e., women with immigrant background, children, people with disabilities, seniors), and promote cycling through various forms of learning activities and skills to lower the thresholds to cycling and making cycling more diversified. The paper takes a holistic approach to shed light on the various ways that grassroot initiatives promote cycling inclusion, and, based on the experiences of participants and facilitators, explores what such initiatives may achieve given differences in context and target groups.?While the results show that cycling was mainly available for those participants that managed to adjust to the presumed norm of the confident, able-bodied, and individualized mobile subject, the initiatives had unexpected impacts on social dynamics of relevance to social justice. The results show the importance for cycling policy and planning to support concrete actions to improve the conditions for cycling to realize the full potential of cycling in the green transition.]]></description><pubDate>Fri, 03 Apr 2026 10:06:10 GMT</pubDate><guid>http://pubsindex.trb.org/view/2686281</guid></item><item><title>NCHRP Research Report 1115: In Case of Emergency: Easing Weight Limits for Commercial Trucks</title><link>http://pubsindex.trb.org/view/2678790</link><description><![CDATA[The Texas A&amp;M Transportation Institute recently concluded a comprehensive study to address the challenges state agencies face in managing regulatory relief for overweight commercial motor vehicles transporting supplies during emergencies. The research aimed to establish a unified approach to emergency management, focusing on the definitions of emergency and emergency commodities, identifying successful practices, and formulating a decision framework tailored to different emergency scenarios. The study, conducted under National Cooperative Highway Research Program (NCHRP) Project 3-13(05), “Regulatory Relief of Commercial Vehicle Weight Requirements for Emergency Transportation of Critical Commodities,” and resulting guide highlighted the importance of streamlining special permits in emergency situations. This need became apparent during the COVID-19 pandemic, when rapid changes in commerce increased demand on the freight community to deliver emergency supplies and goods amid uncertainty. The study noted the challenges posed by the lack of uniformity in permit regulations between neighboring states and within states that have multiple entities responsible for infrastructure ownership, operation, and local oversight. The study culminated in the creation of a comprehensive guide—NCHRP Research Report 1115: Transporting Freight in Emergencies: A Guide on Special Permits and Weight Requirements—that integrates best practices and essential resources.]]></description><pubDate>Thu, 02 Apr 2026 15:16:37 GMT</pubDate><guid>http://pubsindex.trb.org/view/2678790</guid></item><item><title>Sustainable Transportation in China: Review from 2014 to 2023</title><link>http://pubsindex.trb.org/view/2686117</link><description><![CDATA[With the acceleration of urbanization, how to promote sustainable transportation and achieve economic, environmental, and social benefits has become a focal point for researchers and policymakers. This study presents a systematic scoping review of sustainable transportation research in China from 2014 to 2023, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) framework. We analyzed 904 articles from the China National Knowledge Infrastructure and Web of Science databases bibliometrically and conducted an in-depth systematic review of 55 core publications after assessing their methodological quality with the Mixed Methods Appraisal Tool. Our analysis reveals eight dominant research themes: travel behavior, supply chain and logistics management, environmental impacts, sustainable transportation system planning, electric vehicles, shared mobility and public transportation, low-carbon transportation strategies and policies, and green transportation level assessment. Beyond these themes, this review critically identifies five persistent research gaps: climate adaptability, transportation system resilience, the application of Mobility as a Service, social sustainability and equity, and multi-departmental collaboration. The findings not only map the knowledge landscape but also highlight a systemic over-reliance on technological solutions, underscoring the need for more interdisciplinary and policy-implementation-focused research. This study provides a comprehensive baseline and future directions for researchers and policymakers, contributing to the global knowledge system on sustainable transportation.]]></description><pubDate>Mon, 30 Mar 2026 16:44:09 GMT</pubDate><guid>http://pubsindex.trb.org/view/2686117</guid></item><item><title>Exploring Motivations for Electrification of Ride-Sourcing Services: A Tripartite Evolutionary Game Perspective</title><link>http://pubsindex.trb.org/view/2684231</link><description><![CDATA[With the advancement in battery technology, electric vehicles have emerged as a feasible alternative for ride-sourcing. In various cities worldwide, policies promoting ride-sourcing electrification have been implemented. Despite these efforts, significant challenges remain, particularly with respect to the cooperative mechanism among various stakeholders. To address this issue, this study examines the motivations for ride-sourcing electrification through a tripartite evolutionary game framework, consisting of the government, ride-sourcing platforms, and ride-sourcing drivers. The basic model is constructed by considering factors such as social benefits, environmental benefits, subsidies, penalties, drivers’ commission rates, and transaction revenues. On the basis of this, the evolutionary stable strategies of each stakeholder and the system are analyzed. Further, a numerical study is conducted. The results indicate that the strategy of each stakeholder is influenced by the strategies of the others. Additionally, to promote the electrification of ride-sourcing more effectively, the government should consider both social and environmental benefits, as well as the balance between subsidies and penalties. For ride-sourcing platforms, attention should focus on the additional benefits resulting from electrification externalities. With respect to ride-sourcing drivers, their strategies are jointly influenced by factors such as revenues and commission rates. Based on these findings, this study offers valuable policy implications for both policymakers and platforms.]]></description><pubDate>Thu, 26 Mar 2026 13:38:05 GMT</pubDate><guid>http://pubsindex.trb.org/view/2684231</guid></item><item><title>Human-Centric Study for Setting Optimum Speeds on Speed Bumps Based on Rider Discomfort and Health Risk</title><link>http://pubsindex.trb.org/view/2684238</link><description><![CDATA[Speed bumps are widely implemented as physical traffic-calming measures because of their effectiveness in reducing vehicle speeds. However, they can impose significant discomfort and long-term health risks, particularly for riders of motorized two-wheelers, who are directly exposed to mechanical shocks. This study evaluates these impacts using two physiological metrics: vibration dose value (VDV), representing short-term discomfort, and static compressive stress (Se), indicative of spinal stress and long-term health risks. As an exploratory pilot study, field experiments conducted on three speed-bump geometries—350 mm, 500 mm, and 750 mm widths (each 50 mm in height)—suggest a trend whereby VDV decreases with increasing speed because of shorter exposure durations, while Se increases, reflecting heightened spinal stress. To balance these opposing trends, a risk factor (R) is introduced to quantify long-term health risk. The study proposes a framework for identifying optimum crossing speeds for each bump geometry, with our study suggesting values of 10 km/h for the 350 mm bump, 15 km/h for the 500 mm bump, and 20 km/h for the 750 mm bump under the stated commuter-exposure scenario. These optimum speeds correspond to a risk factor value below 0.8, indicating a low probability of adverse health outcomes. By integrating comfort and health metrics into a unified risk-based framework, this research provides actionable insights for safer and more inclusive speed-bump design—ensuring speed control without compromising rider well-being.]]></description><pubDate>Thu, 26 Mar 2026 09:34:21 GMT</pubDate><guid>http://pubsindex.trb.org/view/2684238</guid></item><item><title>Public Transport and Harassment of Women: Synopsis</title><link>http://pubsindex.trb.org/view/2684237</link><description><![CDATA[Harassment while using public transportation is an unpleasant but common occurrence for women who use public transport as their means of mobility. Despite the prevalence of harassment, the issue has not received sufficient attention in transportation planning and policy. In this research, we synthesize the existing literature on women’s harassment in public transportation, analyze key factors contributing to harassment, and propose policy recommendations to improve the current situation. This study also highlights how harassment remains a persistent issue in modern society, despite growing calls for equality and inclusivity. The findings emphasize the importance of addressing this challenge to support sustainable development and create safer, more equitable environments for all. Such factors as insufficient lighting, overcrowded transit, poorly organized bus stops, and difficulties during boarding and alighting are identified as significant contributors to harassment. Furthermore, the study highlights that victims often feel unsafe reporting incidents, owing to a lack of trust in authorities and social stigma. Fear of harassment negatively affects women’s mental, social, and personal well-being, limiting their mobility and participation in society. The paper concludes with the proposal of a 6Rs policy framework aimed at ensuring safe, secure, and efficient transportation for women, contributing to sustainable societal development.]]></description><pubDate>Thu, 26 Mar 2026 09:34:21 GMT</pubDate><guid>http://pubsindex.trb.org/view/2684237</guid></item></channel></rss>
