  • Properties of geotextiles in cold regions applications

    Creator:
    Allen, Tony Michael
    Abstract:
    Geotextiles are experiencing increased use in arctic and subarctic construction in separation, reinforcement, erosion control, and drainage applications. The use of geotextiles as capillary cutoff layers to prevent frost heave has been proposed as well. In recognition of the need to investigate properties of geotextiles in cold regions applications, a...

  • 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...

  • Monitoring and Prediction of Severe Weather Phenomena through GNSS Meteorology

    Creator:
    Tahami, Hoda
    Abstract:
    While primary use of Global Navigation Satellite System (GNSS) is positioning, navigation, and timing (PNT), various GNSS applications have emerged over the past decades that includes GNSS meteorology. GNSS meteorology is the remote sensing of the atmospheric constituents in the neutral atmosphere – mostly in the troposphere - using GNSS...

  • 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...

  • Weather and large waves along the Oregon coast: atmospheric controls on a numerical wave model

    Creator:
    Ellenson, Ashley N.
    Abstract:
    In this study, the effects of implementing different wind input or physics packages in a numerical wave model to recreate large wave conditions are explored. Three large wave events are simulated with WaveWatch III. The wind inputs which are compared are NCEP's Global Forecasting System (GFS) with 0.5 degree resolution...

  • Unobserved Heterogeneity and Spatial Correlation: Statistical and Econometric Analyses of Heavy-Vehicle Hard Braking and Crash Frequency by Crash Type

    Creator:
    Anderson, Jason C.
    Abstract:
    This dissertation provides a comparison of statistical and econometric frameworks, using a previously unused freight data source, to study crash frequency by crash type and heavy-vehicle hard braking in Oregon. Hard braking can serve as a proxy for several factors, one of which is safety. Therefore, with the hard braking...

  • Optimal mixture of road network ownership

    Creator:
    Li, Mingxin
    Abstract:
    The present highway funding system, especially fuel taxes, may become less reliable revenue sources in the future, while the transportation public agencies do not have the sufficient financial resources needed to meet the increasing traffic demand. Regarding the socio-economic impact of road privatization, a wide range of approaches and models...

  • Bus accessibility for persons with sensory disabilities

    Creator:
    Hron, Martha
    Abstract:
    With the passage of the American with Disabilities Act (ADA) it has become a civil rights violation to deny access to persons with disabilities to public transportation. The ADA requires transit agencies to provide accessible buses or equivalent services to persons with mobility, sensory or cognitive impairments. This study examines...

  • Direction, method, and model for implementing design for construction worker safety in the US

    Creator:
    Tymvios, Nicholas
    Abstract:
    The construction industry employs about 7% of the total US workforce, and yet it accounts for 15.7% of all occupational fatalities. Specifically in 2011, there were 721 deaths in construction, second only to transportation with 733. The cause of a large number of these construction deaths can be attributed to...
