  • ODOT Blue Lights in Work Zone Study - Case Study Data

    Creator:
    Gambatese, John A.
    Abstract:
    The dataset was generated as part of a study conducted by Oregon State University (OSU) and funded by the Oregon Department of Transportation (ODOT). The study, titled "Use of Blue Lights on Paving Equipment in Work Zones," was conducted from June to December 2018. The dataset includes vehicle speed and...

  • Consideration of Driver Behavior in the Design of Red Light Extension Systems

    Creator:
    McCrea, Sarah Anne
    Abstract:
    Red Light Running (RLR) is a safety hazard at signalized intersections in Oregon and throughout the United States. Various methods of mitigating factors contributing to RLR have been implemented but few protect against a conflict when a vehicles runs a red light. Additionally, current prediction algorithms are complicated; there is...

  • Enhanced sensors for vehicle dynamics evaluation

    Creator:
    Baratange, Francois
    Abstract:
    Vehicle dynamics evaluation is divided in two domains: ride quality and handling. The evaluation of characteristics related to both of these domains requires the knowledge of the vibrations developed by the vehicle. Vibrations can be described by acceleration, velocity or displacement (linear or angular). The inertial properties of large vehicles...

  • Design procedure for brushless doubly-fed machine used as a limited speed-range pump drive

    Creator:
    Alajmi, Abdulhadi M.
    Abstract:
    The continuing desire of industry to further improve process efficiency, through tighter control and energy conservation, has prompted users to pay closer attention to Adjustable Speed Drives (ASDs). The conventional ASDs consist of induction or synchronous motors controlled by power electronic controllers through the adjustment of supply frequency and line...

  • Analysis and design of the brushless doubly-fed machine

    Creator:
    Rochelle, Patrick R.
    Abstract:
    Use of conventional induction machines (IM) in adjustable speed drives (ASD) has increased in recent years. Electronic power processing has facilitated this increased use. The IM is an inexpensive and robust machine, but when used as part of an ASD, the cost of the system increases due to the inclusion...

  • Kinematic analysis of walking machine foot trajectory

    Creator:
    Su, I-chih
    Abstract:
    A method to design foot trajectory in Cartesian coordinates for a six-leg walking machine is presented in this thesis. The walking machine is based on the geometry of the darkling beetle. The walking procedure developed by Y.S. Baek is introduced first to provide step length and leg swing time for...

  • Fuzzy logic for improved dilemma zone identification : a simulator study

    Creator:
    Moore, Derek
    Abstract:
    The Type-II dilemma zone refers to the segment of roadway approaching an intersection where drivers have difficulty deciding to stop or proceed through at the onset of the circular yellow (CY) indication. Signalized intersection safety can be improved when the dilemma zone is correctly identified and steps are taken to...

  • Development of vehicle dynamics tools for motorsports

    Creator:
    Patton, Chris
    Abstract:
    In this dissertation, a group of vehicle dynamics simulation tools is developed with two primary goals: to accurately represent vehicle behavior and to provide insight that improves the understanding of vehicle performance. Three tools are developed that focus on tire modeling, vehicle modeling and lap time simulation. Tire modeling is...

  • Impact of asset usage preferences on parallel replacement decisions

    Creator:
    Wagner, Tristan John
    Abstract:
    Data from a state department of transportation fleet shows that the usage of a typical asset decreases as it ages. One possible explanation for decreasing asset usage with age is operator preference for using the newest available asset. In this research the long-term cost and replacement implications of such a...
