      <title>Emergency Life Saving through Multi-Modal Mobility (ELSa-M3) Southern Alleghenies Planning &amp; Development Commission</title>
      <link>https://trid.trb.org/View/2780506</link>
      <description><![CDATA[The Southern Alleghenies Planning & Development Commission (SAP&DC) region has a high concentration of overburdened, underserved communities that struggle with nutrition and drug addiction: hence our focus on the real and immediate problems of Opioid overdose, cardiac arrest, and anaphylactic shock. These problems are compounded by economic constraints (limited tax base to extend emergency services and surface transport), workforce and recruiting challenges (chronically understaffed and short-staffed emergency services), and geography (a mountainous region that limits straight-line surface response). To improve lives and reduce harm through transit in the SAP&DC region, we have to find creative ways to respond to medical emergencies both faster and cheaper. The Emergency Life Saving through Multi-Modal Mobility (ELSa-M3) project is an innovative use of uncrewed aircraft systems (UAS, or drones) to enhance emergency services logistics in the region through a public ground-based sensor network integrated with airspace management. ELSa-M3 will utilize UAS to improve emergency response time and resiliency by responding to emergency calls with drones delivering NARCAN (Opioid overdose), EpiPen (allergic shock), Tourniquet (bleeding), and AEDs (cardiac arrest). The prototype system developed during the first stage of our SMART grant addresses real world issues in this region and can improve access to healthcare services and the quality of life for the underserved communities within the project area and the broader Stage 2 area. Stage 1 of the ELSa-M3 project was located in a historically income, health, housing, pollution and transportation disadvantaged community straddling the border of Cambria and Somerset Counties, centered on Johnstown, Pennsylvania, and nearby communities.]]></description>

      <title>CI/CD for Mission-Critical Systems: A Framework for Any Level of Rigor</title>
      <link>https://trid.trb.org/View/2784490</link>
      <description><![CDATA[Modern mission-critical ground vehicle systems must adapt to rapidly evolving threats, deploying changes in months or days while maintaining reliable and safe operation. Historic manual development and testing methods cannot keep pace without compromising safety assurances. Continuous Integration and Continuous Deployment (CI/CD) pipelines offer proven approaches to accelerating development, but implementing them for mission-critical systems requires careful attention to verification rigor.This paper presents a practical framework for implementing CI/CD pipelines across any level of rigor, from rapid prototyping to DO-178C and ISO 26262 certified systems. Drawing on experience from aviation, medical device, and ground vehicle development, the framework provides guidance for each pipeline stage based on the system’s desired level of rigor. This framework includes an examination of the value of Software-in-the-Loop vs Hardware-in-the-Loop testing to optimize development timelines while maintaining software quality.]]></description>

      <title>Prototyping a Low-cost Roadside Device System for Cooperative Automated Driving: Integrated CRM/UWB Localization, Work Zone Geometry Reconstruction, and WZDx-Ready Navigation Refinement: Data Management Plan</title>
      <link>https://trid.trb.org/View/2772824</link>
      <description><![CDATA[This project, titled "Prototyping a Low-cost Roadside Device System for Cooperative Automated Driving", will evaluate the performance of a low-cost roadside device system, the Connected Reference Marker (CRM) System. The CRM system can facilitate Connected and Automated Vehicle (CAV) localization by providing real-time distance measurement and road geometry changes (work zone, i.e.). Therefore, the CRM system has the potential to serve as a gateway system for infrastructure-based cooperative driving automation (CDA) due to its low cost and easy deployment. Specifically, this project will build a prototype system and evaluate the localization accuracy in various scenarios; in addition, the prototype system will be used to detect the boundaries of work zones, as improving access to work zone data is one of the top needs identified through the USDOT Data for Automated Vehicle Integration (DAVI) effort. The detected boundaries of work zones will be later translated into a data feed following the Work Zone Data Exchange (WZDx) specification, a national work zone data standard pioneered by USDOT to meet the DAVI requirement and a critical part of the Roadway Digital Infrastructure (RDI) strategy. The data collected during this project is from the in-lab and field experiments and is used to measure the CRM system's performance. This data management plan describes the data that will be collected and how it will be stored, accessed, and archived.]]></description>

      <link>https://trid.trb.org/View/2772679</link>
      <description><![CDATA[Although significant progress has been made in automated driving technologies, technical challenges still exist, especially for complex Operational Design Domains (ODDs). A low-cost roadside device system, the Connected Reference Marker (CRM) System, has been developed to support Connected and Automated Vehicles (CAVs) in those ODDs. The CRM system can facilitate CAV localization by providing real-time distance measurement and road geometry changes (i.e., work zones). Therefore, the CRM system has the potential to serve as a gateway system for infrastructure-based cooperative driving automation (CDA) due to its low cost and easy deployment. This project will evaluate the performance regarding localization and road geometry data provision in field experiments.

      <title>Research on Reliability and Durability Testing and Evaluation Technology for Hub Motor Corner Modules</title>
      <link>https://trid.trb.org/View/2778026</link>
      <description><![CDATA[With the development of high-performance hub motors and modular assembly integration technologies, their reliability and durability have become key factors restricting industrial applications. Existing standards are mostly aimed at the hub motor itself, lacking systematic testing methods for highly integrated corner module systems. Based on a National Key Research and Development Program project, this paper conducts a series of research on reliability and durability test and evaluation technologies for the hub motor corner module system. By means of collecting vehicle-load spectra and combining user- relevance techniques, a multidimensional assessment framework is established, encompassing bench-scale axle-coupled tests, full- vehicle road reliability tests, and component-level environmental tests. The research outcomes have been applied to the testing and validation of actual prototype vehicles and components. Test results indicate that the developed testing methodology can effectively identify potential failure, providing crucial technical support for the optimized design and industrialization of hub motor corner modules.]]></description>

      <title>Prototyping Automated Framework for Asset Extraction and Characterization from Mobile Lidar Data</title>
      <link>https://trid.trb.org/View/2752293</link>
      <description><![CDATA[To be able to handle the statewide mobile lidar data ODOT collects efficiently, there is a need for a robust workflow with significant automation that can extract many types of features by effectively leveraging various feature extraction tools and algorithms to support applications. In particular, road characterization has been identified as a key application for information extraction from mobile lidar data. In this literature review, the team first provides a brief overview of the model inventory of roadway elements (MIRE 2.0) to help identify the attributes that are of interest as well as feasible to extract from mobile lidar data. Next, a review of the existing commercial software summarizes the common challenges in using these solutions for feature extraction and characterization tasks. Lastly, the existing work related to road characterization is reviewed covering the topics of ground filtering and road extraction, cross slopes and grades, and horizontal curve, followed by a summary of the benefits of using mobile lidar data as well as the challenges of the existing studies.]]></description>

      <title>Research on Parameter Matching of Electric Vehicle Powertrain System</title>
      <link>https://trid.trb.org/View/2761697</link>
      <description><![CDATA[This paper focuses on the parameter matching of key components and the                     improvement of overall vehicle performance for a certain front-wheel drive pure                     electric vehicle. Firstly, based on the target performance of the vehicle, the                     rated/peak power, speed, and torque of the permanent magnet synchronous drive                     motor, as well as the capacity, voltage, and series-parallel scheme of the                         LiFePO4 power battery, are systematically calculated. Meanwhile,                     the gear ratio of the transmission system is determined based on the dual                     constraints of the maximum speed and the maximum gradeability. Subsequently, the                     vehicle model is built using AVL Cruise, and the maximum speed, 0-100 Km/h                     acceleration time, maximum gradeability, and NEDC range are simulated and                     verified under steady-state and transient conditions. The results show that the                     maximum speed of the prototype vehicle reaches 139 Km/h, the 0-100 Km/h                     acceleration is 7.98 s, the maximum gradeability is 33.2%, the power consumption                     per 100 Km is 12.12 KWh, and the range is 485 Km, all of which are superior to                     the design indicators. The research verifies the rationality of the proposed                     parameter matching scheme and can provide a theoretical basis and engineering                     reference for the forward development of the power system of pure electric                     vehicles of the same level.]]></description>

      <title>Aerial–aquatic unmanned amphibious vehicles: A review of prototypes, modeling, and control</title>
      <link>https://trid.trb.org/View/2725477</link>
      <description><![CDATA[Aerial–aquatic unmanned amphibious vehicles (AquaUAVs) have emerged as a promising class of cross-domain systems capable of operating in both aerial and underwater environments. However, the significant differences in fluid density and dynamics between air and water introduce strong nonlinearities, multimodal coupling, and discontinuous behaviors during cross-domain transitions, posing fundamental challenges to system design, modeling, and control. This paper presents a comprehensive and critical review of recent advances in AquaUAVs. Existing platforms are systematically categorized into biomimetic, fixed-wing and rotary-wing hybrid configurations, and their design trade-offs are analyzed in terms of transition capability, propulsion efficiency, and endurance. The distinctive dynamic characteristics across air–water environments are further examined, with emphasis on cross-medium modeling approaches addressing added mass effects and transition-induced uncertainties. In terms of control, representative strategies, including robust, adaptive, and learning-based methods, are reviewed and comparatively discussed under cross-domain conditions. Finally, key challenges are identified, including the lack of unified modeling frameworks, limited energy efficiency, and insufficient autonomy in complex environments. Future research directions are outlined toward data-driven modeling, intelligent control, and cooperative multi-vehicle systems.]]></description>
