Office of Aviation Research AB - During February 1999, the Naval Air Warfare Center Weapons Division (NAWCWD), China Lake, conducted a series of simulated uncontained engine failure structural impact tests. A large gas gun was used to launch turbine engine fan blade segments into an aircraft fuselage. The impacts were documented and analyzed with high-speed photography. Impact velocities, presented areas, and residual velocities were calculated. The data were then compared to analytic results predicted by the Joint Technical Coordinating Group for Munitions Effectiveness (JTCG/ME) penetration equations. These equations were originally develop to predict the penetration and residual velocity of ballistic weapon projectiles upon impact with various vehicles. The ballistic prediction equations developed for warhead fragments are the closest in geometric shape to turbine engine blade fragments. The data comparison shows good agreement for the predicted and experimental residual velocities.

Export RIS Citation Information. TY - Tech Report AU - Paris, Bethany AU - Li, Ying AU - Waddle, Steven AU - Gibson, Bryan A2 - University of Kentucky. Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - The Kentucky Transportation Cabinet (KYTC) lets around 700 contracts year valued at over $1 billion. One of KYTC's foremost goals is to deliver projects on time and on budget. However, over the past five years achieving these twin goals has grown in difficulty due to material shortages, widespread inflation, supply chain disruptions, and the tight labor market triggered by the COVID-19 pandemic. Although material shortages have abated and supply chain disruptions have eased, instability is seemingly a permanent feature of the national and global economies. As such, Cabinet decision makers need reliable tools that can be used to understand historical trends in material pricing and forecast future short-term variability in commodities markets. Equipped with this information, KYTC can proactively devise and implement strategies to mitigate future impacts of price increases and supply chain disruptions. To arm the Cabinet with the data it needs to make judicious investment and program management decisions, Kentucky Transportation Center (KTC) researchers have developed two Tableau-based dashboards - a Unit Bid Dashboard and a National Commodity Trends Dashboard. These dashboards house historical pricing data for essential highway construction inputs both at the state and national levels and give users the ability to develop one-year price forecasts. To ensure these dashboards play a role in future decision making, they should be updated regularly.

Export RIS Citation Information. TY - Tech Report AU - Blandford, Ben AU - Lammers-Staats, Erin AU - Gregory, Emma A2 - University of Kentucky. Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - Transportation agencies are increasingly more challenged by the effects of extreme weather and national hazards on transportation assets. Severe weather events in Kentucky have become more frequent and more costly. These extreme events damage transportation assets, increase maintenance costs and strain transportation budgets. Climate models predict changing conditions to occur over the next century that differ from historical data. In Kentucky, models predict a warmer and wetter environment. The goal of this research is to help KYTC plan for extreme weather and natural hazards events, as well as absorb, recover from, and adapt to the resulting damage. Researchers determined where Kentucky transportation assets experienced damage from climate events and explored the consequences of not taking action to improve the resilience of Kentucky's infrastructure. They utilized KYTC operations management system data to create GIS maps of roadway damages incurred from weather events. Climate data from Oak Ridge National Laboratory was sourced and combined with the records of damages. Then, researchers modeled the relationship between weather events and impacts to the transportation system. The result of the study is a four-step framework for a cost-benefit analysis the practitioners can use to determine the amount of damage that a weather event could cause. The framework can be used to calculate direct costs of project design, materials, and labor, as well as indirect costs and benefits to the community. Practitioners can target improvements to create a more resilient transportation system. Harlan County was used as a case study and showed that narrow roads, mountainous terrain, and lack of route redundancy created transportation system vulnerability.

This study, commissioned by the Kentucky Transportation Cabinet (KYTC), examined how states characterize, detect, and respond to chameleon carrier activity and assessed its financial and safety impacts in Kentucky from 2020 through 2025. The research team conducted a literature review of existing agency practices and relevant stakeholder perspectives, reviewed administrative codes and statutes across 13 pilot states, and administered two structured surveys to state motor carrier credentialing officials examining carrier characterization and enforcement practices. An analysis of KYTC's carrier data flagged by CVIEW provided estimated Road Fund revenue losses attributable to suspected chameleon carriers across four tax and fee programs. Safety analyses compared flagged and non-flagged carriers across roadside inspection violations, citations, and crash involvement using FMCSA data. Research results revealed significant definitional and enforcement gaps across states and documented financial and safety impacts attributable to suspected chameleon carrier activity in Kentucky.

Export RIS Citation Information. TY - Tech Report AU - Brown, Mallory AU - Martin, Andrew AU - Koo, Jeeyen AU - Walton, Jennifer A2 - University of Kentucky. Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - The Kentucky Transportation Cabinet's (KYTC) Department of Vehicle Regulation (DVR) administers numerous fees and taxes. Many administered by the two divisions in DVR - Motor Vehicle Licensing (DMVL) and Motor Carriers (DMC) - have remained unchanged for many years despite salary increases, the adoption of more com-plex and expensive technologies, and inflation raising administrative costs. This report provides in-depth assessments of 10 fees and taxes (selected by division administrators). Six are administered by DMVL - certificate of title, duplicate title, vehicle title history report, additional registration fee, reflectorized license plate fund, and trailer registrations - and four are managed by DMC, including International Fuel Tax Agreement (IFTA) registration/decals, Kentucky Intrastate Tax (KIT) registration/decals, the Kentucky Highway Usage Tax (KYU), and Kentucky Intrastate for Hire. Based on state budget data, reports from the Kentucky Automated Vehicle Information System (KAVIS), and data from other states in the Southeast, researchers recommend modifying each of the 10 fees analyzed. The report provides detailed justifications for doing so. A nationwide survey of transportation agencies found that changes in fees and taxes are typically enacted through the legislative process, but that relevant subject-matter experts rarely have the opportunity to provide input when legislation is drafted. Most states do not track how much it costs to administer fees and taxes, weakening their ability to determine if fees are sufficient to finance the provision of services. However, many have compared their fees and taxes to those charged by other states. Kentucky's DVR will benefit by reviewing and updating fees and taxes regularly and developing an inventory of all fees and taxes it administers so it has better knowledge of what resources are necessary to coordinate administration. KYTC should also elicit the participation of DVR administrators when changes in fees or taxes are contemplated by legislators.

Export RIS Citation Information. TY - Tech Report AU - Marks, P. Gayle AU - Gibson, Bryan A2 - University of Kentucky. Kentucky Transportation Center A2 - Kentucky Council on Post Secondary Education A3 - Kentucky Transportation Cabinet AB - Each day, Federal Aviation Administration (FAA) air traffic control specialists (ATCSs) handle over 44,000 flights and oversee 29 million square miles of the United States National Airspace System. However, staffing shortages have grown more acute over the past 10 years, which has led to delayed and cancelled flights, a higher number of close misses over a short period of time, and frustrating air travel experiences. While the FAA has redoubled its efforts to recruit more ATCSs, it has limited training capacity. To expand training options available to prospective ATCSs, the FAA is working with postsecondary educational institutions to expand its Air Traffic-Collegiate Training Initiative (AT-CTI). Graduates of Standard and Enhanced AT-CTI programs can accelerate their training. Currently, no postsecondary institution in Kentucky has a Standard or Enhanced AT-CTI program. Pursuant to Senate Bill 87 (AN ACT relating to aviation), which was signed into law in 2025, this report evaluates postsecondary institutions across the state to identify good candidates to establish an Enhanced AT-CTI program. Based on discussions with industry stakeholders, reviews of FAA materials, and assessments of course offerings and degree programs, researchers concluded that Eastern Kentucky University (EKU) is the only public postsecondary institution in the state with the capacity to establish and maintain an FAA-approved air traffic control program. In early 2025, EKU's School of Aviation submitted an initial application to the FAA to establish an Enhanced AT-CTI program.

Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - Transportation practitioners use crash modification factors/functions (CMFs) to calculate the number of crashes expected once a countermeasure has been implemented. When evaluating design alternatives, CMFs can be used in conjunction with safety performance functions (SPFs) to derive crash predictions. The Federal Highway Administration (FHWA) maintains the CMF Clearinghouse as a repository for CMFs. Contributions are submitted by researchers across the U.S., Canada, and throughout the world. Typically, individual countermeasures are associated with multiple CMFs. Some CMFs only apply to a specific facility or crash types. CMF quality varies, and some only apply to a specific facility and/or crash types, regions, or times. One drawback of the CMF Clearinghouse is that practitioners must devote considerable time and have significant expertise to identify an appropriate CMF. To streamline the process of selecting CMFs, Kentucky Transportation Center (KTC) researchers updated a web-based CMF tool they originally developed in 2020. Kentucky Transportation Cabinet staff and design consultants can use the refreshed tool to select CMFs most appropriate for the state's highways and conditions. The updated tool contains significant enhancements. In addition to having a more intuitive user interface layout and better aesthetics, the new tool incorporates more than 6,000 additional CMFs that have been added to the CMF Clearinghouse. Researchers also optimized the tool for viewing on mobile devices.

Rep., Series C: Mechanical and Aeronautical Engineering and Shipbuilding, 1 (1973), pp. 1-10. A significant number of changes was made in the program for more convenient use; however, the fundamental equations remain unchanged. The results were checked in detail to insure agreement with the original solution. The program gives an appropriate solution for the resultant tangential creep forces and spin moment acting between two bodies of equal linearly elastic material properties. The creep forces and spin moment are due to lateral, longitudinal, and spin creepages. Assumptions corresponding to the Hertz contact theory are implied and two additional simplifying assumptions are made, resulting in a significant reduction in computation time as contrasted with previous solutions. Two separate computer codes were developed, the first being the general solution with extended input and output, and the second a shortened version primarily intended for use as a subroutine. Surprisingly good agreement is found to exist between the 'Simplified Theory' and published experimental results for a wide range of contact ellipse eccentricity.

Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - This report examines trends in how Kentucky District Courts have adjudicated charges related to commercial driver's license (CDL) and commercial motor vehicles (CMVs). Using court data, researchers evaluated historical patterns in charge filing volumes as well as conviction, dismissal, amendment, and diversion rates. Between 2002 and 2024, conviction rates declined and dismissals increased. Convictions peaked in the mid-70% range in the early 2000s, but fell to the mid-50% range by 2024. Speeding and other serious traffic violations - many of which are advanceable offenses - were dismissed or amended at rates that could have substantively affected the integrity of CDL holder driving records. Building on this evaluation, researchers completed an in-depth case study of the Hardin County District Court's adjudication practices and surveyed local law enforcement agencies about inspection and citation practices, knowledge of state and federal regulations, and the availability and effective-ness of equipment and training. Based on the findings of these analyses, researchers propose several recommendations to strengthen the adjudication process. These include holding annual trainings for local law enforcement focused on state and federal requirements for CDL holders, development of guidance for judges and county attorneys that describes different types of CDL- and CMV-related violations and their impacts on safety, updating the state's uniform citation form so it more clearly indicates whether an offender holds a CDL, and expanding representation on the state's CDL Advisory Committee to include local law enforcement officers as well as judges and county attorneys from rural areas.

Export RIS Citation Information. TY - Tech Report AU - Brown, Mallory AU - Martin, Andrew AU - Keathley-Helil, Valerie AU - Walton, Jennifer A2 - University of Kentucky. Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - Staff shortages and reduced budgets have made transportation agencies increasingly reliant on intelligent transportation systems (ITS) for commercial motor (CMV) vehicle enforcement activities. Technologies such as license plate readers, US Department of Transportation (USDOT) number readers, weigh-in-motion scales, static scales, and preclearance systems like PrePass and Drivewyze help automate enforcement and free up personnel to focus on inspecting those vehicles most likely to pose compliance and/or safety risks. To document adoption rates of different technologies, researchers surveyed transportation agencies, vendors, and law enforcement agencies. Surveys responses provided useful insights into how jurisdictions are approaching the use of advanced technologies to improve enforcement. Although license plate readers and USDOT readers are gaining popularity, their use remains less common than different types of scales and preclearance systems. Price could be a stumbling block to wider adoption as readers can exceed $500,000 per installation. Most jurisdictions routinely evaluate the accuracy of data generated by advanced technologies. However, many outsource assessments to vendors. Survey respondents commented that, overall, their jurisdictions are satisfied with the performance and accuracy of the technologies they have acquired to improve CMV enforcement. The Kentucky Transportation Cabinet (KYTC) and other agencies can use the findings of this report to inform future investment decisions, build more robust partnerships with private sector stakeholders and across jurisdictional lines, facilitate data exchange, and coordinate enforcement activities.

Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - Motivated by an uptick in pedestrian and bicycle traffic, as well as the inclusion of pedestrian and bicyclist weights in the Strategic Highway Investment Formula For Tomorrow, the Kentucky Transportation Cabinet (KYTC) has made significant investments in transportation facilities for nonmotorized users. Despite an intensified focus on the needs of nonmotorized users, KYTC has not yet established a formal program to track the number of people walking, biking, skateboarding, and using micromobility devices statewide. Based on a review of methods and technologies for counting nonmotorized users; analysis of counting programs established by local, state, and regional transportation agencies; and a short pilot project that compared the accuracy of manual counts to automated counts, this report advances recommendations the Cabinet may use to build a program for counting nonmotorized users. The four-day pilot project conducted in Lexington, Kentucky, found that automated counts and manual counts generated similar results - within 0.5 percent of one another over the entire study period. As KYTC prepares to roll out a counting program, it should inventory programs introduced by local governments across the state to avoid redundancies in data collection, clearly articulate the objectives of nonmotorized users counts and the purposes for which they will be used, procure durable and highly accurate equipment, identify the best locations for permanent and short-duration count stations, and pursue continuous improvement by routinely evaluating data collection to verify it is meeting program objectives. Introducing and sustaining a robust program to count nonmotorized users will help the Cabinet better understand where demand for non motorized user facilities is greatest and target future investments accordingly.

Export RIS Citation Information. TY - Tech Report AU - Howell, Brian AU - Walton, Jennifer A2 - International Registration Plan, Inc. A2 - University of Kentucky. Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - This study evaluates the feasibility for developing and maintaining a comprehensive tractor truck trailer database. The commercial motor vehicle (CMV) community currently lacks a cross-jurisdictional, centralized repository for commercial trailers registered in United States and Canadian jurisdictions. Existing federal databases provide information on interstate commercial motor carriers, vehicles, and drivers but exclude trailers. Similarly, IRP and IFTA do not collect trailer-level data, and trailer data is displayed inconsistently across its customer base. Approximately one fifth of violations in Kentucky during inspections from 2020 to 2022 were attributed to trailers, including worn tires, inadequate brakes or improper registration. The rise of organized theft affecting rail and trucking operations requires countermeasures such as incorporating better data on trailers and improving federal coordination. Law enforcement, auditors, and safety administrators experience fragmented processes and data limitations. This study examined the operational, safety, and administrative implications of such a database while also assessing technical feasibility, stakeholder perspectives, and policy considerations. Researchers circulated two surveys to law enforcement officials and jurisdictional registration agencies. Law enforcement emphasized the importance of license plate numbers, VINS, make and year, jurisdiction and expiration data. Jurisdiction agencies indicated they obtain trailer data through registrant submissions or through third party agents such as county offices. The surveys illustrated the need for a centralized commercial trailer database, standardized across different existing IT systems. The findings support a centralized CMV trailer repository to potentially yield measurable safety and credentialing benefits, allow for more consistent fee collection and improve identification of unsafe or stolen trailers.

Office of Aviation Research A4 - Wilson, Joseph AB - Premium grade titanium alloys are used for fan and compressor rotors and disks in aircraft turbine engines. Occasional upsets during processing can result in the formation of metallurgical anomalies referred to as hard alpha (HA). Although rare, low-cycle fatigue cracks initiated by HA have led to uncontained engine failures that resulted in fatal accidents such as the incident at Sioux City, Iowa, in 1989. In a report issued by the Federal Aviation Administration (FAA) after the accident at Sioux City, it was recommended that a damage tolerance approach be implemented to explicitly address HA anomalies, with the objective of enhancing conventional rotor life management methodology. The probabilistic, damage tolerance code developed in this program for low-cycle fatigue of titanium rotors/disks is intended to supplement, not replace, the current safe-life design. The code is called Design Assessment of Reliability With INspection (DARWIN) and was developed in collaboration with AlliedSignal Engines, General Electric Aircraft Engines, Pratt & Whitney, and Rolls-Royce Allison. DARWIN integrates finite element stress analysis, fracture mechanics analysis, nondestructive inspection simulation, and probabilistic analysis to assess the risk of rotor fracture. Supplementary tasks performed in this program in support of code implementation included the generation of fatigue crack growth data for Ti-64, Ti-6242, and Ti-17β in high vacuum; determination of the crack initiation behavior of artificial and natural HA defects embedded in plates of Ti-64; and development of a forging microcode to predict the movement, shape and orientation of HA anomalies during processing from ingot to billet, and from billet to a disk forging.

Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - State departments of transportation use bridge deck overlay systems to prolong bridge deck service lives. Consisting of a thin layer of material applied to a concrete bridge deck surface, overlays form a protective barrier that improves ride quality, protects embedded reinforcement from harsh environmental conditions, enhances structure durability, and improves deck drainage. Over the past 20 years, the Kentucky Transportation Cabinet has made significant investments in overlays, rehabilitating nearly 5,000 bridge decks with them - roughly 1/3 of all bridges statewide. Given the significant investment in overlays, and the fact they degrade over time - eventually re-exposing bridge decks to harsh environmental conditions, - it is critical to understand what fac-tors influence their performance and condition. This study sought to identify predictors or metrics that can ac-count for variability in overlay performance throughout Kentucky and support accurate forecasting of future conditions. Using data from the Cabinet's Bridge Management System, along with field inspections, chloride analysis, and imagery captured with a forward looking infrared (FLIR) camera, researchers attempted to identify statistical relationships between variables such as crack width/depth, crack length, average daily traffic, and amount of deck patching, and overlay condition. Limited by the constraints of a small data set (93 bridges), researchers did not uncover robust statistical relationships. Analysis found, however, that epoxy overlays exhibited the least linear cracking as well as the narrowest cracks. Asphalt overlays had the least amount of deck patching, but generally suffered from the deepest cracking. Epoxy overlays were in the best condition overall. The FLIR camera has utility for taking photos of bridge decks, however, image capture must occur under very precise conditions (e.g., no traffic, favorable weather) and image interpretation must be done by trained experts.

Federal Highway Administration AB - Geotechnical asset management (GAM), transportation asset management (TAM), and performance management have progressively become routine terms at many transportation agencies throughout the United States, Canada, and world. Geotechnical assets represent the "foundational" platform for other transportation infrastructure assets. With their extensive presence and critical role in the highway network, evaluating the condition and deterioration mechanics of these assets through a proactive assessment and intervention program helps improve the overall network condition and avoid costly, disruptive, and risky serviceability and ultimate "failures." This study presents a flexible and holistic GAM framework and workflow. To date, many GAM frameworks proposed in practice have focused on creating an asset inventory and inspection procedures. Although data collection and inspection procedures are the core of GAM, a functional and robust GAM program should address other components such as risk management as well as deterioration and performance modeling to be effectively integrated with other TAM programs and achieve agency objectives. This report provides a comprehensive discussion on asset inspection and condition evaluation procedures for four geotechnical asset families: soil slopes and embankments, rock slopes, retaining walls, and mechanically stabilized earth walls. Moreover, the research team developed applications and tools to facilitate asset inspection and condition evaluation, risk management at the asset and asset family levels, and performance deterioration modeling to allow for proactive implementation of the framework. The report summarizes the main findings, gaps, and recommendations from the study.
