The research evaluated the dead- and live-load behavior of SDCL steel bridges through a literature review, field testing of Bridge A9513, finite element modeling, degree-of-continuity (DOC) evaluations, and development of MoDOT Engineering Policy Guide provisions. The test bridge developed measurable continuity during deck placement, with construction-stage DOC values ranging from approximately 23% to 42%, indicating that it did not behave as a purely simple-span system during deck casting. After completion, the bridge developed a live-load DOC of approximately 92%. Parametric analyses showed that the proposed deck reinforcement and compression block details remained well below yield limits under factored superimposed dead and HL-93 live loading while providing substantial live-load continuity across multiple bridge geometries. Recommendations include using staged analysis, treating the intermediate bent as the critical force transfer region, considering pinned diaphragms and bond breaker plates to reduce dead-load continuity during deck placement, and refining MoDOT's SDCL guidance as additional field data become available.

Federal Highway Administration AB - Traffic Incident Management (TIM) depends on coordinated actions among transportation agencies, law enforcement, fire and rescue, emergency medical services, towing and recovery, dispatch, and other partners. This pilot project developed and demonstrated a modular immersive TIM training platform intended to supplement classroom, tabletop, online, and field-based training. The platform was implemented on Meta Quest 3 standalone virtual reality headsets and organized around reusable Virtual Operational Environments (VOEs) that separated persistent roadway settings from scenario-specific incident content. Two VOEs were developed: an Interstate VOE representing multilane, high-speed operations and a Rural Highway VOE representing a two-lane, two-way roadway with opposing traffic and constrained response space. The platform incorporated first-person navigation, selected object interactions, in-application voice communication, rule-based simulated roadway traffic, shared sessions supporting up to four participants, and an initial Unity-Open AI application programming interface connection that presented model-generated text within the VR application. Three pilot demonstrations were conducted with Missouri Department of Transportation personnel and TIM partners. Demonstration feedback led to further refinement of the Rural Highway VOE and implementation of an injured-driver avatar and related animation. Additional updates involving towing and recovery, participant orientation, scenario content, structured data capture, after-action review, and AI-enabled virtual responders were also implemented. The demonstrations supported the technical feasibility and operational relevance of the platform but did not constitute a formal evaluation of training effectiveness. A focused second phase is recommended to expand scenarios, develop validated role-specific virtual responders, implement controlled scenario actions and instructor oversight, and conduct technical, usability, operational-validity, and training-effectiveness evaluations.

Center for Urban Transportation Research A3 - Florida. Department of Transportation AB - Nighttime driving presents a disproportionate safety challenge on arterial roadways, particularly in Florida, where more than half of all traffic fatalities occur after dark despite lower traffic volumes. Nighttime conditions introduce multiple risk factors, including reduced visibility, increased speeding, impaired driving, and diminished driver expectancy, all of which contribute to greater crash severity. This study investigates how innovative traffic signal timing design and operational strategies can improve nighttime safety while maintaining efficient traffic flow along arterial corridors. The research employed a comprehensive, multi-method approach that integrates a literature review, stakeholder interviews, national case studies, and before-and-after field evaluations on selected Florida corridors. The analysis focused on signal timing strategies, including shorter cycle lengths, signal progression for speed management, early free operation, and rest-in-red control. It also evaluated pedestrian treatments such as rectangular rapid flashing beacons, pedestrian signals, and leading pedestrian intervals, together with emerging technologies including adaptive signal control, artificial intelligence-based analytics, enhanced detection systems, and connected vehicle applications. These strategies were assessed for their effectiveness in improving nighttime arterial safety. The findings demonstrate that nighttime-specific signal timing strategies reduce risky driving behaviors, improve traffic operations, and enhance pedestrian safety. Case studies and field evaluations reveal measurable reductions in unsafe driving behavior when optimized signal timing is combined with targeted pedestrian treatments. Overall, the research concludes that integrating nighttime signal timing strategies with coordinated operations using shorter cycle lengths, targeted infrastructure enhancements, and emerging technologies are essential for achieving sustainable improvements in nighttime arterial safety.

The European testing equipment was used to improve the quality of the hot mix asphalt (HMA) pavement. The primary reason the Colorado DOT and the FHWA Turner Fairbank Highway Research Center obtained the equipment was to improve the quality of HMA pavements. The purpose of this report is to document a case history of the use of the European equipment to improve an HMA pavement on a project in Colorado. Cost effective adjustments were identified to produce a high quality pavement that resists rutting and stripping. The three changes were: 1) increasing the optimum asphalt content, 2) adding a liquid anti-stripping additive with hydrated lime, and 3) changing the crude oil source and refinery. The cost of the HMA increased from $24.00 to $25.00, 4.2%, for a project cost increase of $80,000. These changes likely saved $5,000,000.

This program was then modified and validated for analyzing the performance of Geosynthetic-Reinforced Soil (GRS). The validation was conducted by comparing the analytical results with a laboratory "element test" of soil, reinforcement, and facing; with another validated FEM program (SSCOMP); and with measurements from two full-scale test walls. Using the analytical model, a parametric study was conducted to investigate the effects of various factors on the performance of GRS walls: wall height, wall shape, backfill type, facing rigidity, reinforcement tensile stiffness/strength, and K of the backfill. The parametric study gave valuable insight into the performance of GRS walls. Some highlights of the findings are: (1) When kept near optimum moisture, cohesive backfill walls can perform at least as well as those with granular backfill provided that wetting of backfill is prevented; (2) Foundation soil has a significant influence on the wall performance; and (3) Wall facing affects lateral movement of GRS walls even under a service load of 5 psi.

Panels are intended for use as full height facing for a variety of mechanical reinforcements for fills including geotextiles, geogrids, and bar mats. Panels provide a forming surface and permanent facing for MSE walls, but are independent of the MSE mass. Panels are attached to stable MSE constructions with flexible anchors that limit earth pressures on panels. Loads on panels are minimal, and panel size and appearance may be tailored to the requirements of individual projects and sites. This offers options in construction operations and in appearance of the finished wall not previously available for MSE constructions. This report presents the basis for design of independent facing systems, presents methods for stress analysis of independent facing panels, reviews options for full-height and for stacked panel facing systems, outlines construction procedures for MSE walls with independent facing, and presents options for anchors and panels for independent facings.

Federal Highway Administration AB - A recent change from the California kneading compactor to the Texas gyratory compactor has resulted in significantly lower optimum asphalt contents. Additionally, only one laboratory compactive effort has been used in Colorado regardless of traffic or high temperature environment. Adjustments are being made to the Colorado's hot mix asphalt design procedure to address these concerns. It was decided to use results from the recently acquired European equipment to assist with the adjustments. Additionally, results were used from three other sources: 1) the previously used California kneading compactor, 2) samples from older pavements that were recompacted in the Texas gyratory, and 3) experimental field projects that used the recommended end-point stresses. Optimum asphalt contents need to be determined using varying laboratory compactive efforts that correspond to the various traffic and environmental conditions in Colorado. The recommendations presented in this report include the variable end-point stresses for the Texas gyratory to obtain the optimum asphalt content along with the traffic and environmental categories to assist designers on the appropriate selection of the specified end-point stress. Additionally, minimum Hveem stability values, minimum voids in the mineral aggregate, and an acceptable range for voids filled with asphalt are included.

Office of Aviation Research AB - This work has been conducted as part of the Federal Aviation Administration's (FAA) efforts to develop fire-resistant materials for commercial aircraft cabins. Polymers based on 2,2-bis-(4-hydroxyphenyl)-1,1-dichloroethylene (bisphenol C, BPC) have thermal and physical properties of bisphenol-A polymers but have an order of magnitude lower heat release in flaming combustion. This is due to a thermal degradation mechanism that yields only char and noncombustible gases in a fire. Two thermoplastics and one thermoset BPC-based polymer were studied to establish the decomposition mechanism of these materials. Thermal gravimetric analysis, differential scanning calorimetry, infrared spectroscopy, chromatography, and mass spectrometry were used separately and in combination to characterize the thermal degradation mechanism. Results showed that the major volatiles are hydrogen chloride (HCl) and the degradation products of the linking group. The rearrangement through stilbenes and acetylenes is responsible for the high char yield when burned.
