      <title>Effects of Sand Equivalent and Fractured Face Percentage on Concrete Strength</title>
      <link>https://trid.trb.org/View/2780488</link>
      <description><![CDATA[This project will evaluate the effects of sand equivalent values and fractured face percentages on the performance of concrete used in transportation infrastructure. The study will use laboratory testing to examine how aggregate quality affects concrete strength and overall performance. The project will also compare sand equivalent and methylene blue testing methods and assess whether current aggregate specifications could be modified to reduce costs while maintaining concrete quality. The results will be used to develop recommendations for potential updates to the Idaho Transportation Department's (ITD's) aggregate material specifications.

      <title>Granular Carbon-Enhanced High Early Strength Concrete for Bridge Decks</title>
      <link>https://trid.trb.org/View/2780485</link>
      <description><![CDATA[This project, conducted in collaboration with the City of Nampa, will evaluate the use of granular carbon as a concrete additive to improve early strength gain in bridge deck concrete while maintaining durability and workability. The study will examine how different carbon dosages affect concrete strength, workability, durability, permeability, shrinkage, thermal properties, and overall performance. Laboratory testing will be used to identify mix designs that balance strength, durability, constructability, and cost effectiveness. The project will also evaluate the potential for granular carbon to improve heat retention and reduce snow and ice accumulation on bridge decks.]]></description>

      <title>Modernization of Idaho StreamStats: Updates to Statewide Basin Characteristics and At-Site Peak Streamflow Statistics</title>
      <link>https://trid.trb.org/View/2742769</link>
      <description><![CDATA[The Idaho Transportation Department (ITD) is seeking to enhance the Idaho StreamStats application by incorporating updated basin characteristics, hydrography, and at-site peak streamflow statistics using current datasets, advanced geospatial technologies, and modern hydrologic analysis methods. StreamStats is an important tool used by transportation engineers, planners, and water resource professionals to estimate streamflow characteristics that support the design and maintenance of bridges, culverts, drainage infrastructure, and other transportation assets. This project will leverage high-resolution lidar-derived elevation data, updated land cover and climate datasets, improved hydrography, and current flood-frequency analysis methods to strengthen the accuracy, consistency, and reliability of hydrologic information available through StreamStats. Research activities will include updating basin characteristics, recalculating peak-flow statistics using recent streamflow records, integrating updated information into the StreamStats application, and publishing supporting datasets to promote transparency and future use. The resulting tools and workflows will provide ITD and its partners with enhanced hydrologic information to support infrastructure design, flood risk assessment, regulatory compliance, and long-term transportation planning.]]></description>

      <title>Sustainability Analysis of MICP-Treated High-Fines Soil with Geocell Reinforcement for Pavement Base Stability</title>
      <link>https://trid.trb.org/View/2678166</link>
      <description><![CDATA[This study explores sustainable pavement base strategies combining microbial-induced calcite precipitation (MICP) and geocell reinforcement as alternatives to traditional methods reliant on virgin aggregate extraction. Conducted on a section of US Highway 95 in Idaho, the trial treated high-fines soil with MICP and reinforced it with geocells, comparing performance against conventional aggregate base. Life cycle cost analysis and embodied carbon quantification over 40 years showed the MICP–geocell section achieved about 35% lower greenhouse gas emissions and 12% lower costs at a 5% discount rate. Benefits mainly stem from reduced aggregate use and maintenance, though emissions from urea and calcium chloride production partly offset these gains. Limitations include short-term monitoring, omission of end-of-life impacts, and eutrophication risks from ammonium byproducts. Overall, MICP with geocell reinforcement appears promising for sustainable pavement construction, but requires longer-term study and comprehensive environmental assessment.]]></description>

      <title>Guidance on Evaluating Quality and Determining Return on Investment for Internal and Third-Party Data Research Project</title>
      <link>https://trid.trb.org/View/2693719</link>
      <description><![CDATA[The Idaho Transportation Department (ITD) recognizes the challenge of selecting the best approach to making decisions around which data products are worth investing in and which ones may appear promising on the surface, but actually add little value to the agency’s business processes. In light of these challenges, ITD launched a research project to explore methods for evaluating the return on investment (ROI) of different data investment opportunities to aid in their decision-making processes. The goal of this research was to create both processes and tools that will enable ITD to make more standardized, objective decisions around data investments. This report covers the research findings that informed the development of two new data asset evaluation tools that ITD can use to vet data investment opportunities, avoid the potential data purchasing pitfalls, and present comprehensive documentation that thoroughly substantiates a decision to move forward with (or rule out) what can be significant resource outlays.]]></description>

      <title>Combining In-situ and Remote Sensing-Based Monitoring Methods to Improve the Efficiency and Accuracy of Landslide Monitoring Activities</title>
      <link>https://trid.trb.org/View/2693721</link>
      <description><![CDATA[Repeat LiDAR or photogrammetry surveys for conducting temporal and spatial studies of mass movements are an emerging part of landslide hazard monitoring research, including the use of sensors aboard small Unmanned Aircraft Systems (UAS). The ability to measure change at a site over time can be an important asset in identifying slopes that pose a significant hazard to people and infrastructure, especially when paired with on-site inclinometer data. Data acquisition of LiDAR with UAS provides numerous benefits compared to other traditional airborne or terrestrial platforms. Our overall research approach was to collect and integrate geotechnical, landslide geometry, displacement, weather and surface site condition data with UAS remotely sensed data for evaluation of landslide hazards at four landslide areas. Accurate repeat LiDAR studies can be difficult to achieve due to inherent issues from using different platforms and sensors including the use of different vertical datum such as geoids or ellipsoid reference systems, poor co-registration of flightlines, differences in data quality, resolution, or georeferencing software, classification changes, and changes in post processing steps. This study provides recommendations for data acquisition and processing protocols to overcome registration limitations, reduce uncertainty in change detection models, and describe best practices for monitoring landslide movement and characterization.]]></description>

      <title>Idaho Alive at 25 Young Driver Education Program Evaluation</title>
      <link>https://trid.trb.org/View/2693720</link>
      <description><![CDATA[Since 2009, the Idaho Transportation Department (ITD) has implemented the Alive at 25 national program in Idaho. Each year, thousands of young Idaho drivers participate in the program to learn how to be better and safer on the road. To date, the impact of this program on driver behaviors and attitudes is unknown. ITD contracted Boise State University’s Idaho Policy Institute (IPI) to study the program’s implementation over the past 13 years to better understand how the course is delivered in Idaho and how similar courses are implemented in other states. IPI analyzed data collected through 24 qualitative interviews, 24 years of crash and citation data, and three quantitative surveys of Alive at 25 course participants. Analysis suggests Alive at 25 is viewed favorably by both instructors and participants; demand for virtual course options is under-served; method of instruction does not appreciably impact student attitudes or behaviors; certain elements increase the likelihood of success in behavioral change programs; Alive at 25 curriculum is in needed-flux; the program’s impact on citation and crash occurrence is short-term; and attitudinal changes among participants appear similarly short-term.]]></description>
