  • Innovative Applications of Real-World Vehicle Trajectories Collected with a Radar Vehicle Detection System

    Creator:
    Simpson, Ellen J.
    Abstract:
    Left turn movements are considered to be the highest risk movements through an intersection, and can result in head on, angle, or side impact crashes. The flashing yellow arrow (FYA) for use as a permissive left turn phasing indication is relatively recent, first appearing in the 2009 edition Manual on...

  • Evaluation of Dynamic Passive Pedestrian Detection with a Framework for Future Applications

    Creator:
    Larson, Travis O.
    Abstract:
    Intersections pose unique transportation challenges regarding safety and operational efficiency. When pedestrians currently want to cross at intersection, they need to use a push button to issue a call for service. The call is static and cannot be altered or changed. But by implementing dynamic passive pedestrian detection sensors, intersections...

  • 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...

  • Sound and Vibration Analysis of Alternative Rumble Strips

    Creator:
    Horne, Dylan Ross
    Abstract:
    Roadway departure crashes accounted for 18,275 fatal crashes in 2017 across the United States (Jones et al. 2017). Rumble strips (RS) provide audible and haptic interior alert when a vehicle is departing the roadway reducing run-off-the road crashes. Although inexpensive to install, and easy to maintain, RS are not installed...

  • Assessing the Impact of Three Intersection Treatments on Bicyclist Safety

    Creator:
    Scott-Deeter, Logan K..
    Abstract:
    Bicyclist safety at urban intersections is a critical element for encouraging an increase in bicycle commuting. With bicycle injury and fatality rates rising due to collisions with vehicles at signalized intersections, increasing the safety of riders continues to be an important consideration when promoting this mode of transportation. Previous research...

  • Evaluating Driver Response to the Onset of Circular Yellow Indication in the Presence of a Following Vehicle at Isolated High-Speed Signalized Intersections

    Creator:
    Mohammed, Hameed A.
    Abstract:
    Dilemma zones on the approach to high-speed signalized intersections have been identified as a safety problem that can contribute to rear–end and right–angle crashes. However, in situations when a pair of vehicles is caught in the dilemma zone, it is not well understood how the following vehicle’s headway and classification...

  • 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...

  • 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...

  • Evaluation of Cycling Behavior: Factors that Influence Bicyclists’ Comprehension, Comfort, and Stress

    Creator:
    Cobb, Douglas P.
    Abstract:
    Travel demand has increased due to population growth, increase of vehicle ownership, and development patterns resulting in greater levels of congestion, pollution, and crash frequency. One approach to demand management is to increase the share of trips made by bicycles. With the increase in bicycling rates, there is a critical...

  • 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...
