      <title>Ohio's Research Initiative for Locals (ORIL) Research on Call (ROC) FY2027-2029</title>
      <link>https://trid.trb.org/View/2761155</link>
      <description><![CDATA[Ohio's Research Initiative for Locals (ORIL) is a program designed to provide practice-ready solutions to real-world issues facing Ohio's local transportation system through research. It's a multi-organizational collaborative effort to improve the transportation network of Ohio's counties, townships, cities and villages. Additional information on the ORIL program is available on their website: http://oril.transportation.ohio.gov.  

Created in 2011, ORIL develops, funds and oversees transportation research projects to meet the needs of local agencies for the safety and economic well-being of the traveling public and Ohio. As of March 2023, ORIL has funded a total of 32 projects addressing issues specific to county, township and city roads. At times, situations arise where low-cost, short-term, focused research tasks are needed to address an urgent issue, identify best practices or synthesis existing research. While important and potentially impactful, these research tasks do not warrant the level of a full-scale research project. Due to the time-sensitive nature of these tasks, it is possible that some of these tasks go unmet because the standard contracting process requires more time than available. To address this issue, the ORIL Board has determined participation in Ohio Department of Transportation's (ODOT's) Research-On-Call (ROC) program is warranted. The ROC is designed to provide direct, quick access to researchers in specific areas of expertise to conduct short-term, focused, urgent research tasks.

      <title>Pavement Markings: Balancing Safety, Liability, and Maintenance Budgets</title>
      <link>https://trid.trb.org/View/2742790</link>
      <description><![CDATA[Pavement markings serve as fundamental traffic control devices, supplementing signs and signals to effectively convey regulations, warnings, and guidance to all road users. These markings are critical for improving safety for motorists, bicyclists, and pedestrians alike. The initial objective of this research was to address the “guidance gap” for medium-volume roadways—specifically those with traffic counts higher than typical low-volume local roads but falling below the 6,000 Average Daily Traffic (ADT) threshold where markings are strictly mandated. The goal was to help local agencies navigate decision-making for these intermediate corridors where standard high-volume guidance might be considered excessive or fiscally unsustainable. However, a 2025 statewide survey of 80 Minnesota local agencies revealed a significant operational reality: approximately 86% of counties already apply longitudinal pavement markings (centerlines and edgelines) to all paved roadways under their jurisdiction. This near-universal application is influenced by State-Aid rules and a commitment to systemic safety. In contrast, cities were found to be much more selective, typically marking only 18% to 33% of their paved systems, focusing primarily on collectors and arterials.]]></description>

      <title>Transition governance for sustainable urban freight systems : exploring small and medium-sized cities</title>
      <link>https://trid.trb.org/View/2752012</link>
      <description><![CDATA[Urban freight systems play an indispensable role in contemporary cities. By enabling the continuous flow of goods, they support economic activity and contribute to urban prosperity. At the same time, these activities generate substantial negative externalities, including emissions, noise, congestion and increasing pressures on urban space. As freight activities grow, their impacts intensify, underscoring the need to understand how urban freight systems can be transitioned toward sustainability. Urban freight systems are complex socio-technical systems embedded in broader societal contexts. Transitions of such systems are characterized by long-term, multi-actor processes involving the co evolution of interdependent factors. These processes challenge established practices, vested interests and structures, while simultaneously requiring actors to align with a normative direction of development. Existing knowledge about transitions in urban freight remains fragmented, with limited understanding of how system dimensions, governance arrangements and contextual factors interact in shaping transitions. This thesis addresses these gaps by exploring how transitions in urban freight systems are affected by different factors, such as city organizations' governance, with a particular focus on small and medium-sized cities, an understudied but important context. The thesis is based on four studies, three qualitative case studies of small and medium-sized cities and one systematic literature review. Together, these studies explore barriers to transitions, how city administrations in small and medium-sized cities govern their urban freight systems from a transition perspective and how city administrations' resources and governance activities affect their capability to govern these transitions.]]></description>

      <title>Effektivisering av godstransportsystemet : mått och komplexitet</title>
      <link>https://trid.trb.org/View/2752002</link>
      <description><![CDATA[Freight transport is a fundamental prerequisite for socio-economic development, business competitiveness, and the availability of goods, while at the same time accounting for a substantial share of Sweden's greenhouse gas emissions. Reducing the climate impact of transport without constraining economic development therefore constitutes a central challenge. Improved transport efficiency is often highlighted as a key strategy, yet its potential is difficult to assess since efficiency is defined, measured, and influenced in different ways across the many subsystems of the freight transport system. The aim of the project is to develop and operationalise appropriate, reliable, accessible, and cost-effective efficiency indicators for analysing the Swedish freight transport system, as well as to increase understanding of how efficiency measures affect different actors and system levels. The study applies a combination of top-down and bottom-up approaches to integrate a societal perspective with a firm-level perspective. Methodologically, the study is based on analyses of national statistics to develop efficiency indicators. Two indicators are developed: (1. climate-efficient freight transport [g CO2e/tkm], which relates greenhouse gas emissions to the amount of freight transported and the distance travelled, and (2. energy-efficient freight transport [MJ/tkm], which relates energy use to transport work. The analysis is complemented by empirical case studies on municipal freight consolidation, packaging design, and delivery service requirements. In addition, an analytical framework is developed to make visible causal relationships as well as trade-offs between efficiency, cost, environmental impact, and service level. The results show that transport efficiency in the freight transport system is a complex and multidimensional issue, where varying objectives, incentives, and system boundaries among actors complicate both analysis and governance. Efficiency improvements at the firm level may give rise to goal conflicts and sub-optimisation at the system level, and vice versa. The study therefore demonstrates the need for an integrated system perspective, in which firm-level indicators are combined with system-wide measures and where both relative efficiency metrics and total emissions are monitored. The project's results provide a knowledge base for more informed decision-making and future policy development towards a sustainable, competitive, and robust freight transport system.]]></description>

      <title>From Region to Relationships: Toolkit for Developing Multimodal Corridor Systems</title>
      <link>https://trid.trb.org/View/2709251</link>
      <description><![CDATA[State departments of transportation (DOTs) and metropolitan planning organizations (MPOs) utilize extensive resources and time to develop robust long-range transportation plans and asset management plans that are very policy based. In addition, they develop their very location-specific programs and program projects. However, apart from an area that may require National Environmental Policy Act (NEPA) analysis, there is an overall lack of tools to tie the statewide/regional/local policy plans to specific projects in (state) transportation improvement programs.

Corridor plans at either a statewide or regional level can provide states and MPOs with a tool to bridge this gap (especially among local jurisdictions) and to allow for a corridor-specific vision and plan. This corridor plan and vision will take the statewide/regional vision and goals, tailor them to the corridor, and then provide guidance and a framework when state and local agencies develop projects along that corridor. The primary function of these corridors (activity, multimodal, main street, freeways, arterials, etc.), their connections between surrounding land uses, and safety, mobility, and accessibility needs should be factored in.

OBJECTIVE: The objective of this research is to identify strategies for state DOTs to encourage local agencies to proactively generate multimodal master plans based on the long-term vision for the corridor and its surrounding land uses.]]></description>

      <title>Governing the transition to sustainable mobility in Sweden. Institutional pathways, political tensions, and the role of contentious car restrictive measures</title>
      <link>https://trid.trb.org/View/2684203</link>
      <description><![CDATA[In Sweden, as in many European countries, the ambition to reduce car dependency and promote sustainable mobility is increasingly reflected in municipal policy documents. However, the implementation of these ambitions remains uneven, constrained by institutional inertia, political caution, and selective problem framings. This paper identifies goal conflicts between different dimensions of sustainability that influence sustainable mobility transitions in Sweden. It concludes with a discussion of research needs arising directly from how sustainable mobility is currently framed and operationalized in municipal planning.]]></description>

      <title>Rescaling, collaborative governance and the emergence of penumbral planning spaces in Nordic public transport</title>
      <link>https://trid.trb.org/View/2683220</link>
      <description><![CDATA[The Nordic countries are often portrayed as frontrunners in sustainable development, combining high environmental ambitions with strong welfare systems and relatively high levels of public transport use. Yet transport remains a persistent and complex challenge. Emissions from the transport sector continue to be substantial, car dependency is deeply embedded in everyday mobility practices, and questions of accessibility, affordability and social justice have gained increasing attention. Addressing these challenges requires not only technological innovation and behavioral change, but also institutional arrangements capable of coordinating transport and land-use planning across scales and sectors.  In this context, collaborative governance has become a central feature of contemporary transport planning. In particular, the rescaling of planning responsibilities from local to regional levels has intensified the need for coordination between actors operating within different territorial and institutional logics. This essay reflects on the Swedish case of rescaled public transport planning and situates it within broader Nordic and European debates on soft and hard governance, multilevel planning and sustainable mobility transitions. It argues that rescaling has contributed to the emergence of penumbral planning spaces: hybrid governance arrangements that are neither fully formalized nor entirely informal but instead occupy an ambiguous middle ground between hard and soft spaces.]]></description>

      <description><![CDATA[Developing requests for proposals (RFPs) is an important part of a local agency's work. Local agencies regularly use RFPs to solicit the support of outside firms and consultants to conduct work that they cannot do internally. Ensuring local agency staff can efficiently develop RFPs that accurately address and communicate the proposed project's needs is critical to delivering a safe and efficient transportation network.]]></description>

      <description><![CDATA[Improving safety for people walking and bicycling requires more than infrastructure alone. It calls for a cultural shift toward shared responsibility, supported by the Safe System Approach and Minnesota’s Toward Zero Deaths framework. The tool was modified to develop an ADA version. The content in the tool helps agencies begin to build the foundation necessary to influence a culture of safety when planning pedestrian and bicycle infrastructure. The twelve strategies included as a part of the decision tree were chosen by the Technical Advisory Panel as potential strategies for consideration, not an exhaustive list, and should be applied using sound engineering judgment.]]></description>

      <title>Learning for deployment of robotaxis at scale</title>
      <link>https://trid.trb.org/View/2666538</link>
      <description><![CDATA["Robotaxis" (SAE level 4 automated vehicles) have already been deployed in key markets worldwide, most notably in the United States and China. This has demonstrated both the potential and challenges of services using this technology. In Europe, shared electric CCAM solutions are seen as one important enabler to meet EU's green-house gas reduction target. While national agencies, as well as EC have funded several CCAM pilot and demonstration projects, there are to-date no large-scale implementations of robotaxi services in the region. The study which is reported here involved a new constellation of partners and aimed to prepare the public sector for large scale deployment of automated vehicles in urban areas by: Taking stock of the commercial operation of robotaxi fleets that have already been deployed in cities in the United States and China, and by identifying “lessons learnt” from the public, operators, and administrators to be applied to the planning for commercial implementation of robotaxis in Europe and Sweden in particular. Methods used included interviews with stakeholders related to existing deployments, workshops, analysis of data, media and literature reviews, hands-on experience using robotaxi services in USA (primarily San Francisco) and China; leading to recommendations regarding critical factors to consider for the large-scale deployment of robotaxi services in Europe, with a focus on Sweden.]]></description>

      <description><![CDATA[An effective municipal street network is essential for regional development, supporting both mobility and public utilities. To achieve this efficiently, municipalities are required to adopt optimal maintenance strategies and make effective use of public funds. This research explores municipal street pavement maintenance, primarily in the north of Sweden. The work aims to enhance urban street maintenance by combining a sustainability framework, current pavement maintenance and management practices with pavement performance modelling. The research consists of five studies, each providing distinct insights.]]></description>

      <title>Sustainable development of archipelagic port infrastructures</title>
      <link>https://trid.trb.org/View/2666476</link>
      <description><![CDATA[Society's increased demands for environmentally, socially and economically sustainable maritime transport in the archipelago have brought new challenges to the development of port infrastructure. Local and regional level public authorities with archipelagic ports face an increased pressure to develop port infrastructures to meet international- and national regulatory guidelines to reduce greenhouse gas emissions and increase accessibility. This project explores regulatory policies and strategies as well as challenges at public authorities in planning of sustainable development of archipelagic port infrastructures. The project comprises a structured literature review of published scholarly papers and regulatory policies and strategies on sustainable development of archipelagic port infrastructures. It further includes a case study of two regions, four municipalities and six port authorities. Semi structured group interviews conducted in the case study comprise knowledge about regulatory policies and strategies and challenges in development of archipelagic port infrastructures. Based on the conducted structured literature review the project present a conceptual model showing that port infrastructure development takes place based on the interaction between regulatory guidelines, and directives at the three levels: 1. first international level, 2. second international level, and 3. national level. The project further shows that relevant national regulations in development of archipelagic port infrastructures comprise statutory acts on port development as well as on societal planning. The case study showed however a challenge in a lack of stakeholder knowledge regarding international and national regulations on development of archipelagic port infrastructures. Based on the case study results, the project further categorises challenges in sustainable development of archipelagic port infrastructures into the three categories: 1. collaboration, communication, governance, 2. funding, and 3. geographical and physical challenges (to meet accessibility requirements).]]></description>

      <title>Commercial Drivers License (CDL) Guidance for Local Agencies: Assisting Local Agencies' Understanding of Updated Requirements</title>
      <link>https://trid.trb.org/View/2636163</link>
      <description><![CDATA[Rulemaking published in 2022 by the Federal Motor Carrier Safety Administration (FMCSA) has increased the scrutiny and stringency of Commercial Driver’s License (CDL) requirements. This has added to challenges faced by local cities and counties, who need assistance in identifying and utilizing limited resources to facilitate staff training and certification. To meet this need, the Minnesota Local Road Research Board (LRRB) in collaboration with the Center for Transportation Studies Local Technical Assistance Program (LTAP), identified, compiled, and developed training resources to assist local agencies in understanding the requirements and resources available to ensure staff can attain CDL certification necessary to do their jobs in providing essential services for their community.]]></description>

      <description><![CDATA[Asphalt patching remains the most widely used method for pothole repair. While various technical resources are available, most workers still learn how to patch in the field. Additionally, numerous proprietary patching mixes have been introduced over the years, and local agencies are seeking information about their effectiveness. This study aims to update and build upon earlier LRRB resources (2017, 2018) by surveying local agencies to understand current patching practices, compare product performance, and summarize which materials and methods work best under various conditions. Key focus areas include: • Guidance on asphalt patching; • Performance information on proprietary patching products; • A summary of the best patching practices from Minnesota local agencies; and • Training and education video.]]></description>

      <title>EV Charging Best Practices</title>
      <link>https://trid.trb.org/View/2636116</link>
      <description><![CDATA[Electric vehicles (EVs) are becoming increasingly common in the United States (US). EV sales have been slowly increasing, with EVs becoming a noticeable part of the State of Minnesota (MN) vehicle fleet (growing from 4,900 vehicles statewide in 2018 to more than 78,000 vehicles as of July 20251 ). As EVs continue to become more common, public agencies are increasingly wrestling with the questions of how, when, and where to provide public charging facilities. The federal Bipartisan Infrastructure Law (BIL) created the National Electric Vehicle Infrastructure (NEVI) Formula Program, which was intended to provide federal funding to install public-facing fast chargers along interstate corridors and other roadways across the US. The State of Minnesota is expected to receive and invest about $68 million from the NEVI Formula Program over five years (federal fiscal year 2022 through 2026). The NEVI Formula is focused on building long-distance EV charging infrastructure and while some of these efforts may support local community charging, that is not the primary focus of the funding program. However, many local units of government (LGU) in Minnesota have stepped forward to begin filling that gap, and others would like to provide public charging facilities but don’t know where to begin. This report reviews and summarizes current practices and guidance from Minnesota agencies who provide EV charging to the public and provides recommendations and resources to help local agencies navigate siting, design, pricing, and other considerations.]]></description>
