  • Low volume grade crossing treatments for the Oregon high speed rail corridor

    Creator:
    Zaworski, David D.
    Abstract:
    This study defines the information gathering and communication and response needed for safety at highway-rail crossings. It examines technologies for low-cost, high-safety treatments for low volume highway crossings of higher speed (130-200 kph) rail. Crossing closure and consolidation is a necessary first step. Existing train control and crossing safety systems...

  • 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...

  • 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...
