  • Understanding Passenger Perception of Air Travel Safety Through Advanced Econometric Modeling

    Creator:
    Olsen, Aleah G.
    Abstract:
    Passenger security screening is a continuously evolving process and not much is known about how passengers perceive its effectiveness in keeping air travel safe. The provided thesis consists of two manuscripts that expand the literature on passenger perception of safety through the application of advanced econometric techniques. This thesis aims...

  • An Agent-based Evacuation Modeling of Underground Fire Emergency

    Creator:
    Xu, Yue
    Abstract:
    Increasingly congested surface transportation network in urban areas and grow-ing land values make underground transportation systems more attractive for high-ways (i.e., tunnels) and metro system compared to other options [1]. An underground transportation system can preserve the land above for recreational parks, commer-cial buildings, residential homes, or other purposes while...

  • 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...

  • Stochastic Characterization of Highway Capacity and Its Applications

    Creator:
    Dong, Shangjia
    Abstract:
    Highway capacity has traditionally been treated as deterministic. In reality, however, capacity can vary from time to time and location to location due to inclement weather, various driving behavior, traffic incident, bottleneck and workzone. This thesis aims to characterize the stochastic variations of highway capacity, and explore its applications. The...

  • Improving Fatigue Cracking and Moisture Resistance of Asphalt Mixtures

    Creator:
    Obaid, Ihsan A.
    Abstract:
    The resistance of asphalt concrete pavement to distresses such as fatigue cracking and permanent deformation is governed by how well the structure can resist loading under a variety of traffic and climate-related conditions. Asphalt binder type and content are typically the variables that pavement engineers can manipulate to render the...

  • Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

    Creator:
    Kopper, Neil H.
    Abstract:
    Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...

  • Interactive Genetic Algorithms for watershed planning : an investigation of usability and human-centered design

    Creator:
    Piemonti, Adriana Debora
    Abstract:
    Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...

  • An Interdisciplinary Agent-based Evacuation Modeling Framework: Seeking Convergence of Social, Natural, and Engineered Systems to Improve Life Safety in the Cascadia Subduction Zone

    Creator:
    Chen, Chen
    Abstract:
    Social scientists have studied people's responses to disasters for many decades, and behavioral commonalities and variations are summarized in different mental schemes/models in disaster studies. Integrating those findings from social science into evacuation simulation can improve simulation accuracy and eventually better support decision-making and disaster preparedness. However, this kind of...

    Creator:
    Williams, Keith E.
    Abstract:
    Three-dimensional laser scanning has revolutionized spatial data acquisition and can be completed from a variety of platforms including airborne (ALS), mobile (MLS), and static terrestrial (TLS) laser scanning. MLS is a rapidly evolving technology that provides increases in efficiency and safety over static TLS, while still providing similar levels of...

  • Roundabout Safety: Econometric and Machine Learning Models and Applications

    Creator:
    Zubaidi, Hamsa AN
    Abstract:
    The rapid growth in the number of roundabouts raises some significant research challenges, especially around safety performance and evaluation in the U.S. Despite the safety advantages that roundabout geometric design brings, crashes still occur. While operationally roundabouts are good at preventing severe crashes, they may lead to more less severe...
