  • Limit Equilibrium-Based Assessment of the Internal Stability of Geosynthetic Reinforced Soil Structures Subject to Seismicity

    Creator:
    Loving, Carly K.
    Abstract:
    Design of Geosynthetic-Reinforced Soil Structures (GRSS) require sufficient rear pullout anchoring capacity in order to maintain internal stability. Length requirements are amplified when reinforcement coverage ratios or seismicity is considered, potentially resulting in uneconomical GRSS design lengths. This study describes the influence of reinforcement length, coverage ratio, and pseudostatic seismic...

  • The evolution of practical safety audits in the United States

    Creator:
    Houghton, Tegan Marie
    Abstract:
    This thesis evaluates pre-construction auditing procedures used in the United Kingdom, Australia, and New Zealand in order to help create post-construction auditing procedures for the state of Oregon. It was funded as part of the development of the Oregon Department of Transportation (ODOT) Safety Investigation Manual, and also evaluates content...

  • The Influence of Management Actions on Project Success Concerning Cost, Time, and Quality

    Creator:
    Alabdumunem, Mohammed K.
    Abstract:
    In the construction industry, people seek to deliver a successful project. The major success performance measurements in the construction industry are cost, time, and quality. Several researchers have determined critical success factors for construction projects, and one of these critical success factors was management actions. Furthermore, there is an inadequacy...

  • An Empirical Study of Work-zone Safety and Mobility Using Surveys and Anonymous User Generated Trip Information

    Creator:
    Fiawoyife, Kenneth K.
    Abstract:
    The two primary considerations for highway work-zones are its effect on commuter mobility and worker safety which are often spoken of together. However, it must be noted that they often conflict with each other. For example, traffic control plans that reduce travel speed in work-zones improve both commuter and worker...

  • 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...

  • Optimal sensor placement for measuring operating speeds through curves on rural two-lane highways

    Creator:
    Mecham, Megan E.
    Abstract:
    Operating speed is one of the best performance measures that can tell transportation agencies how well or how poorly the transportation system is functioning. Fluctuating operating speeds often mean there is a design flaw or something about the physical road design that violates drivers' expectations. A primary example of this...

  • Impact of access density on number of crashes at commercial roadways

    Creator:
    Yi, Xiang
    Abstract:
    Numerous research efforts have proven the safety benefits of access management. There are several access management techniques, including unsignalized access spacing, signalized intersection spacing, left-turn lanes, right-turn lanes, Two-Way Left-Turn lanes (TWLTLs), nontraversable median, U-turns, interchange access separation distances and so on. This project explores the correlation between access density...

  • Regional and Site-Specific Vulnerabilities of the Western Power Grid from a M9.3 Cascadia Subduction Zone Earthquake

    Creator:
    Lathrop Eve D.
    Abstract:
    The likelihood of a Cascadia Subduction Zone (CSZ) earthquake is estimated between 37 to 42% in the next 50 years, leading to strong shaking, liquefaction, landsliding, and other seismic ground failure resulting in major impacts to critical lifelines such as the western power grid. Electrical power is essential for continued...

  • Behavior of a compliant wave-current barrier

    Creator:
    Kerper, Dale R.
    Abstract:
    This study includes an analytical solution to the wave-current barrier interaction problem and large scale experiments to validate the theory. The boundary value problem is solved mathematically by characterizing the flow field and barrier motion separately, then coupling the relationships with the appropriate kinematic and dynamic boundary conditions. The flow...

  • A validation of the Oregon State University driving simulator

    Creator:
    Brown, Lacy S.
    Abstract:
    Driving simulation is widely accepted as a safe, effective, and economical alternative for investigating driver behavior in a variety of contexts. However, in order to apply simulator-based research results to real-world settings, the performance measures acquired through simulated driving experiments must first be validated. This research was aimed at validating...
