    Autonomous Vehicles for Small Towns: Exploring Perception, Accessibility, and Safety
    Li, Wei ;
    Ye, Xinyue
    2023-09-01 | PDF
    As of 2021, there were 18,696 small towns in the US with a population of less than 50,000. These communities typically have a low population density, few public transport services, and limited accessibility to daily services. This can pose significant challenges for residents trying to fulfill essential travel needs and access healthcare. Autonomou ...

  • Guiding Driver Responses During Manual Takeovers from Automated Vehicles [supporting dataset]
    Greatbatch, Richard ;
    Dunn, Naomi J.
    2023-08-23 | ZIP
    The number of automated features in surface vehicles is increasing as new vehicles are released each year. Some features allow drivers to temporarily take their attention off the road to engage in other tasks. However, sometimes it is important for drivers to immediately take control of the vehicle. To take control safely, drivers must understand w ...

    Truck Platooning Effects on Girder Bridges: Phase II-Service
    Steelman, Joshua S. ;
    Puckett, Jay A.
    2023-08-11 | PDF
    Truck platooning—wirelessly linking two or more trucks to travel in a closely spaced convoy—is federally promoted to save fuel, improve the environment, and improve traffic operations. Platooning places trucks much closer than current design codes anticipate. While this strategy can provide higher fuel efficiency, it also can potentially overload s ...
  • Safety Assurance System Utilizing Visual Attention for Advanced Driver-Assistance Systems [supporting datasets]

    Young, Chandler
    2023-08-01 | PDF
    There are numerous applications of the Autonomous Maintenance Technology (AMT) that have yet to be fully utilized or widely shared. There are many slow-moving operations conducted by Departments of Transportation (DOTs) with an attenuator (e.g., work zone set up, operations, take down, repairs, mowing, sweeping), platooning of two or more vehicles ...
  • Access Control at MajorMinor Road Intersection Through CAV in Mixed Traffic
    Access Control at Major/Minor Road Intersection Through CAV in Mixed Traffic
    Yi, Ping
    2023-08-01 | PDF
    Roadway intersections are among the major causes of traffic congestion besides lane reduction bottlenecks. When a major road intersects a minor road at an unsignalized intersection without the control of a traffic signal, the mainline vehicles are given priority over the minor road vehicles to go through the intersection, and the latter can only en ...
