  • The performance of drivers with physical limitations at T-intersections

    Creator:
    Hunter-Zaworski, Katharine M.
    Abstract:
    The research examines the effect of restricted head and neck movement on driving performance as measured by decision time at T-intersections. The traffic safety and human factors literature was reviewed, and very little was found concerning drivers with physical limitations. T-intersections were selected for study because most accidents involving drivers...

  • Roles and responsibilities of school nurses in Benton, Clackamas, Lane, Linn, and Marion counties, Oregon

    Creator:
    Vongleang, Pattamaporn
    Abstract:
    A considerable number of research studies have been conducted in order to suggest a professionally desirable and practically feasible definition of the school nurse's role. Yet, the role of the school nurse remains unclear to both the lay public and the nursing profession. The main purpose of this qualitative research...

  • A GIS approach to estimating continuous hydraulic conductivity and equivalent hydraulic conductivity

    Creator:
    Arras, Tracy Lynn
    Abstract:
    Estimating the hydraulic conductivity of earth materials is important for many water resource modeling efforts, including predicting the transport of pollutants in ground water, computing surface runoff for flood control, and computing water budgets. This research implicitly used topography, soil, and climate data to estimate plausible continuous hydraulic conductivity values...

  • Sound and Vibration Analysis of Alternative Rumble Strips

    Creator:
    Horne, Dylan Ross
    Abstract:
    Roadway departure crashes accounted for 18,275 fatal crashes in 2017 across the United States (Jones et al. 2017). Rumble strips (RS) provide audible and haptic interior alert when a vehicle is departing the roadway reducing run-off-the road crashes. Although inexpensive to install, and easy to maintain, RS are not installed...

  • The effect of running speed and turning direction on lower extremity joint moment

    Creator:
    Lee, Ki-Kwang
    Abstract:
    Fast medio-lateral movements, frequent in a number of sports activities, are associated with lower extremity injuries. These injuries may occur as a result of excessive musculoskeletal stresses on the joints and their associate structures. The purpose of this study was to investigate the effect of running speed and turning movement...

  • Reducing sediment production from forest roads during wet-weather use

    Creator:
    Toman, Elizabeth Myers
    Abstract:
    Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...

  • Use of Flashing Lights in Traffic Safety of Vulnerable Road Users

    Creator:
    Ahmed, Ananna
    Abstract:
    Vulnerable road users, anyone interacting with the roadway facility without the protection of an automobile, experience greater risk for more severe crash outcomes. Multimodal roadway facilities often times provide less separation and more points of conflict between different types of road users. To promote vulnerable road user safety, transportation agencies...

  • Evaluating Driver Response to the Onset of Circular Yellow Indication in the Presence of a Following Vehicle at Isolated High-Speed Signalized Intersections

    Creator:
    Mohammed, Hameed A.
    Abstract:
    Dilemma zones on the approach to high-speed signalized intersections have been identified as a safety problem that can contribute to rear–end and right–angle crashes. However, in situations when a pair of vehicles is caught in the dilemma zone, it is not well understood how the following vehicle’s headway and classification...

  • 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...
