Federal Railroad Administration

rosaP Repository & Open Science Access Portal

The Federal Railroad Administration (FRA) promotes safe and environmentally sound rail transportation. The FRA conducts research and development tests to evaluate projects in support of its safety mission and to enhance the railroad system as a national transportation resource. Public education campaigns on highway-rail grade crossing safety and the danger of trespassing on rail property are also administered by FRA.

    Recognition of rail car retroreflective patterns for improving nighttime conspicuity
    Multer, Jordan
    ORCID ICON IMG
    2001-07-01 | PDF
    Every year in the United States, accidents at highway-railroad grade crossings take place where the motorist hits the side of the train at night. In a portion of these nighttime accidents, the motorist fails to see the train in the grade crossing. One proposed solution to prevent such accidents is to mount retroreflective material on the sides of r ...
