  • Evaluation of Dynamic Passive Pedestrian Detection with a Framework for Future Applications

    Creator:
    Larson, Travis O.
    Abstract:
    Intersections pose unique transportation challenges regarding safety and operational efficiency. When pedestrians currently want to cross at intersection, they need to use a push button to issue a call for service. The call is static and cannot be altered or changed. But by implementing dynamic passive pedestrian detection sensors, intersections...

  • Data-Driven Numerical Modelling of an Oscillating Water Column from Physical Tank Testing Data

    Creator:
    McKee, Aisha I.
    Abstract:
    Wave Energy Converters (WEC) have great potential to help meet global energy demands, but even a single device can be challenging to model. Although most WEC concepts are modelled, many have been simplified with assumptions that do not accurately capture the true dynamics of the system. For this reason, data-driven...

  • Evaluating Contributing Factors to Collision Types through Discrete Choice Analysis : An Application to Large-Truck Crashes in Washington State

    Creator:
    Dudich, Dejan
    Abstract:
    While there have been several efforts to understand large-truck crashes, the relationship between crash factors, crash severity and collision type is not clearly understood. Past studies have utilized different statistical or econometric models to predict the manner of collision at intersections, yet not much attention has been paid to the...

  • Effect of whole-body vibration on painful diabetic peripheral neuropathy

    Creator:
    Guzman, Ruben J.
    Abstract:
    Introduction. Painful diabetic peripheral neuropathy (DPN) is a common complication of diabetes that interferes with daily living and causes severe pain. Pharmacotherapy is the accepted treatment strategy, however, this strategy is associated with high cost, minimal reductions in pain, and adverse side effects. Thus, a critical need exists to develop...

  • An evaluation of gap acceptance behavior at unsignalized intersections

    Creator:
    Nabaee, Sahar
    Abstract:
    Gap acceptance behavior is critical to the safety and operational performance of unsignalized intersections. The complex nature of the human behavior and its dependence on various socioeconomic and environmental parameters makes it challenging for transportation professionals to assess the performance of such intersections. To investigate the behavioral patterns of drivers...

  • Effectiveness of curve advisory speed signs : a characterization of road operations in western Oregon

    Creator:
    Avelar Morán, Raúl Eduardo
    Abstract:
    Posting advisory speed signs at sharp horizontal curve locations is a common practice in the U.S. These signs recommend drivers safe speeds to negotiate such curves. Literature indicates that adherence to advisory speeds is, in general, poor. Moreover, limited research is available that quantifies safety implications of these signs. This...

  • Normal acceleration characteristics of the leading vehicle in a queue at signalized intersections on arterial streets

    Creator:
    Zhu, Hong
    Abstract:
    Normal acceleration characteristics of passenger cars provide valuable information for various aspects of transportation engineering, including use in the geometric designs of intersections, freeway ramps, passing lanes, acceleration lanes, turning bays, or in the development of traffic simulation or fuel consumption models. However, the data used in previous studies are...

  • Achieving Transparency in Human-Collective Systems

    Creator:
    Roundtree, Karina A.
    Abstract:
    Collective robotic systems are biologically-inspired and exhibit behaviors found in spatial swarms (e.g., fish), colonies (e.g., ants), or a combination of both (e.g., bees). Collective robotic system popularity continues to increase due to their apparent global intelligence and emergent behaviors. Many applications can benefit from the incorporation of collectives, including...

  • Right-hook crash causality at signalized intersections

    Creator:
    Jannat, Mafruhatul
    Abstract:
    A Right-hook (RH) crash is a common type of bicycle-motor vehicle crash that occurs between a right-turning vehicle and through-moving bicycle at an intersection. At signalized intersections, RH crashes can occur at the onset of the green or during the latter portion of the green phase. In spite of the...
