Extensive testing at two construction sites, an MSE wall project near Golden, CO, and multiple MSE wall/bridge approach projects near Wheat Ridge, CO, revealed that the light weight deflectometer (LWD), dynamic cone penetrometer (DCP), and Clegg Hammer are all capable of assessing the compacted state of Class 1 backfill. Field test data also revealed that the current CDOT practice of single position nuclear gauge (NG) testing is inadequate. An evaluation of field data demonstrated that target values (TVs) exist for the LWD modulus (ELWD), Clegg Impact Value (CIV), and DCP penetration index that could serve as surrogates for the current 95% compaction requirement. The DCP exhibited two key limitations: moisture sensitivity and penetration resistance from placed geogrid (MSE walls) and geofabric (bridge approach). Because the LWD and Clegg Hammer do not possess the same limitations, these two devices were deemed most suitable for QA of MSE wall and bridge approach earth work compaction.

University Transportation Centers (UTC) Program AB - Truck platooning, a technology where connected and automated trucks travel in closely linked convoys, promises significant reductions in fuel consumption and emissions. However, these long convoys present a major safety hazard on existing roadways, particularly on rural two-lane undivided highways. On these roads, human drivers must use the oncoming traffic lane to overtake, and a long truck platoon acts as a dangerous and extended barrier. To address this problem, we established a comprehensive framework to safely integrate platoons into mixed traffic. The research progressed through four steps. First, we modeled the precise time and distance required for a human driver to safely pass a platoon. Second, we developed a dynamic algorithm that determines safe platooning limits, such as the maximum number of trucks allowed, based on real-time road geometry and oncoming traffic. Third, we tested these rules using advanced traffic simulations. Finally, we designed an active gap opening control system, allowing automated trucks to proactively split apart and provide a safe harbor for passing vehicles. Our findings demonstrate that while long platoons operate safely on multilane highways, they require strict, dynamic limitations on two-lane roads. This research provides transportation policymakers with a clear, data-driven blueprint. By shifting from rigid rules to context-aware operational rules and utilizing cooperative gap opening technologies, agencies can preserve the economic benefits of truck platooning while rigorously protecting the safety of everyday drivers.

In this collaborative effort, the research team will collect full-scale fuselage panel test data to assess the damage-tolerance (DT) performance of certain EMST fuselage design concepts and compare the results to the DT performance of fuselage structures constructed from conventional aluminum materials that are available today. Several technologies will be considered, including advanced aluminum-lithium (Al-Li) alloys and selective reinforcement of the structure using fiber metal laminates (FMLs). Data from this study will be used to verify improved weight and structural safety performance of the EMST design concepts as compared to fuselage structures built from conventional aluminum materials. The data will also be used to assess the relevance of existing FAA policies (e.g., regulations and guidance materials) and to inform whether safety standards and guidance materials should be created or revised to provide improved safety beyond that afforded by existing airworthiness standards. Results from the third panel test are summarized and compared with panel 1 and panel 2 in this report and will be compared to future tests on panels containing reinforcement using FML to assess the damage-tolerance performance.

The purpose of this study was to determine the effectiveness of Class N pozzolan and other pozzolans for mitigating alkali-silica reaction (ASR) and resisting sulfate attack. First, a literature review was performed to find research on Class N pozzolan. Second, other state departments of transportation (DOTs) were contacted to determine if Class N pozzolan is used and how it is specified. Third, laboratory tests were conducted to determine the effectiveness of Class N pozzolan and other materials in mitigating ASR when compared to Class F fly ash. Using one source of Class F fly ash, one source of Class N pozzolan, and one source of reactive aggregate (fine and course), the effectiveness of Class N was determined by testing each combination in accordance to Colorado Procedures CP-L 4201 and CP-L 4202. Class N pozzolan was found to be effective in mitigating ASR. Once the effectiveness of Class N and other products tested was determined, further testing on Class D mix design was performed for potential effects on fresh and hardened concrete. Testing included entrained air on plastic concrete, rapid chloride permeability (ASTM C1202-05), and compressive strength at 7, 28, and 56 days.

The method strives to choose proper highway segments where the conditions of sampled assets can represent the maintenance performance of the full inventory within the network. To this end, the researchers present a high-dimensional clustering-based stratified sampling (HDCSS) method for roadway asset inspection. The method allows transportation agencies to adjust parameters, such as sample size, inspection frequency, and assets of interest. The HDCSS method integrates asset deterioration prediction, high-dimensional clustering, and locality-sensitive hashing (LSH). The sampling method can also incorporate various features of the asset network, such as asset condition, geographic information, traffic condition, and geometric design, as the information upon which samples can be selected. The method is adaptable to any asset changes, as the sampling process is constantly updated with previous inspection results and maintenance records.

Office of the Assistant Secretary for Research and Technology AB - Motor vehicle crashes are one of the leading causes of on-duty death for law enforcement (LE) officers, firefighters, and emergency medical service (EMS) personnel. This manuscript examines the potential benefits, limitations, and human factors considerations when implementing advanced driver assistance systems (ADAS) in LE fleets, with additional considerations when incorporating ADAS features in ambulances and fire trucks. We found that ADAS, specifically collision avoidance systems focused on longitudinal control and lateral control, are likely to significantly reduce crash risk in LE vehicles during normal driving scenarios. Conversely, collision avoidance systems may interfere with emergency driving and tactical driving maneuvers when active. Driver-vehicle interfaces for ADAS-equipped emergency vehicles should ideally have adaptive and flexible ADAS features that allow for their selective activation and deactivation based on situational needs. ADAS training for first responders should be multifaceted, including both general and specialized components to encourage accurate mental models.

Department of Transportation. Office of the Assistant Secretary for Research and Technology AB - A high-dimensional clustering-based sampling method for roadway asset condition inspection is proposed in this study. The method complements existing literature by selecting sample roadway segments that contain multiple types of assets (e.g., signage, shoulder work, pavement marking, etc.) for the accurate estimation of their respective levels of maintenance (LOMs). This is consistent with the standard maintenance procedure, as inspection activities are often conducted on roadway segment basis. The proposed method consists of three components: current condition estimation, similarity matrix construction, and stratification. Current condition estimation predicts assets' "current condition" by considering historical inspection records. Similarity matrix construction represents the core piece of the sampling framework, which employs a locality-sensitive hashing algorithm to define the similarity between segments. The stratification process is implemented with spectral clustering, which assigns segments into clusters based on the similarity matrix. The proposed method outperforms simple random sampling, which is widely used by state agencies, especially under the circumstances where LOM varies greatly across assets. The main highlight of the proposed method is the ability to select sample segments with multiple types of assets that are representative of their respective LOMs of the full inventory, which directly translates into an efficient maintenance activity management. The method is implemented using asset inspection records in the state of Utah from September 2014 to March 2016. It represents a potentially useful tool for agencies to effectively conduct asset inspection, and it can be easily adopted for choosing samples containing multiple features.

The statistical database was then used to identify bridge candidates for field and strength testing. Ten double-tee bridges were identified as suitable for field testing and two bridges were selected for field testing. Girder distribution factors (GDFs) and dynamic load allowance (IM) were measured during the field testing of the two bridges. To verify the available moment and shear capacity estimation methods, two 45-year old double-tee girders, one 50-ft (15.24-m) long and another 30-ft (9.14-m) long were extracted from a bridge located on Nemo Road, SD, and were strength tested at the Lohr Structures Laboratory at South Dakota State University. A four-point loading configuration was selected for the strength testing. The measured data was used to validate the capacity estimation methods.

Department of Transportation. Federal Aviation Administration. Technical Center AB - Flow induced distortions of water drop fluxes and speeds seen by the instruments were predicted by use of three dimensional flow and trajectory calculation methods. Sensitivities were determined for the instruments, in isolation and mounted under the wing of an airplane, to: water drop diameter (2 to 1000 microns), angle of attack and free stream air speed. For the optical array probe in isolation and on the airplane at 0 deg angle of attack, flux distortions of practical consequence are not found. At 4 deg airplane angle of attack, partial flow stagnation under the uptilted wing causes significant decreases in both flux and speed for cloud size droplets. For the forward scattering spectrometer probe in isolation, only marginally significant sensitivities to free stream air speed are found, and no sensitivity is found to angle of attack. Both speed and flux of cloud size droplets are predicted to be undermeasured by from 12 to 24 percent depending on airplane angle of attack. For the wing-mounted instruments, effects of flow about the instruments themselves are found to be equal in importance to effects of flow about the airplane. Preferred orientation (canting) angles of distorted water drops are found to be functions of drop size, angle of attack and air speed.

Two major functions are provided by the RMMS: (1) Monitoring and Control via the Interim Monitoring and Control Software (IMCS) and (2) Management Information via the Maintenance Management System (MMS). This study analyzed the costs/ benefits of upgrading the MPS hardware with either a fully compatible conversion or a totally non-compatible environment alternative. This study considered only the MMS software requirements. The IMCS software in place is developmental and is scheduled to be replaced in the near future. It, therefore, has not been considered in this study. The cost of each of the two alternatives, (1) fully compatible and (2) totally non-compatible, for the MMS were analyzed using the Federal Software Management Support Center's (FSMC's) Conversion Cost Model. The study was performed according to the standards outlined in the FSMC report Preparing Software Conversion Studies -Report OIT/FSCS-84/001. This report describes the development of the cost and staffing schedule requirements for both the compatible and non-compatible conversion alternatives.

Office of the Assistant Secretary for Research and Technology AB - Autonomous vehicles (AVs) are expected to transform transportation systems and reshape workforce needs across engineering and related fields. Although existing AV workforce development efforts often emphasize electrical engineering, computer science, and mechanical engineering, transportation engineering remains under represented despite its importance to infrastructure, traffic operations, safety, and mobility integration. This study addresses that gap through the development, implementation, and evaluation of an interdisciplinary certificate program, Workforce for Autonomous Vehicle Engineering (WAVE), at California State University, Sacramento. The program was designed to bridge transportation engineering and electrical engineering through a two-step curriculum model consisting of theoretical educational modules and hands-on laboratory activities. Transportation engineering modules covered traffic control devices, traffic signal timing and phasing, traffic flow theory, roadway geometric design, and supplementary topics such as human factors, level of service, and intelligent transportation systems. Electrical engineering modules addressed signals and systems, sensing technologies, sensor fusion and artificial intelligence, control systems, and communication systems. The program was delivered over seven weeks to 53 civil and electrical engineering students through a customized Canvas platform and laboratory sessions using the QCar AV platform. Program effectiveness was evaluated using a three-layer framework: pre- and post-surveys, student program evaluation, and review by a panel of industry experts. Results showed substantial improvement in both student competence and confidence, strong positive student perceptions of the curriculum and laboratory experience, and strong validation from industry experts regarding he program's interdisciplinary structure and workforce relevance. The findings demonstrate that integrating transportation engineering with electrical engineering through theory-based and experiential learning provides an effective model for preparing students for emerging careers in the AV workforce.
