  • An evaluation of gap acceptance behavior at unsignalized intersections

    Creator:
    Nabaee, Sahar
    Abstract:
    Gap acceptance behavior is critical to the safety and operational performance of unsignalized intersections. The complex nature of the human behavior and its dependence on various socioeconomic and environmental parameters makes it challenging for transportation professionals to assess the performance of such intersections. To investigate the behavioral patterns of drivers...

  • 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...

  • Visual Search Patterns and Behavior of Left Turning Bicyclists at Roadway Intersections: A Field Study

    Creator:
    Burns, Patrick O.
    Abstract:
    This research effort considers bicyclist’s left-turn behavior at roadway intersections with varying levels of traffic control; specifically, seeking to address the question where do bicyclists look to acquire information. A demographic comparison was made to determine if factors such as gender or experience influence the nature of how a bicyclist...

  • Evaluation of alternative information signs in Oregon

    Creator:
    Neill, Justin Michael
    Abstract:
    The number of international inbound tourists to the United States has risen steadily. To serve these and other tourists best, traffic signs need to communicate information correctly across a potential language barrier. Of particular interest is the traffic sign intended to communicate directions to Tourist Information centers. While the general...

  • Safety and efficiency benefits of traffic signal countdown timers : a driving simulator study

    Creator:
    Islam, Mohammad Rabiul
    Abstract:
    Traffic signal countdown timers (TSCT) are innovative, practical and cost effective technologies with the potential to improve efficiency and safety at signalized intersections. The purpose of these devices is to assist motorists in decision making at signalized intersections with real time signal change information. While successful implementation of these devices...

  • 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...

  • Influence of Texting on Driver Glance Patterns and Vehicular Lane Position on Horizontal Curves

    Creator:
    Ellett, Makenzie A.
    Abstract:
    The use of in-vehicle technologies, such as mobile phones, while driving has proliferated in recent years. Most notably, drivers are using mobile phones to send and receive text messages while operating a vehicle with increasing frequency. The act of texting while driving poses a significant threat not only to the...

  • The Evaluation of Engineering Treatments for Right-Hook Crashes at Signalized Intersections with Bicycle Traffic

    Creator:
    Warner, Jennifer Lynn
    Abstract:
    A right-hook crash is a bicycle-motor vehicle crash between a right-turning motor vehicle and an adjacent through-moving bicycle. This study focuses on right-hook crashes that occur during the latter stage of the circular green indication at signalized intersections with shared right-turn and through lanes. The overall objective was to evaluate...

  • 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...

  • Implications of Red Signal Countdown Timers on Visual Attention of Oregon Drivers

    Creator:
    Wyman, Amy A.
    Abstract:
    Red Signal Countdown Timers (RSCTs) are devices placed at intersections to inform drivers of the time remaining on a red indication before it turns green, typically to improve intersection efficiency. This study examines the visual attention of Oregon drivers to circular red (CR) indications with RSCTs as compared to standard...
