The purpose of this study was to develop guidelines and recommendations for the design of retroreflective marking systems to enhance the conspicuity of rail cars at night. Three methods were used to generate and evaluate the marking systems for a standard hopper car. First, a group of human...
Collisions at highway-railroad grade crossings have posed a significant safety problem. To reduce the number of these collisions at highway-railroad grade crossings where train visibility is a contributing factor, the Federal Railroad Administration (FRA) is investigating measures to enhance the...
The U.S. Department of Transportation, Research and Special Programs Administration, Volpe National Transportation Systems Center, in support of the Federal Railroad Administration is conducting a research program with the goal of reducing the number of fatalities and injuries at highway-...
Under sponsorship from the Federal Railroad Administration (FRA), Transportation Technology Center, Inc. (TTCI) evaluated five technologies for their ability to detect trains and/or highway vehicles approaching and occupying highway rail intersections. TTCI evaluated the performance of these...
This report describes testing of prototype vehicle proximity alert system (VPAS) technologies, and presents and evaluates the results. The object was to determine the feasibility of VPAS for possible use in priority vehicles (i.e., emergency vehicles, school buses, vehicles carrying hazardous...
This workshop was held June 11 and 12, 1998, at the U.S. Department of Transportation (DOT) John A. Volpe National Transportation Systems Center in Cambridge, Massachusetts. Participants included DOT staff and consultants, state highway and rail representatives, railroads, railroad suppliers,...
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...
This report, prepared at the direction of the U.S. Department of Transportation, examines safety, design, and liability issues associated with the development of shared use paths and other trails within or adjacent to active railroad and transit rights-of-way. This document is intended to...
The Federal Railroad Administration (FRA) has undertaken a rulemaking process to address the use of locomotive horns at public highway-railroad grade crossings [1]. This rule includes a provision to regulate the sound level output of railroad horns. This letter report supports the rulemaking by...
Five technologies were evaluated for their ability to detect trains and/or highway vehicles approaching and occupying highway railroad intersections. Tests were conducted on the performance of these technologies during October and November 1999 at the Federal Railroad Administration's...
