Office of Bridges and Structures AB - Tied arch bridges represent a vital component of the nation's infrastructure, valued for their structural efficiency and aesthetic qualities. These bridges rely on arch ribs to transfer vertical loads into horizontal thrusts, which are counteracted by the tie beams (TBs) acting in axial tension. In addition to this axial tension, TBs are also subjected to strong axis bending mainly due to live loads from vehicular traffic. The TB, therefore, is a critical structural component, maintaining the internal equilibrium of the system by resisting the spreading forces generated by the arch and bending caused by the moving vehicular loads. These TBs are often constructed as built-up steel members, a design that inherently possesses a degree of internal redundancy, allowing them to redistribute loads among their components following a localized fracture.

Sensor degradation refers to the gradual decline in a sensor’s performance over time, resulting in deviations from its nominal or expected output. The scope included permanent and semi-permanent cumulative degradations affecting camera, radar, and LiDAR sensors. Degradation types were identified through a literature review and stakeholder interviews. Methods were developed to create, test, and evaluate degradations using static tests with various targets, enabling consistent assessment of different material and degradation combinations. Results helped identify the most impactful degradations and guided the selection of samples for component and vehicle-level testing. Each degradation was tested at three severity levels (high, medium, and low). Camera, radar, and LiDAR sensors and a ground truth system were mounted on a vehicle for data collection in dynamic scenarios using a target vehicle. Sensor data with and without degraded conditions were compared. While all degradations affected sensor signal paths, impacts varied. Occlusions reduced sensor response, and road grime or improper repairs significantly decreased sensor range and point returns. System level evaluation of a vehicle’s ADAS with degraded sensors introduced additional challenges. Depending on how the ADAS processed degraded sensor signals and the level of redundancy (e.g., sensor fusion), system behavior ranged from feature shutdown, to ADAS performance degradation, or no impact.

Following earlier trials, we report the design, justification, roll out and early results of Total Friction Management (TFM) (GF plus TOR) over all high tonnage lines in Western Canada. Tools and processes needed for implementing TFM over a large territory are described. The roll out incorporates state of the art equipment and materials for GF and TOR application, logistics considerations for material handling, and maintenance issues through dedicated TFM staff. Development of a holistic economic case for this TFM project is discussed. Prior results were used to quantify expected savings in rail, ties, and track regauging. Wheel replacement savings were estimated. Locomotive fuel savings were projected by model. Together with the appropriate costs, the expected savings were used to develop an overall business case. TFM implementation involves installation of 325 TOR wayside applicators over 923 route miles between Calgary to Vancouver, as well as optimization and upgrade of 216 wayside GF units. Remote Performance Monitoring is used to manage unit maintenance. Performance verification includes use of L/V sites for TOR effectiveness, and regular high speed tribometer runs to validate and optimize GF performance. Monitoring of the project to date indicate fuel savings (>5%) well in excess of those used to justify the project.

To generate the explanatory variable, the concept of Inertial Tractive Effort (ITE) was developed. Given the total instantaneous tractive effort (TE) dispatched by a locomotive consist to overcome all sources of resistance, ITE is an estimate of the portion spent overcoming inertial resistance to generate acceleration. Integrating ITE over time yields cumulative ITE (cITE), which is in essence an estimate of total energy spent on acceleration versus a train travelling at constant speed over the same territory. Analysis of data collected in revenue service on several Union Pacific coal routes has shown that cITE acts as an explanatory variable, effectively mitigating variability in the data and allowing for an improved confidence when analyzing the impacts of other variables such as TORFM application. With the incorporation of cITE as an explanatory variable in a multi-variable regression of locomotive fuel data collected over five months of revenue service operation on Union Pacific, the statistical power of the underlying model was improved to yield a P-value of 0.028 versus 0.202 otherwise (the corresponding fuel savings associated with TORFM application were estimated at 6.4%). The approach represents a novel and useful mechanism to handle fuel data variability, with the potential to underpin a broad range of analyses. AB - Please cite: Oldknow, K., et al.

Traditionally, the preferred method of FM application has been trackside systems. However, in some situations, it is desirable that friction modifiers are applied from on-board a train set due to several different factors. Recently, Shuohaung Railroad have installed three (3) prototype on-board TOR dispensing systems on their SS4B locomotives and have been successfully operating them for the last three years. Field testing, conducted by the Chinese Academy of Rail Sciences, have demonstrated energy savings of approximately 5 %, lateral force reductions of 10-20 %, and following train benefits for non-TOR equipped train sets. Simple cost benefit analysis modelling is shown to favour on-board FM application over trackside FM application. AB - Please cite as: Cotter, J., et al.

The spray application system is mounted on a revenue-generating freight car located immediately behind the trailing locomotive. Compared with locomotive mounted systems [1, 2, 3], the new approach provides higher capital utilization, no impact on locomotive maintenance scheduling, and a simple but robust system. A prototype system has been successfully designed, installed, & field-tested on a revenue-generating ore car at QCM’s facility in Port Cartier, Quebec. As well as equipment performance, results are also described on lateral force reduction. AB - Please cite as: Cotter, J., et al.

In these areas disruptions to regular traffic flow are inevitable and the safety of road users and highway workers is a major concern. In the U.S. for the past five years from 2002-2006, there were nearly 5,406 fatalities occurring in or near work zones. Among other reasons, this may be partly due to ineffective implementation of preventive measures at work zones and shows that more effort must be made in order to improve safety in work zones for both highway users and workers.

Institute for Transportation AB - Safety in highway work zones has been a major concern for many decades. Over the years, government agencies and highway industry have developed work zone safety training programs to educate general public, professionals, and government employers. Existing training programs are conducted in the old fashion classroom setting which has some disadvantages such as high travel costs and locations far away from jobs. The objective of this research project was to develop a web-based training program for highway work zone safety. The developed program was built on advanced computer science technologies and delivered via Internet so that a trainee can access the training materials at any time and at any location as long as there is an Internet service. Training topics cover sign, marking, highway traffic signal, and temporary traffic control. At the end of training, a trainee will have an opportunity to take an on-line quiz with 50 questions. A certificate will be sent to the trainee via e-mail if that person’s test score is higher than the passing grade. The developed web-based training program has several advantages. First, using the developed program will eliminate the travel costs for the instructors and trainees. Second, both the instructors and trainees will spend less time away from their jobs. Third, the developed program can be easily modified and updated with any new information. Finally, trainees can learn the training materials at their own pace. The self pace format can be easily fitted in a busy working schedule.

There are two distinct forms of capacity depending upon the flow regime: capacity while traffic is free flowing and capacity while traffic is queued. Actual work zones from the Milwaukee freeway systems were varied by simulation to obtain relationships between capacity and truck volume, lane distribution, ramp location, ramp volumes, grade and merging schemes. Capacity was found to be a random variable, even when all prevailing conditions are held constant, because of stochastic variations in vehicle mix, lane distribution and driver behavior. Capacity was found to be significantly affected by prevailing conditions of grade, vehicle mix, and the lane distribution of trucks.

TY - Journal Article AU - Driscoll, Thomas M AU - Sakhare, Rahul Suryakant AU - Desai, Jairaj AU - Bullock, Darcy M. A2 - Purdue University. Lyles Department of Civil Engineering AB - Most state agencies have good practices for monitoring congestion on roadways within their jurisdiction. Many urbanized areas span state boundaries, where incidents, work zones, and congestion often impact neighboring states or municipalities. States with urbanized borders that experience congestion often develop informal communication procedures and occasionally share a few traffic management cameras. However, system integration to share between adjacent states can be challenging, particularly for work zones and incidents. Commercial connected vehicle data (CV) provides real-time probes for corridors and can be used to monitor traffic data either within a state or across the border into an adjacent state with no requirement for institutional interfaces. For example, Indiana has 15 interstate crossings into four different states. As a matter of practice, Indiana purchases connected vehicle data that extends 10 miles into all neighboring states. This provides an ability to monitor work zones, incidents, and re-occurring congestion in adjacent states that may impact Indiana, as well as understanding when Indiana freeway congestion impacts neighboring states. This paper presents case studies that explain how cross border queueing can be monitored and summarized over a year for the I-94, I-90, I-70, I-69, I-65, I-64, I-275 and I-265 Indiana Interstates. The inbound IL to IN segment of I-94 had the largest median hours of queuing with 69.1 hours per week. The outbound IN to KY segment of I-275 departing Indiana had the largest median hours of queuing with 19.5 hours per week.

Federal Highway Administration AB - The primary objective of this project was to compare ramp metering algorithms and develop guidelines for improving ramp metering operations in Texas. As part of this research project, researchers collected data at several sites in Houston, Texas. Data analysis showed that many congested freeways are facing heavy ramp demand and require significant changes in existing ramp metering operations if ramp metering continues to be used as part of freeway traffic management. Furthermore, researchers used computer simulation to compare the effectiveness of ALINEA with queue flush with the existing strategy of metering at the maximum rate with queue flushing. Researchers found that ALINEA does not provide any benefits when queue flushing is permitted. Under heavy demand conditions such as those in Houston, the current strategy to meter at the fastest rate remains the most beneficial. However, this strategy also provides limited benefits. Finally, researchers developed guidelines and recommendations for current and future ramp metering operations in Texas. This report documents the research results.

Federal Highway Administration AB - In an urban environment drivers typically have numerous information sources contributing to performance of driving tasks. An objective of this research is development of a practical tool to help traffic and safety professionals analyze driver information load and select countermeasures for information level corrections. The first task to accomplish the project objective was development of a methodology for quantitative description of informational dimensions of urban freeways, taking into account the complex impact of different information sources. Corresponding with a Positive Guidance concept, all sources of information were classified into three groups in relation to highway, traffic control, and traffic. The first group includes such roadway design features as horizontal and vertical alignments, number of traffic lanes, width of traffic lanes and shoulders, entrance and exit ramps. The traffic control group includes road signs, signals, and pavement markings. The third group, traffic, characterizes impacts of other vehicles on driver information load. In addition, the analysis considers that urban freeways are typically surrounded by numerous objects that are not related to traffic but can take driver attention or create inappropriate background for road signs and therefore interfere with perception of more vital information. These include commercial electronic billboards, commercial static billboards, buildings, and any other objects that consume driver attention but do not relate to traffic. With the purpose of determining typical combinations of the above-mentioned information sources, urban freeways in Texas were investigated. Based on joint analysis of the information load and principles of driver information processing, information quantification criteria were identified and the methodology for quantitative description of informational dimensions of urban freeways was developed. The structure of the utilized information load matrix isolates impacts of different information sources, and, therefore, with further investigations of their impact on driver behavior and reactions, will allow determination of each source contribution.

Federal Highway Administration AB - Permanent stormwater quality structures in developed urban areas require the use of smaller footprints and underground structures. This project was undertaken to see if an underground treatment structure composed of off-the-shelf precast concrete sections would have adequate performance and require minimum maintenance. The project consisted of a literature review of small footprint and underground stormwater treatment devices, their cost, performance, and maintenance considerations; a physical model study to test the principles to be employed and construction of a full-scale prototype for proving the concepts. The project clearly demonstrated that extended detention can be an effective tool in removing suspended solids from stormwater compared to other proprietary devices. It also shows that less frequent maintenance will be needed to maintain the overall level of performance. While the efficiency of the structure is around 75 percent removal, approximately 17 percent of the solids discharged can be attributed to resuspension. Several refinements show promise in significantly reducing the resuspension loading which could increase the overall efficiency to over 80 percent with maintenance intervals in excess of twelve months. For this reason, the project is being extended another year to further refine the performance and develop better design guidance.

The Texas Department of Transportation (TxDOT) administers and enforces these regulations except in certain cities that have been delegated to assume these responsibilities. The Department is interested, however, in the options for outsourcing some of its responsibilities to the private sector. The researchers evaluated several of these options and concluded that outdoor advertising control is an activity suitable for outsourcing. The basic option, to outsource only the taking of sign inventory, would have an annual cost to TxDOT of at least $178,000 and possibly as much as $476,000. Outsourcing the responsibility for evaluating permit applications for new signs would add between $79,000 and $149,000 to this cost. Other options that were suggested for TxDOT’s consideration include measures to increase enforcement on rural roads.

In these areas, rail grade crossings are much less likely to have warning lights or crossing gates primarily due to the lack of electricity. Such unprotected or passive crossings have the majority of the grade crossing fatalities and accidents. In order to reduce rail accidents, enhanced warning systems are needed at as many passive crossings as possible. We propose to create a new energy harvesting approach based on the motion of the wheels to generate sufficient power for an LED-based grade crossing warning system. Recent advances to create small and powerful magnets allow for the design of a non-contact power generation approach that is activated with each passing wheel. The feasibility of this approach has been shown in the first year of this project and an initial prototype will be designed and tested during the second year.

Office of the Assistant Secretary for Research and Technology AB - Efficient railroad infrastructure monitoring and assessment is a critical issue for safe and sustainable operations. Apart from scheduled inspection and routine maintenance, there is a need for rapid assessment of the rail network after major events. For example, a storm can affect the traversability of a line (downed trees, rocks or flooding can block the line). Since it is impossible to continuously monitor the whole network before and after a major event, there is always the risk of an accident for a train crossing a blocked line if the obstacle\damage ahead is realized too late. In this project, we aim to develop intelligent aerial drones capable of identifying and following railway lines, while assessing the traversability and providing an early warning whenever needed. The drone system can be carried and deployed by the locomotive, with the mission to fly ahead of the train within the railway right of way for a distance that is safe to provide this early warning (2-3 miles). The main characteristics of this system are: i) Visual based identification and autonomous following of the line; the system will be able to work even in GPS-degraded environments (tunnels, dense forests); ii) Collision avoidance capability where the drone senses and avoids obstacles; iii) Track centering capability where the drone follows the same line regardless of the number of tracks in the field of view; and iv) Identification and mapping of any obstacles identified blocking the line.

Office of the Assistant Secretary for Research and Technology AB - Safety at grade crossings is a major concern due to the number of accidents every year. Many innovative technologies have been proposed to automate the monitoring of crossings. The goal of this research is to investigate the use of Artificial Intelligence (AI) and Deep Learning (DL) to monitor grade crossings and detect various hazardous conditions such as vehicles, pedestrians, cyclists, animals, warning lights, and others. Limitations of previous work show the need to improve the size and balance of the data. The work in this proposal aims to address limitations in the current model and to make new advances by (1) increasing the number of photos in the dataset using real video streams; (2) using captures from a train simulator videogame environment; (3) addressing the issue of imbalanced dataset for training and validation; and (4) hyper-optimizing the model for accuracy and real-time performance. This research relates directly to the strategic research goal of UTCRS of reducing fatalities and injuries at highway-rail grade crossings (HRGCs); and relates to the railway operation systems research area of autonomous systems for grade crossing safety. The outcomes of this research should advance knowledge in automated monitoring of hazards at grade crossings, and result in a model that can be implemented in cameras for automated hazard monitoring at grade crossings.

Office of the Assistant Secretary for Research and Technology AB - This study investigates an electromagnetic energy harvester that utilizes an impact-driven frequency up-conversion mechanism to convert low-frequency vibrations into electrical power. The device consists of a plastic cantilever beam with a copper coil attached at its free end, oscillating between two stationary neodymium magnets. A stopper beneath the resonator induces controlled impacts, increasing stiffness and introducing nonlinear dynamics that broaden the resonance frequency range. A finite element model of a multi-span beam under moving loads was developed to assess acceleration inputs, and subsequently an analytical model of the energy harvester with impact effects is developed to analyze the induced voltage under measured acceleration signals of the multi-span beam, both with and without impact. An experimental prototype is also fabricated to validate the effect of impact on widening the harvester’s frequency response across different acceleration intensities. Results show that the impact mechanism increases induced voltage and widens operational bandwidth. Specifically, with a 7 mm impact gap, the maximum voltage improved from 32 mV (no impact) to 43 mV (with impact) at 0.20g acceleration, while the frequency bandwidth expanded by 1 Hz.

Research and Technology Implementation Office A3 - United States. Department of Transportation. Federal Highway Administration AB - In December 2001, the Design Division and Bridge Division of Texas Department of Transportation released a new standard for an approach guard fence to concrete bridge rail transition that complies with the testing requirements of National Cooperative Highway Research Program (NCHRP) Report 350 for use on high-speed roadways. Because there are no national transition designs that have been developed and tested for lower speed conditions, the same transition standard is typically applied to all roadways regardless of speed. However, the new thrie beam transition design represents a significant increase in installation cost and complexity over the previous design. Thus, it may be cost prohibitive to require use of the same design on all roadways. The purpose of this research was to develop a transition that is suitable for use on lower speed roadways and that is less expensive and complex than the current high-speed design. A low-cost transition was successfully evaluated at 45 mph impact speeds under NCHRP Report 350 Test Level 2 conditions. A second objective of the project was to evaluate the need for the curb detail that is one of the design elements of the newly adopted thrie beam transition design. Elimination of the curb would greatly enhance installation flexibility and reduce installation cost. The assessment of the curb was accomplished through full-scale crash testing.

Historically, travelers could stop to read the interpretive markers. Then, printable guidebooks were created, with some agencies still using these today. With contemporary technology, interactive online maps are becoming more commonplace, some which have a companion mobile application (app). This research reviewed twenty-three apps to identify some of the innovative content. It asked peer agencies that use apps about their experiences. Allowing offline use and ensuring that continued maintenance can be performed are key needs. The use of augmented reality is one of the most novel approaches that is still in its infancy. The research also reviewed twenty-eight online interactive maps to identify best practices. Enabling users to provide feedback via integrated forms and allowing for open and keyword-focused searches were two best practices. Many of the recommendations were related to avenues for sharing the data, including on a publicly accessible online interactive map. Several suggestions for improvements to the online interactive map were provided. There is also a need to plan for how the interpretive marker data is managed going forward.

A2 - United States. Department of Transportation. Federal Aviation Administration. Center of Excellence for Alternative Jet Fuels and Environment A2 - Washington State University A3 - United States. Department of Transportation. Federal Aviation Administration. Office of Environment and Energy AB - Sustainable aviation fuel (SAF) production is essential for decarbonizing the aviation sector in the short and midterm as well as maintaining the global competitiveness of U.S. airlines, supporting job creation, and ensuring U.S. energy independence. The near-term U.S. SAF target, set by the SAF Grand Challenge, is 11.4 billion liters (3 billion gallons) of domestic SAF production by 2030, with a minimum 50 % reduction in lifecycle greenhouse gas emissions. In 2024 U S. SAF production was less than 2 % of the stated goal, demonstrating that the remaining production growth is significant. Barriers to scale-up include technological readiness, feedstock availability, and delays in facility development. This study uses a database of U.S. SAF production announcements to assess the feasibility of attaining the 2030 targets by analyzing production potential, construction paradigms, feedstock availability, and CO2 abatement cost. Our analysis indicates that the hydroprocessed esters and fatty acids pathway will dominate U.S. SAF production through 2030, with notable contributions from alcohol to jet and coprocessing. However, probable U.S. production of SAF is predicted to fall short of the current goal by 3.6-billion liters although there are scenarios that meet the goal. Existing U.S. policies favor on-road transportation fuels and are insufficient to drive necessary SAF production scale-up. Additional measures, such as non-government scope 3 emission purchases, long-term incentives, a national low-carbon fuel standard, or volume mandates, are options to close the gap. These measures are needed to ensure the profitability of SAF production and competitiveness with renewable diesel.

Prior approaches to this problem have consisted of historical correlations, empirical drag and simplified propulsion system models (Raymer, 2018; Roskam, 2002; Torenbeek, 1982). TASOPT, originally written in FORTRAN and developed by Mark Drela (Drela, 2011; Greitzer et al., 2010), took the approach of basing the aerodynamic, propulsion, and weight estimates on low-order models built on first-principles structural, aerodynamic, thermodynamic theory to the extent possible. This approach gives confidence that optimized aircraft designs generated by the program are not spurious artifacts of inappropriately extrapolated empirical data. This package, TASOPT.jl, is a modern, Julia based implementation of the same principles, written with the goal of extensibility in mind. The current package leverages open-source Julia packages where useful to provide an easy-to-read and maintain software. TASOPT.jl also introduces additional functionality such as capability to model some forms of hydrogen fuel aircraft. In addition, the software allows users to connect it with other aircraft propulsion system tools (such as NPSS) and aircraft environmental impact assessment tools (such as Aviation Emissions Inventory Codes) (Simone et al., 2013).
