Department of Transportation. Federal Highway Administration AB - The Global Warming Solutions Act (GWSA) set targets for Vermont to reduce greenhouse gas (GHG) emissions to 80% below 1990 levels by 2050. Recognizing that transportation accounts for the largest share of the State’s total GHG emissions, the Climate Action Plan identified reduction in vehicle miles traveled (VMT) as a key pathway to meet targets and acknowledged the need to quantify the effect of smart growth strategies on VMT and GHG reduction in the Vermont context. This project explored the hypothesis that compact, mixed use development patterns generate fewer VMT and GHG emissions per person than more dispersed or rural settlement patterns. A model was developed relating built environment measures in Vermont communities to weekly per capita VMT estimates by leveraging passively collected, location-based services data. Several future scenarios were quantified to demonstrate the degree to which smart growth strategies can reduce VMT to meet transportation related GHG emission reduction targets and quantify the co-benefits of smart growth strategies beyond GHG emission reductions. Focusing future growth in areas with low VMT and emulating prototype smart growth communities were most effective in reducing weekly per capita VMT overall, reducing VMT by an estimated 10 miles per person per week compared to more dispersed growth scenarios. Smart growth strategies were demonstrated to contribute to over 15% of the annual GHG reduction needed to achieve the 2050 GWSA targets. Conversely, dispersed settlement patterns produced an increase in emissions of up to 20% of the annual target, working against other mechanisms to drive down annual GHG emissions. Future scenarios demonstrated the co-benefits of smart growth strategies on safety with 1 avoided traffic death and over 30 avoided traffic injuries per year; health with reduced physical inactivity mortality saving nearly 4 lives annually; and maintenance with reduced annual maintenance costs by over $1.5 million. Case study communities offered further insights on VMT and GHG reductions possible through implementation of smart growth strategies. Specifically, the scenario results for case study communities highlighted the need for jobs in proximity to denser, mixed land uses to achieve targeted VMT and GHG reductions; the opportunity to enhance the existing patterns in Vermont of denser centers surrounded by more rural areas through context sensitive modifications to density, land use mix, infrastructure, and proximity to jobs; and, the influence of regional neighbors on VMT where condensed movement patterns within town centers are often complemented by more expansive travel patterns to adjacent communities.

Office of the Assistant Secretary for Research and Technology AB - Rail anchors are integral to the rail industry due to their effectiveness in improving track stability, enhancing track resistance to longitudinal movement, and preventing thermal-related track failures. The resistance to longitudinal movement allows for maintaining Rail Neutral Temperature (RNT). Temperatures outside the RNT range can lead to derailments and other catastrophic failures. Despite the positive impact rail anchors have in the rail industry, research on the interaction between rail and anchors remains minimal. In this study, utilizing a modified Track Panel Pull Test (TPPT) setup, the interaction of rail and anchor is analyzed with varying temperatures under cyclic loading. Temperatures range from below freezing to extremely hot temperatures, with a range from -10°C (14°F) to 78°C (172°F). Furthermore, displacement-controlled testing procedures were utilized to obtain consistent slip forces, or longitudinal resistances, for specified displacements of the anchors. Temperature affects longitudinal resistance differently for different anchor types. Specifically, resistance consistently increases as temperature increases, but the magnitude of this effect varies by anchor design. From hot to cold temperatures, there was a 38%, 34%, and 32% drop in longitudinal resistance for Anchors X, Y, and Z, respectively.

With a low population density and high road density, the State of Maine has significant paving needs. The adverse climate conditions across the diversity of environmental conditions in the state leads to a variety of issues for the durability of pavement. Currently, pavement aggregates are sourced from many local and regional aggregate vendors, and very little information exists regarding the mineralogy of pavement aggregates used throughout the state for paving projects. With increasing costs over recent years and decreasing pavement durability, it is essential to characterize the mineralogy of pavement aggregates in order to evaluate its durability. The purpose of this project is to characterize the mineralogy and texture of pavement aggregates from the primary aggregate sources currently in use by MaineDOT. These data will be used to investigate the relationship between pavement durability and the mineralogic properties of the source aggregates, in order to inform future decisions regarding pavement a1mregate sourcing.

Federal Highway Administration AB - This report details the completion of a 30-month project investigating wet-night and contrast pavement markings. The first-year report contains the literature review on wet-night markings and the Phase I effort on wet-night pavement markings. This report contains the Phase II effort on wet-night pavement markings, a benefit-cost analysis, and a study of contrast markings. Phase II effort consisted of expanding the study design from Phase I to include additional wet-night pavement marking products, the effects of glare and dry pavement on detection distances, and a benefit-cost analysis with respect to the use of different pavement marking systems to accommodate drivers under wet-night conditions. In the contrast study, a literature review of contrast markings, a state-of-the-practice with respect to contrast markings, and a study of driver understanding and preference with respect to contrast markings were all conducted. After studying multiple wet-night pavement marking products and standard pavement marking products used in the state of Texas, it was found that reflectorized raised pavement markings provided the most preview time under wet-night conditions. The rumble strip and the use of bigger beads such as Type III do provide improved wet-night detection distance, and in reference to cost, the use of bigger beads on a flat line, or a rumble strip in conjunction with RRPMs provides an effective wet-night performance. Contrast markings were found to be used in 64 percent of the districts in Texas and in 64 percent of the responding states. The most frequently used contrast marking design is the bordered design where a white marking is highlighted with black markings along the longitudinal sides. While driver preference suggests that the shadow design is less preferred to the bordered design, the shadow design is normally a more cost-effective design, considering maintenance of the marking. The findings show that the bordered design is preferred. While this design is currently provided with tape products, which have a high initial cost, a non-tape marking alternative is the shadow design, which has fewer maintenance concerns than other non-tape applications. The use of only these two designs is also recommended to limit the number of contrast marking designs in hopes of minimizing driver confusion (this study showed that some drivers do not understand the meaning of the contrast markings).

During the first year the emphasis was on determining the wet-night visibility of various pavement marking systems under a variety of realistic rainfall levels. The researchers performed a literature review. They analyzed 20 years of Texas rainfall data to determine the most appropriate rainfall levels to use as design criteria for a rain tunnel. Using a low, medium, and high rainfall rate (0.28, 0.52, and 0.87 in. per hour, respectively), a 1600 ft long rain tunnel was designed and built at Texas A&M University's Riverside Campus. Experimental subjects drove through the rain tunnel and looked for pavement markings simulating skip lines. The researchers rotated pavement marking samples at different locations before each trial. The detection distance was recorded when the subject located the pavement marking sample. The data were analyzed in four main sections: waterborne paints, thermoplastics, tapes, and exotic materials. The analysis also included investigations into the wet-night visibility of rumble stripes, as well as wider lines. The measured dry and wet retroreflectivity measurements were analyzed, and the predictive capabilities of the wet retroreflectivity measurements were evaluated with respect to the wet-night detection distance of the markings. During year two the researchers will supplement the detection distance data with additional data from a second round of wet-night visibility experiments. The researchers will also consider durability and cost information before finalizing the research. The researchers will also develop and implement research activities that can be used to develop application recommendations for contrast pavement marking materials based on visibility performance, durability, and cost.

By integrating these measurements into the USDOT Volpe Center MARINE-T decision support tool, researchers addressed substantial unpredicted variations in the original model, which was primarily trained on vessels in British Columbia. Using a derivative-free global search algorithm to iteratively tune five key model coefficients., the study achieved an average reduction in Root Mean Square Error (RMSE) of 4.5 dB across various vessel classes. While optimization significantly improved fit for large vessels like bulkers and tankers—particularly at low-frequency energy peaks—discrepancies remained for smaller or underrepresented categories like tugs, where operational modes (e.g., transiting versus active towing) drastically alter acoustic signatures. The findings underscore the necessity of expanding regional datasets and adopting multi-output modeling approaches to better capture the complex spectral characteristics of diverse global shipping fleets.

Federal Highway Administration AB - This report summarizes a statewide study commissioned by the Arizona Department of Transportation (ADOT) to inform and enhance anti-litter communications and operational litter remediation practices as they pertain to the Arizona state highway system. The project team conducted communications research, developed a highway visible litter characterization plan and tool, completed two seasonal field surveys (May and November 2023) at 60 randomized sites, analyzed litter composition and sources, identified litter hotspots, evaluated ADOT’s Adopt a Highway program impacts on litter and litter abatement costs, and estimated ADOT’s litter-related costs for FY2021–FY2024. Key findings include: an estimated 364.4 million pieces of litter on the SHS (38,452 pieces/mile on average), with small litter comprising 82.8% of items; tire tread dominated the inventory (173.5 million pieces; 47.6%), vehicle debris was the largest source (54%), motorists accounted for 33% of litter, and five interstate hotspots were identified. AAH volunteers contributed approximately 334,000 hours with an estimated four-year labor value of $2.5M and SHS sites that had approximately 50% less large litter than non-AAH sites. ADOT’s litter abatement costs averaged $8.8–$9.5M in FY2021–FY2024. The report provides targeted recommendations for litter communications, district-level litter collection operations, financial management, and procurement. Recommendations include data tracking, contract evaluation, staff engagement, targeted operational practices, and general and targeted anti-litter communication strategies all in an effort to reduce litter, improve cost tracking, and guide future litter program and communication development and evaluation.

This damage shortens the service life of transportation infrastructure and increases maintenance costs. To address this problem, this project explored the use of microencapsulated phase change materials (PCMs) in concrete. These materials can store and release heat as they freeze and melt. When temperatures drop, the PCMs release stored heat, helping to keep the concrete slightly warmer and reducing the number of freeze–thaw cycles that cause cracking and surface damage. A series of laboratory experiments was carried out to test different PCM types and amounts in concrete mixtures. The project also used machine learning tools to analyze the experimental data and predict how different PCM combinations would perform under various temperature conditions. The results showed that adding PCMs to concrete can significantly reduce freeze–thaw damage and improve long-term durability. The research provides a new, data-driven approach for designing more resilient and longer-lasting concrete for bridges and pavements in cold climates.

University Transportation Centers (UTC) Program AB - Monarch butterflies, ground-nesting bees and many other crucial pollinators depend on early succession grassland habitats for survival. In New England these habitats have been disappearing as agricultural lands are developed or allowed to mature into forest. Many of our native pollinator species are threatened or endangered. Highway clear zones and rights-of-way have become a primary source of early succession habitat. The linear nature of highways also facilitates connections and migration of pollinators between other sources of early succession habitat such as pollinator meadows, agricultural lands and natural areas. However, highway rights-of-way have not traditionally been managed as pollinator habitat. Limited access highways in New England and the Northeast were modeled after the parkways of the early 20th century, with their manicured lawns and carefully pruned ornamental plantings. In the intervening years landscape management intensity has decreased but mowed turfgrass remains the default ground cover. Establishment of pollinator plantings poses a challenge for managers of rights-of-way. Departments of transportation and the landscape installation companies they contract with are experienced at establishing cool-season turfgrasses using hydroseeding, and at establishing perennial forbs from container-grown transplants. However, they have little experience establishing native grasses and forbs from seed, and the lengthy pre- and post-seeding maintenance protocols recommended to minimize weed intrusion do not fit with existing project timelines. Selection of plant materials is also an issue as existing recommendations for roadside wildflower plantings come from outside of New England, and contain species or ecotypes that are not native in New England or not well adapted to New England soils and climate. Existing resources on establishment of pollinator plantings in New England are intended for homeowners, farmers or managers of natural areas and assume a very different set of management resources than what is available for highway rights-of-way. Finally, most of the available resources on roadside use of native plants do not include information on the pollinator benefits of the recommended species. This project addressed these knowledge gaps through three inter-connected tasks. A seed mix of regionally native grasses and insect-pollinated forbs was established using five different methods and then monitored for three years to identify effects of establishment method on the species composition of the resulting plant community. Twenty-six insect-pollinated forb species that are native to Rhode Island and have potential for use in roadside pollinator habitat were transplanted into the roadside environment and data were collected over two years on survival and growth. Existing lists of native species, of pollinator species, and of species suitable for the roadside environment were reviewed and combined to identify native woody plants that could be used in landscape plantings in highway rights-of-way to support pollinators during seasons when native forbs are not in flower. The project determined that broadcast seeding into plantable soil was the best method for establishing native forbs on roadsides, identified twelve species that are good candidates for inclusion in pollinator-friendly seed mixes for roadsides in Rhode Island and 14 species that should not be used, and created a guide to pollinator-friendly native woody plants for use by landscape architects in New England.

This study investigates the feasibility of using hydrated lime and carbon dioxide to form calcium carbonate binders that enhance the strength and stiffness of sands and silts. Elemental laboratory testing evaluated the influence of density, water content, degree of saturation, and gas mobility on carbonation rate and mechanical performance. Results show that substantial strength gains—comparable to cement-stabilized soils—can be achieved through carbonation, with optimal reaction rates occurring under partially saturated conditions that maintain a continuous gas phase. Large-scale soil box experiments demonstrated the scalability of surface carbonation and assessed durability under soaking and freeze–thaw cycling. Carbonated soils exhibited strong resistance to environmental degradation, retaining improved mechanical properties. Overall, the findings demonstrate that accelerated carbonation of lime-treated non-plastic soils is a promising approach with significant potential to reduce the carbon footprint associated with soil stabilization for transportation infrastructure. The next challenge will be to develop enablement schemes such that this technology can be deployed at scales relevant to civil infrastructure.
