Federal Aviation Administration AB - In fiscal year (FY) 2012, the Federal Aviation Administration (FAA) Office of Airports (ARP) initiated a research study to identify and geographically locate areas at airports with nonstandard taxiway geometry. This research was advanced because an earlier study had shown nonstandard taxiway geometries to be associated with a higher prevalence of runway incursions. The FAA defines a runway incursion (RI) as “any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for the landing and takeoff of aircraft.” These occurrences include wrong runway landings and takeoffs. This research effort developed a geographic information system (GIS) database of approximately 520 airports with civilian air traffic control towers. For each airport, the location of nonstandard geometries, runway incursions, airfield hot spot areas, airport diagrams, and other airport-related information is identified. This research study identified 140 airfield locations with a high incidence of RIs using data from October 1, 2007, to September 30, 2013. As a result, a long-term improvement program, known as the Runway Incursion Mitigation (RIM) program, launched in FY2015. The goal of the program was to mitigate airfield locations with high incidences of RIs. A subset of the 140 locations identified was then validated for inclusion in the RIM program and prioritized for mitigation.

Airport Engineering Division A4 - Flynn, Murphy AB - Construction Cycle 9 (CC9) was the ninth in a series of full-scale airport pavement tests performed at the Federal Aviation Administration (FAA) National Airport Pavement Test Facility, the fifth involving flexible pavements. It contained four test areas: fatigue, geosynthetics, cement-treated permeable base, and overload. This report addresses the geosynthetics test area, which consisted of two test items: LFC-3N with a geotextile separation fabric between the subgrade and subbase plus a Class B geogrid at the subbase/base interface, and LFC-3S with just the geotextile. These test items were subjected to simulated full-scale aircraft trafficking along with a control test item (LFC-4S) with similar materials and thickness but not containing geosynthetics. The goal of this test was to quantify any improvement in performance of the geosynthetic test items when compared to the control test item. Data were collected through laboratory and in situ testing, visual evaluation, and embedded pavement sensors. Researchers analyzed the effect of construction practices on pavement performance and compared pavement responses in all structural layers, in particular examining how the accumulation of permanent deformation is affected by the presence or absence of geogrid reinforcement and geotextile separation fabric. All three test items experienced structural failure before the end of traffic. Test items with geosynthetic elements had greater surface upheaval, rutting, and crack density than the control section; however, this was attributed to improper compaction of the sublayers during construction. The embedded sensors indicated that the geogrid increased the resistance to permanent deformation in the granular subbase layer. Despite accumulating higher surface rutting (attributed to the underlying compaction issues), the geogrid-reinforced test item LFC-3N exhibited lower upheaval than the other test items when trafficked beyond the pass where the failure criterion was met (1-in. dilative heave). The inclusion of geogrid aided in lateral confinement and resulted in lower permanent deformation in the subbase layer of LFC-3N than in the subbase layers of the LFC-3S and LFC-4S.

Office of Environment and Energy AB - An aircraft noise modeling framework is presented and used to perform a data-driven exploration of factors correlating with measured aircraft community noise and a model-based validation of the variables found to have the greatest noise impact. Aggregate departure and arrival noise and flight procedures were examined so that factors correlating with measured noise could be isolated. Operational flights at Seattle- Tacoma International Airport were examined using a framework that includes ADS-B data, a force balance kinematics model to estimate aircraft performance, and noise monitor recordings. Variation in measured noise within the network was examined as a function of observed data, including aircraft type, aircraft trajectory, airline, wind, temperature, and relative humidity; and inferred variables, including aircraft configuration, weight, and thrust. Airline-specific departure procedures were shown to impact noise measurements. Departure procedures with higher thrust and higher initial climb gradients were observed to have lower measured noise. Arrival procedures that delayed their deceleration were observed to have lower measured noise in some cases. Ambient environmental conditions, including wind, temperature, and relative humidity, were found to impact noise variation. A model-based evaluation of the factors correlating with aircraft noise followed the data-driven exploration. The delayed deceleration approach, a procedure in which aircraft maintain higher speeds, remain cleanly configured, and fly with lower thrust levels for a longer period of time, was identified as having noise reduction potential beyond 8 nm from the airport. Noise from operational Boeing 737, Airbus A320, and Embraer E190 flights at Boston Logan and Seattle Tacoma airports was modeled using the NASA Airplane Noise Prediction Program and was compared with ground noise monitor measurements. When corrected for atmospheric conditions, modeled noise results were consistent with noise monitor readings under reasonable flap deployment assumptions during various early, intermediate, and delayed deceleration approach procedures. Measured noise results indicated that compared to aircraft that decelerated early, aircraft performing delayed deceleration approaches reduced noise by an average of 3-6 dB across different aircraft types.

Office of Environment and Energy AB - Traditional airport noise modeling is limited in its ability to analyze large quantities of flight tracks due to high computation time. As a result, yearly noise reports are often limited to modeling flights from a single “representative day,” which lacks detail arising from the natural dispersion of flight tracks and variety in airport operations occurring throughout an entire year of operations. AB - A framework for processing actual flight data and applying an existing, fast noise approximation is presented. Tens of thousands of flights can be analyzed in a matter of hours, allowing for a data-comprehensive approach to calculating noise metrics. Method results are cross-validated against the Aviation Environmental Design Tool (AEDT) on a single-event basis and an existing aggregate result on a multi-event basis. AB - Results for a variety of metrics are presented based on data sourced from Boston Logan International Airport in 2016.

Here, we describe the Global SAF Capacity Database to quantify global and European Union (EU) SAF capacity, comparing it to production capacity announcements. Despite announcements of 9.1 Mt year−1 (2.2 Mt year−1 in the EU) by 2024 and 38.9 Mt year−1 (9.3 Mt year−1 in the EU) by 2030, only 24% (26% in the EU) of the announced capacity was realized on time by 2024. Over 40% of the announced capacity for 2030 risks delays or cancellations. Using a diffusion model parametrized by announced capacity, realization rates, expected demand, and historical growth analogs, we calculate SAF potential scale-up to meet net-zero carbon emissions by 2050. Even if SAF follows the rapid scale-up of solar and wind energy, the global and EU capacity will fall short of respective targets by 42% and 18% in 2030, and 7% and 5% in 2050.

Office of Environment and Energy AB - Replacing conventional aviation fuel (CAF) with sustainable aviation fuel (SAF) has been suggested as a vital means to decarbonize the aviation industry. We considered winter canola a feedstock for SAF production through the hydro-processed esters and fatty acids pathway in the Southeast United States. We incorporated feedstock yield variations in a stochastic mixed-integer linear programming model to optimize the SAF supply chain. Results suggest the potential SAF production for Nashville International Airport (BNA), from an existing oil extraction mill and 0.19 million hectares (ha) of winter canola cultivation, range from 129 million liters yearly (MLY) to 246 MLY with a 90 % likelihood. With additional investment and expanded winter canola cultivation to 0.61 million ha, the expected SAF supply to BNA could increase to 348 MLY. An additional 212 MLY can be supplied to Memphis International Airport. After considering the co-product revenues, the expected breakeven cost for SAF is $1.1 per liter. The SAF's carbon intensity falls into the range from 31 g of carbon dioxide equivalent per megajoule of fuel (g CO2e MJ?? 1) to 43 g CO2e MJ?? 1, with 90 % probability, which is at least 50 % lower than CAF.

Federal Highway Administration AB - Improving commercial vehicle safety continues to be an important priority for all stakeholders. There has been considerable focus in Indiana on reducing work zone related crashes, particularly those involving commercial motor vehicles encountering unexpected slowdowns or stopped traffic on the interstate. Connected vehicle data have the potential to warn motorists of impending slowdowns and congestion in real-time. Multiple data providers have recently begun providing in-cab alerts to commercial vehicle drivers in areas of congestion, dangerous slowdowns, and work zone construction to increase driver awareness of potential hazards. This research utilized 1-second frequency data from trucks receiving in-cab alerts for Congestion or Dangerous Slowdown incidents on limited access roadways in Indiana to analyze the impact of these alerts on commercial vehicle driver behavior from about 30 seconds prior up to 5 minutes after an alert was received. Analysis of approximately 20,000 in-cab alerts sent to commercial vehicle drivers along 44 limited access corridors in Indiana for the months of April–June 2024 showed that 21.2% of drivers receiving a Dangerous Slowdown alert and 15% of drivers receiving a Congestion alert had reduced their speeds by at least 5 mph within 30 s of receiving an alert. As this area of in-cab alerts continues to evolve, it will be important to converge on a shared vision and common targets for these safety and mobility performance measures so that public agencies, in-cab alert providers, and trucking companies can work closely together to agilely improve these systems and increase driver confidence.

Office of Environment and Energy AB - Given the high level of uncertainty prevalent in the immature biofuels industry, the primary objective of this study was to identify and assess the risk factors that biofuel firms face. The study evaluated the risk factors, or specific risks, reported by biofuel firms to the U.S. Securities and Exchange Commission (SEC) over five years. The analysis was conducted for all firms in the sample, as well as for subsets of focused and diversified biofuel firms. Based on a biofuels industry risk structure derived from previous research, we coded and analyzed 4310 risk narrative disclosures, extracts from firms’ annual reports filed with the SEC. The study evaluated two risk metrics—prevalence and relevance—across 25 specific risks. Risk relevance, the most comprehensive metric, was validated by comparing it with two widely used risk metrics—which measure overall firm risk rather than specific risks—, the Z-score and the debt-to-equity ratio. Identification of risk metrics by quadrants, combined with quantile regression analysis, allowed us to identify the critical risks in the biofuels industry. The critical risks, particularly for focused biofuel firms, were biofuel regulation, biofuel markets, feedstock markets, conversion technologies, profitable operations, financing, and risk management. To a lesser extent, environmental and contracting risks were critical. The results of this study can guide policymakers and firm managers in developing a compelling policy mix and strategies to address the challenges faced by the biofuels industry.

Office of Environment and Energy AB - Transitioning to alternative energy carriers is one of the primary options for reducing greenhouse gas emissions attributable to transportation. In the US, ethanol from corn grain covers 10.5% of gasoline demand from road transport today. Its production could be scaled-up further to also make sustainable aviation fuel. Additionally, the biogenic CO2 produced during fermentation could provide an option for carbon removal or for additional fuel production. In this study, we investigate the economic and environmental impacts of using the CO2 from ethanol fermentation either through capturing and sequestering the CO2 (CCS) or through the production of electrofuels (CCU), via fischer-tropsch and methanol-to-jet as conversion technologies. We find that CCS can increase the total offset CO2 by 135% compared to ethanol-to-jet plants while increasing the minimum selling price (MSP) of the produced biofuel by 5-7%. Comparatively, there is significant variation in the results for CCU pathways, increasing the total offset CO2 by 90 - 205%; however, the MSP of the electrofuels produced is 36 – 218% higher than the biofuels produced. This study highlights the trade-offs between fuel carbon intensity, costs, production volumes and output fuel mix for renewable fuel facilities, with the optimal configuration being dependent on the project's primary objectives.

Federal Aviation Administration. Office of Environment and Energy AB - Policymakers and the aviation industry are working to decarbonize commercial flights by replacing conventional jet fuel with sustainable aviation fuel (SAF). Logging residues have been identified as a valuable resource for SAF production. However, the quality of the feedstock, particularly the ash content, can adversely affect bio-oil yield and SAF production using the fast pyrolysis/hydrotreatment process, and potentially its supply chain optimization. Previous research often assumes fixed biofuel yields and neglects the variability in feedstock quality when optimizing the supply chain. Thus, this study seeks to address this gap in the literature by employing a two-stage mixed-integer linear programming (MILP) model to investigate the influence of varying ash content in logging residues on the potential maximum supply quantity (MSQ) and net revenue (NR) of SAF production. Two scenarios were conducted in the Southeastern United States (US): one assuming constant ash content and the other accounting for heterogeneous ash content in logging residues. Results indicate that ignoring ash variability in the feedstock could lead to overestimation of SAF MSQ and NR by 14.15 % and 18.27 %, respectively, in the study area. Additionally, higher ash content leads to lower bio-oil yields, resulting in fewer refineries and reduced capacity. The study emphasizes the need for best management practices to mitigate soil contamination during feedstock processing and improve the resilience of the biomass-based SAF supply chain. Furthermore, it is crucial to effectively manage the mechanisms of mineral uptake and their integration into the structure of lignocellulosic materials.

Federal Highway Administration AB - Warning signs are typically deployed at bridges to warn motorists of potential icy surface conditions on the bridge, although the effectiveness of these signs is questionable. One potential improvement is the bridge deck warning system (BDWS), which activates a flashing warning sign border or beacon based on real-time weather and bridge surface data. However, such systems have not been broadly implemented, and consequently, their effectiveness as a safety countermeasure is not well established. To address this knowledge gap, research was performed to evaluate BDWS strategies in terms of their impacts on driver behavior and safety performance during winter driving conditions, and to provide guidance to support future deployments of BDWS within Michigan. A series of winter field evaluations were performed along three freeway bridges in Michigan to assess the effectiveness of various BDWS strategies as a speed reduction countermeasure for motorists approaching a potentially icy bridge. The results showed that a BDWS with a flashing LED border reduced motorist speeds when encountering a bridge during winter weather conditions compared to the standard MUTCD W8-13 warning sign, and this effect was consistent between passenger cars and heavy trucks. Greater speed reductions were observed when the BDWS sign was combined with a dynamic speed feedback (DSFS) sign that displayed a “SLOWDOWN” or “ICY ROAD” message to approaching motorists, with the strongest effects observed when the message was pulsed at 1hertz. Speed reductions were also observed when a “SLIPPERY ROAD CONDITIONS / REDUCE SPEEDS” message was displayed on a full-size DMS located at the subject bridge. A preliminary analysis of crashes before and after installation of the current BDWS implementations in Michigan found that winter-season target crash frequencies were lower at 16 of the 20 sites after installation of the BDWS. Collectively, the findings of this research suggest that BDWS help improve driver behavior and safety performance at bridges during winter driving conditions in Michigan, and continued implementation and operation of BDWS is recommended. The research findings were utilized to develop guidelines and recommendations towards future implementation and operation of BDWS in Michigan, including selection of sites, sign types, warning alerts and messages, sensors and related equipment.

Department of Transportation. Federal Highway Administration AB - Montana’s timber bridge inventory includes over 600 state and county owned bridges, many more than 80 years old and showing visible deterioration. Traditional girder repair methods, such as steel hangers and timber or steel sister girders, are heavy, labor-intensive, and often lack well-documented performance verification. Fiber-reinforced polymer (FRP) composites offer a light weight, corrosion-resistant alternative with strong potential for timber bridge rehabilitation, yet their application to timber bridges remains relatively underexplored, particularly at full scale and under field conditions. This report investigates the use of pultruded FRP composites to repair and strengthen deteriorated timber bridge girders to restore capacity and extend service life. Full-scale laboratory testing was conducted on 22 salvaged Douglas-fir/Larch beams from bridges across Montana. Beams were categorized as control, repaired (with pre-existing or induced splits and cracks), or strengthened (intact), and retrofitted using carbon–glass hybrid strips, glass FRP channels, or a combination of both. The channel–strip configuration showed the most robust performance, increasing moment capacity significantly compared to control specimens, while strip-only repairs also improved performance, particularly for moderately damaged beams. To validate the laboratory findings, selected FRP repair techniques were implemented on two in-service timber bridges near Toston, Montana. Installation was completed rapidly using standard tools, demonstrating the constructability of the repair systems under field conditions. A seven-month follow-up inspection indicated no visible deterioration or issues. Overall, this work provides a validated, field-tested approach for rehabilitating timber bridge girders using pultruded FRP composites, offering transportation agencies a practical strategy to extend the service life of aging timber infrastructure.

The A320 mistakenly aligned with the taxiway instead of the parallel runway on which they were cleared to land. Because of this incident, the National Transportation Safety Board (NTSB) made a safety recommendation to improve the conspicuity of closed runways, particularly under nighttime conditions when at least one parallel runway remains in use. The Federal Aviation Administration (FAA) Office of Airports tasked the National Institute of Standards and Technology (NIST) to evaluate different configurations of Lighted X (LX) systems. NIST’s laboratory experiments with pilot participants revealed that larger 28-foot LX configurations were more recognizable from greater distances. However, the findings needed validation through real-world flight testing in varied lighting conditions to confirm their practical applicability. The FAA Airport Technology Research and Development (ATR) Branch conducted research to test and evaluate LX runway closure markers (RCMs) in real-world scenarios to validate NIST’s laboratory results. Eighty-eight test configurations were considered to evaluate the optimal intensity, size, and flash rate of the RCMs. Given this large test set and the costs associated with conducting flight testing, ATR conducted a two-phase test approach: ground tests at the Lakehurst Naval Air Warfare Center Aircraft Division (NAWCAD) and flight tests at Cape May Airport (WWD). Results from ground observations were used to eliminate RCM configurations that pilots found least viable, leading to a reduction from 88 test configurations to 33 based on pilot feedback. This report focuses on the results gathered from Phase 2 and provides a comprehensive summary of flight testing and recommends optimal LX configurations for intensity, size, and flash rate to better signal runway closures to pilots during operations.

Federal Aviation Administration. Office of Aviation Research AB - The number of inadvertent runway incursions has grown during recent years, increasing the importance of protective visual guidance systems for incursion prevention. One such visual system is the L-804 elevated runway guard light fixture. Also known as a wig-wag light, these fixtures contain two alternately flashing yellow lights and are used to help identify runway holding positions to pilots. Pilots, however, have indicated that the light intensity (600 candelas minimum average intensity) and flash rate (average of 35 flashes per minute per lamp) of the L-804s are inadequate. The L-804s were examined under day and night visual flight rules (VFR) and instrument flight rules (IFR) conditions from various distances and angles. Particular attention was paid to performance characteristics such as intensity, flash rate, vertical and horizontal aiming angle, lamp separation, and the usefulness of providing a hood over each lamp. As a result of the evaluation it was determined that the L-804 specifications needed to be modified. Flash rate should be increased to 45 to 50 flashes per minute per lamp. The light intensity of the Mode I (constant current) L-804 when energized at 6.6 amps and tested with one lamp in the steady burning mode and the other lamp masked out should be 4100 candelas. The light intensity of the Mode 2 (constant voltage) L-804 when energized at 120 volts and similarly tested should be 940 candelas.

Building on an AI-based video pipeline from previous research, empirical non-motorist counts from 18 rail crossings in Lincoln, Nebraska, were used to calibrate a regression model that predicted daily pedestrian and bicycle traffic volumes at 13,672 public rail crossings in Nebraska, Kansas, Missouri, and Iowa. These traffic volume predictions were integrated into a modified Accident Prediction and Severity (APS) framework using a Zero-Inflated Negative Binomial (ZINB) model, showing an average of 5.5% increase in predicted crashes and much larger increases at crossings with substantial non-motorist traffic. A two-stage AI approach, Random Forest classification followed by Random Forest regression, further improved predictive performance relative to the ZINB and provided a practical tool for screening and prioritizing high-risk rail crossings. The findings demonstrate that non-motorist traffic is a critical but previously underrepresented factor in rail crossing safety assessment and support a scalable, data-driven framework for multimodal safety management.

The DC-9 was gutted from a fire believed to have originated in the vicinity of this lavatory pump motor. The ramp fire started after power up in Barranquilla, Columbia. The National Transportation Safety Board requested the FAA to identify the pump motor housing components to assist the investigation of the incident. The flammability of the identified pump motor housing components was reviewed. The acetal copolymer, the principal component, is known to sustain continued combustion in the presence of a small ignition source and may have contributed to the spread of the fire. Acetal polymers may not be an appropriate fire-safe material for this application.

Federal Aviation Administration. Office of Aviation. Office of NextGen AB - The Federal Aviation Administration’s air traffic control organization (ATO) encompasses a variety of facilities that include towers, terminal radar approach control facilities (TRACONs), and air route traffic control centers (ARTCCs). Air traffic controllers use alarms, alerts, and warnings (collectively, signals) as an aid to situation awareness and to reduce cognitive workload. We have written a handbook that offers guidance for the creation or modification of air traffic control system alarms, alerts, and warnings using a process that encourages collaboration between controllers, system designers and human factors experts. The novel Signal Design Framework described in this handbook uses a structured interview with operational subject matter experts (i.e., air traffic controllers) and an objective scoring sheet to develop a series of specifications that can be used to modify an existing signal or design a new signal. This framework provides a common language that subject matter experts, system designers, and engineers can use to describe, classify, and objectively evaluate signals. We tested and validated the Signal Design Framework and its associated structured interview during Phase 4 when we developed a new microburst alarm and a trajectory conformance alarm. This project provides the ATO with the tools to develop signals to keep the United States’ National Airspace System the safest in the world.

Federal Highway Administration AB - This research proposes a framework for assessing the impacts of new and existing cycling infrastructure using minimum impedance routing. Impedance represents the relative difficulty of cycling taking into consideration travel time, exposure to automobiles, hills, and the provision of cycling infrastructure. An all-paths network is created from OpenStreetMap data, and data on traffic volumes, vehicle speeds, the number of vehicle lanes, elevation, and bicycle facilities are reconciled with the all-paths network. Map-matched cycling GPS traces from the Cycle Atlanta app are cleaned and then used to calibrate link and turn impedance functions that consider cyclists’ preferences for link and turn attributes. The calibration process uses stochastic optimization techniques to maximize the overlap between the map-matched and impedance paths. The calibrated link and turn impedance functions are then applied to the 250 square mile metro Atlanta study area to assess the impact of 38 planned bicycle facilities for 3.6 million trips from the Atlanta Regional Commission Activity Based Model. Both the minimum travel time and impedance paths are calculated for the existing network and compared against the minimum impedance paths for the future network with the planned bicycle facilities. The results were then processed to create metrics and visuals on trip impedance reduction, percent detour, change in link betweenness centrality, impedance reduction contribution, and bike sheds. The calibrated impedance factors and framework are then applied to Savannah, GA to assess the impacts of 57 proposed bicycle facilities. This demonstrated that the framework and calibrated impedance factors could likely be used throughout the state of Georgia to assist GDOT, MPOs, and cities in assessing and prioritizing cycling infrastructure projects.

This loss of capacity often leads to major safety risks, network disruptions, and high economic impacts. A curated history of U.S. bridge fires in the 20th and 21st centuries is presented. This history identifies recurring ignition sources, contributing factors, and damage patterns associated with bridge fires. The research team further synthesizes current knowledge on critical temperatures and heat-induced defects in steel and concrete. They evaluate rapid nondestructive testing (NDT) methods that can be used for a post-fire triage inspection. Integrating the historical case studies, common trends found in the historical record of bridge fires, material behavior, and NDT information, the team presents practical guidance to support post-fire triage of highway bridges. In addition, they propose a methodology that may be implemented to develop a single, easy-to-use universal model to determine the residual structural capacity of fire damaged concrete. Laboratory burn testing of concrete samples was conducted to quantify residual compressive strength as a function of changes in rebound hammer values and ultrasonic pulse velocity. During testing, the model produced a standard error of 8 percent for estimating residual compressive strength. This indicates promise for refinement with further testing. A three-factor model that incorporated visual cues was also developed. The three-factor model improved overall fit but raised concerns about robustness and practical reliability. The report concludes with recommendations for post-fire inspection procedures, expanded training for bridge and maintenance personnel, and wider availability of NDT equipment to support timely, consistent, and defensible triage decision following bridge fires.

The research integrates laboratory calibration and field validation for two widely used stabilization practices: conventional soil-cement stabilization and full-depth reclamation (FDR). Laboratory work involved preparing soil-cement/FDR specimens with varying cement and moisture contents, compacted to field-representative densities. The specimens were tested daily for over an 8-day curing period using dielectric constant and electrical conductivity measurements to track the hydration process. A field GPR survey was conducted at several GDOT project sites in Albany, Conyers, and Peachtree City, as well as Henry County, using a 2-GHz air-coupled antenna. Dielectric constants were obtained from GPR scans, and electrical conductivity was derived through the Crockford et al. (2021) model. Cement content estimation was performed by matching the field electrical conductivity values to the corresponding laboratory-derived surfaces. The estimated cement content at the soil-cement and FDR sites ranged between 4 and 7 percent. Although some sites showed results consistent with the running average, others exhibited estimated cement contents exceeding or falling below the design mix, indicating non-uniform cement application across the sites. These findings highlight the importance of developing a reliable quality control and quality assurance framework to ensure consistent and verifiable material performance in the field.

Results show that summer rainfall events with precipitation ≥ 0.5 inches produced short-term temperature increases at Sites 1 and 2, with Site 1 (Chattahoochee River) exhibiting brief exceedances above the 2 °F limit for secondary trout waters. Site 2 (Powder Springs Creek) displayed smaller rises that rarely approached the threshold, while Site 3 (Two-Run Creek) showed no measurable temperature increase under any rainfall conditions. DO reductions tracked temperature inversely but remained within regulatory limits after artifact screening. All impacts were event-specific and recovered within hours. The project establishes a scalable monitoring framework that can be applicable nationwide and provides site-specific BMP guidance to strengthen GDOT’s MS4 Permit compliance and protect sensitive secondary trout streams.

Federal Highway Administration AB - The well-known bump-at-the-end-of-the-bridge often involving the joint between a bridge approach slab (BAS) and a bridge deck (as well as the associated slab cracking) has been a recurring issue over the years in many states. DOTs have reported differential settlement and cracking issues at this joint which has significantly reduced ride quality. Previous experience indicates that any “non-removal” conventional method of repair would not work well once erosion has set in; however, removing and replacing distressed BAS with cast-in-place (CIP) concrete usually require significant amount of time for curing, which leads to high costs of lane-closure and user delays. Therefore, a long-lasting and rapid repair method is needed to address this issue. This research focuses in part on the introduction of the precast concrete pavement slab for repairing distressed BASs and the elaboration of the design and construction procedures for precast BASs. Key elements within a BAS system are identified and design considerations provided for these elements for the prevention of erosion damage that may occur underneath the BASs. In addition, this research also provides a detailed design procedure for the stone column technique in order to address the potential for large settlement in the foundation of bridge embankments and proposes a procedure using non-destructive testing methods to rapidly characterize soil properties. This report contains three parts. The first part, “Final Report”, consists of Chapter 1 through Appendix D; the second part, from Chapter 9 to Appendix H, is the “Bridge Approach Design Guideline”; the third part is the “Stone Column and Embankment Design Guideline” which consists of Chapter 14 to Appendix N.

It differed from the first on in that it contained wax beads only in the top two inches as opposed to full depth and it covered the entire deck instead of just one span. The objective of this study was to gain experience in placing and heating a wax impregnated concrete bridge deck ion a full-scale basis. Work was performed on an existing Interstate bridge that needed widening and redecking. The bridge's maintenance history is included in the report. The project design and construction phases are described in detail. The deck was placed with two pours instead of a monolithic pour as originally planned. A petrographic classification was made of the aggregates. The mix design detailing the conversion from conventional bridge deck concrete to wax bead concrete is explained. A trial mix was made prior to pouring the wax bead overlay to insure good bead distribution. The heat blankets and heat treating method used to internally seal the deck are described. Tests to determine the effectiveness of the wax seal the deck are described. Tests to determine the effectiveness of the wax seal are discussed. These included: (1) A "before" and "after" heating crack survey, (2) 24 hour absorption, (3) dye penetration, (4) skid resistance, (5) half-cell potential, (6) compressive and flexural strength, and (7) a chloride analysis. All of the test showed good results. This method deserves serious consideration in the bridge design process.

The measurements were to be made during daylight hours and from a moving vehicle. A practical field device, or instrument, was then to be designed and developed. During the course of the project, one major change was made in the objective. This was to measure the contrast of the stripe to its background rather than stripe luminance only. A bench prototype of the optical system and the servo controlled tracking system has been constructed and tested in the laboratory. This report discusses the system requirements, the design approaches considered, the prototype tracking system and the proposed design of the complete device.

A total of 15 unique microsimulation models were developed and run three times each to test three case studies of bi-direction bandwidth optimization, cycle length sensitivity, and leading pedestrian interval sensitivity. Results show that optimization can improve overall corridor operation, and that all approaches and turning movements must be evaluated. Specific improvements can be targeted using shorter cycle lengths, but cycle length reaches a point where diminishing returns are experienced. Leading Pedestrian Intervals can provide safety improvements for pedestrians, but the effects are influenced by the optimization strategies.

More than 2 million of these visitors will explore the World Wide Web to learn more about their destination prior to their trip. For this reason, the Federal Highway Administration, in partnership with the Arizona Department of Transportation (DOT), sponsored the development of the AZ TripUSA™ Rural Model Deployment Initiative (MDI)/Field Operation Test (FOT) in Northern Arizona along I-40. The result was TripUSA™ (developed by Castle Rock Consultants). This program is a public/private partnership created to improve traveler mobility, enhance economic development for the area, and enrich the overall experience of travelers. AZ TripUSA™ was successfully deployed during the first 6 months of 1998. TripUSA™ allows travelers who use the Internet to discover a wealth of information about their destination for use in trip and travel planning. Upon arriving at their destination, travelers can use interactive touch-screen kiosks to check road and weather conditions, find lodging and restaurants, and obtain directions to attractions.

Branson attracts more than 6 million visitors per year. The congestion on State Highway 76 is severe (Level of Service F) during peak and some off-peak periods. The lack of right-of-way makes it impossible for the city to "build" out of its congestion problems. With this in mind, the Branson Travel and Recreational Information Program (TR IP) project was created. The Branson TRIP project was one of five Advanced Rural Transportation System Operational Tests selected in August 1997 by the Federal Highway Administration for deployment. The Branson area provided an excellent opportunity to test Advanced Traveler Information System (ATIS) technologies in a rural tourist destination.

More fundamental, theoretical studies concerning basic issues of human perception, cognition, and motor functions as related to the driving task also are performed here. The HFL staff explores critical human factors issues within the broader context of FHWA's research programs. Small-scale studies typically provide (1) information to adequately define the objectives and scope of subsequent larger research efforts; (2) recommendations--through the FHWA Office of Traffic Operations--to the National Committee on Uniform Traffic Control Devices for additions, deletions, and changes to the Manual on Uniform Traffic Control Devices; and (3) data for staff research reports on a variety of transportation related research issues.

In response, a multi-year research effort developed the prototype, open-source Travel Risk In Pandemics (TRIP-X) simulation model to extend FAA Order 8040.4 Safety Risk Management principles to respiratory and biological hazards in air travel. TRIP-X integrates ventilation, human behavior, operational, and microbiological factors using airport and aircraft data to quantify transmission risk, evaluate layered controls, and support evidence-based decision-making. Beyond pandemic preparedness, TRIP-X enables tailored protective strategies for repatriation and humanitarian operations—such as safely evacuating personnel during Ebola or other severe outbreaks without imposing unnecessary restrictions—while also optimizing outbreak and epidemic management to balance public-health protection with the continuity of air travel, commerce, and societal mobility. Additionally, it supports homeland security and threat preparedness by providing a framework for structured threat and vulnerability analyses of intentional biological releases, strengthening aviation safety, public-health coordination, and national defense readiness under a unified risk-management approach.

When pavement deteriorates, it can lead to safety hazards, higher vehicle maintenance costs, and expensive repairs for cities and states—making early detection essential for everyone who relies on the roadway system. To address this challenge, the research team developed a prototype cracking identification system that integrates a customized machine learning model with computer vision algorithms. High-resolution images collected from drones or ground-based cameras are processed within the system to automatically detect and classify major cracking types. The core of the framework utilizes the You Only Look Once (YOLO) architecture, which enables fast detection and accurate localization of cracking distresses. Experimental results demonstrate that the model achieves over 80% accuracy across multiple crack categories. In addition to detection efficiency, the system emphasizes usability, providing an effective tool for transportation agencies to support pavement evaluation and management. This innovative approach represents a step toward more automated, reliable, and scalable pavement condition assessment, which supports safer, more cost-effective transportation systems.

CPTED principles aim to reduce the chances and fear of criminal activity by designing spaces that both deter criminal activity and build community. Notably, public transportation can be an attractor of crime, and safety is cited as one barrier to public transportation. The goal of this work is to identify opportunities to integrate CPTED into transit station design to improve perceptions of safety for riders and increase transit access. To accomplish this goal, the project team catalogued CPTED practices already in use by a local transit agency, even if they were employed outside of an explicit CPTED framework. The team also assessed CPTED features in place at eleven transit stops. A limited rider survey was also conducted. Based on findings to date, the team identifies additional options for applying CPTED in public transit.
