  • Safety performance of curve advisory speed signs

    Creator:
    Avelar Moran, Raúl Eduardo
    Abstract:
    Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...

  • Effectiveness of curve advisory speed signs : a characterization of road operations in western Oregon

    Creator:
    Avelar Morán, Raúl Eduardo
    Abstract:
    Posting advisory speed signs at sharp horizontal curve locations is a common practice in the U.S. These signs recommend drivers safe speeds to negotiate such curves. Literature indicates that adherence to advisory speeds is, in general, poor. Moreover, limited research is available that quantifies safety implications of these signs. This...

  • An Agent-Based Simulation for Emergency Warning Dissemination in a Multiplex Social Network

    Creator:
    Koll, Charles D.
    Abstract:
    The variety of natural disasters provide different sets of characteristics and properties with unique challenges. One significant difference between hazard types is prewarning lead time, the amount of time individuals have from a potential warning to the disaster occurring. Rapid onset disasters may not provide an official warning about a...

  • FATE group decision support system in transportation decision making

    Creator:
    Taekratok, Thaweesak
    Abstract:
    Two interesting challenges have been created in the traditional transportation planning process through recent adoption of more interactive roles by Federal, State and local transportation agencies and of those representing the communities being impacted by proposed transportation projects. First, the decision-making groups that formerly included solely transportation and related professionals...

  • Optimal sensor placement for measuring operating speeds through curves on rural two-lane highways

    Creator:
    Mecham, Megan E.
    Abstract:
    Operating speed is one of the best performance measures that can tell transportation agencies how well or how poorly the transportation system is functioning. Fluctuating operating speeds often mean there is a design flaw or something about the physical road design that violates drivers' expectations. A primary example of this...

  • 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...

  • 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...

  • Pedestrian safety at signalized intersections operating the flashing yellow arrow

    Creator:
    Tuss, Halston
    Abstract:
    At signalized intersections, pedestrians are considered to be amongst the most vulnerable. When in the crosswalk at intersections without protected left-turn phasing, pedestrians are particularly at risk from left-turning vehicles. Until recently, a wide variety of indications were in use across the US to indicate a permissive left-turn condition to...

  • Experimental study of counter-propagating solitary wave collisions

    Creator:
    Chen, Yongshuai
    Abstract:
    To better understand the extreme local amplification of tsunami, the experimental investigation on counter-propagating solitary wave collisions over a horizontal bottom was conducted using the optical measurement techniques: Particle Image Velocimetry (PIV), and Laser Induced Fluoresce (LIF). Head-on collisions and oblique collisions of equal-amplitude as well as unequal-amplitude waves were...

    Dharmapalan, Vineeth
    Abstract:
    Designing for construction safety is part of standard practice in countries such as the UK, Australia, and South Africa. Designing the permanent facility in a manner to eliminate or reduce the risks of injury, illness, or fatality of construction workers is defined as designing for construction safety (DfCS). Although evident...
